Well, at least we had a couple of days without rain before another round of accumulating precipitation rolled across the Pembina and Red River Valleys late Sunday afternoon and evening.

"A low pressure system moving across the Dakotas pushed thunderstorms northward into Southern Manitoba," explained CMOS Accredited Weathercaster Chris Sumner. "The system was moisture filled as a southwesterly flow had been pumping the region full of instability and precipitable moisture all day."

Most areas saw a couple rounds of showers or thunderstorms, with a significant area of rainfall developing which, at one point, covered an area well into the Interlake to just south of the U.S. border, tracking northeastward as it moved eventually east of Lake Winnipeg.

According to Sumner, the active weather pattern will continue this week as it looks likely June will begin much like May ended with rainfall chances throughout a good portion of the week.

"Weak surface high pressure will keep things dry on Monday, but lingering cloud cover from yesterday's system will lead to a mix of sun and cloud for much of the day," he said. "We're expecting seasonal daytime highs between 23 and 25, before we take a turn to much wetter and somewhat cooler temperatures for Tuesday and Wednesday."

A low pressure system coming out of the Canadian Rockies will move across the southern Prairies, and will set the stage for more accumulating rainfall from early Tuesday morning through Wednesday night. Highs both days are expected to  be slightly below average between 18 and 21.

"Similar to what we've seen previously over the last couple weeks, this low will take its time crossing the region, and rather than continue moving eastward, is expected to take a turn northward meaning its impacts will linger longer than you would normally expect with a traditional west to east moving system."

What does that all add up to? In short, more moisture.

"Again, similar to what we've seen recently, there's the expectation there will be heavier bands of moisture within the overall system, and those areas which see those will see relatively higher totals," he said. "At this point, the general expectation is 10 to 25mm of rain is likely for most places between Tuesday morning and Wednesday night."

For the back half of the week, starting Thursday, there are signs upper level ridging and surface high pressure will bring a return to drier and sunnier conditions alongside seasonal to slightly above average temperatures.
