It's shaping up to be another unsettled week of weather across Alberta and in the Edmonton region.

No sustained sunshine or warm temperatures, although we'll start out the work week with daytime highs in the low 20s today and Tuesday.

Showers and/or thunderstorm are possible across most of central and north-central Alberta later today with the potential for strong/potentially damaging wind gusts.

Closer to the upper low in northeast Alberta, there's a risk of hail and cold-core funnel clouds.

East-central Alberta has the potential for funnel clouds and potentially a landspout tornado late Monday.

The upper low moves off into central Saskatchewan on Tuesday, but a deep area of low pressure moves in from the west and sets the stage for another afternoon of showers/thunderstorms.

The potential for severe thunderstorms looks to be even higher in central and southern Alberta on Tuesday.

THEN...as the surface low-pressure system stalls out in east-central Alberta on Wednesday, there's the potential for heavy and steady rain through the day in central and north-central Alberta.

Models are indicating the potential for 50+ mm of rain for areas near (and including) Edmonton.

Looking further ahead, Friday evening has the potential for another round of powerful thunderstorms in north-central Alberta.
