It’s shaping up to be a slightly cooler-than-average Halloween in Edmonton. But, it could end up being the chilliest Halloween in over a decade.
Temperatures will get to 3 or 4 C for an afternoon high and the 30-year average high is 5.2 C.
In the past decade, almost every Oct. 31 has been warmer than that long-term average.
In fact, the 10-year average high for Oct. 31 is 6.4 C and the last time Edmonton had an afternoon high below 5 C on Oct. 31 was in 2017.
Daytime highs for Oct 31
- 2023: 7 C
- 2022: 8 C
- 2021: 6 C
- 2020: 6 C
- 2019: 5 C
- 2018: 8 C
- 2017: 4 C
- 2016: 5 C
- 2015: 10 C
- 2014: 5 C
You have to go all the way back to 2012 to find the last time Halloween had a daytime high below 0 C.
It was -7 C on Oct. 31, 2012.
Earlier this week, it was looking like we might be closer to 0 C for an afternoon high, but the cooldown doesn’t look like it’ll be THAT dramatic.
We were at 8 C on Wednesday afternoon and only slipped a few degrees below 0 C this morning.
So, even though we won’t get a whole lot of sun today…I think we should get to 3 or 4 C later today.
Early-evening temperatures will hover around the freezing mark.
Friday and Saturday should be slightly cooler. It think we’ll be in the 1 or 2 C range for afternoon highs with morning lows in the -5 to -10 C range.
AND…I’m adding in a slight chance of some flurries or light snow for late in the day Saturday.
There’s a low-pressure system that’ll push across southern Alberta and some light snow is expected to develop on the northern edge of that system.
I think it’s unlikely that we’ll see any accumulating snow, but a few flurries are possible.
Areas closer to Slave Lake have a much better chance at seeing some light snow late Saturday and then the Cold Lake/Lac La Biche regions could get some snow on Sunday.
We should get back to the 5 or 6 C range for Sunday/Monday in Edmonton and then next week continues to trend warmer.
Daytime highs will likely be in the 7 to 11 C range for Wednesda-Friday of next week.
