There was some rain in southwestern Manitoba over the weekend as a frontal boundary stalled out. Rainfall amounts, however, were not all that significant. Another boundary is moving through today. There is a slight chance of showers in the region but the best potential is off to our east. Expect a high today of 22. It'll be partly cloudy tonight with a low of 10.

Ridge of high pressure gains control tomorrow. We'll see plenty of sun, a light wind, and a high of 23. Tomorrow night features a mostly clear sky and a low of 10. Another sunny, warm day in store for us on Wednesday. The forecast high is 25 degrees. The beautiful weather continues on Thursday with more sun and a high of 25 again.

Models are in agreement showing a strong low pressure system and frontal boundary moving through at the end of the week. Early signals show the potential for an organized thunderstorm event in southwestern Manitoba as well as North Dakota on Friday. There appears to be plenty of moisture to work with. It's still a ways off but severe weather is possibility on Friday and/or Friday night.

A tough call regarding what to expect on the weekend. Some forecast models are showing a strong upper low hanging back in central Saskatchewan. We'll see a mix of sun and cloud on both Saturday and Sunday with highs in the mid twenties expected. There may be a shower around, at times, this weekend.

 

The image below shows an example of cumulus clouds. These clouds can take on multiple personalities as they signal fair weather but, under the right conditions, can grow into thunderstorms. That may be the case just east of the region later today. A more widespread threat of storms comes on Friday.
