November 2010 Summary

Again with the hot temperatures and average precipitation

November kept the streak going for 2010 with an overall temperature that was a degree hotter than average. We have now seen above average temperatures for each of the 11 months of the year.

There was a regular hot streak from the 8th to the 14th and then a crazy 25 hours around the 22nd when it never went below 10 °C. On the graphs you can really see the difference in the daily cycle of temperature between the sunny/dry first half of the month and the cloudy/wet second half.

So after that incredibly dry first half of November, the second half made up for it getting us into the average range for the month. The total precipitation for the month was 72.7 mm with almost half of that coming on two wet days (16.8 on the 16th and 17.4 on the 30th).

We are now at 842.9 mm of precipitation for the year, a little above the average for this time which is 830.3 mm. It also looks likely that for the second year in row we will have an overall average year for precipitation.


Summary for November 2010:
Maximum Temperature 16.3 °C
Minimum Temperature -8.9 °C
Average Daily High Temperature 8.3 °C (Long term average 5.9 °C)
Average Daily Low Temperature -1.9 °C (Long term average -1.6 °C)
Total Precipitation 72.7 mm (Long term average 82.3 mm)

(Long term averages based on 1971-2000 data for the Waterloo Wellington Airport)

Was the average low really -1.9 (and not 1.9)? If so, that's really remarkable, that the average high would be 2.4 degrees above the airport normal while the average low was 0.6 below the airport normal. Even if it was actually 1.9 (and 2.3 degrees above the airport normal), it would still continue the trend of lows being lower relative to the airport normal than highs in the winter-ish as opposed to summer-ish months (assuming I haven't confused myself about what that trend was--I have confused myself a lot in trying to construct this sentence).

Any idea how much snow fell in November?

I can confirm that the average daily low temperature was indeed -1.9, it is not uncommon for there to be a large difference in the anomaly for the average high and low temperatures.

Whoops, I should have mentioned that there was only 1 cm of snow during November.

Note to Frank: Small printing mistake in last sentence. Reads, "the second year in row", is missing the word, "a". Should read, "the second year in a row." You may erase this note if you wish.

Hey Frank, I enjoyed reading your November 2010 Summary, but I think you should have mentioned that we received only one centimeter of snow in November, as compared with a normal amount of 14 centimeters, like you said in the front page news article in the Tue. Dec. 7 Waterloo Region Record newspaper. I know you mentioned in your Dec. 5 comment on your blog, that we got 1 cm. of snow in Nov. Well, the one centimeter November snowfall is great news to me, because I hate the snow! Now that General Motors is back in business, let's get this Greenhouse Effect back on track. No more snow for Canada.
