Daytime highs will be a lot closer to records than the seasonal averages again today.
However, it's not expected to be AS warm as Wednesday in the Capital Region and across much of the rest of Alberta.
That said, most of Central and Northern Alberta will end up in the 5-10 degree range this afternoon.

We have some scattered showers & wet flurries in NW Alberta this morning.  That precipitation will push into the High Level region.
In the Edmonton area, a few scattered showers are possible later this afternoon.

The Upper Ridge will be collapsing today and we'll start to see a cooling trend develop on Friday.
Cloudy with flurries/light snow in Northern Alberta on Friday.  Some spots could get 1-5cm of snow by the end of the day Friday.
That snow should stay north of Edmonton.  But, a system pushing in from the SW over the weekend likely WILL give snow to the Capital Region Sunday.
Snow is expected to start falling across southern and western Alberta on Saturday afternoon and will push towards Edmonton Saturday evening.
At this point, it looks like we could get 3-8cm of snow in the Capital Region on Sunday.
That system is still a few days away and things could change (so...stay tuned to the forecast).
But, if things play out as expected...we'll go from +16 Wednesday to shovelling snow Sunday/Monday.

Cooler (but not COLD) air sticks around through next week.
Daytime highs will likely be in the 0 to -5 range in Edmonton.
