An unexpectedly heavy marine layer brought drizzle and cooler temperatures to San Diego on Saturday, and a similar forecast is in store for Sunday.
“Expect patchy drizzle and light rain to continue through the morning hours, with little to no clearing of the marine layer clouds expected again today,” the National Weather Service said in its Sunday morning forecast.
The unusual weather is due to a low-pressure system “parked” off the coast of California through at least Tuesday.
“This cool and gloomy pattern won’t be going anywhere fast,” the weather service said.
It will be sunny in the mountains and deserts, but 5 to 10 degrees cooler than normal.
Highs on Sunday are forecast to be 69 to 73 along the coast, 72 to 77 in the western valleys, 76 to 86 in the mountains and 96 to 99 in the deserts.
