...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).
