After flirting with hot and humid the last couple of days, we are now officially into that with Environment Canada issuing Heat Warnings for all of Southern Manitoba. Today and Friday look like they will be the most humid days of the Summer, so far, with it feeling like nearly 40 at times as daytime highs push to 31 to 33 degrees.

Multiple rounds of thunderstorms, some severe, rolled through parts of the Pembina and Red River Valleys beginning late Canada Day evening.

Starting Wednesday, Southern Manitoba entered a much more active weather pattern than in recent weeks. That from CMOS Accredited Weathercaster Chris Sumner.

A couple rounds of precipitation arrived across the Pembina and Red River Valleys over the weekend.

"The first came mid to late Saturday afternoon when the cold front associated with a low pressure system centred over northern Manitoba swept through the region," explained CMOS Accredited Weathercaster Chris Sumner. "A line of storms from the Interlake south into North Dakota developed along that front. There have been a couple of reports of extremely gusty winds as the front moved from west to east."

A very much welcomed round of showers wound through the region late Monday morning into mid-afternoon. The last accumulating rainfall across much of the area came May 20th, and that was only a few millimeters in most cases.

Forest fire smoke is expected to return to the region today, so Environment Canada has issued a Special Air Quality Statement for the Red River Valley and Southeastern Manitoba. Included are places like Morden, Carman, Winkler, Altona, Emerson, Winnipeg, Dominion City, Steinbach and Vita.

Coming out of May Long weekend it was a similar weather theme to the start of it back on Friday; wet and cool.

"We had a very similar weather set-up early morning Tuesday to Tuesday afternoon when a slow-moving upper-level low pushing northward out of the Dakotas brought another round of rainfall to the region," said CMOS Accredited Weathercaster Chris Sumner. "If you happened to take a look at the RADAR imagery Monday morning, it looked almost like a carbon copy of the system we had move through Thursday night into Friday."

For farmers, gardeners and firefighters attacking the wildfires in eastern Manitoba the much needed rain over the last two days was very much welcomed, even if it did mean a soggy start to May Long weekend.

Much needed rainfall has arrived across Southern Manitoba, and for some locations the last 24 hours is the first accumulating precipitation (more than trace to a millimeter) in three to four weeks.

More daytime high records were set Tuesday during the final day of the unusual heat wave which has baked Southern Manitoba since Sunday. 

"With Environment Canada ending the Heat Warnings for the region, yesterday's record setters mark an end to three consecutive days of extremely hot, dry and windy conditions," noted CMOS Accredited Weathercaster Chris Sumner. "When we look back on this stretch of three days, it will be historical for not only just how warm it was, but also the fact it stayed that warm for that long this early in the season."
