Extended Heat Wave Begins Today 🔥
A heat wave will begin across portions of the state today, with high temperatures in the low to mid 90’s expected across portions of Central and all of Southern Illinois.
While hot temperatures are expected, heat indices will stay in check today, running at levels not too much higher than the actual temperature.
This heat wave will continue through much of this upcoming week across the southern half of the state, perhaps flexing into the northern half of the state at times.
