Tropical moisture from Hurricane Priscilla is making its way through the desert southwest this afternoon, mainly east of our area. However, there remains around a 5 percent probability for thunderstorms in the eastern portions of the Kern County Desert. Cloud-to-ground lightning, locally intense rainfall rates, gusty and erratic winds, and small hail are possible in developed storms.

A low pressure system currently located off the Pacific Northwest coast is expected to move into the western US over the weekend, bringing stronger wind gusts to the lee side of the mountain areas of central California Saturday. There is over a 90 percent probability for maximum wind gusts to exceed 40 mph along CA Highway 14 and US Highway 395 and in the Mojave Slopes during this time frame.

A relatively cold Pacific storm is expected to bring precipitation from late Monday until at least the middle of next week. Here are probabilities for at least 0.25 inch of rainfall for select locations in the Central Valley.

A relatively cold Pacific storm will arrive late Monday and bring chances of precipitation until at least the middle of next week. Here are the latest probabilities for at least 0.50 inch of rain for select locations in the Sierra Nevada foothills.

The first significant snow of the season is expected in the higher elevations of the Sierra Nevada above 7,000 feet by Tuesday. Here are the latest probabilities for at least 3 inches of snow in a 24 hour period. While there are lower chances for higher amounts, it is not out of the question for snow totals to reach a foot at some locations in the higher elevations of the Sierra Nevada during Tuesday-Wednesday.
