Strong high pressure has led to a frosty morning Friday, in Montreal, with temperatures dropping close to the freezing point at many locations. Most locations off island have already had the first frost of the season, so while a frost advisory will likely be posted Friday night as well, the growing season is coming to an end.
Precipitation remains at a premium in southern Quebec this month as it has most of the summer an early fall. To date, only 22.4mm of rain has fallen at Trudeau Airport, falling on two days this month, Drought conditions remain severe to extreme across a wide area from central and southern Ontario across the St. Lawrence Valley and into northern New England.

| While the fall weather this year has been spectacular, we desperately need rain. Only 22mm has fallen at Trudeau Airport in October, with large parts of the region reporting severe to extreme drought conditions. The wildfire risk remains very high to extreme with outdoor burning prohibited or strongly discouraged for most parts of southwestern Quebec. (Valley Weather) |
High pressure will remain in control of our weather through the upcoming weekend, but there is some good news on the horizon as far as rainfall is concerned. Temperatures will warm over the weekend, from cool daytime highs of 13C (55F) Friday, to near-summer warmth Sunday at 22C (72F). Gusty southwest winds are expected Sunday, in advance of a cold front that will usher in a pattern change next week.
Two areas of low pressure will pass north of Montreal next week, dragging several frontal boundaries across southern Quebec. Clouds and showers wil prevail for a good portion of the week, with estimates of 25-50mm (1-2 inches) of rain for the week. Temperatures will trend cooler as well, with highs dropping into the lower teens.

Active Weather Week
It has been a very active weather week across many parts of NorthAmerica, despite our quiet weather here in Montreal. A strong Nor'Easter last weekend remained largely south of Montreal, producing widespread coastal flooding from North Carolina to Long Island. Homes were inundated and roads washed away. Thousands were left without power from New Jersey to North Carolina.
Meanwhile in western Canada, a strong fall storm produced the first significant snowfall of the season across parts of southern Alberta and Saskatchewan on Thanksgiving Day. Travel was extremely difficult, especially in Alberta. Some locations reported over 10cm of fresh snow, along with wind gusts over 80km/h.
In Alaska, the remains of Typhoon Halong produced strong winds, heavy rain and a devastating storm surge resulting in catastrophic flooding. Several homes were washed away, leading to the evacuation of over 1500 residents. Several villages in the western part of the state were flooded with homes washing out to sea. One death has been reported so far.
