Despite a mild-feeling morning, temperatures will drop this afternoon — and keep dropping tonight.
One thing that won't drop is the wind.
Environment Canada says that temperatures will reach a high of about -15ºC today, but cold air will flood in through the afternoon, dropping the mercury to -20ºC, as winds pick up to 40 km/h, with gusts of up to 60 km/g. That could take the wind chill to -31.
A mix of sun and cloud today will persist this evening, with a few clouds overnight. Winds will lighten a bit overnight, but temperatures will drop to -33ºC overnight, with an extreme wind chill of -40.
Increasing cloudiness is expected tomorrow, with a 60 per cent chance of flurries Thursday evening. The high will be -16ºC.
Friday should see sun, with a high of -21ºC but temperatures will plummet to -41ºC (that's the temperature, not the wind chill) on Friday night. That's within a degree of the record for that date.
Saturday will see sun and a high of -24ºC, followed by a high of -20ºC on Sunday.
Clear skies persist into next week, with slightly better temperatures. At this point, the forecast calls for a high of -18ºC on Monday and a high of -14ºC on Tuesday.
The normal high for this time of year is -5ºC; the normal low is -15ºC.
The warmest it's ever been on this date was in 1988, when it reached 7.5ºC. The coldest ever was in 1962, when it dropped to -39.4ºC.
