Enjoy the warm temperatures while you can on Friday, because the London region could see it’s first significant snowfall of the season this weekend.
We’ll go from what’s expected to be record-breaking warm temperatures Friday afternoon to upwards of 5 centimetres of snow by Sunday.
“I think a lot of people will probably need to be reminded of where we should be this time of year,” said Environment Canada Meteorologist Geoff Coulson. “Normal highs for the London area should be more around 6 degrees, much of the month so far has been well above that.”
A new warm weather record may be set on Friday, as the forecast calls for sunshine and a high of 18 degrees.
That would beat the previous record of 17.8 degrees set back in 1941.
The forecast will begin to take a turn for the worse on Saturday, with strong winds, rain, and the temperature dropping from 9 degrees.
You might want to plan to limit travel or stay home on Sunday, as we could get upwards of 5 centimetres of lake effect flurries with a high of 1 degree.
Additional flurries on Monday could add a few centimetres of accumulation.
Coulson has bad news for anyone who enjoyed last year’s mild winter.
“I think one of the easier things to say at this point is that there will be more winter this year than what we saw last year, the El Nino is gone, it’s been replaced by a weak La Nina,” said Coulson. “The other thing we can say though, it looks like it’s going to be a slower transition into more winter-like conditions.”
The replacement of a Super El Nino with a weak La Nina means very warm water near the equator in the Pacific has been replaced by slightly cooler than normal water. It may not seem like a big deal, but this change affects the jet stream around the planet and influences weather patterns.
