Out of the frying pan and into the freezer.

That’s going to be the weather pattern for the next few days in London, with a possible record high of 18 C Friday, followed by a weekend that forecasters say is likely to end with a burst of snow flurries.

Geoff Coulson, a meteorologist with Environment Canada, says if the combination of conditions were a movie, its title would be Revenge of the Fall.

In other words, the usual drab, dreary weather normally associated with November — which we haven’t seen much of in Southwestern Ontario so far — will finally reassert itself.

“If you can get outside (Friday), take that opportunity,” he urged Londoners.

Coulson said that October and November have felt a lot more like September so far. “My dog is still busy digging holes in the backyard because the ground isn’t frozen,” he said.

The current record for November 18 is 17.8 C, set in both 1953 and 1941. The seasonal norm is 6 C.

With a projected high of 18 C looming, Coulson says Friday could be the last day of double-digit temperatures until next spring. So if you like wearing shorts, this may be your last hurrah.

“This was a pretty amazing run that we’ve had so far,” he said.

Conditions so far this November have been atypically mild and sunny, he noted. November is ­usually more of a transition month.

There was even an appearance by the supermoon earlier this week, which typically would have been blocked from sight by low cloud banks.

After a high of 8 C Saturday, Sunday temperatures will plunge to a high of 2 C and a low of –1 C.

“So we’re watching a big system that’s coming out of the American Midwest,” Coulson said.

That weathermaker will bring showers to the area Saturday, which will turn to flurries by the end of the weekend. In places north of us, like Thunder Bay, Environment Canada is calling for as much as 30 centimetres of snow.

Though it’s too early to predict whether Christmas will be white, Coulson says his models indicate the second half of December and early January will be more seasonal.
