Thunderstorm watches for parts of the region on Wednesday
Wednesday will be hot and steamy to start off, with a mix of sun and cloud mid morning with a chance of showers and thunderstorms as a cold front starts to move in.
"The winds gusting in advance of that front, out of the southwest, 30 [km/h] with gusts to 50 km/h, it's going to be extremely hot and humid into the afternoon. It's gong to feel like the mid-30s," said CTV News London meteorologist Julie Atchison.
There is the chance of showers and thunderstorms any time throughout the day on Wednesday as the front approaches with lots of instability across southern Ontario.
"Any time a front comes through and you have an air mass that is this hot and humid, there is the potential for thunderstorms to develop. So heading into the afternoon we could still see some active weather as the front pushes off to the east,"
The normal daytime high for this time of year is around 20 C and the low around 9 C.
