Closures are racking up across parts of southern Ontario, as another round of powerful snow squalls hit the traditional snowbelt regions. Snow squall warnings remain in effect through Wednesday.
“Travel is expected to be hazardous due to reduced visibility in some locations. Rapidly accumulating snow could make travel difficult over some locations. Road closures are possible,” warned Environment and Climate Change Canada (ECCC) in the snow squall warning issued for the London area.

An additional 5-15+ cm could fall throughout the day on Wednesday, adding to the already hefty totals that have accumulated since Tuesday. If snow squalls become stationary over one area, locally heavier amounts are possible.
The snow squalls are expected to weaken later Wednesday night.
Bands of lake-effect snow persist into next week
After a very cold week, temperatures will rebound to near seasonal for Friday and the weekend. Widespread light snow will develop across the region late Friday and into Friday night, as moisture from the storm tracking across the southern U.S. will stream north and interact with the dynamics associated with the low pressure system tracking across northern Ontario.

Saturday will be partly sunny with bands of lake-effect snow hitting areas southeast of Lake Huron and Georgian Bay. Bands of lake-effect snow will also develop late Monday, and continue through Tuesday and into Wednesday for the same areas.
While no major storms are in sight, as we get deeper into the second half of the month, the pattern is expected to become more active as it will be more conducive to Colorado and Texas Lows, which can tap into moisture from the Gulf of Mexico.
