SD&G – Weather watchers are expecting a mild fall for the Cornwall-area to start this month but, then, watch out!

The Weather Network released its fall outlook Tuesday for September through November and says the first half of hall will see milder temperatures as summer lingers.

But come mid-to-late fall, “a drastic pattern change will help bring a false start to winter, with a time frame currently late October to early November,” meteorologist Erin Wenckstern told Cornwall Newswatch about the “two act story.”

Average high temperatures for Cornwall and SD&G will be 20 degrees to five degrees from September through November.

This is thanks to strengthening El Niño conditions in the Pacific Ocean that are on track to be one of the top three strongest events since 1950.

As for rain and snowfall, there will be many rain-free days in the first half of fall but the changing weather pattern to being the false winter, will also bring an increase in precipitation. Overall, Wenckstern said they are calling for near normal precipitation amount of 10 to 20 centimeters of snow through the late fall and around 200 to 250 millimeters of rain.

Then there’s the age-old question, will it be a white Halloween? Wenckstern said it’s a very difficult question to answer but it’s not out of the question. “As mentioned, the arrival of cooler air to potentially end October will help support the formation of late-fall snow in some areas,” she said, especially in areas where there is lake-effect snow.
