Weather Warning for Montreal
On the coldest morning of the season to date (-8C here in Montreal), Environment Canada has issued a Weather Warning for southern Quebec from the Ontario border south and east to the Townships. Low pressure is lifting north from Texas into the Ohio Valley today and will pass just south of Quebec across New York State on Wednesday. Clouds will thicken up later today and the precipitation associated with this storm will spread across eastern Ontario after midnight and into Montreal during the overnight period tonight. Snow mixed with freezing rain will be the type expected here in the city with 5-10cm forecast. That amount falls well under the heavy snow warning criteria, but due to the fact it is the first snow of the season and the onset occurring during the morning commute, the warning was posted to alert the public. Up to 15cm (6 inches) may fall in the Eastern Townships and the Green Mountains.
The National Weather Service has Winter Weather Advisories posted for northern New York and Vermont. Tomorrow is a big travel day across North America, and you can expect delays in the east. Those not being affected by snow and freezing rain can expect gusty winds and heavy rain from Boston to New York. Today will be calm region wide with sunny skies and cold temperatures around 0C in Montreal. Temperatures will drop to -2C in the snow overnight and remain near 0C on Wednesday. Winds are also expected to be a factor in southern Quebec and the St. Lawrence Valley, gusting between 30 and 50km/h out of the northeast on Wednesday. Skies should clear Thursday and it will turn very mild once again.
