DISCUSSION

(This afternoon through Friday)

WEATHER PATTERN OVERVIEW: An upper-level area of high pressure will remain over the Southeastern United States today. Southerly flow should keep monsoonal moisture streaming northward into Eastern Nevada today, resulting in isolated to scattered thunderstorms this afternoon into this evening. A few of these thunderstorms could be strong. The primary thunderstorm hazards will be erratic wind gusts near 50 mph and dangerous cloud to ground lightning strikes. There is a marginal risk (5-15%) of excessive rainfall in Southern White Pine and Eastern Nye Counties this afternoon into this evening. Heavy rainfall may result in flooding of recent burn scars.

The aforementioned anticyclone aloft will progressive retrograde westward Sunday through Friday. As a result, the flow should shift from southerly to southwesterly, pushing monsoonal moisture eastward. There is an elevated risk of wildfires in Humboldt County Monday afternoon into Monday evening due to southwest wind gusts near 25 mph and minimum relative humidity values as low as 12 percent. A warming trend is expected Sunday through Thursday. By Thursday afternoon, high temperatures across Northern and Central Nevada will be two to four degrees above normal for this time of year. High temperatures will remain above seasonal values Friday. Here are probabilities of maximum temperatures of 90 degrees or higher for select locations in Northern and Central Nevada on Thursday, August 20th, 2026:

Battle Mountain - 96% Elko - 95% Winnemucca - 95% West Wendover - 95% Carlin - 95% Tonopah - 90% Wells - 90% Spring Creek - 85% Eureka - 85% Ely - 70%
