SAN DIEGO -
Light rain fell around San Diego County Wednesday as a fall storm began its move inland a little earlier than expected.
The eastward-moving, low-pressure system was originally expected to start bringing numerous showers and scattered thunderstorms to coastal areas late tonight but light rainfall was occurring by this morning's commute, according to the National Weather Service.
The rain should increase in intensity and last throughout the day Thursday, letting up 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 Wednesday 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.
