Friday, November 8th 2019, 8:30 pm - Travel conditions deteriorate in local intense squalls through Saturday, with eyes on a widespread snow threat that looms for southern Ontario Monday.
Dangerous snow squalls will continue across parts of Ontario through Saturday morning with as much as 30 cm possible under the most intense bands by Sunday morning. Though the squalls do die down by end of day Saturday, attention then turns to a potential system that could bring a more widespread snow later on Monday. More on where the travel remains the worst through the start of the weekend, plus a look at the arctic air and significant system that could snarl the start of the new workweek, below.

WATCH: TRACKING SHIFTING SQUALLS THROUGH SATURDAY
Snow squalls blasted parts of southern Ontario on Friday, with 27 cm reported in London through the morning. While winds have shifted, lake-effect streamers will be with us again on Saturday.
Presently, the areas most likely to see significant lake-effect snow Saturday into the early afternoon are the Bruce Peninsula and east of Georgian Bay. Amounts in the latter area, as well as parts of the Nickel Belt and east of Lake Superior, will be enhanced somewhat by system snow from a low moving through the region this weekend.
Lake Erie and Ontario may also produce a few bands, mainly through Saturday morning, and likeliest in the Niagara and Hamilton region. As winds continue to shift Saturday afternoon, these bands may also drift through the GTA and along the 401 corridor north of Lake Ontario, though accumulations will be limited.
