Snowfall WARNINGs for Edmonton & surrounding areas.  Winter Storm WARNINGs in the mountains.
As you can see on the attached graphic, the snow starts in southern & western Alberta today.
But, in the Capital Region...it's just cloudy for most of the day.
The snow moves in tonight & continues to fall heavily through the day Thursday.
By midday Friday, it should taper off in the Edmonton area.
Eastern Alberta will continue to see snow through to Friday evening.

It's important to remember that the snow totals on the attached map are estimates.
However, it's starting to look more & more likely that Edmonton will end up with around 20cm of snow by midday Friday.
In general, less snow is expected to the NE & heavier snow is anticipated over western Alberta.
Marmot Basin & other high elevation spots could get 50-60cm of snow.

The AMOUNT of snow will only be part of the story.
Wind & a blast of arctic air will be aggravating factors over the next few days.
Blowing snow & significantly reduced visibility will be a problem in all areas seeing snow tonight & Thursday.
AND...with temperatures dropping to the -20 range, Wind Chill will be near -30 in many areas late Thursday & through Friday morning.

Once the snow moves out, the wind will ease & skies will clear for the weekend.
But, the cold air settles in and actual temperatures drop into the -30 range (without the wind chill! ) Saturday & Sunday morning.

Looking LONG RANGE:
Warmer air should return to the Capital Region by the middle-to-end of next week.
Daytime highs are expected to be near -20 this weekend, but closer to 0 by Thu/Fri next week.
