A cold low pressure system dropped southwestward from the northern Rocky Mountain region through the Great Basin on May 9 and into central California by the morning of May 10 which destabilized the airmass over the area and produced showers and thunderstorms across the area. This low then slowly moved southward through central California during the morning of May 10 which resulted in locally heavy rainfall over Tulare and Kern Counties. Precipitation amounts varied due to the convective nature of the precipitation. A few locations over the higher elevations in Tulare and Kern County picked up over an inch of rainfall. Most locations in the San Joaquin Valley picked up less than a quarter inch of rainfall although several stations in the Bakersfield area picked up between a quarter inch and a half inch of rain. The most noticeable impacts from the thunderstorms were several reports of roadway flooding in the Bakersfield area which led to some brief road closures, and some reports of nuisance flooding and small hail in the mountains and Kern County Deserts. Some light snow fell over the higher elevations of the Southern Sierra Nevada with several stations above 8000 feet picking up between 3 and 6 inches.
