Forecasts


The Chicago/Romeoville National Weather Service Forecast Office issues generalized weather forecasts out to 7 days for north central and northeast Illinois and far northwest Indiana. Other offices (including Quad Cities, Lincoln, St. Louis and Paducah) issue forecasts for the remainder of Illinois and Indiana.

These forecasts are the product of a mix of scientific models and forecaster experience. The models run twice a day and so routine forecasts are issued in the early morning and mid afternoon (4 am and 4 pm). Updated forecasts are issued as conditions warrant.
