Key Messages
- A stalling cold front creates a sharp temperature split Sunday, with highs ranging from the upper 70s northwest of the Illinois River to near 90 south of I-70. Scattered showers (20-40% chance) will be near the front.
- Multiple rounds of thunderstorms track along a stalled front Tuesday and Wednesday, especially north of I-72. There will be a low risk for strong to severe storms and locally heavy rain.
- Periodic thunderstorm chances persist Thursday and Friday along the lingering front...
