Today will be one word: spectacular! The sun will stay with us all day as temperatures reach high 20's. I'm anticipating a high around 28 or 29°C in Winnipeg. Winds will be brisk out of the south, but given the heat it will be refreshing. I don't anticipate any storm activity around the city today.
Tomorrow will be the hottest day of this warm spell as temperatures soar into the low 30's (assuming lots of sunshine). I'm anticipating a high between 31 and 33°C in Winnipeg, which would be the first 30°C day in May since 2007 when we hit a record 31.3°C on May 9. If we manage to reach 32°C, it would be the first time to do so in May since 1995. Note that the old daily record high tomorrow is 32.7°C in 1980. Will be interesting to see how warm we get...

Humidity will also be on the increase with dewpoints in the mid teens expected tomorrow. This could give humidex values in the mid 30's, noticeable but not extreme. A thunderstorm is possible throughout the day, especially early morning and again in the evening. Lack of shear and lack of large scale triggers may hinder severe potential, but a severe storm can't be ruled out across southern Manitoba nonetheless.
Sunday looks unsettled as a trough and cold front sweep through. Showers and thunderstorms are likely throughout the day as a result. Severe storms are possible but not hugely likely.
As of now, it appears we really have turned the corner. Generally normal to above normal conditions are expected to persist for the foreseeable future. However, rain and storms will be possible during the work week next week... details to come as the events draw closer.
