The extreme southwest corner of the province could be whalloped by a very dangerous thunderstorms late this afternoon and into this evening, but the worst of it will miss Brandon.
Environment Canada issued a severe thunderstorm watch this morning, noting that their forecasters have been tracking a slow-moving disturbance over Montana that's expected to feed moist, unstable air to the southern prairies.
Strong thunderstorms are expected to develop over Montana and North Dakota and spread northward late this afternoon and this evening. Because these storms will be moving slowly, there could be localized downpours of 50–75 mm in just a couple of hours in some spots.
The storms could also bring strong winds, large hail and flooding rain. Overnight, the storms should then push north and eastward into the Interlake and the southern Red River valley.
Brandon, meanwhile, will get the fringe of the storm around midnight, with about 5 mm of rain expected tonight, and then more tomorrow.
Before that, though, today should be an alright day. Despite mainly cloudy skies and a 30 km/h easterly wind, the high should hit 23ºC and the UV Index in the sun will be 7, which is high.
After a low overnight of 14ºC, storms will continue through the day tomorrow, with 10–20 mm additional rain and winds gusting from 40–60 km/h. Storms will clear up late in the afternoon, and a few patches of sun will poke out, but even more storms may develop into the evening. Tomorrow's high will be 20ºC.
Showers are expected to continue Friday, with a high of 21ºC, followed by a mix of sun and cloud on Saturday, which will see a high of 25ºC.
Sunday will start a string of sunny days, with a high of 24ºC to finish the weekend.
Into next week, Monday and Tuesday should be sunny as well, with highs around 25–26ºC.
The normal high for this time of year is 23ºC; the normal low is 11ºC.
The hottest it's ever been on this date was in 1995, when it was 32.5ºC. The coldest ever was in 2004, when it was 2.2ºC.
