Record-warm temperatures could be in store for Dec. 24.
There's no chance of snow and Environment Canada's Geoff Coulson predicts a high of 13 C.
"A real mild one in store for Windsor and southwestern Ontario," said Coulson. "In fact, if we do reach 13 degrees Celsius, it'll be a record for the warmest Christmas [Eve] on record. The warmest was 12 [degrees] in 1982."
The official record high is 12.6 C in 1982.
And, forget the chance of a snowstorm. Coulson said there could be thunderstorms on Christmas Eve.
That could be good news for travellers, since the roads aren't expected to be too messy.
Wind, not snow, is the weather risk this Christmas Eve.
According to Environment Canada, there's a wind warning in effect for the Windsor, Chatham-Kent, Rondeau Park, Leamington and Essex County areas.
Periods of rain, patchy fog, a few thunderstorms and very mild temperatures are expected Wednesday.
Winds of 60 km/h, gusting to 90 km/h, are likely in many open areas. Some gusts near 100 km/h are also possible for regions bordering the northeastern shore of Lake Erie.
"It's actually a really big storm system," Coulson said. "There's one sitting over Iowa and will be replaced by one from the American Deep South."
The warm streak won't last, however, as more seasonable temperatures will return by the end of the week.
According to Environment Canada, the record high of 16.2 C set on Christmas Day in 1982 isn't in jeopardy.
The high expected on Christmas Day this year is 4 C.
