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.
