This week’s forecast has prompted Environment Canada to issued a “Special Weather Statement.”
A broad low pressure system will affect the province of Quebec this week bringing unseasonably mild temperatures, rain, and a rapid drop in temperatures.
At first, the weather will be mild and rainy for Tuesday and Wednesday.
This will give favourable conditions for the rapid melting of the existing snow cover.
Water ponding may be significant in some places.
The high on Tuesday is expected to be 12 degrees Celsius, which would break the previous record of 10.9 degrees Celsius set in 2000.
The high on Wednesday is forecast to hit 14 degrees Celsius, which would break the previous record of 8.3 degrees Celsius in 2017.
A vigorous cold front will then move through Western, Southern and Central Quebec between Wednesday afternoon and Thursday morning. As it passes, rain will change to snow, and strong westerly winds will develop.
Montreal could see 15 to 20 millimetres of rain, which would melt any existing snow and could cause ponding on the roadways.
Finally, temperatures will drop sharply, rapidly freezing water on the ground. Roads could quickly become slippery, making travel difficult.
