Northern Ontario: Fall Weather Hazards Outlook for Monday, October 18, 2021

Forecast Discussion

UPDATE (Sun Night): Temperatures in the latest data are milder making the potential for flurries lower although it still can’t be ruled out. It will likely be very wet and melt on contact. We are holding with our initial map, but keep in mind that it likely won’t be as widespread.

Scattered showers will affect parts of Northeastern Ontario and up into Far Northern Ontario along Hudson Bay late Sunday with temperatures expected to drop to near the freezing mark early Monday morning. These colder temperatures could allow for the precipitation to transition over to some wet flurries particularly along the Quebec border. The risk for flurries will continue throughout the morning but should come to an end by the noon hour as the moisture moves out of the region. Very little accumulation is expected due to the warm group and earlier rainfall. At most, we can expect one or two wet slushy centimetres that will quickly melt later in the day.
