Monday saw rainfall in the Portage la Prairie area turn the roads to slippery and wet conditions.
Across the region, many towns and cities saw well into the double digits in millimeters of rainfall.
“Based on Environment Canada historical data, it’s likely many locations in the Red River Valley and Southeastern Manitoba will set single day rainfall totals for November 19th,” said CMOS Accredited Weathercaster Chris Sumner. “Yes, it's happened periodically in the past to have a shower roll through this late in the season, but it is exceptionally rare to have the necessary weather conditions at this point in the year to produce the amount of rainfall we received.”

According to Sumner, Tuesday’s precipitation came courtesy of a moisture packed Texas low which pushed northward out of the United States, and essentially merged with another area of low pressure that originated from the Pacific coast that arrived in Southeast Saskatchewan and Southern Manitoba at pretty much the same time.
“The initial forecasts of the Red River Valley and Southeastern Manitoba seeing rainfall for most of the day held true, with the snow/rain line landing pretty much along the Manitoba escarpment,” he added. “Areas west of that saw wet snow and snow develop late Tuesday morning as colder air was pulled into the west side of the system the soonest. It wasn’t until late Tuesday afternoon and early evening that regions further east saw the first snowflakes from this system as it slowly progressed eastward.”
