March 7th-8th Snowstorm - Part 2
As predicted, the second round of snow arrived in the city around 3 pm. The winds picked up and snowfall rate intensified. Computer models are showing that the storm will linger around the area overnight tonight and will swiftly shift eastward by tomorrow morning.
So I went outside to battle the elements and in its simplistic form, a true Canadian winter storm. I did my snowfall measurements and took the average. Here are the summary for today as of 1700 EST:
Davis Vantage Pro2
Max temperature: -5.1 deg. C (1158 EST)
Min temperature: -6.6 deg. C (1658 EST)
High wind gust: 40.2 km/h (1555 EST)
Low SLP: 998.31 mb (1657 EST)
Fresh snowfall (average): 20.0 cm but it’s still snowing so this is not the final measurement
Snow on the ground (average): 27.6 cm
The all-time 24 hour record in the city:

There is still a lot of steam in this low pressure system. I’ll provide another update soon including the historical record for the month of March here at Toronto East York weather station.
