We'll see a warmer and drier than normal start to the fall season around Sarnia-Lambton.
The autumnal equinox arrives Tuesday, September 22 at 9:31 a.m.
Environment Canada meteorologist Peter Kimbell said sunny, dry conditions are forecast for the first week of fall.
"The average high for this time of year is 21 C, the average low is 10 C, so the cool weather that we've had the last few days, definitely below normal, will be back to normal or slightly above the next several days, and then normal beyond that," said Kimbell. "Something closer to normal or below normal next week as the trough of low pressure moves into the area, so showers probably returning next week."
Kimbell said normally the chance of any snow in Sarnia-Lambton is unlikely until November.
"The average snowfall in Sarnia in the month of October is 1.8 cm, so the good news is probably no snowfall in September, of course, possible snowfall by the end of October, we typically see about 10 cm of snow in November, so snow is most likely to return by November," he said.
Environment Canada said a relatively hot summer with adequate precipitation should result in a colourful autumn with great viewing of this year's fall foliage in Ontario.
