Yo-yo Weather Trends Continue – Snow or freezing rain in the Northwestern Ontario Forecast

Weather UpdateTHUNDER BAY – Our regions yo-yo weather trends are continuing again as we head into the week. Environment Canada is stating, “A low pressure system centred over Central Manitoba this morning Will track across Far Northern Ontario today and over northern Quebec tonight. Precipitation ahead of this low will spread over Northwestern Ontario this afternoon and evening, and move over Northeastern Ontario overnight. Temperatures are forecast to be Near or just above freezing, so the precipitation will fall as wet snow or rain.

“Total snow amounts could reach the 5 to 10 cm range, with the higher amounts from Red Lake to Armstrong to Little Abitibi.

“However, the main concern with this system is the cold air that lies behind the associated cold front. This cold front will cross Northwestern Ontario late this afternoon and this evening, and Northeastern Ontario Tuesday.

“Much colder air behind the front Means that temperatures will drop sharply from just above zero to well below freezing in a matter of hours. If precipitation occurs just before or at the time of the temperature drop, this is a
favourable situation for a flash freeze event. Untreated surfaces like roads and sidewalks will quickly become slippery making for hazardous travelling conditions.

“Flash freeze warnings may be issued as this event becomes more certain.”
