A Winter Weather Travel Advisory is in effect for southern Quebec for 5 to 15cm of snow Monday afternoon and evening. Travel will be impacted as a result of snow covered roads and reduced visibility for the evening commute Monday across eastern Ontario, southern Quebec into northern New York. Dropping temperatures during the evening hours will likely result in very icy roads.

The various groundhogs were split in their forecast across Canada on Sunday, with Shubenacadie Sam in Nova Scotia, seeing his shadow and predicting 6 more weeks of winter. Meanwhile Wiarton Willie in Ontario did not see his shadow, predicting and early Spring. Here in Quebec, Fred la marmotte saw his shadow, sadly agreeing with Sam.

From what I am seeing this coming week and beyond in the weather models, I would lean towards Sam's prediction. We have a very active weather week ahead once again, with plenty of precipitation, as well as a roller coaster ride for temperatures.

After a frigid Sunday that featured morning lows as cold as -22C in Montreal, temperatures will moderate through the overnight hours and into Monday as a warm front lifts across the region. Highs on Monday will be very close to the freezing point, if not above for some locations. The front will produce some light snow Sunday night, with less than 5cm forecast. Late Monday our winter weather advisory goes into effect as a strong cold front brings moderate snow and gusty winds. Between 5 and 15cm is possible over southern Quebec into the early morning hours Tuesday.

At this time Tuesday and Wednesday look breezy and cold, but dry as arctic high pressure settles into Quebec. On Thursday, a stronger low pressure system will pass through the St. Lawrence Valley, with warming temperatures and mixed precipitation. Another 5 to 10cm of snow is possible. A stronger storm may take aim at the region next weekend, but there is still plenty of uncertainty with the forecast track. Stay tuned!

Either way, winter will persist for the foreseeable future across the Montreal region.
