We have a few showers moving through north-central Alberta this morning that’ll quickly push through the Edmonton region, but should be gone by late this morning.

Skies will clear for the afternoon and we’ll get into the mid 20s for the last time in a while.

A cool spell starts Wednesday and continues into the weekend. Daytime highs will be in the mid to upper teens for Wednesday-Friday. I think we’ll probably get back into the low 20s for Saturday/Sunday, but we could be anywhere between 19 and 23 C for afternoon highs.

As for precipitation, there’s a good chance of some showers or thunderstorms in the Edmonton region this evening and overnight (although the main risk overnight will be for areas further south near Red Deer/Coronation).

Some steadier periods of rain will move through central and north-central Alberta on Wednesday and there may be some embedded thunderstorms.

Rainfall totals will vary widely, but roughly 10-20 mm looks likely.

For Edmonton and area, the rain will be in the area all day and may stick around right through Wednesday evening.

Thursday and most of Friday should be dry. But, we’ll probably have some more showers later in the day Friday (either late afternoon or in the evening).

The longer-range temperature outlook has us back in the mid 20s for a few days early next week.

But, after today we may not get above 25 C more than twice before the end of next week.
