average, it is not surprising that the overall temperature was close to 5
degrees above average. This made it the
second warmest February in the history of weather records in the region (which
go back to 1914) and just a bit less than the record warmest in 2017.</p><p class="MsoNormal"><o:p></o:p></p><p class="MsoNormal">Looking at the meteorological winter
(December-January-February), the average temperature was -1.8°C. This was the third warmest winter only behind
2001-02 and 1931-32.</p><p class="MsoNormal"><o:p></o:p></p><p class="MsoNormal">Even some wet days in the final few days of the month could
only bring the total precipitation to about a third of the average (21.6 mm
total compared to the average of 63.5 mm).
This was the driest February since 1987.</p><p class="MsoNormal"><o:p></o:p></p><p class="MsoNormal">With the warm temperatures and lack of overall precipitation,
it follows that the total snowfall of only 13 cm was well below the average of 30.3
cm for February. Overall, we have had
59.5 cm during this snowfall season, less than half the average of 125.6 cm for
this point in the season. As well, the
gloominess index of 5.9 (on a scale of 10) was just a bit less than the average
of 5.7 and much less than the value of 8.3 from last month.</p><p class="MsoNormal"><o:p></o:p></p><p class="MsoNormal">It is also that time of year for the annual Weather Station
Contest where you have to guess when the first time the station’s temperature
will go above 20°C. You can get details

Each day is given a number from 1 to 10 depending on the maximum amount of sun for that day, the gloomier the day the higher the number. Then the average for the month is then calculated. </p><p>For January the average was 8.3 (out of 10), this compares to the 1999-2023 average of 7.1 (it has ranged between 6.5 in 2013 to 8.5 last year). This was the second highest gloominess index in the history of the station, so it wasn’t just your imagination, there wasn’t a lot of sun last month.</p><p>Even though we had that one cold week in the middle of the month, it didn’t make up for the warmer than average temperatures the rest of the month, particularly near the end. In fact, the low temperatures in the last week never went below the average high temperatures for those days. With all that it is not surprising that the overall temperature was almost 3 degrees higher than average.</p><p>The total precipitation of 72.4 mm was just a little above the average of 70.9 mm. But even with the warm temperatures, we still got 36.5 cm of snow in January, not that far off of the average of 43.7 cm. Overall for the snowfall season we have had 46.5 cm, less than half the average of 95.3 cm for this point in the season.</p><p>Summary for January 2024:</p><p>Maximum Temperature 7.3°C<br />Minimum Temperature -19.5°C<br />Average Daily High Temperature -1.0°C (Long term average -2.4°C)<br />Average Daily Low Temperature -6.2°C (Long term average -10.6°C)<br />Total Precipitation 72.4 mm (Long term average 70.9 mm)</p><div><div>(Long term averages based on 1998-2022 data from the Soulis Memorial Weather Station at the University of Waterloo)</div><div><br /></div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhTHdCItEgx0Ou0i0Lrqsw0Jb4-vKeJ4rrtOke0tr6hxePGpT-WCE7CQeV0Gm-cwcojta6CqUasM2LbZlIn8jaRVgozfQd0Er6qhdf7WZB0JXztC8KmT3UqvrpCrpO0-J9mT6-MhaB43eNitgbX7f_FW92TfLT482SV2J4Mzk3bA4zjr3-oS1o9g8tBUfMW/s1941/202401.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1941" data-original-width="1500" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhTHdCItEgx0Ou0i0Lrqsw0Jb4-vKeJ4rrtOke0tr6hxePGpT-WCE7CQeV0Gm-cwcojta6CqUasM2LbZlIn8jaRVgozfQd0Er6qhdf7WZB0JXztC8KmT3UqvrpCrpO0-J9mT6-MhaB43eNitgbX7f_FW92TfLT482SV2J4Mzk3bA4zjr3-oS1o9g8tBUfMW/s320/202401.png" width="247" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><br /></div><br /><div class="separator" style="clear: both; text-align: center;"><br /></div><div><br /></div>Frankhttp://www.blogger.com/profile/05902865763952811195noreply@blogger.com1tag:blogger.com,1999:blog-1896989304324119352.post-11326568583503453142024-01-07T15:48:00.003-05:002024-01-07T15:48:18.269-05:002023 Annual Summary<p> <b style="font-family: "times new roman", serif;">E.D. Soulis Memorial Weather Station at the University of Waterloo Annual Summary - 2023</b></p><div><span style="font-family: "times new roman" , serif;"><div class="separator" style="clear: both; text-align: center;"><div class="separator" style="clear: both;"><div class="separator" style="clear: both; text-align: left;">The big story of 2023 was the heat throughout the year with only one month of below average temperatures. Although globally 2023 was the warmest year on record, in the region it was the fourth warmest year in the history of weather records in the region which go back over 100 years. The top four warmest years locally are: 2012 with an average temperature of 9.32°C, 1998 at 8.98°C, 2021 at 8.89°C, and now 2023 coming in at 8.86°C.