According to the weather agency, the system which is developing over Texas, will then track north over the Great Lakes and hit the region on Wednesday.
They say ”latest indications suggest snow, mixed with ice pellets, will move into the regions Wednesday morning” and the ”there is a chance that the snow and ice pellets could change over to freezing rain or even some rain on Wednesday night.
The mixed precipitation is then expected to change back to all snow by Thursday morning as colder air begins to work its way in from the north.
Predicted snowfall amounts vary, with just 2 cm expected over southern areas and 15 to 20 cm possible in more northerly regions.
Environment Canada says travelling conditions are expected to deteriorate quickly after the snow arrives on Wednesday and are urging people to avoid travel if possible.
