Thunderstorm risk will bubble up across much of southern Ontario on Sunday afternoon as warmer temperatures at the surface sharply contrast with colder air aloft. Instability could fuel thunderstorms along cold front pushing into the region.

By late Wednesday afternoon, a front will slice into unstable atmosphere, acting as trigger mechanism for development of powerful storm cells. Supported by wind shear from approaching trough, some storms will have rotation chance -- leading to threat for tornadoes.

(1/2) Snowfall projections for Central Canada. Through Dec. 25, some areas in the snowbelt regions in Ontario may wind up with 30-50 cm of snow, thanks the lake-effect setup following the passage of the storm. GTA may see 5-15 cm of snow.

Take this with a grain of salt but here’s a look at possible snowfall rates in time for the evening commute. The worst time for the GTA to see a heavy band of snow (5-6 p.m.), with possible rates of 3-5 cm an hour. Regardless of the exact rates, snow will be heavy.

In addition to the heat, forecasters are watching the potential for more organized severe storms on Wednesday afternoon as a dynamic weather system tracks into the Great Lakes. Parts of the risk area may potentially see supercells.

Isolated tornado risk in extreme southwestern Ontario on Wednesday. Storms east of Lake Huron could still become severe, but hail and wind gusts are main hazards. Greater risk of tornado development in Michigan, with less of a cooling influence from Great Lakes.
