Prairie forecast: Potential to turn cool and wet

For this forecast period we are starting off with a large area of high pressure over Ontario and an equally large area of low pressure over the Yukon. The clockwise flow around the Ontario high, combined with the counterclockwise flow around the Yukon low, is creating a widespread southerly flow across the Prairies. This should lead to one more day of warm temperatures across the western Prairies and a couple more days over the eastern half.




Prairie forecast: Unsettled weather ahead

For this forecast period we start, once again, with no strong systems impacting the Prairies. But, as we head into the weekend a strong area of low pressure is forecasted to develop over the western U.S. This low will impact our region over the weekend, but how and where is a little uncertain.



Prairie forecast: Where did the summer heat go?

Looking at the big picture we start this forecast period with a generally zonal flow across the Prairies as Arctic high pressure slides across the far northern Prairies and weak low pressure moves by to the south. This will bring sunny to partly cloudy skies and near to slightly below-average temperatures.



Prairie forecast: Summer pattern making forecast difficult

We start this forecast period off with an area of low pressure over far northern Manitoba that is slowly moving off into Hudson Bay. To the west, an area of low pressure is developing over the Yukon which is helping to develop a weak ridge of high pressure over Alberta. Over southern Saskatchewan and Manitoba weak high pressure is in place.
