No changes were made for the Day 1 update with limited larger scale fire weather concerns across the contiguous U.S. Deep layer southwesterly flow ahead of an upper-level trough moving into the West along with a dry, well-mixed boundary layer will promote sustained southwest winds of up to 20 mph this afternoon across southern NV and western UT. Breezy southwest winds combined with RH as low as 15% will support localized elevated fire weather conditions but fuels remain subdued in supporting large fire growth, keeping the fire weather threat relatively low. ..Williams.. 10/02/2025 .PREV DISCUSSION... /ISSUED 1258 AM CDT Thu Oct 02 2025/ ...Synopsis... Fire weather concerns will remain limited for today across the country. A diffuse surface trough draped across the Plains will continue to weaken through the day, leading to modest winds across the Plains where fuels have been slowly drying in the absence of appreciable rainfall in recent days. An upper trough will begin moving onshore across the West, resulting in broad surface pressure falls across the Great Basin/Intermountain West. Latest model consensus suggests 15-20 mph winds are likely from southern NV into western UT with gusts around 25 mph possible. Mostly clear skies will promote sufficient heating/mixing for RH reductions into the teens, which will support scattered elevated fire weather conditions. Despite this uptick, ERCs remain depressed after widespread rainfall within the past week. As such, fire weather concerns will remain low. ...Please see www.spc.noaa.gov/fire for graphic product... $$
