Hazy & hot Friday - much cooler weekend

Hearing from a few of my friends and colleagues that they are ready for fall. What? To each their own I suppose, but we clearly need more summer, it arrived late, it was just like that, and now it appears to be taking an early exit, especially across the west. Snow and frost across Alberta already this week with more cold weather in store for next week.

NOAA update showing the expected cold weather next week.

That being said we are in for a very warm day with near record breaking warmth in Quebec and we should see some new records posted in Ontario. Temperatures are already in the mid 20's and we are looking at 29 to 33C (85-92F) for most regions. The record high for Montreal is 33.3C set in 2008, we have an outside chance of it in the city but the airport has been notoriously cool this summer, as already stated in previous blogs, so just reaching 30C (86F) at Trudeau may be a lofty goal. It will also be windy today out of the southwest ahead of the sharp cold front, gusting to 60km/h in the St. Lawrence Valley. The forecast heat and humidity has prompted warnings across southwest Ontario and special weather statements here in Quebec. Humidex values may approach 40C by this afternoon.

Sunshine and humidity will build, with increasing clouds by late in the day. Thunderstorms will develop along that potent cold front later this afternoon in Ontario and across Quebec by late this evening. Some of the storms may be severe in Ontario. On Saturday, skies will slowly clear and it will be much cooler with highs of 21C (70F). Sunday looks sunny and seasonable with overnight lows of  10C (50F) and highs near 22C (72F).
