This week's forecast calls for a precipitous drop in temperature from the prolonged “January thaw” the city has lately been experiencing, with the mercury dipping to a projected low in the vicinity of -8C on Monday and going even lower as the week progresses.
Mid-week will bring the deepest freeze, bottoming out at a nippy -16 C on Thursday. That'll be the coldest it's been in Toronto all winter.
The cold snap will come as a bit of a shock to the system after what Environment Canada climatologist Dave Phillips calls “one of the longest January thaws that we've ever had” — 16 days in a row from Jan. 4 .
“I've never seen a January where we had such a consecutive, long period (of thawing). So people were thinking ‘My gosh, this is all winter has got. It's no issue,' ” “But overall, if you look at Toronto over the last 70-some years, typically the coldest week is this week coming up.
“This is what we call ‘the dead of winter.' If you graph the temperatures throughout the whole year, they typically bottom out here and then, anywhere from about the 22nd to around the 28th, they actually begin a kind of slow rise upward.”
While the week could see it getting frostier than 2012's coldest day — -16.5 C on Jan. 3 — this weekend's extreme winds will die down, and there's little likelihood of “any big dumps of snow” beyond a few flurries toward the end of the week.
