Severe storms likely in southern Ontario on Friday
Showers will spread across the Greater Toronto Area during the morning hours as a warm front lifts across southern Ontario. Persistent showers are expected in northeastern Ontario in the morning, moving into the Ottawa region by the evening.
WATCH: Severe storms start firing up along Lake Huron shores
Unstable air moving in behind that warm front will set the stage for a round of strong to severe thunderstorms during the late afternoon and early evening hours on Friday.
A cold front pushing in from the west will collide with the unstable air and trigger a strong line of thunderstorms along the shores of Lake Huron and Georgian Bay.
These storms will develop amid an environment capable of supporting 2+ cm hailstones, strong wind gusts of 90-100 km/h, and the risk for embedded rotation. An isolated tornado cannot be ruled out. Damaging straight-line winds and microbursts are also a major threat that will be in play with these storms, which could cause major tree damage and outages.
We’ll see this line then move northeast and weaken as it approaches the Greater Toronto Area overnight.
Saturday will feature improving conditions across most of southern Ontario. The persistent rain will ease across central and eastern portions of the province during the morning hours.
Scattered showers will remain possible through Saturday afternoon, but overall we’ll see conditions clearing up. Temperatures will finally inch into the lower 20s for folks in eastern Ontario.
