Environment Canada has issued a weather warning for the Montreal area, predicting rapidly dropping temperatures and heavy flurries.
The weather agency says snow accumulations could reach up to five centimetres, but likely not in the Montreal region.
The warning is in effect for Châteauguay-La Prairie, Laval, Longueuil and Montreal.
A cold front is expected to sweep across Southern and Central Quebec Thursday evening into overnight.
Environment Canada spokesperson René Héroux says that while Montrealers may wake up to a "dust of snow" on the ground, it's the cold they have to worry about.
Temperatures could drop as low as -9 C overnight Thursday.
Meanwhile residents in the Abitibi-Témiscamingue are bracing for a full-on snowstorm.
The Lac-Témiscamingue school board announced Thursday morning that its primary and secondary schools as well as its adult learning centres are all closed.
The district's school bus routes are also cancelled.
