Warmer with a Chance for Thunderstorms

(Weather Information provided in part by Brad from A Weather Moment and by Mike the Author)

A weak trough moving across SW Manitoba today will push into the Red River Valley this evening, producing some scattered showers or thunderstorms. Thing's look to clear out quickly, and we will be getting temperatures in the mid to high 20's for the weekend.

Forecasted rainfall from the GEM-GLB Model, from 00Z friday to 12Z saturday
We will have a little bit more of an unsettled day today as we see a weak surface trough feature move through our area in the Red River Valley this afternoon. Temperatures will climb to to over the 20C mark this afternoon before showers or thunderstorms develop over sections of Southwest Manitoba and push eastwards into the Red River Valley. According to Brad "Dynamics begin to fall apart as the afternoon progresses, and any showers or thunderstorms will struggle to survive in an increasingly disorganized environment." It looks like the best chance of seeing some rain potential will be through the Western Red River Valley, with chances diminishing east of the Red River. By the time the trough sets up shop in the whiteshell, the threat of Precipitation will likely be over.
Saturday will be a gorgeous day as we see sunshine dominate across Southern Manitoba and daytime highs will climb to around 25C. Things will turn a little bit more unsettled overnight on Saturday as an area of rain and storms blossom's over Southern Saskatchewan and heads our way. The exact location of the rain and storms is still uncertain, however best indications are that we will see a cloudy day in the Red River Valley with the bulk of the rain passing north of the City. areas likely in the interlake area will receive rainfall, with only a small chance for showers or storms for Winnipeg and South. I will keep an eye on this system as the weekend progresses.
