Fire Weather Planning Forecast for Central/Southeast Illinois
National Weather Service Lincoln IL
238 AM CDT Sat Oct 18 2025

.DISCUSSION...

Scattered showers and thunderstorms will occur across central and
southeast Illinois today...with showers becoming most numerous
along and east of I-55 from mid-afternoon through tonight. Light
showers will linger into Sunday morning before dry weather returns
by afternoon. Ventilation will remain poor today. Once a cold front
passes, rising mixing heights and NW winds gusting over 30mph will
lead to much improved ventilation on Sunday.
