Also of note, there is a slight threat of freezing rain over extreme southern Manitoba, south of Highway 1, Saturday, March 7 near midnight and Sunday, March 8, early in the morning.
 
Gusts to 50 km/h are expected behind the exiting low the evening of Sunday, March 8 in the Red River Valley south to the American border.
 
By the morning of Monday, March 9 heavy snow is forecast to be in northwestern Ontario, with only a few flurries lingering behind the system.
