Southern Manitoba will be under the influence of multiple low pressure systems over the weekend , on the northern edge of a ridge in the southern United States. As well this will be the main weather pattern over the coming days, temperatures will continue on the above normal trend.
(Above: A small Alberta clipper will move through the region on Sunday, giving about 1 to 5 or more cm of snow). A area of low pressure , will move into southern Manitoba during Saturday along with a warm front draped over areas of central and southern regions of the province. Cloudy skies are expected for the afternoon on Saturday, along with some sunny skies are possible in the southeastern sections of the province. Whereas by the parklands, there high temperatures for the region will be in the low to mid minus single digits between -1 and -8C. Winnipeg: Mostly cloudy, high -6C. Brandon: Mostly cloudy, High -3C.
Saturday Night: An arctic cold front will move south into northern North Dakota, behind it an area of high pressure will move into the regions of central Manitoba. Clear skies are expected. Along with it temperatures will drop drastically, there’s a good chance of seeing overnight lows in the low minus single digits to mid minus teens in the interlake regions with windchills in the minus 20’s (-7C to -15C.) Winnipeg: Clear, low temperature -8C, windchill minus 13C. Brandon: Clear, low temperature -3C windchill -9C.
Sunday: Another area of low pressure will slide along the international border into southern sections of Manitoba. Snow will begin on Sunday evening in the southwest section of Manitoba, moving east throughout the evening and overnight hours. Accumulations won’t go up much. On average once 1-7 cm of snow is expected, some areas in the Red River Valley and inter lakes could see up to 10cm. Temperatures will rise into the mid to low minus single digits (-1 to -5C). Snow will continue into the overnight period. Clearing skies are expected with temperatures dropping into the mid to low minus single digits (-5 to -10C).

First half of the week: Interesting week ahead, it appears the warmer than average temperature trend will continue at least into Wednesday, with warm temperatures in the low to mid minus single digits. Looking into the model data there is a chance for a winter storm sometime late Monday or early Tuesday. We at Manitoba weather centre will keep you updated on this unfolding situation.
