Seasonal Weather turning unsettled for the weekend

 Much of southern Manitoba has been experiencing a calm second half of the week, thanks to high pressure settling over our area. A possibly unsettled weather pattern is on the way for the weekend. Find out where and when showers and thunderstorms can be expected, and what to expect temperature wise. 

Friday Temperature Outlook (Above) : Expect a fairly nice day, with a few clouds during the day time. A low pressure system will be sitting over Saskatchewan during the day on Friday, ahead of it temperatures are expected to soar into the mid to high 20’s. Areas further north from highway 1 north into the inter lakes can expect high temperatures to be in the high teens to low 20’s. 

Friday Night: This is when it gets interesting a low pressure system is expected to move into southern sections of Manitoba, ahead of it a broad area of CAPE from 1,500 to 2,000J/Kg will present itself over southwestern sections of Manitoba by early evening. Showers and thunderstorms are likely to develop in western Manitoba before spreading east into the red river valley regions in the mid evening. With lower CAPE in place the risk for severe weather is lower but still present. However the only model right now that is an outlier appears to be the HRRR which is suggesting a dangerous wind event in a line of severe thunderstorms that may target southwestern Manitoba into the Red River Valley or moving southeast into North Dakota. This is something that is over 24 hours away from, and we’ll know more about model consensus tomorrow morning or afternoon. Temperatures on Friday night appear to drop into the mid to high teens for a majority of the region, except low teens in the interlakes. 

Saturday (Above): Expect thunderstorms or showers to clear the region with another resurgence of showers or weak thunderstorms in the afternoon. A trough of low pressure will also be east of Manitoba by the afternoon so a northwesterly flow will be aloft. Temperatures in the inter lakes are expected to be in the high teens in the inter lakes region, with highs in the low to mid 20’s in the southern half of Manitoba. 

Saturday Night: Clearing conditions are likely with mostly cloudy to partly cloudy skies expected, temperatures on Saturday night will drop into the low teens to mid teens. 

Sunday: Some of the nicest weather is likely on this day with high pressure building in. Temperatures slightly below average with most places seeing a slight chance for showers. Weather wise mainly only a mix of sun and cloud is likely. Temperatures will rise into the high teens and low 20’s. 

Sunday Night: More of the same is expected, some increasing clouds are possible during the evening to overnight with a chance of showers and thunderstorms in southwestern Manitoba as another frontal system approaches. It’s way too early to tell if these will be severe. We will know more on Sunday. Temperatures will drop into the low to mid teens, with the exception of the southern red river valley seeing lows in the 10C mark. 

First half of the week: Warmer and milder weather is likely for the first half of the week, hotter and more humid conditions are possible as dewpoints rise into the mid to high teens to low 20’s. All on the northern end of a ridge and a trough will slide through that , with an increasing risk of severe weather.
