PEORIA (Heart of Illinois ABC) - Good Monday morning and happy 4th of July! Active conditions are in store for the start of the week as showers and thunderstorms return to the forecast. First Alert Weather Days have been issued for Monday and Tuesday as the potential for severe weather arrives followed by dangerous heat.

Monday: It’ll be a warm and muggy 4th across the Heart of Illinois as temperatures reach the upper 80′s for daytime highs. Factor in humid conditions and heat index values will reach the upper 90′s. Some areas may flirt with triple digit heat indices this afternoon.

The main focus for the 4th; however, will be the potential for a few strong to severe storms. A warm front slide through the region during the afternoon into the evening, driving our storm chances. Storms will pass from the west to east, with our westernmost counties seeing storms as early as lunchtime. Areas to the east of the Illinois River will see storm chances increase mainly after 2 PM. Our overall severe weather window will run from noon until 6 PM. With Monday being the 4th, make sure to keep an eye on the sky if you plan on being outdoors. The good news? We’ll be dry in time for fireworks tonight!

Strong to severe storms will be possible this afternoon, with the best potential north of I-74.
