Seasonal weather will be in place over southern Manitoba as the last long weekend of the summer arrives. Conditions will be fairly dry except for a disturbance rolling through on Saturday night.

All in all it’s going to be a lovely weekend with most of the chances for precipitation outside of “plan-ruining” hours. Today we’ll see a chance for some morning showers – or perhaps even an isolated thunderstorm – as a cold front passes through the Red River Valley. Winds will shift to the north behind the front and temperatures will climb to around 22°C under increasingly sunny skies for the afternoon.

Tonight will be clear with a low of around 8°C.

Saturday will be a very pleasant day with mainly sunny skies and a high near 23°C. Winds will shift to southerly through the day, but remain relatively light at 20–30km/h. Some cloud will begin streaming into the Red River Valley ahead of an approaching low pressure system that will move through on Saturday night.

This system will be compact and intense with strong dynamics associated with it. Showers and thunderstorms will spread into the Red River Valley overnight on Saturday – likely not until late overnight. It’s unclear if much of a severe threat exists with these storms, although it does look like they could be fairly strong. Rainfall amounts will be dependent on the timing and intensity of convective activity, but in general it looks like 10–20mm of rain is likely, with isolated amounts approaching 50mm possible in worst-case scenarios.

The activity will continue into Sunday morning and clear out by mid-day. The rest of Sunday will be quite nice with clearing skies and temperatures climbing to around 22°C. Sunday night will be mainly clear with temperatures dipping near the 10°C mark.

A Beautiful Holiday Monday

For the upcoming holiday Monday, it looks like another pleasant, seasonal day with highs near 21 or 22°C and mainly sunny skies. The pattern looks to hold for much of the remainder of the week, where conditions look dry and the possibility of some warmer weather returns near week’s end.

Have a great weekend!
