SYNOPSIS. Dry weather will continue today with temperatures a little below normal. A slow moving storm system will bring cooler conditions and precipitation Tuesday afternoon through Thursday. There is a slight chance of thunderstorms Wednesday afternoon and evening, mainly across the San Joaquin Valley. Dry weather along with a warming trend are likely Friday into the weekend.
DISCUSSION. Satellite loops are showing areas of low clouds across the Tehachapi Mountains, the Sierra Nevada foothills, and portions of the San Joaquin Valley. Expect some dissipation of these clouds with daytime heating but not completely; leaving a mix of sun/clouds through the afternoon. Some gusty conditions are occurring in the typical wind prone areas of the Kern County mountains but are generally expected to remain below advisory criteria today. Temperatures will be a few degrees below normal today, especially in areas that see more clouds than sun.
A cold low pressure system will move slowly southward off the Pacific Northwest coast through Tuesday. Precipitation will begin from the north Tuesday afternoon and should reach Kern County Tuesday night. Widespread precipitation is likely on Wednesday as the upper low moves over northern/central California. There is a slight chance of thunderstorms Wednesday afternoon/evening as the colder air aloft brings increased instability. Showers will likely continue on Thursday, mainly over the mountains, as the low wobbles over southern California. Good model agreement with the low shifting east over Arizona on Friday with just isolated light Sierra showers possible. Snow levels will start out around 4000 feet then lower to near 3000 feet Tuesday night. A Winter Storm Watch has been issued for the Sierra Nevada and adjacent foothills above 3000 feet from Tuesday afternoon thru Wednesday evening. 3 to 9 inches of snow will be possible in the foothills above 3000 feet and 9 to 18 inches of snow will be possible in the Sierra Nevada above 4000 feet. Snow is forecast to impact the major highway passes in the Kern County mountains too. Therefore, a Winter Storm Watch has been issued for the Tehachapi and Fort Tejon zones above 3000 feet, including the Grapevine along I-5, from Tuesday evening through Thursday afternoon. Between 2 to 6 inches of snow is possible above 3000 feet, and 6 to 10 inches possible above 4000 feet.
Beginning to see better model agreement in the extended with the low continuing to exit to the east this weekend as ridging nudges over the coast. Thus, dry weather and a warming trend are on tap for next weekend with high temperatures forecast to be near normal for mid March.
