We'll get one more "mild" day today and THEN the cold snap begins.
An upper ridge is rippling across the province.  Temperatures in southern Alta will get above zero & here in the Capital Region, we'll be around -10 later today.
The snow looks like it'll stay to the north (and likely won't amount to much more than 2-5cm for the Grande Praire/Peace River/Slave Lake/Lac La Biche/Fort McMurray regions)
In the Edmonton area, a chance of flurries tonight & Friday morning.  But, no significant accumulation if we get anything at all.

Through the weekend, there's a chance Edmonton could get 2-5cm of snow Saturday night into Sunday.
But by early next week...skies start to clear & we should be partly cloudy for Christmas Eve & mainly sunny on Christmas Day.

The coldest air will start to retreat to the east by Christmas Day.  So, western Alberta will be a good 5 to 10 degrees warmer than eastern Alberta by Tuesday of next week.

Speaking of Christmas Day, it looks like Edmonton is in for the COLDEST "Christmas Stretch" in over 30 years!
Daytime highs are projected to be:  
-21 Monday
-19 Tuesday
-17 Wednesday

That's the coldest set of Christmas Eve, Day & Boxing Day highs since 1971 (when it was -28 on Christmas Day).
In Monday's WxBlog, I discussed the warming we usually see around Christmas in Edmonton.  That's not going to be the case THIS year.
