After some parts of the Pembina Valley received between 50 and nearly 70mm of rainfall early Friday morning, according to our PembinaValleyOnline Rainwatchers, a few locations received a second round of precipitation Friday evening.
"Shortly after 7pm, and in a matter of 15 to 20 minutes, a large thunderstorm cell developed west of Morden, extending from the Crystal City area northeast toward Manitou," explained CMOS Accredited Weathercaster Chris Sumner. "Shortly after that, a second cell quickly developed south of Winkler near the U.S. border, extending northeastward toward Morris. Both of these storms moved very slowly in an east-southeast direction over the course of the next 90 minutes to two hours, keeping their respective intensity for much of the time, before weakening and crossing the U.S. border."
Sumner added the areas that received rain were very localized, giving the example of how Rosenfeld received nearly 18mm, but Altona, only 10 kilometers south, saw a little bit of drizzle and essentially no measurable precipitation.

Comfortable weekend forecast
"Behind a cold front that moved through Friday, cooler and more comfortable conditions are on tap for the weekend," said Sumner. "Slightly below seasonal daytime highs are expected Saturday and Sunday, landing between 23 and 25 degrees. The humidity will be much less, as well. A shift to northerly winds will also bring a return of hazy and smoky conditions to the region, as wildfire smoke is pushed southward."
Averages for this point in July are 26 degrees daytime and 13 degrees overnight.
Sumner noted the next chance for rain appears to be Sunday night into Monday when a trough of low pressure originating in Alberta swings southeastward across the Prairies and possibly leads to shower and thunderstorm development in Southern Manitoba.
