Beautiful, above seasonal weather continues

Much of southern Manitoba is seeing above seasonal temperatures thanks to a large area of low pressure bringing in a southerly to southwesterly flow, along with it, it’ll bring calm weather will make for a fairly nice weekend. Unfortunately some unsettled weather is possible, read on to find out where and when and what to expect. 







Good chance at seeing highs in the high 20’s and near or slightly above 30C on Sunday in the white circled area. There is a chance elsewhere but it’s less evident or probable as it’s only the RRV/SE on the NAM model I’m using. 

Saturday: Sunny skies are expected for Saturday, temperatures will rise into the mid to high 20’s (24-27C) the warmer temperatures will be in the parklands,with more moderate temperatures in the rest of the region. Saturday night:  there may be some more cloud on Saturday night as the warm front passes through. A few showers are possible in southern Manitoba overnight , a few rumbles of thunder are also possible but because of capping no organized storms are expected. Temperatures will drop into the mid to high teens, (14-17C) closer to our normal day time highs, oddly. 

Sunday: Will be one of the warmest days we will probably see this season, and probably not again until next year. A cold front will likely cross through the red river valley and the eastern half of Manitoba by afternoon, despite this we will still have calm weather conditions with a majority of the unstable weather occurring in NW Ontario. There is a solid chance at seeing our daytime high temperatures soar into the mid to high 20’s with some areas seeing 30C (25-31C). The best areas for seeing the 30C mark include the Red River valley, Winnipeg and eastern Manitoba. Winnipeg definitely has a chance at seeing 30C on Sunday. 

Sunday Night: An approaching trough of low pressure will sink south ahead of it it’ll allow for a batch of heavier cloud cover with showers and some rumbles of thunder to move into our area, mainly from North Dakota late overnight into the morning period. Temperatures will drop into the low to mid teens (12 to 15C). 

First half of the week: Showers and embedded thunderstorms will occur for the first half of the day and last into the early evening. Severe weather is not expected however. Much cooler weather is anticipated as a northwesterly flow takes over, temperatures will change and drop well into the low to mid teens for daytime highs (11 to 15C). The coldest air appears to sit in the western half of Manitoba where a northwesterly flow will be present. Milder weather is likely for Tuesday with calmer weather conditions expected thanks to a building area of high pressure, even warmer weather possible on Wednesday as the high pressure moves off into Ontario bringing a southerly flow back to our area. I’m seeing a chance at us seeing the 20-25C range again .
