An upper low that stalled offshore the California coast injected inland as an open short wave trough and brought an increased chance for showers to the Sierra and Western Nevada. A subsequently stronger, more dynamic, upper shortwave and attendant cold front dropped south and southwest into the region and brought enhanced, more organized bands of shower activity, lower snow-levels, and breezy south-southwest winds. This resulted in some  travel impacts to higher Sierra passes.
