An upper-level low along Pacific Northwest coast will promote a broad southwesterly flow across much of the West. South to southwest winds of 15-25 mph across much of NV, and southern ID will develop in response to daytime boundary layer mixing. However, a rapid northward surge of low-level moisture from the Desert Southwest will quickly suppress fire weather concerns across the southern Great Basin through the day. A narrow corridor of wind/RH alignment is still possible across portions of western NV, but continued northwest advancement of low-level moisture into the state and largely unreceptive fuels will mitigate a broader and longer duration fire weather threat. Otherwise, no changes to previous forecast (see below). ..Williams.. 10/08/2025 .PREV DISCUSSION... /ISSUED 0158 AM CDT Wed Oct 08 2025/ ...Synopsis... Upper ridging will persist across the central and southern CONUS as an upper trough lingers along the West Coast and a mid-level trough amplifies over the Upper Mississippi Valley tomorrow (Thursday). Surface high pressure east of the Mississippi River will encourage generally dry conditions, but with a weak surface wind field. Meanwhile, modest moisture return across the Upper Mississippi Valley will precede the aforementioned upper trough. Finally, isolated to potentially scattered thunderstorms are likely across the southwestern quadrant of the U.S. Overall, generally quiescent fire weather conditions are expected across the CONUS tomorrow (Thursday). ...Please see www.spc.noaa.gov/fire for graphic product... $$
