An early morning round of showers and thunderstorms had PembinaValleyOnline Rainwatchers checking their gauges before noon Thursday.

“An area of showers and thunderstorms that pushed out of central North Dakota then moved northeasterly across Southern Manitoba, and brought another round of accumulating rainfall to the region,” explained CMOS Accredited Weathercaster Chris Sumner. “Most of the precipitation fell between 4am and 10am Thursday, with it out of the region before noon.”

A nearly 24-hour period of light to moderate rainfall Wednesday afternoon to Thursday evening brought the first significant, accumulating precipitation to the region in two to three weeks, depending on what point you are referencing.

A weak disturbance sliding through Southern Manitoba Sunday morning and into the afternoon led to many PembinaValleyOnline Rainwatchers seeing something in their gauges by last night.

A very slow moving area of thunderstorms has brought excessive precipitation to the Altona, Gretna and Rosenfeld regions with streets in downtown Altona overflowing the curbs.

"The isolated thunderstorm cells popped up before 8am north, west and east of Morris, and since then have very slowly been tracking southward," noted CMOS Accredited Weathercaster Chris Sumner. "The storms were moving extremely slowly, and because they were moisture packed, that gave them the opportunity to unload considerable precipitation as they dragged southward."

Several Severe Thunderstorm Watches and Warnings were issued for the southern Red River Valley Saturday afternoon and early evening as scattered storms rolled across the region.

“A trough of low pressure sinking southward through the area was the trigger for the development,” noted CMOS Accredited Weathercaster Chris Sumner. “Some locations saw a couple rounds of showers and thunderstorms, and as is typical with this type of convective development, those places that had a storm roll overhead saw a significant amount of rainfall.”

Monday morning started with cracks of thunder, flashes of lightning and gusty winds as thunderstorms move through the area.

In almost a carbon copy repeat of what happened Saturday afternoon and evening, another round of pop-up thunderstorms rumbled over parts of the Pembina and Red River Valleys Sunday afternoon and evening.

In typical Summer fashion, the Pembina Valley region saw scattered late afternoon and early evening thunderstorms Saturday. According to CMOS Accredited Weathercaster Chris Sumner, some rural areas may have received significant amounts.

Two rounds of heavy rain and thunderstorms Canada Day wrapped up a long weekend book-ended by precipitation.

The first of two upper level lows to impact Southern Manitoba over the next few days produced a grey, damp and cooler than average Friday to kick off Canada Day long weekend.
