Potential for severe storms puts outdoor plans in jeopardy in Ontario
Plan ahead if you're out and about in southern and eastern Ontario Saturday. Conditions will be conducive for thunderstorms, some of which could be severe, so make sure you stay close to safe shelter in case of foul weather
The first full weekend in July may see storms fire up in a portion of Ontario, so keep an eye on the sky if you have any outdoor plans Saturday.
It’s a summery pattern over Ontario as hot and humid air remains locked in across the region, ripe for thunderstorm development in southern and eastern Ontario. Some of the storms could turn severe, especially in eastern sections where there is also a low, but non-zero risk of a rotating cell.

Storms build across Ontario on Saturday
Daytime temperatures are likely to climb into the middle to upper 20s throughout southern and eastern Ontario, with slightly cooler temperatures expected into cottage country.
The heat and humidity will provide ample fuel for thunderstorms to spark on Saturday as a low-pressure system continues to meander through the Great Lakes.
Scattered thunderstorms are possible through the day Saturday from Sudbury all the way down to the Niagara Peninsula, including the Greater Toronto and Hamilton Area.

The best dynamics for severe thunderstorms will spread over parts of cottage country and eastern Ontario, including Ottawa and Bancroft.
Any of the stronger storms that develop Saturday could produce heavy rainfall, hail, and gusty winds. There is also the chance of a rotating storm in eastern Ontario, as well. It is low but it can’t be ruled out .
Given the slow movement of the thunderstorms and the amount of moisture in the atmosphere, watch out for localized flooding on area roads beneath any of the heavier storms that fire up.
Looking ahead, nicer and more seasonable temperatures look to spread over southern Ontario to end the weekend on Sunday. We can expect hot sunshine to creep back in to start the week.
