Just three days after a series of Tornado Warnings had the region on alert, another round of severe weather rolled through the Pembina and Red River Valley Saturday evening.
“Severe Thunderstorm Watches were issued late Saturday afternoon, with Severe Thunderstorm Warnings issued not too long afterward for the Morden, Winkler, Plum Coulee and Altona areas, the same places which saw the Tornado Warnings Wednesday,” explained CMOS Accredited Weathercaster Chris Sumner. “Thankfully, this time around, only heavy rain and strong wind gusts were part of the mix. It was a relatively small line of storms that developed extending from the Morden region southwestward to Snowflake and into the United States.”
Sumner noted the storms packed quite a punch on the east side of the Red River, but quickly weakened as they past Altona, and crossed over into Letellier, Emerson and Dominion City area.
“By the time the system reached those more easterly areas, the storms were essentially non-severe in nature,” he said.

The rain will taper off Sunday morning, with Father’s Day afternoon looking at least partly sunny but windy, with westerly gusts up to 60 km/h possible.
“As this low pressure system continues to push northeastward toward Hudson Bay, those strong winds will develop,” noted Sumner. “Highs Sunday are expected to land between 21 and 23 degrees daytime, with sunshine and calmer conditions Monday. Highs tomorrow will again be around 21 to 23, and will be accompanied by a light northeasterly breeze.”
The break in the wet weather won’t last long, with another strong low pressure system expected to move northward through the Dakotas and Minnesota Monday night through Tuesday, giving most of Southern Manitoba another round of precipitation.
“It looks like we could see another 10 to 20mm of rainfall from that system,.” said Sumner. "After that, we should see drier conditions for Wednesday and Thursday, but as highs warm toward seasonal, and sunshine returns, daytime convection will more than likely put us in the position of daily shower and thunderstorm chances throughout much of the mid to late week period. There are also signs an additional system could be in the mix for Thursday and Friday that could bring even more rainfall to the region.”
Average daytime highs for mid June are around 25 degrees, with overnight lows around 12 degrees.
