Strong winds blast Quebec & Ontario after record warmth

There is so much to talk about this morning in the weather department as the seasons clash. Deep 978mb low pressure over the northern Great Lakes is the dividing line between early fall and winter weather. Montreal was on the warm side of the storm on Monday as strong southerly winds helped push temperatures to nearly 20C. New record highs were established at Trudeau Airport, 17.8C beating the old record of 17.5 set in 1999. Records were also set at Sainte-Anne and L'Ile Perrot at 20C, St Anicet and Cornwall, Ontario at 21.3C (70F), Ottawa 19.4C and Toronto 18.3C.

A strong cold front swept across the city of Montreal around 7pm last evening with powerful winds, thunder and lightning. The strongest wind gust of the year was observed at Trudeau Airport around 6:50pm at 107km/h (67mph). Wind gusts all night have been frequently over 80km/h in Montreal. The wind knocked out power to over 45,000 customers in Quebec. That number is down this morning as Hydro Quebec crews work to repair the damage. A roof was even ripped from a home on Beaudry near St. Catherine Street. No injuries were reported. Heavy rain fell along the front as well as yesterday morning with 16mm reported at the airport and on L'Ile Perrot.

East Coast Snowstorm
Temperatures are down this morning and will stay there all day. After the summer like warmth on Monday, we will be lucky to surpass 5C (41F) today in Montreal. The other story this morning is the potential east coast snowstorm. That front that brought us the wind will stall along the east coast and allow low pressure to develop off the North Carolina coast and move northeast. The storm will pass near Cape Cod on Wednesday night. Snow is forecast to fall across a wide swath of New England, Atlantic Canada and the northeast US. This comes during the busiest travel time of the year stateside, the Thanksgiving holiday. The potential storm has prompted a wide range of watches and warnings for 15-30cm (6-12inches) of snow. At this time is looks like the snow will just brush the border regions of southern Quebec.
