A midlevel trough will continue eastward across the Northwest and northern Rockies during the day -- where ample midlevel moisture will remain in place atop a diurnally deepening boundary layer. Related forcing for ascent preceding the trough will promote isolated to widely scattered fast-moving thunderstorms across parts of the northern Rockies and Northwest during the afternoon and early evening. Given 0.7-0.9 inch PW, a dry/well-mixed boundary layer, and fast storm motions, a mix of wet/dry thunderstorms will pose a risk of lightning-induced ignitions and gusty/erratic outflow winds atop receptive fuels. Additionally, enhanced deep-layer west-southwesterly flow accompanying the midlevel trough will overspread the warm/dry air mass in place across the northern Rockies, yielding dry/breezy (elevated) fire-weather conditions during the afternoon. Farther south, dry/breezy southerly return flow will develop across parts of the southern High Plains -- in response to a passing low-amplitude midlevel trough. These dry/breezy conditions atop increasingly receptive fuels will favor elevated fire-weather conditions during the afternoon. ..Weinman.. 08/22/2026 ...Please see www.spc.noaa.gov/fire for graphic product... $$
