The MétéoMédia – Heavy spring snowfall threatens slippery travel in some regions of Quebec
Wednesday, April 21, 2021, 5:01 p.m. – Mother Nature has not yet finished delivering snowfall to Quebec, as a strong American depression threatens parts of the province with 15 to 30 cm of snow on Wednesday.
Parts of Quebec experienced a snowstorm on Wednesday, resulting from the same system affecting southern Ontario as it moves south of the Great Lakes. While Montreal will not be too badly affected, with around 5-10cm expected, areas south of the St.Lawrence River – those closest to the low pressure system could see accumulations of 15-30cm of snow by the time the system is moving. Snow warnings and special weather reports are in effect. For more on the timeline and impacts, see below.
WEDNESDAY: SNOW INTENSIFIES THROUGHOUT THE DAY, ‘MAJOR SLOWS DOWN’ FOR SOME
The first of the precipitation reached southern Quebec on Wednesday morning, with snow intensifying as the day progressed. In the early evening, there were still special weather reports in effect for the eastern part of the province, including Quebec City.
Accumulations will be greatest south of the St. Lawrence River, where 15 to 30 cm are possible. North of the river, in Estrie, 10-20 cm is possible. Areas along the St. Lawrence will be right on the demarcation line with 5-10cm of snow, while Montreal is expected to see around 5-10cm. Between 3 and 5 cm are expected for communities northwest of Montreal.
The snow will cease for Montreal on Wednesday night, but will persist Thursday for the northeastern sectors of the province.
A LOOK AHEAD: MORE GENERATED WEATHER BY THE END OF WEEKEND
Abundant sunshine and a spectacular rebound in temperatures are expected for Friday. Temperatures could reach the lowest teenagers in Montreal, but will be cooler in the east. Partly sunny conditions and daytime highs in mid-teens are expected in southern Quebec on Saturday.
The next system will move very slowly eastward, with rain developing over southern Quebec on Sunday, which may persist until Monday. Colder than seasonal temperatures are expected behind the system early next week.
A few days of much warmer weather are possible for the middle of next week, but forecasters are also watching for the potential of another period of colder weather to return on the weekend.
Stay tuned to MÃ©tÃ©oMÃ©dia as we continue to monitor the progress of the storm and its impacts on Quebec.
