Two Alberta Clippers are heading East bringing snow to Southern Ontario. The GTA could see up to 10 cm with more for the Bruce Peninsula area with lake enhanced snow.
The Tuesday morning commute could be slow due to snowy roads and visibility reduced by falling snow. Commuters should consider giving themselves more time.
The Ottawa area will see snow starting Tuesday morning with the system moving out of Southern Ontario by the evening and overnight period.
Cold Temperatures on the Way
Once the Clippers have moved out of Southern Ontario, the first of two Arctic air masses will descend. A relatively moist Arctic air mass will cause temperatures to drop beginning Tuesday evening.
By Thursday, the drier, Continental Arctic air mass will move in pushing temperatures down even further. Friday could be the coldest day with morning temperatures in the - 20's for most of Southern Ontario.
During periods of extreme cold, time outside should be limited as frostbite in exposed skin can occur rapidly.
