Mild Thursday expected for Montreal

Temperatures have nudged above the freezing mark here on L'Ile Perrot so the threat of any freezing rain will be diminishing here in the St. Lawrence Valley. Only light rain showers are forecast today as a messy low pressure area moves from the Great Lakes north to near Hudson Bay. This is the same system that brought the blizzard to western Canada and the northern plains. Freezing rain warnings are in effect for the Ottawa Valley and points north of Montreal but so far any precipitation has been light. The warm front should clear Montreal this morning with temperatures surging to well above normal highs of 8C (48F). A trailing cold front will cross the region this evening with a round of showers gradually changing to light snow and ending overnight as temperatures drop rapidly to 1C and remain there on Friday. The weekend at this time looks much colder but dry with some much needed sunshine.

By Monday another developing storm over the Ohio Valley will begin to move towards southern Quebec. Snow or a wintry mix look likely for Monday with perhaps enough snow to shovel. We will have to monitor that storm as the event draws closer with the path and type of precipitation still uncertain.
