A Return to Some Stormier Weather

(Information Provided by Brad from A Weather Moment)

Parts of Southern Manitoba will be under an increasing risk for thunderstorms as the week progresses. Heat and some humidity will slowly build into the region, as a trough begins to build over the Rocky Mountains before it tracks eastwards across the Prairie region later this week.

 We will warmer temperatures today as warmer air pushes in behind a warm front that passed through the region overnight. Daytime temperatures should be near the 25C mark through most areas of the RRV. By this afternoon a weak frontal system will be along the international border with a trough extending to the NW towards a low pressure system tracking into Western Manitoba. Showers and possible thunderstorms will develop over SW Manitoba this afternoon and slowly track eastwards into the RRV. According to Brad ``It will mainly be regions through the northern Red River Valley that face the risk for showers or thunderstorms (Portage la Prairie, Winnipeg, Selkirk; as seen in the image above)` The showers and thunderstorms will lift north into the interlake overnight while temperatures drop to the low to mid teens in most of the South.

For Thursday a north to south band of showers with the embedded thunderstorm will likely form over the Red River Valley or the Whiteshell in the afternoon. This line will likely move eastwards and intensify into a band of thunderstorms. The potential exists for 50mm in rainfall accumulations, I will keep a close eye on this as things develop.

Friday looks like it will be a nice day with comfortable humidity and daytime temperatures near 20C. Brad notes that A large MCS is forecast to develop on Friday night in North Dakota, bringing the chance for a stormy and rainy Saturday.
