centered off the West Coast will draw moisture from the remnants of weakening Hurricane Priscilla northward into the area, increasing chances for showers and thunderstorms. The greater chances for heavier rainfall are from the mountains of San Bernardino, Riverside, and San Diego Counties eastward across the deserts into Arizona with decreasing chances toward the west. Higher-resolution model guidance shows bands of showers with a slight chance of thunderstorms moving northwestward across the area on Thursday morning with additional chances for showers and thunderstorms during the afternoon more focused over the mountains eastward across the deserts. Chances for showers and thunderstorms will continue at times through Friday into Friday evening. NBM chances for one inch or more of rainfall is around 5 percent for the mountains. However, the HRRR does show the potential for 6-hourly rainfall to around 1.5 inch for portions of the mountains and deserts for Thursday afternoon. $$ 17