</div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">The year started off very warm with the January coming in as the fourth warmest and February the sixth warmest. March was then close to average, before another warm month in April. That month the temperature reached 26.0°C or more for 5 straight days, this was the first streak that long during April. Also, with a temperature of 28.1°C on April 13, it was the earliest in the year that the temperature has gone above 28°C (previously it was April 22). With all that it isn’t surprising that it was the third warmest April in the region.</div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">The last below zero temperature occurred on May 18th, this was 12 days later than the average in the last 25 years and the second latest during that time. The month of May started a three month streak of temperatures that were close to average.</div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">August had an overall temperature that was 1.3 degrees below average, this was the only month that was below average during the year and the coolest August since 2008. Then in September we saw the first warmer than average month since April the warmest September in the last 5 years. There were 3 days above 30°C where we usually only see one of those every couple of years in September. Finally, the 32.0°C that occurred on the fifth was the warmest temperature for the entire year.</div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">There was a very hot streak the first week of October with 3 days close to 30°C, that contributed to the overall temperature being a little over a degree and half above average, that made it the fourth warmest October in the region. A little after midnight on the 23rd, the temperature went below zero for the first time since May 18th, which is about 10 days later than the average. With the frost-free period from May 18 to Oct 23, the frost-free season lasted 158 days, which is very close to the average of 160 days.</div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">November dipped a bit below average followed by the second warmest December on record at 4 degrees above average. The low temperature for the month of -6.9°C on the 13th, this was the highest for December in the history of records in the region.</div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">Looking at precipitation, the year started out very wet between January and April, this included February which was the most above average of any month since October 2021. There was one particularly wet day on the ninth when there was 35.6 cm of precipitation (the fourth wettest single day in February). While March was the second wettest in the last 10 years.</div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">May then broke the trend with only about half the average for the month ending with 11 days of no precipitation. Things turned around again in July which was the wettest since 2014 and in the top 10 in the history of weather records in the region. </div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">September was very dry, the 18.0 mm of precipitation made it the 4th driest on record and the direst since 1969. The rest of the fall was close to average, resulting in a total for the year of 958.8 mm, above the average of 869.6 mm, but still within the average range.</div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">The total snowfall for the 2022-23 season was a total of 119.5 cm, which was well below the average of 159.7 cm. The first few months of the next snowfall season has started slowly with only 10 cm total in November and December compared to the average of 26 cm by the end of the year.</div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">Frank Seglenieks</div><div class="separator" style="clear: both; text-align: left;">weather@uwaterloo.ca</div><div class="separator" style="clear: both; text-align: left;">E.D.

