Humidity lifts a bit for Ontario, unsettled week ahead

Tuesday, August 25th 2020, 6:08 am - More moderate temperatures aren't far off in Ontario, but between now and then is another round of potentially severe thunderstorm risk.

It's been a hot and humid few days for Ontario, a perfect primer for thunderstorms. It looks like we can see some overnight lightning, as there are favourable conditions to light up Ontario skies. Watch meteorologist Tyler Hamilton's video above to hear about the lightning potential.


WEATHER HIGHLIGHTS

  • A slightly less humid Tuesday, though still surpassing 30s on Tuesday
  • Unstable week ahead, possible thundershowers
  • Humidity begins to subside through mid-week, remnants from Laura end of the week

TUESDAY AND BEYOND: MORE RAIN, HUMIDITY TO DROP, LAURA REMNANTS?

A cold front moving in Tuesday will bring a bit of rain and the risk for thunderstorms in southwestern Ontario in the afternoon, though it all looks relatively mild.

By Wednesday, there looks to be a fairly sharp boundary across southern Ontario, so we will see a very tight temperature gradient (extreme humidity across the southwest and cooler air coming in from the northeast). This could bring the threat for potentially severe storms.

Wed ON

Overall temperatures bounce back somewhat Thursday before once again dipping down on Friday, with both days featuring some storm chance.

Moisture from Tropical Storm Laura could possibly impact southern Ontario Friday night into Saturday. Rain, gusty winds and thunderstorms are all on the table. Beyond, the following weekend looks to be temperate and, for some, even fall-like.

Keep an eye on the forecast as we continue to monitor Ontario's weather outlook.
