April 2015 Summary

A very average April for both temperature and precipitation

There were quite a few really warm days during the month, but these were offset by a cold spell during the last half of the month.  It was an average month for temperature as the overall temperature was just 0.1 degrees below the average and the first month of the year that wasn’t in the colder than average range.

It was also a pretty typical April for precipitation with a just few storms here and there.  The 77.0 mm we saw was a bit higher that the average of 74.5 mm, but still within the average range.

A close to average month for precipitation means that we didn’t really close the gap between what we have seen so far this year (198.7 mm) and that we would expect at this point in the year (264.4 mm).

I’m hoping it is now safe to call an end to the 2014-15 snowfall season, with April adding 3 cm, the total for the season was 127.5 cm.  This is a lot less than the average of 159.7 cm and the lowest total since 2011-12.  I would like to thank our snow measurement volunteers Melinda, Eric, Stephen, and Dave.

Summary for April 2015:
Maximum Temperature 21.1°C
Minimum Temperature -6.1°C
Average Daily High Temperature 11.8°C (Long term average 11.5°C)
Average Daily Low Temperature 0.4°C (Long term average 0.8°C)
