This weekend's weather will not be mentioned in the next San Diego Chamber of Commerce brochure, but it won't be all that bad either, the National Weather Service said Thursday.
An upper-level low-pressure system will make it noticeably cooler--with the typical late-night and early-morning low clouds--at least through Monday, said Wilbur Shigehara, a National Weather Service forecaster.
The clouds will probably cling along the beach area through most of the day this weekend, and may cause some morning drizzle, he said. Temperatures in the coastal areas will be seasonal, with daytime highs about 68 degrees. The nighttime temperature will be about 57 degrees.
The inland valleys will also experience night and morning cloudiness, although there is a greater possibility for afternoon clearing in those areas. Daytime temperatures will be in the low 70s through Sunday. Nighttime temperatures will be about 50 degrees.
Although the coastal mountain slopes will also experience some cloudiness, the mountain areas in East San Diego County will be fair through Monday, Shigehara said. Daytime temperatures will be 58 to 68 degrees, with nighttime temperatures dropping to the 31- to 41-degree range.
The cooling trend should reach the desert, dropping typical 100-degree temperatures down to the low 90s. Overnight lows in the desert will be about 65.
