Hey everyone we're gonna do a quick weather update for the weekend normally I would go into in depth information about our overall weather setup. This weekend looks to be one of those more unsettled setups got multiple days of rounds of thunderstorms that could impact a majority of southern Manitoba. Read on more below.
During the afternoon on Saturday a area of low pressure will sit over central Manitoba just north of Winnipeg, this area of low pressure looks to create an unstable air mass during the afternoon there will be a possibility or threat of strong thunderstorms some of which may be severe however we're not looking at a large severe threat comparative to other events that we've had. If we do get severe storms they will be marginal with hail only about 1 to two millimeters thickness and rainfall of 30 to forty millimeters, Environment Canada is suggesting that majority of these storms will remain subsevere however some may briefly approach or surpass severe limits. Temperatures on the day Saturday will be warm in the southeast with the majority of the SE seeing highs in the mid to high 20s there is a possibility that some localities may be a bit cooler especially in the southwest part of the province where showers and scattered thunderstorms are possible to develop during the afternoon and evening hours. If storms can hold off till later in the afternoon temperatures may reach the low to mid twenties in the southwest.
On the overnight into Sunday expects partly cloudy to mostly cloudy skies with the possibility of more clearing towards morning hours. Overnight temperatures on Saturday night will likely drop into the mid teens with areas Across the region dropping between 11 and 15 degrees Celsius. Cooler In the southwest.
Sunday will be a much calmer weather day compared to earlier this Weekend, I'm looking at high temperatures on a day Sunday rising into the mid 20s areas around the Manitoba Lakes however maybe a little bit cooler seeing temperatures in the upper teens. Unsettled weather will not be expected on the day of Sunday however odd pop up shower may occur. Heading into Sunday nights this is when there could be a threat for severe weather over southern Manitoba a complex of thunderstorms may likely develop in Saskatchewan and then drift E SE over the parklands into the Lake Manitoba region and then the Red River valley and Interlake regions overnight. We will wait on model runs to come out to verify this. The NAM model is suggesting this as well as the NAMNEST model. These thunderstorms may present a severe threat we will know more by Sunday afternoon. Temperatures will remain seasonal for a majority of the night with temperatures dropping into the mid teens.
The week ahead looks potentially active especially the day on Monday, A renewed threat for severe thunderstorms is possible during the afternoon and evening on Monday. A frontal system will move through southern Manitoba during the afternoon hours there is a possibility for increased levels of instability as humidity and heat move in from the United States this may be the hottest day of the week with temperatures rising into the upper 20s and humidity values in the upper 30s and possibly near 40C.
