Coastal “June gloom” in October is expected to continue through the weekend, with the marine layer gradually shrinking, according to the National Weather Service office in San Diego.
“Expect a gradual shallowing trend with the marine layer through the weekend,” the weather service said Thursday.
Temperatures through the weekend will be in the lower to mid 70s along the coast, lower to mid 80s in the valleys, upper 70s in the mountains and mid 90s in the deserts.
“Slow and slight warming will continue for coastal and valley locations through Saturday,” the weather service said. “A general cooling trend will then follow through the middle of next week as the upper-air pattern shifts.”
The agency said isolated to scattered thunderstorms are possible over the mountains through much of this weekend and into early next week.