Around 80% of the people who responded thought we should start to use the 25 years of data from the Soulis Weather Station rather than waiting for the updated 30 year averages from Environment and Climate Change Canada. More details on the differences of making this change will come later, but for right now let’s just concentrate on the changes for this month.<br /><br />Apart from a few days over 30°C at the beginning of the month and one at the end, most of the rest of the month were consistently in the high 20s. Here we have the first consequence of the change of the averages, using the old averages it would have been a bit less than degree warmer than average. However, with the new averages this goes down to only 0.1 degrees, which is now within the average range. <br /><br />It was a consistently wet month with 4 days over 20 mm of rain, resulting in a total of 159.2 mm. This is well above the average of 78.2 mm (it would have also been well above the previous average of 98.6 mm) and quite the contrast to last year when we only got 18.7 mm. It was also the wettest July since 2014 and in the top 10 in the history of weather records in the region. <br /><br />The very wet month put the total for the year of 635.6 mm well above the average of 459.3 mm (the previous average for this time of year was 509.0 mm).<br /><br /><br />Summary for July 2023:<br />Maximum Temperature 32.0°C<br />Minimum Temperature 10.7°C<br />Average Daily High Temperature 26.5°C (Long term average 26.5°C)<br />Average Daily Low Temperature 15.1°C (Long term average 14.8°C)<br />Total Precipitation 159.2 mm (Long term average 78.2 mm)<br /><br />(Long term averages based on 1998-2022 data from the Soulis Memorial Weather Station at the University)<br /><br /></div><div><br /></div><div><br /></div><div><br /></div><div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgsut3MXhQFpLQm_itoLDnQ6Gi7pRDZ_n_sKmfKe-aIQ_wkvBI3TRDJQL-A4LNRqTpE4PVvO_cot43eg-swvDaVJKTekLrk17L7Ho3lf7DRUFFJaOdiT6hYJZDFWk5kBq5Kk-gaDkRJUsfmBBgRYBHwfQc6MHq0KNxFDPwnKKsYqATYgJ3MX6TUmJd22lTI/s1941/202307.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1941" data-original-width="1500" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgsut3MXhQFpLQm_itoLDnQ6Gi7pRDZ_n_sKmfKe-aIQ_wkvBI3TRDJQL-A4LNRqTpE4PVvO_cot43eg-swvDaVJKTekLrk17L7Ho3lf7DRUFFJaOdiT6hYJZDFWk5kBq5Kk-gaDkRJUsfmBBgRYBHwfQc6MHq0KNxFDPwnKKsYqATYgJ3MX6TUmJd22lTI/s320/202307.png" width="247" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><br /><div class="separator" style="clear: both;"><br /><br /></div></div></div>Frankhttp://www.blogger.com/profile/05902865763952811195noreply@blogger.com1tag:blogger.com,1999:blog-1896989304324119352.post-41641022761968133472023-07-02T16:33:00.000-04:002023-07-02T16:33:55.143-04:00June 2023 Summary<p><b> A very average June for both temperature and precipitation</b> </p><p>Really not that much to say about the temperature during the month of June.

In between there were some hot and some cold days, this made the overall temperature just slightly (0.1 degrees) above average.</p><p class="MsoNormal">As well, with the lack of precipitation (see below) and consequently lack of clouds, it made the daytime highs just a bit higher (1.6 degrees above average) and the nighttime lows just a bit lower (1.5 degrees below average). </p><p class="MsoNormal">The last below zero temperature was May 18th, this is 12 days later than the average in the last 25 years of the Soulis Weather Station and the second latest during that time. </p><p class="MsoNormal">But maybe a bigger story was the lack of precipitation, particularly the 11 days of dry weather to end the month. About two thirds of the total precipitation of 31.6 mm came down during the first week, not leaving much for the rest of May, which typically has an average of 82.3 mm.</p><p class="MsoNormal">The first four months of the year were very wet, so even after this dry month, the total for the year of 405.6 mm is still well above the average of 340.2 mm.</p><p class="MsoNormal">Thanks to everyone who came out the to the 25th anniversary open house, it was great meeting people who are interested in the station, answering questions, and showing off the weather station equipment. As you may have also noticed we have also renamed the station after the late professor Eric (Ric) Soulis, who was of course the driving force behind creating the station.

<p class="MsoNormal">Even a relatively cool second half of the month couldn’t
make up for the extremely hot week that occurred in the middle. From April 12-16 the temperature reached 26.0°C
or more for 5 straight days, this was the first streak that long during April
in the history of records in the region.
