TUESDAY AND BEYOND: HUMIDITY, RAIN, STORM RISK RETURNS
Tuesday will start off dry, but conditions will start changing in the afternoon, thanks to a low-pressure system in the U.S. and a cold front from the northwest moving into the region. Rain will spread into central areas in the afternoon, reaching the GTA and eastern Ontario in the evening.
There will a smattering of storm risk with this setup, the only possible severe risk will be around Windsor around dinner time. The storms then head to Sarnia, London, and Goderich.
During the overnight hours and pre-dawn Wednesday, it looks like clusters of storms will head to the GTA. Those storms could include frequent lightning, heavy rainfall and gusty winds.
Tuesday also sees the return of the humidity, such that though daytime highs won't actually be much higher than these last two temperate days, they'll feel considerably warmer -- more like the low to mid-30s across much of the south.
Wednesday will feature similar temperatures and daytime highs, along with some risk for thunderstorms.
Thursday features still more of these conditions but also looks to mark the end of the streak. Friday sees a cold front descend through the province, bringing temperatures back down and sweeping away the humidity.
Beyond, the Labour Day weekend looks to start off mild and clear.
