Spectacular weather forecast for Montreal to end September

Strong high pressure will remain in control of the weather over southern Quebec during the entire upcoming week. We can expect near-perfect fall weather, sunshine and highs in the low to middle 20s. The only exception was a few high clouds from tropical storm Ophelia over the weekend, and gusty northeast winds from the same system on Monday.

Strong high pressure is in control of the weather across southern Quebec, with nothing but sunshine and warm temperatures expected through the entire upcoming week. The area of high pressure is forecast to remain in place across the central portion of the province, keeping any inclement weather well south of our region.

The remains of tropical storm Ophelia, which made landfall Saturday in North Carolina, are located across the middle Atlantic states, with showers and gusty winds. Clouds from this system reach as far north as central Vermont and New York. The only practical weather expected here in southern Quebec from Opehila, will be a gusty northeast wind, between 30-50km/h expected during the daylight hours Monday. Winds should ease after sunset.

The first day of fall was Saturday, greeted with summer like sunshine and warm high temperatures in the low to middle 20s. This trend will persist right through the upcoming week and even beyond into next weekend. High temperatures will be in the 20s (68-75F) with overnight lows either side of 10C (50F). I see no end to this perfect fall weather before next Monday or Tuesday at the earliest, with a cold front arriving from the northwest.
