Hot Today, Gone Tomorrow

Temperatures in the low 30’s combined with dewpoints in the low 20’s will make it feel like 40 degrees today.

A slow-moving low pressure system associated with a sharp, digging upper trough over the west coast is bringing southerly winds to the RRV under strong southwesterlies aloft.

850mb temperatures are climbing into the mid-20’s ahead of these features, which when combined with a southerly 40G60 km/h wind and sunny skies, will result in the temperatures soaring into the low 30’s today across much of Southern Manitoba, with temperatures reaching to near 35°C just on our side of the international border.  The strong winds will also last into the evening, keeping the air well mixed, which means we can expect very warm temperatures (> 25°C) probably past midnight.

Tomorrow we will recover a few degrees from our overnight low and then cool in the afternoon with the passage of a cold front.  There is a chance of showers and thunderstorms tomorrow associated with the cold front, however timing of the passage will be critical in determining who will or won’t get any precipitation/storms.  Currently, models are suggesting that the cold front precipitation will fire up just east of Winnipeg, so areas like Dugald & Steinback would see afternoon showers.  The GEM has been under-doing the lift associated with this entire system, however, and positioning will be crucial, so it’s too early to say much, other than tomorrow will be cooler, cloudier, and a chance of showers and thunderstorms will hang around the RRV from late morning to the evening hours.
