985 FNUS28 KWNS 042137 FWDD38 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0434 PM CDT Sat Oct 04 2025 Valid 061200Z - 121200Z ...Days 3-5/Monday-Wednesday... A mid-level trough will progress eastward from the Great Lakes region into the northeastern U.S. through midweek. An associated surface cold front and attendant rainfall will stretch across much of the Great Lakes into New England through the Day 5/Wednesday period, mitigating some fire weather concerns across much of the Ohio River Valley where very dry fuels and drought remain. A plume of deeper Gulf moisture from a tropical disturbance and attendant showers and thunderstorms moving northward will subdue fire weather concerns across the Lower Mississippi River Valley and Appalachians through midweek. West of the Divide, a gradual warming and drying trend will emerge as an elongated mid-level trough departs the region, although rather benign fuel conditions in the wake of recent cool and moist conditions will continue to limit fire weather threats across the West. ...Days 6-8/Thursday-Saturday... Ensemble cluster analysis reveals increasing uncertainty late in the week in terms of timing and magnitude of the next mid-level trough coming into the western U.S. Deeper moisture from tropical cyclone activity in the eastern Pacific could interact with the potential mid-latitude cyclone bringing more rain to the Desert Southwest, Great Basin and Intermountain West Days 7-8/Friday-Saturday. This would further subdue fire weather concerns across the region in addition to an unsupportive fuel environment. ..Williams.. 10/04/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
