Châteauguay Valley Weather September 1-11, 2021

Peter Finlayson, Ormstown Weatherman

So far, September seems like it’s been a wet month with overcast skies and rain almost every day. While there have been showers most days, they have only totalled 27 mm of precipitation, which is average for the first third of the month.

The trend of localized showers that the area has experienced for a good part of the summer has continued. In the first ten days of September, the Environment Canada weather station in St-Anicet reported only 19 mm of rain for the month to date, while Ste-Clothilde reported only 17 mm and l’Acadie 23 mm.

The month also continued on the plus side of average for temperature, with the average sitting at 16.8° C, slightly above the normal of 16.2° C. The forecast for the rest of the month is for temperatures to be well above average except for September 26th, when the nighttime low is forecast to be 1.0° C – we shall see!

That little bit of extra heat also kept the heat units ticking along, with 224 CHU so far in September, which is slightly above the prorated average for the first ten days of the month based on the normal for the month of 569 CHU. The season-to-date total is now 2973 CHU, with the start of the growing season measured from May 10th.

The leaves on a few trees have started to turn yellow, as are many soybean fields, but solid signs of fall – heavy dew and cool nights – have yet to appear.
