Another 30°C+ day will give way to stormier weather tonight as a cold front pushes across Southern Manitoba. We’ll see a slightly cooler weekend than the weather of late as we remain in the cooler air behind this system.

We’ll see temperatures climb into the low 30’s across Southern Manitoba again today as we remain under the influence of a pool of warm air entrenched over the Eastern Prairies. After some of this morning’s debris cloud from last night’s nocturnal convection clears out, here in Winnipeg we’ll climb to a high near 31 or 32°C, while areas to our south could reach as high as 33°C today.

Things will change promptly this evening as a cold front pushes across the province. Showers and thunderstorms will develop along the front in the early to mid-evening and continue to grow in coverage as the night progresses. This line of showers and thunderstorms will move through the Red River Valley overnight, bringing 5-15mm of rain to the region, the potential for some areas to see a bit over 1” total accumulation, and hopefully a good light show. These storms are not expected to be severe, and could potentially be one of the last night-time light shows we’ll get in 2012.

Tomorrow we’ll see a daytime high only around 24°C with a southwesterly wind at 20-30km/h. Sunday will reach about 25°C with lighter winds. Skies should be mostly sunny both days, with just an occasional cloudy patch here and there.

Temperatures are expected to climb back towards the 30°C mark through the first half of next week.
