Today will be perfectly sunny, with perhaps a few clouds at times in the afternoon. Expect highs around 28°C. Tomorrow will be very similar with mainly sunny skies, and highs around 26 or 27°C. Wednesday could be one of the hotter days this week, as a breezy southeast wind pumps in an extra boost of warmth humidity. Our first 30°C of the year will be possible Wednesday.
There may be some showers and storms in southern Manitoba late Wednesday, into Thursday. It does not look like a major event so far, however I will still keep an eye out. Thursday and Friday both look warm as well.
Things get a lot more interesting on the weekend. Many models are hinting at a very strong low pressure system moving into Saskatchewan and the Interlake Sunday. With this, a cold front will slice southwards into the very warm and humid air mass. GFS is showing some significant shear, instability, LI's and a decent llj. All of this raises concern for a severe thunderstorm outbreak Saturday and Sunday. The SPC (Storm Prediction Center) in the US already has our areas in a day 6 and day 7 risk. To issue a risk of severe storms this far in advance is rare, especially for our area. This system will need to be monitored very carefully, as a tornado outbreak will be possible on both sides of the border if the current model solutions verify.
