Rainy & mild day for Montreal

We remain on the mild side of a slow moving cold front this morning with temperatures near 6C in Montreal. Low pressure continues to move northeast well to the north of Montreal with the cold front expected to clear the region today. Ahead of it we had about 6mm of rain overnight on L'Ile Perrot but radar is showing more steady rain to our southwest lifting towards eastern Ontario and southern Quebec. It should be a rainy day with temperatures fairly steady across southern Quebec between 5 and 8C. Expect about another 10mm or so in Montreal but much more along the US border where rainfall warnings are in effect. Those locations including Sherbrooke could see an additional 25-35mm of rain. Further to our south in Vermont and east central New York heavy rain is also forecast with a flood watch posted for those locations. The combination of up to 1 inch of rain, snow melt and moving river ice could lead to sharp rises on area waterways. Another point to take note of for all regions is to stay off and away from river ice which has begun to melt here is the south and has become very unstable.

Storm next week?
Cooler air will move into the region tonight behind the front with lows dropping to -2C and any rain tapering off to a brief period of wet snow. The balance of the week looks unsettled and much cooler with flurries possible. A weak clipper system may bring a few centimetres of snow for Saturday. Another storm is poised to affect the region early next week. This far out amounts and type of precipitation is too difficult to pinpoint, but it may be snow for some of us.
