Warm September continues across southern Quebec

Warm, muggy weather will dominate the east coast and southern Quebec once more this week. (AccuWeather)
The hot and dry summer across southern Quebec has stretched right into September. With two thirds of the month in the record books, the average high temperature has been a sweltering 24.3C (76F), the normal should be 20.6C (69F). To date 18 of the 19 days in September have featured above normal temperatures. This trend continues Monday morning, with Montreal at 9 a.m. reporting 21C (70F), the warmest location in the country. Partly sunny skies and humid conditions are forecast today through Wednesday, with high temperatures well above normal at 26C (79F). The normal high for September 19, should be 18C (65F) for Montreal. With the exception of a couple of nights, the overnight lows have been very mild as well, averaging 13.5C (55F), the normal should be 10.3C (50F).

There has been a slight improvement in the drought conditions in southern Quebec after the rainfall of late August. September however has been very dry once again, with only 23.4mm of precipitation so far. Montreal normally receives 83.1mm of rainfall for September. We have plenty of catching up to do. Showers and thunderstorms over the weekend missed Montreal, with only 3 or 4mm falling in the city. The next chance for rain will come along a cold front Thursday. Cooler, more seasonable weather is expected to arrive by next weekend. However it will be short lived, as the much warmer than normal Great Lakes continue to modify the cooler fall air as it moves southeast from northern Canada.
