An upper-level trough will begin to sag into northern California and the northern Great Basin today. A surface trough will develop from the Northwest into the central Great Basin. Elevated to locally critical conditions are possible from northern Nevada into the Snake River Plain and western Wyoming. RH will be lowest in Nevada where 10-20% is expected. Farther north and east, 15-20% will be more common. Surface wind speeds will generally range from 15-20 mph in most locations. With some terrain enhancement in the Snake River Plain, there is some potential for briefly stronger winds. This location has a greater probability for sustained critical conditions, though ensemble guidance continues to suggest it will remain quite localized. ..Wendt.. 07/20/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
