Rumbles of thunder may disturb your slumber across much of southern Ontario Friday night as a potent front pushes across the region.
Evening thunderstorms rolling in from the west will persist through the overnight hours, bringing a risk for severe weather to a wide swath of southern and eastern Ontario.
While the evening storms may pack a greater punch, the main threat with the overnight storms will be torrential rainfall and localized flooding.
Keep an eye on the radar as you wind down for bed tonight, and stay alert for watches and warnings that may be issued in your area.
STAY SAFE: How severe weather alerts are issued, and potentially save lives
A low-pressure system powering across the country will make its mark on southern Ontario on Friday, just in time to kick off the long weekend.
There’s enough instability and favourable dynamics present over southwestern Ontario for some of Friday evening’s thunderstorms to turn severe. These storms could pack strong wind gusts, large hail, and possibly even a brief tornado threat before the sun goes down.
Storms will start to lose a bit of their edge as they make their way into the Greater Toronto Area (GTA) after sunset and into the overnight hours, with the severe weather threat transitioning over to torrential rainfall.
The atmosphere is packed with moisture and these slow-moving storms will train over some of the same communities, bringing the threat for localized flooding throughout the GTA.
Stay alert during periods of heavy rainfall. Remember: never try to drive across a flooded roadway. It’s impossible to tell how deep the water is until it’s too late.
The rain will clear out of the region in time for Saturday, bringing sunny and warm temperatures for the rest of the long weekend.
