The persistent high pressure over region began to break down on February 21, 2015, allowing a low pressure system to drop south into Central California on Sunday, February 22, directly over the San Joaquin Valley. The storm system lingered over the area through Monday, February 23. The storm brought showers and thunderstorms to the San Joaquin Valley and Sierra Foothills. The showers and
thunderstorms produced heavy rainfall across parts of Kern County where flood
advisories were issued due to ponding of water on roadways. These advisories included the south end of the San Joaquin Valley as well as the Kern County mountain and desert areas.
The upper level-low persisted until the 23rd, and wrap-around moisture flowed from the northeast into the east side of the San Joaquin Valley. Snow levels were fairly constant around 5000 feet over Kern and Tulare Counties during the 22nd-23rd. Around 5 to 10 inches of snow fell over the mountains of Kern and Tulare Counties, mainly during the afternoon of the 22nd and into the morning of the 23rd, and mainly above 6000 feet. A few snow showers persisted over the Sierra Nevada into the afternoon of the 23rd with a few locations in the high Sierra receiving 12 to 20 inches of snow over the two days. In addition, some instability showers and isolated thunderstorms developed in western Kern County around midday on the 23rd. One of the thunderstorms produced a brief weak tornado to the southwest of Belridge, or northwest of Taft, in the hills of the Temblor Range facing the southwestern San Joaquin Valley. There were reports of small hail about 0.25 inch in diameter reported with these thunderstorms.
Storm total rainfall amounts during the 22nd-23rd were around 0.5 to one inch over the San Joaquin Valley from Fresno southward, up to one inch of rain fell in the desert areas, and around 1 to 1.5 inches (with some locally higher amounts) fell over the southern Sierra Nevada and adjacent foothills mainly below 5000 feet. The Tehachapi Mountains received around one quarter to one-half inch of rain, including a few inches of snow above 5000 feet.