Also, with a temperature of 28.1°C on April 13, it was the earliest in
the year that the temperature has gone above 28°C (previously it was April 22).</p><p class="MsoNormal"><o:p></o:p></p>
<p class="MsoNormal">The overall temperature was 2 degrees higher than the average,
making it the third warmest in the 25 year history of the UW Weather Station.</p><p class="MsoNormal"><o:p></o:p></p>
<p class="MsoNormal">April had two days with over 25 mm of precipitation, these
along with a few other wet days were enough to make up for a dry week during
the month. The total precipitation was
115.6 mm compared to the average of only 74.5 mm.</p><p class="MsoNormal"><o:p></o:p></p>
<p class="MsoNormal">This month continues the wet pattern we have seen so far
this year, the total for the year (374.0 mm) is well above the average at this
time of year (264.4 mm).</p><p class="MsoNormal"><o:p></o:p></p>
<p class="MsoNormal">The total snowfall that came down during the month of 1.0 cm
was a lot less than the average of 7.3 cm.
This puts the total for the snowfall season at 119.5 cm, well below the
average of 159.7 cm.</p><p class="MsoNormal"><o:p></o:p></p>

This was the third warmest winter only behind 2001-02 and 1931-32. </div><div><br /></div><div>Overall, the month of February saw 85.0 mm of precipitation, well above the average of 54.9 mm, more than any month last year and the most since October 2021. There was one particularly wet day on the ninth when we had 35.6 cm of precipitation (the fourth wettest single day in February).</div><div><br /></div><div>With over 2 weeks during the month when we received no snow, the few storms in the last week only got the snowfall total to 22.0 cm, well below the average of 30.3 cm for February. The total since the Fall is now 97.0 cm, which compares to 125.6 cm for this point in the snowfall season.</div><div><br /></div><div>It is also that time of year for the annual UW Weather Station Contest where you have to guess when the first time the station’s temperature will go above 20°C.

This made it the fourth warmest January in the history of weather records in the region which go back over 100 years. The last warmer one was in 2006 and then you have to go all the way back to 1932 and 1933.</div><div><br /></div><div>Coming off a very dry year overall, it is sort of notable that the first month of this year was even just an average month for precipitation. The total of 68.4 mm was only a bit above the average of 65.2 mm.</div><div><br /></div><div>In the first 20 days of January we only had 4.0 cm of snow at the UW Weather Station, this is the lowest for the beginning of January since 1957. The 17.5 cm that fell on the 26th helped put the total snowfall for the month at 35.0 cm, which is less than the average of 43.7 cm. Overall for the snowfall season we have had 75.0 cm, below the average of 95.3 cm for this point in the season.</div><div><br /></div><div>And one last thing, a topic of conversation last month was how cloudy and gloomy it was, particularly to start the month. Some people didn’t think we would ever see the sun again. This is something that is hard to quantify, but choosing an arbitrary value for incoming solar radiation, let’s call it a dreary day when it doesn’t go above 400 Watts per square metre. This year there were 23 dreary days this January, since the UW weather station was established in 1998 (hey isn’t that 25 years ago?) this is the highest number for that month (2011 is second with 18). </div><div><br /></div><div>Summary for January 2023:</div><div>Maximum Temperature 4.4°C</div><div>Minimum Temperature -17.9°C</div><div>Average Daily High Temperature 0.6°C (Long term average -2.6°C)</div><div>Average Daily Low Temperature -4.5°C (Long term average -10.3°C)</div><div>Total Precipitation 68.4 mm (Long term average 65.2 mm)</div></div><div><br /></div><div>(Long term averages based on 1981-2010 data for the Waterloo-Wellington Airport)</div><div><br /></div></div><div><br /></div><div><div class="separator" style="clear: both; text-align: center;"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjt5Ep18U3dMsQl2J91_7xoj6X8_emJRdfgUcTCXqPZ3Nl0hR1AnkDFdzmhQA9mXgfRTaih_BPwNBlazw4eh200IKkRRrXskEhoQmubf22IR09NhnmPzUuAFVlD5iBwfec_XdHHSKvY4_dRewGHrKylTXjgNeOJj-4Dgswhb25HPlAb-Pa8nv_3e1Me4w/s1941/202301.