DISCUSSION

(Today through next Monday)

WEATHER PATTERN OVERVIEW: High temperatures throughout Northern Nevada Monday afternoon will be around five degrees above normal for this time of year. This will result in a moderate risk of heat-related illnesses.

The anticyclone aloft will move into the South Central United States Monday through Wednesday. This will push monsoonal moisture northward into most of Northern and Central Nevada, resulting in scattered showers and thunderstorms each afternoon and evening Monday through Wednesday. The primary thunderstorm hazards will be localized flooding, small hail, wind gusts near 45 mph, and dangerous cloud to ground lightning strikes. Here are thunderstorm probabilities for select locations in Eastern Nevada on Tuesday, July 21st, 2026:

Ely - 50% Lund - 50% Great Basin National Park - 50% Eureka - 48% Currie - 45% Ruby Lake - 43% Austin - 41% Elko - 36% Wells - 36% West Wendover - 31%

Monsoonal moisture should shift eastward Thursday and Friday, but lingering thunderstorm chances (slight) will remain in the service area forecast.

FORECAST CONFIDENCE & DEVIATIONS: High forecast confidence regarding a moderate risk of heat-related illnesses in Northern Nevada Monday afternoon. Moderate forecast confidence regarding a marginal risk of excessive rainfall in most of Northern and Central Nevada each afternoon and evening Monday through Wednesday. High forecast confidence regarding a few strong thunderstorms in most of Northern and Central Nevada each afternoon and evening today through at least Wednesday. No deviations from the NBM model output.
