Freezing rain warnings have been posted by Environment Canada for all of eastern Ontario and southern Quebec including Montreal. Low pressure, with an elongated warm front, will approach the Great Lakes early Tuesday and move down the St. Lawrence Valley on Wednesday. As with every other storm this winter, this system will be accompanied by a surge of warm air. Snow is forecast to start Tuesday morning in southern Ontario and spread into Montreal by mid-afternoon. The snow will mix with sleet, and eventually change to freezing rain. Accumulations of snow will range from 3 to 5cm from Montreal south to the US border. Expect 10 to 15cm north and east of the city towards Quebec City. A prolonged period of freezing rain is likely Tuesday night in Ottawa and Montreal. Winds are forecast to increase in southern Quebec, up to 50km/h Tuesday and 70km/h by Wednesday. The combination of ice on trees and wires and strong winds may produce some isolated power outages.

The temperature will be warming up on Tuesday, from -10C (14F), up to 0C by midnight. The high on Wednesday will be early in the day, around 2C (36F). Expect rain showers changing to flurries, with very strong winds. Colder air returns behind the storm for Thursday, with a low of -16C (4F) and a high of -5C (23F).

Expect very poor travel Tuesday and Wednesday across our entire region. Weather warnings extend into Ontario and across most of northern New England.