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1941" data-original-width="1500" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjt5Ep18U3dMsQl2J91_7xoj6X8_emJRdfgUcTCXqPZ3Nl0hR1AnkDFdzmhQA9mXgfRTaih_BPwNBlazw4eh200IKkRRrXskEhoQmubf22IR09NhnmPzUuAFVlD5iBwfec_XdHHSKvY4_dRewGHrKylTXjgNeOJj-4Dgswhb25HPlAb-Pa8nv_3e1Me4w/s320/202301.png" width="247" /></a></div><br /><div class="separator" style="clear: both;"><br /></div><div class="separator" style="clear: both;"><br /></div></div></div>Frankhttp://www.blogger.com/profile/05902865763952811195noreply@blogger.com2tag:blogger.com,1999:blog-1896989304324119352.post-45418143631842597862023-01-07T15:08:00.000-05:002023-01-07T15:08:09.100-05:002022 Summary<p><b><span style="font-family: times; font-size: medium;">University of Waterloo Weather Station Annual Summary - 2022</span></b></p><p><span style="font-family: times; font-size: medium;">There was 1 big weather story for 2022: how dry it was throughout the year! </span></p><p><span style="font-family: times; font-size: medium;">With only 580.3 mm of precipitation, it was the sixth driest year since weather records began the region in 1914 and the lowest total precipitation since the 540.4 mm in 1963 (by the way, the lowest on record was 399.0 mm in 1937). February was the only month that had above average precipitation, 3 months were in the average range, and the rest were all drier than average. Anyone who had a hard time keeping a garden alive or watching their grass turn brown will remember just how dry it was, particularly during the summer.</span></p><p><span style="font-family: times; font-size: medium;">It was only a bit drier than average for the first three months of the year, then started the pattern we would see for the rest of the 2022. It was the driest April in the last 10 years, coming in at around 30 mm less than the average, while May was 20 mm less.</span></p><p><span style="font-family: times; font-size: medium;">Then came the peak dryness during the months from June to September, overall for those months we had less than 40% of the average. June and July had the least precipitation since 2007 and 2001, respectively, while July, with only 18.7 mm, was the fifth driest July on record and the least amount for any month since March of 2014. </span></p><p><span style="font-family: times; font-size: medium;">Continuing the pattern, August only saw a little more than half the average precipitation and was the driest since 2010. At only 22.2 mm of precipitation, September was the fourth driest for that month since records began in the region and we have to go back to 1998 to find one with less precipitation.</span></p><p><span style="font-family: times; font-size: medium;">Then October and November were the driest since 2008 and 2012, respectively. December finally had very close to average precipitation, although it was close, as almost half of the month’s total came during the last two days of the month.</span></p><p><span style="font-family: times; font-size: medium;">Looking at temperature, the year started out with a very cold January, with an overall temperature that was almost 4 degrees below average. This was the most below average of any month since February of 2015. The low temperature of -32.4°C on the 29th was the second lowest temperature we have seen since the UW Weather station was established back in February of 1998 (the all-time low was -35.5°C on Feb 16, 2015).</span></p><p><span style="font-family: times; font-size: medium;">During the next few months, the temperature swung back and forth between being warmer and colder than average. Here are a couple of notable days in first half of 2022: The high of 25.9°C on the 24th of April was the second highest April temperature in the last 10 years. While the high on June 21st of 34.1°C was the highest temperature since the 34.5°C on July 9, 2020 and it was also the highest June temperature since June 27, 2005 when it was 34.9°C.</span></p><p><span style="font-family: times; font-size: medium;">The last six months of the year were much warmer at 1.2 degrees above average, with only July coming in below average (and that was only by 0.07 of a degree).