Flash Flood — Lyon, NV

Jul 18, 2023

Ample mid and upper level moisture that streamed across western Nevada, coupled with summer daytime heating, increased instability across the region that allowed for increased shower and thunderstorm chances (15-30%) that extended mostly south of US-50 from southern Mono County through Mineral counties. These storms were forecast to be a hybrid variety capable of gusty outflow winds up to 50 mph, heavy rainfall, and isolated dry strikes outside of storm cores.
