Severe Thunderstorm Threat Continues Wednesday

Powerful line of thunderstorms cut across parts of southern Ontario earlier today with reports of hail and strong, straight-line winds. The tops on one of the storms (near Listowel) reached up to 50,000 feet in the sky.

By tomorrow, the dynamics are in place for more widespread, locally severe thunderstorms with the warm front setting up from near Parry Sound to Ottawa. Areas along and south of this front will be most at risk to severe thunderstorms as the air will become very unstable due to heating and higher humidity out ahead of the approaching system.

The greatest threat tomorrow will be small hail and damaging, straight-line winds. However, an isolated tornado can't be ruled out either, especially just south of the warm front.

I will keep you posted with the severe weather on my twitter @BrettAWX.
