Tuesday, July 9th 2019, 8:45 pm - Eyes on a Thursday thunderstorm threat for southern Ontario
Southern Ontario as spent the first part of the week swathed in near-perfect summer weather, under sunny skies, seasonal temperatures, and only modest humidity. Sticky conditions are on their way back into the region, however, and that may put a damper of the latter half of the week. More on the timing of the next round of showers and thunderstorms, plus a look at the next stretch of hot and humid weather, below.

BUILDING HEAT AND HUMIDITY WEDNESDAY
Wednesday will be the hottest day of the week as temperatures approach the 30°C mark across most of the south with increasing humidity making things feel closer to the high 30s -- enough to be uncomfortable for some, but not as sticky as it was last week.
Still, with that building heat and humidity comes a chance for thunderstorms ahead of a return to widespread storms and showers as a system tracks through the Great Lakes region on Thursday.
Any storms that do erupt Wednesday afternoon will be very scattered in nature; many places won't see any rain at all. The best chance looks to be over cottage country and in eastern Ontario in the late afternoon and evening hours.
STRONG STORMS THREATEN FOR THURSDAY
A system moving through Thursday will make for a more definite precipitation pattern, however, with showers and storms expected to sweep through much of southern and central Ontario through the day.
Multiple rounds of rain are likely Thursday, but the strong to severe storm threat comes with the cold front, which is expected to cut through starting in the mid-to-late afternoon in southwestern Ontario and continuing through the evening hours in the east.
