After a stretch of warm weather, Sarnia-Lambton will begin to return to more seasonable temperatures.
Environment Canada Warning Preparedness Meteorologist Monica Vaswani said Wednesday, November 4, saw the warmest night on record for that date.
"The previous record for the minimum [temperature] was 12.2 degrees in 1994, and we ended up having 15.3 degrees as the minimum," she told Sarnia News Today.
Environment and Climate Change Canada began keeping track of records in 1948.
Vaswani clarified minimum temperatures represent the coldest time of the day, overnight lows, while maximum temperatures are daily highs, usually reached by mid-afternoon.
"That meant basically it was a very warm night relative to the norm," said Vaswani.
Normally, this time of year calls for daytime highs of 10 C and overnight lows of 2 C.
"Once we move into Friday and over the weekend, we are actually getting closer to the seasonal degree mark because basically, our winds are starting to shift, bringing in that cooler air," said Vaswani.
Friday's forecast calls for periods of rain, while daytime highs will hover around 10 C throughout the weekend.
"Our overnight lows are still a tad bit on the warm side. We're still looking anywhere between 4 C and 5 C for our overnight lows. Closer to seasonal than we have been over this last week," she said.
Vaswani said for at least the first half of November, it does look to be above seasonal on average.
"I believe many of our climate models are showing that general trend for the winter," she said. "Part of that is the strong El Niño that has been a noteworthy discussion for a while; as a result of that, we do often see milder than normal temperatures."
Vaswani said that doesn't mean we won't see the occasional cold snap.
