A severe thunderstorm threat returns to Southern Manitoba today as very warm and humid conditions persist in the region for one final day before a cold front pushes cooler and drier air into the region. The passage of the cold front will not be an end to the unsettled weather, though, as a couple more days of showers or thunderstorms will occur with a large upper-level low passing over the region.
Today brings a notable severe weather threat to southern Manitoba with a slight risk of severe thunderstorms developing over southwestern Manitoba and a moderate risk in the Red River Valley eastwards through the SE corner of the province.1 The thunderstorms will develop mid-day and push eastwards with the cold front through the remainder of the afternoon. It is most likely that the thunderstorms develop over southwest Manitoba first, and then push towards into the Red River Valley this evening. Stay aware of any watches or warnings issued by Environment Canada.
Otherwise, this mornings cloud cover will break up a bit to produce mixed skies and the relatively small amount of sunshine will push the daytime highs to around 26°C. With very humid air in place, it will be a fairly uncomfortable day, feeling more like the low- to mid-thirties. After the thunderstorms move through this evening, we’ll head to a low near 16°C with breezy southerly winds.
Tomorrow will likely bring some sun first thing in the morning, but more clouds will move in with a good chance of more shower or thunderstorm activity in the afternoon. At this point severe thunderstorms aren’t expected, but we’ll keep an eye on things to see if anything changes. Winds will be pick up to be gusty out of the north near 40km/h. Expect a high near 23°C and a low near 14°C with a continued chance for showers overnight.
Wednesday will be a cool and cloudy day with a good chance of more rain. The daytime high will only be around 20°C and winds will continue gusty out of the northwest, although not quite as strong as Tuesday. The shower activity will taper off in the evening as temperatures head to a low near 14°C.
The latter half of the week is looking like a return to seasonal temperatures and a chance of actually drying out a little bit.
Winnipeg’s seasonal daytime high is currently 26°C while the seasonal overnight low is 13°C.
