A cooling trend in San Diego County was forecast through Tuesday as low pressure deepens over the western United States, the National Weather Service said.
“The cooling trend will continue through Tuesday as low pressure deepens over the western states,” the weather service said. “Night and morning low clouds will again only partially clear along and west of the mountains.”
High temperatures along the coast Monday are predicted to reach 67 degrees, 68 in the western valleys, 62 to 67 near the foothills, 57 to 65 in the mountains and 82 to 87 in the deserts, according to the weather agency.
Strong winds were forecast for the region, especially in the mountains and deserts Monday afternoon through early Tuesday.
A cold front should move through Monday night, with the possibility of light rain. Any precipitation was expected to be less than a tenth of an inch. Little or no snow was predicted in the mountains.
It was forecast to be chilly Tuesday with temperatures 5-15 degrees below average, with most mountain areas seeing highs in the 40s, and the lower deserts getting into the 70s, the weather service said.
“Tuesday will be quite cool and breezy, with more seasonal weather expected for the
remainder of the week as temperatures slowly moderate,” the agency said.
Dry conditions were expected starting Tuesday with little or no marine layer.
Northwest winds were expected over coastal waters Monday and Tuesday, with gale force winds coming Monday afternoon through Tuesday morning, forecasters said. Gusts near 35 knots and combined seas of 8-12 feet were possible.
A gale watch remains in effect for the inner and outer waters from late Monday afternoon through early Tuesday. Winds were forecast to gust 20-30 knots for much of Tuesday, weakening Tuesday night.
