Sunday, November 22nd 2020, 8:52 pm - The snowfall will likely impact travel on Monday morning, so motorists should plan ahead before venturing out on the roads.
The late-fall snowstorm that brought widespread impacts to southern Ontario on Sunday will bring another dash of snow early Monday. Drivers may find the roads challenging during the morning hours since freezing rain and ice pellets are possible along the shores of Lake Ontario and in eastern regions of the province. The unsettled trend will continue in Ontario as another low pressure system will track across the region on Tuesday evening, which will bring a mix of rain and snow. Details and timing, below.
- Snowfall lingers into Monday morning
- Slight warmup looks to take hold later on the week
MONDAY: SNOWFALL LINGERS IN THE MORNING HOURS
Snow will continue through the overnight hours in Ontario and many will wake up to hefty accumulations, particularly those in eastern regions of the province. Many regions saw between 15-20 cm of snow fall throughout Sunday.
The unsettled weather will continue on Monday morning. There is the risk of freezing rain and ice pellets along the shores of Lake Ontario and in areas extending from Kingston to Ottawa, which could complicate travel during the early morning hours. Ottawa and surrounding regions could see an additional 5-15 cm of snow throughout the day.
"Be prepared to adjust your driving with changing road conditions. Rapidly accumulating snow could make travel difficult over some locations. Visibility may be suddenly reduced at times in heavy snow," Environment Canada warns.
BEYOND: CHILLY START TO THE WEEK, POTENTIAL FOR MESSY WEATHER
The boundary between the warm and cold air will then press south of the region during the beginning of the week, and while Monday will feature a slight recovery in temperatures, Tuesday sees daytime highs not far above zero, and even below for a few communities in eastern and northeastern Ontario.
A somewhat disorganized system will track across the region Tuesday night into Wednesday with snow to the north and a rain-snow mix in the south, with all rain in southernmost areas. It is early to have confidence in snow totals, but this could bring 5-10 cm for Ottawa and much of eastern Ontario, as well as cottage country.
Another warmup looks to take hold for the second half of the week, though not as drastic as the one that will have preceded it the previous week.
