Ontario: Frigid Thursday gives way to spring-like weekend warmth

Wednesday, February 19th 2020, 8:03 pm - Thursday will be marked by the kind of cold you'd expect from mid-February, but it'll soon give way to a comfortably spring-like weekend.

Aside from some lingering lake-effect snow bands in the usual snowbelt areas, the bigger story Thursday will be the cold, with overnight lows below -10°C for some. However, though Friday morning may be frigid, it will mark the beginning of a warmup that will take weekend temperatures soaring near the double-digit mark. A more detailed breakdown, below.


  • Thursday the coldest day of the week, daytime highs in the negative single-digits
  • Lake-effect snow lingers for snowbelts through the day Thursday, ending late-day
  • Temperatures rise into the weekend, nearing 10°C by Sunday
  • Keep track of weather alerts in your area.


Wednesday marked a significant departure from early-week warmth, and Thursday will be colder still.

Daytime highs in the negative single digits will be widespread across the south of the province, which isn't really too far off from what you'd expect in mid-February. However, keep in mind that overnight lows will be much colder, possibly below the -10°C mark and feeling colder with the wind chill as we head into Friday morning.

As for the snow, winds will wane somewhat Thursday, but will still be enough to trigger some lake-effect snow, lasting on and off through the day Thursday for communities that already saw some flakes on Wednesday. The snow ends later Thursday, and for the most part, that should be it for precipitation over the next few days.

Though Friday morning will start out frigid, temperatures will start their drastic rebound, leading into a weekend that will seem like an early taste of spring.

By Sunday, temperatures will be well above seasonal, and in fact not far from double-digit daytime highs, along with abundant sunshine for the whole weekend.

ON Sunday

"We'll be seeing our longest stretch of dry weather so far this winter as conditions look to remain calm from Friday right through next Tuesday," says meteorologist Tyler Hamilton. "This will be a gorgeous weekend, especially by winter standards."

This won't be the signal for an early spring, however, as much colder weather is expected by the second half of next week and into the start of March as well.
