Wednesday: Wednesday will start off with sunny skies a area of high pressure will be sitting over central portions of Manitoba. Temperatures for the region will start off fairly cold but will warm throughout the day.

Temperatures during the afternoon will rise into the high minus single digits (-5 to -9C) for portions of extreme southern sections of Manitoba near the American border reaching the central red river valley including Winnipeg. Areas north of the transcanada highway will see temperatures in the low minus double digits (-10 to -15C). Windchills however will still be in the high minus double digits (-15 to -20C).

Temperatures are expected to be in the low minus double digits in the south western portion of Manitoba (-10 to -15C) and in the mid minus double digits (-15 to -18C) in the south eastern portion of Manitoba. Note that the further you go temperatures will drop substantially with temperatures in the high minus double digits in Interlakes and parklands regions (-18 to -22C). Wind chills for the region from Central Manitoba in between the northern and southern sections of the lakes, to the American border will see windchill values in the mid to high -20s. (-20 to -31C). Winnipeg: Cloudy. Low -14C, windchill -25C. Brandon: Cloudy. Low -12C, windchill-26C.

Temperatures for the region will soar into the mid to high minus single digits (-5 to -10C). Windchill’s however will be in the mid minus double digits. (-10 to -15C). Winnipeg: Cloudy, 30% chance of flurries in the afternoon . High -7C, windchill -14C. Brandon: Mostly Cloudy, 30% chance of flurries in the afternoon . High -8C, windchill-14C.
The weekend: Looks likely that an area of low pressure will be moving into the region bringing a chance for some snow, although nothing major. A stronger system will be bypassing the province impacting Minnesota and the high plain states where a blizzard looks likely. That won’t be hitting Manitoba however. Temperatures were also moderate as a westerly flow takes over during the weekend , with values returning to the mid to high minus single digits.
