Weather nerdery for Edmonton Alberta, with side discussions of nearby rural stations, and other big Canadian cities.
We're back today with Edmonton's Winters - the Good, the Bad, and the Data (Part 2).
Let's talk snow!
(Our only snowfall measurement is at the airport, which is quite a bit colder than the city. But it's what we've got, so we'll use it)

This morning's Low of around 2.9°C will be very close to November 10th's warmest Low on record, at 3.3°C from way back in 1895.
Today is supposed to be pretty warm, but to get to the record High we would need to get way up to 17°C, from 2005.

The airport didn't measure any snowfall yesterday, so it looks like November 7th will probably be the official first snow of the winter.
That's pretty late. Recently 2021 got to the 14th, and 2011 to the 11th. But 2016 got snow on August 27th.

On Halloween Edmonton's average High is 5°C, and the average Low is -3.2°C.
But Halloween 1984 scared and scarred a generation of kids with a High of -17.7°C, and a Low of -23.7°C.
1991 & 2003 were also unusually cold, but nothing like that.
