In short :

- Up to 15 cm of snow in places;
- Difficult road conditions on the South Shore.
A rainy entrance
The system, which had been monitored for several days, arrived in southwestern Quebec overnight from Saturday to Sunday. Coming from Colorado and preceded by a warm front, it will initially discharge its precipitation in the form of rain.
The sectors located on the south shore of the river up to the Eastern Townships will be the most affected by liquid precipitation. Some may also be entitled to episodes of freezing rain. All this water will represent a danger in the morning, when the descent of the mercury will transform it into ice.
One morning under the snowflakes
This drop in temperature will also affect precipitation which will turn to snow. For one of the rare times since the start of the season, the north shore of the river will receive few accumulations. Even in the Lower North Shore, the accumulations will not exceed five centimeters. On the south shore of the river, Montreal might receive up to fifteen centimeters of snow, just like the Estrie region.
Potentially dangerous road conditions
This mixture of precipitation might make it difficult to travel around and south of the St. Lawrence River. One of the main risks will be the newly formed ice lying under the thin blanket of new snow. Sunday morning, you should be particularly careful on the South Shore at highways 10, 15 and 20.
Motorists should also be vigilant in the followingnoon. Rain transformed into ice might affect the electrical network in places. Snowfall should nevertheless recede further east of the province, which will improve road conditions in the Montreal metropolis.