</span></p><p><span style="font-family: times; font-size: medium;">The most notable longer stretch of temperatures was a 2 week period at the end of October and the start of November when the average high was 16.3°C, which is about 8 degrees higher than the average for that period. The high of 23.4°C on November 5th was only the fourth time on record we have seen a November temperature above 23°C.</span></p><p><span style="font-family: times; font-size: medium;">As far as the snowfall season of 2021-22, the total was 176.5 cm, well above the average of 159.7 cm. Between January 17 and 18, a total of 33.0 cm of snow came down, this was the second or third highest snowfall total for a single storm since we started measuring daily snowfall at the station in 2001. The single day total for the 17th was 22.5 cm making it the highest single day total since March 9, 2005 when we had 31.5 cm.</span></p><p><span style="font-family: times; font-size: medium;">Frank Seglenieks</span></p><p><span style="font-family: times; font-size: medium;">weather@uwaterloo.ca<br />University of Waterloo Weather Station Coordinator</span></p><p><span style="font-family: times; font-size: medium;">Summary for 2022 (averages from 1981-2010 data for the Waterloo-Wellington Airport):</span></p><p><span style="font-family: times; font-size: medium;">Average Daily High Temperature: 13.26°C (average 12.05ºC)<br />Average Daily Low Temperature: 1.15°C (average 1.94ºC)<br />Total Precipitation: 580.3 mm (average 916.3 mm) </span></p><p><span style="font-family: times; font-size: medium;">As the UW Weather Station was not operating for most of 2022 no extremes are being reported </span></p><p><span style="font-family: times; font-size: large;">Click on the image below to see the temperature chart:</span></p><div><span style="font-family: times new roman, serif;"><br /></span></div><div><span style="font-family: "times new roman" , serif; font-size: 12pt;"><div class="separator" style="clear: both; text-align: center;"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjQZxpaAEHN1zFJ2UsNAIWp2fOsWcMDtA-NeFYg4QMD0ju3CLsZ-npx-4kczgM-PMzqEElV4SlNNO4doSS_5Ct1TkeJW_6MQKmlRUWh8yU-QbdLTPsL0Q1GTk7CSPAIKRjU_4ku6q7z8em6yN1imNNagAk-HXOuSYmeNpeEW0PYdhxHiIWAdZWXTyX8Kg/s5379/2022-annual_temperature.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3754" data-original-width="5379" height="223" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjQZxpaAEHN1zFJ2UsNAIWp2fOsWcMDtA-NeFYg4QMD0ju3CLsZ-npx-4kczgM-PMzqEElV4SlNNO4doSS_5Ct1TkeJW_6MQKmlRUWh8yU-QbdLTPsL0Q1GTk7CSPAIKRjU_4ku6q7z8em6yN1imNNagAk-HXOuSYmeNpeEW0PYdhxHiIWAdZWXTyX8Kg/s320/2022-annual_temperature.png" width="320" /></a></div><br /><br /></div>Click on the image below to see the precipitation chart:</span></div><div><span style="font-family: times new roman, serif;"><br /></span><div><div class="separator" style="clear: both; text-align: center;"><div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj2SdEoNbJtjbPAuYFOtHjqaH38Qt3ksW9JL7agX2-sLMU1KSxLUfTNuRGvmWkLenOF5U4AWJsuqYmYvbGmfc5aNfjrrfPzmenE9M98ffpB5qqdj7drbxkl8-ryya5bJ9Ta5y3t85MMjkeHAWkMgYOM9QJF6FRIyApzVCeSkrR006v36ztJWjgN13OzmA/s5380/2022-annual_precipitation.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3754" data-original-width="5380" height="223" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj2SdEoNbJtjbPAuYFOtHjqaH38Qt3ksW9JL7agX2-sLMU1KSxLUfTNuRGvmWkLenOF5U4AWJsuqYmYvbGmfc5aNfjrrfPzmenE9M98ffpB5qqdj7drbxkl8-ryya5bJ9Ta5y3t85MMjkeHAWkMgYOM9QJF6FRIyApzVCeSkrR006v36ztJWjgN13OzmA/s320/2022-annual_precipitation.png" width="320" /></a></div><br /><div class="separator" style="clear: both;"><br /></div><br /><div class="separator" style="clear: both;"><br /></div></div><div style="text-align: right;"><br /></div></div><center><br /></center></div></div>Frankhttp://www.blogger.com/profile/05902865763952811195noreply@blogger.com1tag:blogger.com,1999:blog-1896989304324119352.post-53577334019519142972023-01-01T14:26:00.000-05:002023-01-01T14:26:15.681-05:00December 2022 Summary<p><b>A warm December with average precipitation</b></p><div><div>Apart from a few cold days just before Christmas, it was generally at or above average for the rest of the month.

