A subtle mid-level short wave trough will exit the Great Basin into the Northern Rockies this afternoon. Mid-level flow and surface pressure gradients will relax across the Great Basin as the trough ejects northeastward through the day although resulting in sustained west-southwest surface winds around 10-15 mph during peak boundary layer mixing. However, locally elevated fire weather conditions, particularly leeward of mountain ranges within the Great Basin and northwestern Arizona and southwest Utah, can be expected today. Stronger winds of 15-25 mph are likely across the upper Snake River Plain but fuels are not as receptive to wildfire spread as regions farther south. ..Williams.. 06/26/2025 .PREV DISCUSSION... /ISSUED 1248 AM CDT Thu Jun 26 2025/ ...Synopsis... Fire weather concerns are expected to remain limited for today across the country. Widespread rainfall over the eastern two-thirds of the country will limit fuel status for most locations. West of the Rockies, dry conditions will continue with afternoon RH minimums in the teens expected. However, the strongest low/mid-level flow is expected to remain across the Pacific Northwest (where RH reductions won`t be as pronounced) ahead of a low-amplitude mid-level trough. Localized elevated conditions may materialize across portions of southern ID and northern NV where the overlap of dry conditions, receptive fuels, and modest surface winds (15-20 mph) is most probable. Latest high-res ensemble guidance generally shows a weak signal for widespread and/or persistent elevated conditions, which limits confidence in the overall fire weather threat. ...Please see www.spc.noaa.gov/fire for graphic product... $$
