We'll get a bit of everything this weekend.  Well...everything but snow.
Edmonton should get into the low 20s again today & Saturday.
The pattern changes late Saturday/early Sunday.

The Upper Ridge starts to collapse and we'll have a cold front sweeping across the province.
I still think that front should push through the Capital Region early Sunday morning.
So...the strongest wind & best chance of rain is forecast for Sunday morning.
By Sunday afternoon...sunny breaks, wind slowly easing & cooler.

Temperatures will drop 5-10 degree behind that cold front.
We go from the low 20s Saturday to the low-to-mid teens Sunday.
Those "cooler" temperatures are close to average and should stick around through Mon/Tue.

Elsewhere around the province:
NW - Low 20s & Increasing cloud Saturday.
Chance of showers late Saturday night/Sunday morning.
Cooling to highs in the 10-15 range Sun/Mon

NE - Near 20 & Partly cloudy Saturday.
Chance of showers & windy Sunday - high near 10.
Clearing & mid-teens Monday.

S-Ctl - Near 20 & Mix of sun & cloud Saturday.
Partly cloudy Sunday/Monday with highs in the mid-teens.