record</b></p>
<p class="MsoNormal">After 2 months that were colder than average, the month of
August came in a bit more than 1 degree higher than average. This is not surprising with 5 days above 30°C
compared to the average of only 2 and only a few very cold days.</p><p class="MsoNormal"><o:p></o:p></p>
<p class="MsoNormal">We only received 44.8 mm of precipitation, which is just a
little more than half the average of 83.9 mm.
This made it the driest August since 2010 and put the total precipitation
so far in 2022 of 386.7 mm closer to the average of 596.0 mm. This is the sixth driest first 8 months of
the year that we have seen in the region.</p><p class="MsoNormal"><o:p></o:p></p>
<p class="MsoNormal">The total precipitation for this year’s meteorological
summer (June, July, and August) was 112.1 mm.
This is the second lowest total precipitation for these months in the
over 100 year history of records in the region, the only drier summer was in
2007 when there was only 74.5 mm.</p><p class="MsoNormal"><o:p></o:p></p>

The result was an overall temperature that was just 0.1 degrees below average, which is within the average range. </p><p>Although there were 8 days at or above 30°C compared to an average of 3.6, including 6 of them in a row, it was still the coolest July since 2014. </p><p>As always, the lawns and gardens around town showed just how dry it was during the month. With only 18.7 mm of total precipitation, it was the fifth driest July in the region since began over 100 years ago (with a special shout out to 1916 when only 1.8 mm was recorded, although the 3rd day of the month was missing) and the driest since 2001.</p><p>Also, there was some talk during the month about storm systems which came through Southern Ontario that would split or fade out before hitting Waterloo region. Well according to the map below of the precipitation anomaly from Environment and Climate Change Canada for July, there is a bulls-eye of brown indicating that our region was the most below average in all of Southern Ontario. So maybe it wasn’t just our imagination.</p><p>The very dry month put the total for the year of 341.9 mm now even further below the average of 509.0 mm.</p><div class="separator" style="clear: both; text-align: center;"><a href="http://weather.uwaterloo.ca/download/historical/2022/202207_precip_anomaly.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="375" data-original-width="468" height="375" src="http://weather.uwaterloo.ca/download/historical/2022/202207_precip_anomaly.png" width="468" /></a></div><br /><p>Summary for July 2022:</p><p>Maximum Temperature 33.6°C<br />Minimum Temperature 7.1°C<br />Average Daily High Temperature 27.8°C (Long term average 26.0°C)<br />Average Daily Low Temperature 12.1°C (Long term average 14.0°C)<br />Total Precipitation 18.7 mm (Long term average 98.6 mm)</p><div>(Long term averages based on 1981-2010 data for the Waterloo-Wellington Airport)</div><p><br /></p><div><div class="separator" style="clear: both; text-align: center;"><div class="separator" style="clear: both;"><br /></div><div class="separator" style="clear: both;"><br /></div><br /><div class="separator" style="clear: both;"><br /></div></div></div>Frankhttp://www.blogger.com/profile/05902865763952811195noreply@blogger.com1tag:blogger.com,1999:blog-1896989304324119352.post-24510032906658574552022-07-10T14:02:00.008-04:002022-07-10T14:02:55.860-04:00June 2022 Summary<p><b>A dry June with average temperature</b> </p><p>**Note that the UW Weather Station’s main controller stopped working at the end of January, we have received a replacement and are currently setting it up, the data for this month’s summary comes from readings taken at the Waterloo Regional Airport**</p><p> With 6 days above 30°C compared to the average of only 2 and a high of 34.1°C on the 21st, it might be assumed that it was a much hotter than average month.
