Fire Weather Planning Forecast For Northern IL and Northwest IN
National Weather Service Chicago/Romeoville IL
545 AM CDT Fri Aug 21 2026

.DISCUSSION...

Scattered showers and thunderstorms are expected this afternoon
and evening ahead of a cold front. A few storms could become
severe with damaging winds and large hail the main threats. Drier
conditions are expected this weekend into early next week,
however, there is a low chance (15-20%) for isolated showers and
storms Saturday afternoon. Otherwise, breezy north-northwest winds
gusting 20-30 mph are expected Saturday afternoon with gusts to
around 15-20 mph on Sunday. Mixing heights this weekend into early
next week are forecast to be around 4000-5000 ft with afternoon RH
values around 50-60%.

There is another chance for showers and thunderstorms towards the
middle of next week with another cold front. Though, confidence on
exact timing and coverage is low at this time.
