Night and morning low clouds are likely to continue across the San Diego County coast and valleys each day this week, with minimal clearing expected for the coast, the National Weather Service said.

“There will be a cooling trend through Friday with the marine layer deepening onto the coastal slopes of the mountains,” the agency said.

Morning drizzle is possible along the coast, while thunderstorms could develop across the mountains and deserts.

Highs Monday will be 66 to 69 near the coast, 70 inland, 71 to 74 in the western valleys, 77 to 82 near the foothills, 77 to 87 in the mountains and 99 to 104 in the deserts.

The weather service said warming next weekend could dispel the recent “June gloom” conditions.
