Squalls, clipper system threaten additional snow after historic GTA storm

A historic winter storm moving across North America broke several records in southern Ontario on Sunday after walloping the most populous region in the country with intense snows.

Toronto-Pearson Airport saw 46 cm of snow as of 6:00 a.m. Monday, breaking the record for the most snow ever recorded at the station in a single day. Records at the airport began in 1938.
Sunday’s all-time record beats out the previous snowiest day on Feb. 25, 1965, which saw 39.9 cm of snow pile up at the airport.
The Greater Toronto Area’s very heavy accumulations resulted from a band of lake-effect snow that developed within the larger snowstorm itself. This enhancement greatly intensified snowfall rates across the region, allowing for steep totals in just a few hours.
Despite the storm moving off toward Atlantic Canada, significant travel issues and widespread closures will continue through Monday. Road closures, lane restrictions, flight cancellations, and school closures will be commonplace to start the new workweek.
Clipper system threatens additional snowfall amounts into Tuesday
Lake-effect snow develops in the wake of the historic winter storm, impacting the snowbelt regions through they day on Monday. A clipper system from the Prairies will track across southern Ontario on Tuesday, as well, with light and blowing snow expected throughout the day.
Tuesday afternoon, frontal snow squalls could bring heavier snowfall and potential whiteouts in parts of southern Ontario. Additional lake-effect snow will follow, with snowbelt areas potentially receiving 15-25 cm over the upcoming days.
Temperatures will also remain very cold. Daytime high temperatures in the city of Toronto may not rise above -10°C for the next seven days, which is an unusual feat for this part of the country.
