Broad midlevel troughing will persist across the Northwest/Intermountain West, while an expansive midlevel anticyclone builds over the Southwest and southern/central Rockies. ...Great Basin into the central/northern Rockies... Between the expansive midlevel anticyclone and broad midlevel troughing, a belt of enhanced deep-layer west-southwesterly flow will persist across the Great Basin into the northern/central Rockies. Diurnal heating amid a dry antecedent air mass will yield a deeply mixed boundary layer (single-digit to lower teens RH). These dry conditions combined with 15-20 mph sustained west-southwesterly surface winds will lead to widespread elevated fire-weather conditions, with critical conditions expected over southern/central UT into northern AZ (where the overlap of strong winds and low RH atop receptive fuels will be maximized). ..Weinman.. 08/04/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
