The front will bring severe thunderstorms and tornado warnings across much of southern Ontario.\nEnvironment Canada is warning several parts of southern Ontario that thunderstorms are expected to develop this afternoon. The storms are predicted to become severe with wind gusts of 100 km/h and heavy rainfall. They are also warning residents that the storms have the potential to produce tornadoes.\nAlthough thunderstorms and tornados are a possibility on Friday evening, heavy rain and strong winds are the main threats. Weather experts will be monitoring for tornadic activity throughout the day.\n"The better instability remains in the Ohio Valley and Michigan, but we have a lot of dynamics associated along the cold front Friday evening, so we can't rule out some isolated severe thunderstorms in southwestern Ontario," explained Weather Network meteorologist Tyler Hamilton.\nThankfully, even though Friday will be a total bust, summer is expected to return on Saturday. Temperatures will rise into the mid-20’s on Sept. 14 with plenty of sunshine.\nThe seven-day outlook for the Toronto area is looking pretty good so far.\nThe Weather Network\nSadly, though, next week is going to be summer’s last stand.
