A low-pressure system sweeping into Southern California will produce light rain throughout San Diego County on Wednesday evening and continue into Thanksgiving Day.
The National Weather Service office in San Diego said the majority of the rainfall is expected late Wednesday evening and early Thursday morning.
Escondido and Oceanside are expected to receive around a quarter-inch of rainfall, while one-tenth of an inch is expected near the coast and in the western valleys. The mountains are forecast to get between a quarter-inch and one-third inch, and the deserts less than one-tenth of an inch.
High temperatures Wednesday will reach 70 degrees at the beaches and inland, 71 in the western valleys, 69 near the foothills, 65 in the mountains and 75 in the deserts.
A second unsettled atmospheric system could bring more gentle showers Friday night and Saturday before making way for a return of dry conditions and warmer days next week, the weather service said.
