The prairies are known to have more than their fair share of wild weather shifts, a reality that looks on the verge of being on full display this coming weekend based on the current Environment and Climate Change Canada forecast for Brandon.
As of the time of this posting, the forecast high for the city on Saturday according to ECCC is a seasonally-balmy zero degrees. By Sunday a polar flow is expected to bring a significant shift and a high of just minus 16. Sunday’s overnight low is then forecast as minus 27. When factoring in the effects of wind chill, that temperature overnight Sunday and into wakeup on Monday is expected to feel like anywhere from -38 to -40 based on currently forecast temperature and wind.
A -40 wind chill value is significant since it is the threshold for Environment and Climate Change Canada issuing an Extreme Cold Warning, though risks associated with frostbite and hypothermia remain a particular concern even should values not quite reach that mark.
The deep freeze is expected to remain in place into next week with daytime highs of -14, -18 and -18 respectively on Monday, Tuesday and Wednesday.
The normal high temp for this time of the year is approximately minus eight. Record temperatures for Sunday through Tuesday look to be safe, with the lowest recorded amount on each respective day being into the minus 30s.
A return to more seasonal values is expected later next week with Thursday seen as topping out at -9. As always it is recommended checking the most-recent forecast for most current information.
Overall, based on a winter forecast released last week much of Canada including the majority of Manitoba are expected to see above-normal temperatures through February.
