Southern Ontario: Fall Weather Hazards Outlook for Sunday, November 28, 2021

Forecast Discussion

A system currently bringing accumulating snowfall to parts of Southwestern Ontario during the evening on Saturday is expected to merge with a system over Northern Ontario as it drops southward across Southern Ontario. This will spread light to moderate steady snowfall through areas east of Lake Huron and into the Golden Horseshoe during the morning on Sunday and continuing into the afternoon.

Accumulation won’t be overly significant with general amounts ranging from 5-10cm (although a few pockets could pick up slightly higher amounts if we see some lake enhancement) by the end of Sunday when the snow is expected to taper off. Regardless, this will likely be the largest snowfall much of the GTA and surrounding regions outside of the snowbelt have seen this season thus far. If you’re travelling on Sunday, leave plenty of time to get to your destination as roads will likely be slushy or snow-covered.
