Fire Weather Planning Forecast for Central/Southeast Illinois
National Weather Service Lincoln IL
217 PM CST Tue Dec 9 2025

.DISCUSSION...

A few rain showers (30-50% coverage) will impact central IL this
evening, followed by snow showers tomorrow behind a cold front.
Winds will blow from the southwest ahead of that front, but veer
sharply to northwest behind it with gusts of 40-50 mph during the
morning hours. Those winds will ease throughout the afternoon, with
another round of light snow during the evening possible (30%
chance). Despite shallow mixing heights, the strong northwesterly
transport winds tomorrow will result in good ventilation.
