With severe storms coming to southern Ontario, staying indoors might be a good idea. An Ontario Tornado threat might be a possibility after a severe thunderstorm watch was issued for certain cities in southern areas of the province this Tuesday afternoon. With conditions like these, The Weather Network suggests there could be an isolated tornado or two.\nWith the chance of feeling part of Hurricane Dorian's wrath, Ontario could face heavy rainfall and the potential for tornados.\nThe possibility for severe thunderstorms goes across the southern region of Ontario this evening with powerful winds and rain making their way into the GTA.\nSevere thunderstorms are especially likely along the Huron shores and through southwestern Ontario, where there is also a slight tornado threat into Tuesday night #ONstorm— The Weather Network (@weathernetwork) September 3, 2019\n"The greatest chance for severe thunderstorm development will be closer to the Huron Shores and down into southwestern Ontario, where there is also a slight tornado threat Tuesday night," says meteorologist Matt Grinter for the Weather Network.\n"We will have to monitor the morning convection and daytime cloud cover, however, as that could hinder the severe threat for later in the day."\nThunderstorm outlook for Ontario valid for Wednesday and Thursday. #ONstorm pic.twitter.com/QuP0EapikL— ECCC Weather Ontario (@ECCCWeatherON) September 3, 2019\nTUE, SEP 3, 2019: Severe Thunderstorm Risk This Late Afternoon, Evening & Overnight; 95km/h+ Damaging Wind Gusts, Isolated Flooding, 1-2.5cm Hail, Frequent Lightning, & An Isolated Tornado Cannot Be Ruled Out #onstorm #onwxDetails: https://t.co/0xPFoPKBoN pic.twitter.com/DTEVKS1qMw— Instant Weather ON (@IWeatherON) September 3, 2019\nHail and isolated flooding could also be a potential factor during this severe thunderstorm threat.\n#ONStorm Flood Watch – Erie Shore Drive, Lake Erie and Lighthouse Cove, Lake St. Clair – September 3, 2019 – 7:45 a.m. https://t.co/3UVOLD4lWb— Jason Redlarski (@JPR_em) September 3, 2019\nAlthough this might be a sign that summer will last a while longer, fall-like temperatures are set to hit southern Ontario for the rest of this week.\nTemperatures could hit around the 20°C mark across the GTA by Wednesday.\nNorthern and western parts of the GTA will remain in the mid to high teens, according to The Weather Network.\nCanadian weather tends to go through drastic changes so although the possibility of a severe thunderstorm is high for today, chances of a tornado hitting the GTA may be low.\nNevertheless, be prepared for anything!\nThis cover photo has been used for illustrative purposes only.\nThere are stories everywhere.
