About the Program

The NWS Office in Green Bay issues Terminal Aerodrome Forecasts (TAF) for four airports in northeast Wisconsin: Green Bay (KGRB), Appleton (KATW), Manitowoc (KMTW), Wausau (KAUW), Mosinee (KCWA), and Rhinelander (KRHI).  A TAF is also issued for Oshkosh (KOSH) during the late July/early August period.

These site-specific forecasts detail weather changes out to 24 hours, and include forecasts of ceilings and cloud heights, wind speed and direction, weather and obstructions to visibility, and low-level wind shear. The forecasts are issued four times a day and are updated as needed.
