Saskatchewan Severe Storm Outbreak; Quiet in the Red River Valley

We’ll move into a slightly quieter pattern after a low pressure disturbance moves through central Manitoba. This system is currently moving through western Saskatchewan and will produce a dangerous outbreak of severe thunderstorms along the Highway 11 corridor between Saskatoon and Regina today with torrential rain, hail possibly bigger than baseballs and a very real threat for an isolated tornado or two. The severe weather threat will be mostly confined to Saskatchewan today unlike Saturday when the substantial severe storm threat was expected to push into SW Manitoba.

Today & Tonight

Monday

30°C
Clearing then mainly sunny.
Monday Night

20°C
Cloudy periods with a chance of showers.

We’ll see a beautiful day toaday in the Red River Valley with sunny skies dominating after a few isolated showers move out of the area this morning. We’ll see temperatures climb to around 30°C this afternoon before some clouds move in in the evening ahead of the storms moving out of Saskatchewan. There will be a slight chance of showers tonight through the Red River Valley along the tail end of a thunderstorm complex that will be moving through the Interlake. As the low pushes across central Manitoba, the Red River Valley will move into the warm sector of this system, bringing much warmer, more humid air into the region. Thanks to this, we’ll see overnight lows quite a bit warmer than the past couple nights. We’ll eventually drop to around 20°C with noticable humidity.

Severe thunderstorms will move into western Manitoba this evening along a dryline pushing eastwards out of Saskatchewan. Storms are expected to stay well north of the Trans-Canada Highway, moving more through the Dauphin & Minnedosa areas then pushing eastwards into the Interlake overnight as an MCS capable of producing large hail and strong damaging winds. The storms will have trouble moving southwards thanks to a layer of dry air in place over the Red River Valley that will likely either kill or substantially weaken any weather that tries to push our way.

Tuesday & Wednesday

Tuesday

27°C / 15°C
Clearing then mainly sunny.
Wednesday

27°C / 15°C
Sunny with cloudy periods.

We’ll see more stable weather for Tuesday & Wednesday as a surface ridge begins working it’s way into the province. A fairly light northwesterly wind will kick in on Tuesday morning which will slowly push out much of the humidity in place over us making this feel quite a bit more comfortable outside. Wednesday will bring more sun than cloud with daytime highs pretty much the same as Tuesday. There will be a slight chance of light showers near the International Border through the period but no significant accumulations are expected.
