Windy much colder week ahead

The heavy rain that fell in southern Quebec since Thursday, has produced plenty of standing water on area roads. (ValleyWX)
Strong low pressure is moving into the Gulf of St. Lawrence this morning after providing the region with another dose of heavy rain on Saturday. This storm was the second in as many days to impact Montreal, eastern Ontario and southern Quebec. Heavy, wind driven rain occurred late Saturday, adding to the already impressive three day storm totals. More rain fell in Montreal in 24 hours than in the entire month of September (31.2mm). I measured 90.4mm as of 7am this morning here on L'Ile Perrot. Trudeau Airport recorded 88.6mm, St Anicet 94mm, Cornwall, Ontario 91mm, Kemptville, Ontario 79.7mm and Ottawa 55mm. The rain changed to wet snow across portions of upstate New York, Vermont and along the Quebec, New Hampshire border overnight. Reports this morning indicate anywhere between 5 and 20cm (2-8 inches) of wet snow. Snow was also reported Sunday morning in Sherbrooke and Quebec City.

The weather is a raw and windy this morning in Montreal, with west winds gusting over 70km/h. Those strong winds will be with us for the next 24 hours. Expect unsettled weather this week, with some sunny breaks, but frequent clouds. There is the possibility of scattered showers or even some flurries at times. Temperatures will be below normal, with highs near 8C (47F) and lows around 2C (36F). By the end of the upcoming week, another storm system will bring us more rain.
