Severe storm risk pops up again Friday across Ontario, Quebec
Scattered showers and thunderstorms will continue rolling over Ontario through Friday morning. A renewed risk for severe storms will pop up Friday afternoon.
We saw some rough weather across southern Ontario on Thursday as a low-pressure system slid across the area. Hefty thunderstorms produced torrential downpours and even prompted a tornado warning near Milton during the afternoon hours. This system isn’t done with the region just yet.

Friday will see another risk for stormy weather from Windsor to the St. Lawrence as the low-pressure system responsible for the foul conditions makes its way east.
Rain and storms are likely to continue overnight Thursday in southern Ontario, pushing into the National Capital Region in time for the Friday morning commute. Rain will move into the Montreal area later in the morning.
The day’s instability will see a renewed chance for thunderstorms to develop over the region by the afternoon hours.
Plenty of tropical moisture streaming over Central Canada will lead to a continued risk for heavy rain in any storms on Friday.

These storms should move a little faster than those we saw on Thursday, though, cutting down on the risk for localized flooding. Even so, stay aware of hazardous conditions and make alternate travel plans in case you encounter flooded roads.
In addition to heavy rainfall, some severe storms are possible across portions of eastern Ontario, the Montreal metro, and the Eastern Townships as we head into the afternoon and evening hours.
Any of these stronger storms could produce strong wind gusts and small hail.
