It seems we have a trend this fall of record-breaking warmth on Wednesdays. Last week we managed back to back records of 22.7C (72F) and 24.4C (76F). Today, the temperature is knocking on the door of the 1948 record of 21.7C (71F) at this hour, currently 21.4C (70F). Record or not, today's high is way above the normal of 7C (45F), but as I wrote last week, what is "normal" anymore when it comes to our weather.
Gusty southwest winds ahead of a cold front are responsible for the surge in warm air. They are reaching speeds of 60-70km/h here in the St. Lawrence Valley. Hydro-Quebec is reporting scattered power outages as a result of the wind, with just over 13,000 in the dark.
Temperatures will begin to cool once again this evening, dropping to 9C (48F) tonight and remaining fairly steady on Thursday. A few showers are possible, but the bulk of the moisture with this system will remain well to our north.
High pressure will build into southern Quebec for a sunny, but chill Saturday, before clouds, warmer temperatures and some rainfall arrive for Sunday into Monday.
The current trend of a cool day or two, followed by a significant warming trend is expected to persist well into November.
October was warm and dry in Montreal. We only measured 25mm of rain, well below the normal of 91.3mm. The average temperature at Trudeau Airport was 11C, also well-above the normal of 8.9C.

The central portion of the continent has had some very active weather over the course of the past week, including some rare November tornadoes. At least a half dozen tornadoes occurred across parts of Texas and Oklahoma on Sunday. Numerous homes were demolished, with at least 11 injuries reported. There were also reports of significant flash flooding, with up to 300mm of rain falling from north Texas into Missouri.

Meanwhile the topics have awakened again. Early Wednesday morning, Rafael became a hurricane, located 205 km south, southeast of Havana, Cuba. Rafael has 175km/h winds and is expected to strengthen to a category 3 storm before landfall in western Cuba late Wednesday. Forecasters then expect the storm to meander around the southern Gulf of Mexico into the weekend, while weakening. So far the only impacts to the US mainland are expected to be gusty winds and a 3 foot storm surge in the lower Florida Keys.
