Tropical storm remnants fuel storm risk in Ontario and Quebec

We’re steeped in muggy air across Eastern Canada, and it’s not going away anytime soon. The remnants of Tropical Storm Fred will move near the Great Lakes over the next few days, providing the opportunity for showers and storms for portions of Ontario and Quebec. The tropical moisture could allow storms to produce heavy rain. A look at the storm threat, below.

WEDNESDAY: FRED’S REMNANTS COULD SPARK SCATTERED THUNDERSTORMS

The remnants of Tropical Storm Fred will move into the northeastern United States on Wednesday after producing several tornadoes and widespread flash flooding in the Carolinas.

While the bulk of the system’s heavy rain and storms should remain stateside, a surge of Gulf moisture aloft will spill over Ontario and Quebec on Wednesday. Fred’s remnant moisture will fuel a risk for showers and thunderstorms across the region.

The far-reaching storm chance stretches from Windsor to the Gaspé Peninsula, including just about every major city in between. Lake breezes in southwestern Ontario will influence the development of thunderstorms across the region during the heat of the day on Wednesday.

The surplus of tropical moisture could allow thunderstorms to produce heavy rainfall, which could lead to localized flooding issues if any storms sit in one spot for too long. The strongest storms could also produce strong wind gusts and small hail.

Wednesday will begin a stretch of above-seasonal temperatures across the region, with highs in the upper 20s likely across much of southern Ontario and southern Quebec. Humidex values will approach the mid- to upper 30s during the afternoon hours.

LATE WEEK AND THIS WEEKEND: REMAINING WARM AND HUMID

Thursday will see a renewed chance for thunderstorms across southern Ontario, though it’s likely the threat will miss the Greater Toronto Area.

Otherwise, conditions aren't likely to change much through this weekend. Temperatures will stay warm, humidity levels will remain sticky, and just about each day will feature a chance for pop-up showers and thunderstorms.

Beyond, very warm and humid days continue through early next week as tropical moisture surges north from the distant Gulf of Mexico, though most of the time it will be dry and there will be plenty of sunshine.
