(WSIL) -- At the risk of sounding like a broken record, this weekend will be hot and humid, with a chance of afternoon thunderstorms.
These thunderstorms will be driven by the afternoon heat, and be focused in places like southeast Missouri, and western Kentucky where the moisture is best. Southern Illinois will likely see a few storms develop, but chances will diminish northward towards Mt. Vernon and I-64.
Overall it's going to be a partly cloudy day with heat index values nearing 100 degrees this afternoon.
I'll have more details on News 3 at 6 a.m. and meteorologist Jacie Brianne will also be back tonight, with an update on your forecast.
