If you thought it was cold Tuesday night, the conditions will be even more extreme Wednesday night.
Environment Canada's extreme cold warning remains in effect.
Sarnia's previous record low temperature of -21.7 C (-7 F) set in 1966 will likely be broken Wednesday night with the mercury expected to plunge to -25 C (-13 F). The overnight wind chill is expected to be -39 C (-38 F) creating the risk of frostbite in minutes.
It'll still be bitterly cold Thursday with the temperature beginning to moderate Friday and climbing to plus 4 C (39 F) by Sunday.
Sarnia's Inn of the Good Shepherd managed to accommodate an overflow Tuesday night.
Executive Director Myles Vanni says all 25 beds at the Good Shepherds Lodge on Confederation Street were filled as well as some of their overflow beds.
"We've had seven people that we've been able to get into an overflow program, we are so full at the lodge right now because of the housing shortage, but we worked with a number of community partners to be able to provide overflow beds so people can get out of the cold," said Vanni.
Vanni says their overflow program can take up to about 14 people.
Canadian Automobile Association Public Relations Manager Kaitlynn Furse said they've been very busy all week across the region from Windsor to Kingston.
"We received about 10,000 calls on Monday, 8,000 calls yesterday and typically on a winter day we'll receive about 4,000 across that territory, so we're seeing double numbers, which is pretty standard for when you are experiencing these types of really, really cold weather conditions," said Furse.
Furse said in the Sarnia area they received 67 calls Monday, 38 calls Tuesday, and nearly 20 by mid-morning Wednesday.
She recommends getting your battery checked proactively in advance of extreme weather because they typically only last three to five years nowadays.
Furse also reminds motorists to have a safety kit in their vehicles.
