Colorado Low will bring mostly rain this weekend – PembinaValleyOnline.com


After seeing winter drag on well past its due date, with several significant snowfalls throughout April, the news that another low in Colorado would affect the province this weekend had many thinking: ” When will this end?”

“There is good news today as it looks like it will be a predominantly heavy rain event for areas south of the Trans Canada Highway,” Chris Sumner, a CMOS-accredited meteorologist, explained Saturday morning. “As the path of this system has continued to evolve over the past few days, the area within the rain zone has grown to the west. That said, as you get closer to the Saskatchewan border, and then north towards Highway Number One and Highway 16, significant snowfall is still expected for those regions.”

A rain warning continues for all of southern Manitoba, including the Melita, Boissevain, Killarney, Pilot Mound, Manitou, Morden, Carman, Winkler, Altona, Emerson, Morris, Vita and Steinbach areas. A winter storm warning has been issued for the Souris and Virden regions. 1-2 inches of rain is possible in areas under the rain warning, potentially more for places that see thunderstorms on Saturday afternoon. At this point, the highest rainfall totals are expected east of the Red River, with totals falling slightly as you move west. The Virden and Souris region, and areas to the north, are in line for a wintry mix of rain on Saturday and then potentially 8 to 16 inches of snow on Sunday night.

“After thunderstorms hit the Red River Valley and southeastern regions on Friday afternoon, there is a chance of more thunder later today,” he said. “Unstable, warm, moist air moving north from the Gulf of Mexico will provide the necessary ingredients, with a warm front moving north from North Dakota as a trigger for potential thunderstorm development.”

An inland flood warning, issued by Manitoba Transportation and Infrastructure, remains in effect for most of southern Manitoba.

“We still expect some snowfall in the Red River Valley and southeastern Manitoba, but it will be limited, potentially up to 5cm at most by Sunday night, most likely at the low end of that range, with a lot of melting early in the change. Sumner said. “Rain will continue through Sunday morning, and as cooler air moves down as winds shift to the northeast, precipitation will change to snowfall by midday. We could see a bit of a muddy mess on the roads in the afternoon and evening, but that will depend on how much snow we see and it doesn’t melt, plus it will only be part of the travel story on Sunday.”

Winds will pick up Saturday afternoon, gusting to 60 km/h across the region. Gust conditions will continue into Sunday, potentially reaching 80 km/h in many parts of southern Manitoba.

“We expect those winds to line up with the snowfall time frame, so that means snow and reduced visibility may be a concern later on Sunday,” Sumner added. “As we look at general travel conditions in southern Manitoba, the most difficult conditions are expected along the Saskatchewan border and north into Parkland and Interlake.”

Impacts from this latest Colorado minimum will subside Sunday night as the system continues to move east toward northwestern Ontario. A cloudy and very cold day, by the end of April, will kick off on Monday of next week.

“Those strong northerly winds will give way to a very cold air mass for this time of year, as high pressure from the Arctic slides south and push temperatures 15 to 20 degrees below average for this time of year. year from Sunday to Tuesday. Daytime highs during those three days will be in the zero to -5 range. For the last week of April, normal highs are around 14 or 15 degrees.”
