Ontario: Chance for severe thunderstorms on Tuesday

Monday, September 2nd 2019, 8:26 pm - There is the chance for thunderstorms to turn severe in southern Ontario on Tuesday

Southern Ontario will see the chance for severe weather on Tuesday afternoon due to the influence of a system tracking across the northern regions of the province. The possibility for severe thunderstorms will stretch across the southern regions into the evening and the main hazards include heavy rainfall and powerful wind gusts. Details on the timing of these storms, below.


WEATHER HIGHLIGHTS:

  • Brief warmup for Tuesday, potential for storms by the evening and into the overnight
  • Cooldown expected by next weekend

WATCH BELOW: TRACKING THE THUNDERSTORM ENERGY, RAINFALL

Warm air will continue to surge into Ontario for Tuesday, but the bump in temperatures will quickly come to an end as a potent system tracks across northern Ontario and into central Quebec by late Tuesday into Wednesday.

This will bring widespread rain near the track of the low and thunderstorms to the south, as a cold front sweeps across the region. When storms do pop up, the risk begins later in the afternoon for western portions of southern Ontario (Georgian Bay, eastern shores of Lake Huron and southwestern Ontario), then spreading to the GTA for the evening, and to eastern Ontario through the overnight.

Depending on the track and timing of the system, some storms coming in from Michigan may become severe later Tuesday afternoon and into the evening, bring the chance for strong winds and heavy downpours.

IS THIS OUR GOODBYE TO SUMMER?

Fall-like weather spreads from the Great Lakes to Atlantic Canada for the second half of next week with a reinforcing blast of even cooler weather from the eastern Prairies to the Great Lakes for next weekend. However, there is a struggle to lock down the pattern because of the uncertain future track of what will be the remnants of Dorian.

"Some models are shockingly cool for next weekend across Ontario and Quebec, but models are really struggling with the details of the pattern, due in part to the uncertainty as to where Dorian will be by that time and how its track will impact upstream weather systems," says Weather Network meterologist Dr. Doug Gillham.
