Division of seasons on the Prairies with storm, rain and snow threats

Parts of the eastern Prairies got an early taste of severe weather season Saturday, with reports of hail and even funnel cloud sightings east of Regina as the storms moved through. Sunday features another thunderstorm threat, though weaker in nature. Meanwhile, southern Alberta will take a step back into wintry weather as snow is expected for the foothills. Flurries could even fall along the QE2, reaching places such as Red Deer and Calgary into Monday morning. More on what to expect in the days ahead, below.

SUNDAY: STORM RISK LESSENS, RETURN OF SNOW

Mother's Day will see the thunderstorm chance return to the southern Prairies. However, the risk is generally non-severe in nature, but we could see pockets of stronger storms with small hail and gusty winds bringing beneficial rain to southern Alberta and Saskatchewan.

So be mindful if you’re in the regions facing the threat while out and about celebrating Mother’s Day. The storm threat will span the southern region from Calgary to Winnipeg.

However, in true springtime fashion, things will change in a hurry across the southern half of Alberta. Colder temperatures will crash into the province Sunday night into Monday. The thunderstorm threat will quickly give way to a chance for snow in the foothills.

The QE2 from Red Deer to Calgary will have a chance to see flurries, but accumulations will be limited, if any, due to melting on contact with the surface. However, there is a chance of 3-5 cm falling by Monday morning, enough to create slick driving and a tricky commute.

Meanwhile, heavy rain will continue over northern Saskatchewan Sunday, with another 10-20 mm expected in some areas. It will begin to taper off through the day, with areas near the N.W.T. border easing off in the evening.

LOOK AHEAD: WARMING UP MID-WEEK, BUT THREAT OF MORE RAIN FOR FLOOD-PLAGUED MANITOBA

Much cooler temperatures will bathe the western Prairies heading into early next week. Temperatures will trend back toward seasonal by the middle and end of the week. Meanwhile, eastern regions will see temperatures hovering around seasonal for the week.

Unfortunately, more unsettled weather is on tap for the eastern Prairies this week. We’re on the lookout for yet another Colorado low bringing widespread rain to parts of Manitoba and eastern Saskatchewan on Monday.

Through Monday, this next slug of precipitation could bring 20-30 mm of rainfall to areas still recovering from flooding and waterlogged fields, all while missing areas where the rain is desperately needed.

In the last 30 days, Calgary has seen less than 40 per cent of its normal precipitation, while on the other side of the Prairies, Winnipeg is 200 per cent over its normal amounts.

Beyond, forecasters are also watching the potential for yet another high-impact storm late next week and weekend. There is some chance for this system to take a more westerly track. If that verifies, then it would bring rain to areas that really need it.
