Another record high unofficially fell Tuesday in Sarnia-Lambton.
The temperature climbed to 17 C at 12 p.m., and to 20.7 C by mid-afternoon, surpassing the previous record for February 27 of 13.6 C set in 2000.
Environment Canada Warning Preparedness Meteorologist Steven Flisfeder said the mild weather won't last long. The national weather agency expects the temperature to plummet to minus 4 C Wednesday afternoon.
"The warm temperatures that we'll be experiencing today [Tuesday] and early tomorrow [Wednesday] are a push of warm moist air from the southern United States, really fueling the intensity of that low pressure system," said Flisfeder. "And then that sudden drop in temperatures is going to be associated with an arctic air mass following the cold front associated with that low pressure system."
Flisfeder said along with the drop in temperatures on Wednesday, we can expect to see some messy weather.
"There's going to be some risks associated in the form of rain showers and thunderstorms," he said. "That's going to continue throughout tonight and early tomorrow and strong winds as well could be possible across the region. And then once that cold front sweeps through, that's going to drop temperatures very quickly, so there is the potential for a flash freeze. So dangerous roadways and walkways are possible. The cold front also brings the possibility of heavy flurries."
The normal high for this time of year locally is 2 C.
