Event narrative

NV Energy site at Wild Oat Mountain located 1.0 mi SSE of Holbrook Junction, NV, reported 24 hour storm total rainfall amount of 0.85 inches.

Wider weather episode

An upper level low that moved inland the afternoon and evening of the 18th brought increased rain, snow above 8500 feet, and thunder chances to the region on the 19th. Higher resolution ensemble simulations also continued to project chances for showers and isolated thunderstorms across the Sierra, the Sierra Front and vicinity as the upper low swung southeast towards southern Nevada. The best dynamics with this system remained mostly northward of the low pressure center with a jet streak located in the vicinity of the Eastern Sierra. High-Resolution Rapid Response guidance consistently showed concurrence with this scenario. Differences noted in ensemble simulations, however, lead to some uncertainty with the intensity of shower activity. Therefore, the expected intensities would range between light to moderate rainfall with isolated areas of heavy rainfall. Simulations showed that Mono County and the Eastern Sierra would have the best chances for higher elevation snowfall above 8500 with blended guidance showing a 20-50% chance for storm total snow greater than 4 inches.
