Valid 251200Z - 261200Z

...Synopsis...
Along the northwestern periphery of an expansive large-scale ridge
centered on the southern Rockies, a low-amplitude shortwave trough
will overspread the northern Great Basin into the northern Rockies.
Associated large-scale forcing for ascent and sufficient midlevel
moisture/instability will support isolated high-based thunderstorms
across parts of central/northern ID and southwestern MT during the
afternoon. Around 0.5-0.75 inch PW and 20-30 mph northeastward storm
motions will favor dry thunderstorms capable of producing
lightning-induced ignitions atop receptive fuels.

Additionally, enhanced deep-layer south-southwesterly flow
accompanying the midlevel trough will promote 15-20 mph sustained
southwesterly surface winds amid 15-20 percent RH across parts of
the northern Great Basin and vicinity during the afternoon. As a
result, elevated fire-weather conditions are expected, given very
dry fuels (90th-95th percentile ERCs).
