Don’t get used to today’s balmy weather: temperatures are set to plunge back below zero by Wednesday, according to Environment Canada.
“It’s been a bit of a yo-yo in the past 24 hours and it’s not going to stop,” said Geoff Coulson, a meteorologist with the weather agency.
Toronto and the GTA saw temperatures in the minus teens Monday before the mercury shot up, with most areas at two to three degrees above zero today, Coulson said.
But the reprieve will be short-lived. Patchy periods of freezing rain or drizzle throughout the day will change to snow as temperatures drop back down below freezing at around midnight tonight.
About 2 cm of the white stuff could accumulate overnight and as the snow continues throughout much of Wednesday, Coulson said another 2 to 4 cm could fall throughout the day.
Meanwhile, frigid temperatures are in store for the rest of the week and into the weekend. Coulson predicted a daytime high of -5C for Wednesday and highs of -8C and -9C for Friday and Saturday. The normal high for this time of year is -2C, he said.
Although Environment Canada issued a special weather statement this morning highlighting a possible flash freeze overnight, Coulson said that will depend on the current patchy drizzle giving way to more rain this afternoon.
Coulson said an official warning for Toronto and the GTA is unlikely but did caution motorists to watch for areas with liquid build up today to turn into icy patches by Wednesday.
