While mid-level winds will steadily weaken across the Great Basin today, enough flow across the Sierra and strong heating in Nevada will promote a weak surface trough in northern Nevada. This feature will drive downslope winds into parts of southern and central Nevada. Winds around 15 to perhaps 20 mph will occur in a confined zone. RH will fall to 10-15% by the afternoon. Local, marginally critical conditions may occur very briefly as well. A few hours of elevated fire weather is expected. ..Wendt.. 07/22/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
