Showers and isolated thunderstorms could hit the San Diego County coast late today as a fall storm moves inland, forecasters said.
The eastward-moving, low-pressure system is expected to bring numerous showers and scattered thunderstorms throughout the county all day Thursday, according to the National Weather Service. The rain should let up Thursday night into early Friday, with a possibility of just a few lingering showers in the mountains Friday afternoon, according to the agency.
General rainfall amounts are expected to range from a quarter-inch near the coast to an inch in the mountains. In the deserts, less than a quarter-inch is expected.
The storm is expected to cause temperatures to drop around 10 degrees below average in the mountains at lower elevations and about 20 degrees below average at higher elevations and in inland valleys.
"This is a sharp contrast to early last week when high temperatures were 10 to 15 degrees above average,'' noted an NWS advisory.
The snow level Thursday could drop to between 6,500 and 7,000 feet, with a few inches of snowfall possible on the higher peaks, mainly above 7,000 feet, according to the Weather Service.
Highs today are expected to peak in the high 60s to low 70s in coastal and valley areas, 60s in the mountains and mid-80s in the deserts.
