The return of the marine layer could result in 5 to 10 degrees of cooling to areas west of the mountains, and there may be a few pockets of drizzle in the coastal areas early Monday morning.
“A low pressure system moving southeastward through the Great Basin will bring deepening of the marine layer and cooling for the coast and valleys,” the weather service said.

Highs Monday were forecast to be around 63 near the coast, 66 to 69 inland, 68 to 72 in the western valleys, 71 to 76 near the foothills, 71 to 81 in the mountains and around 95 in the deserts.
A ridge of high pressure building over the West Coast was likely to bring a return of warmer days Tuesday through next weekend, the weather service said. The ridge may reduce the marine layer depth and weaken the onshore flow, which will keep the marine layer clouds and fog confined to the coastal areas.
By Thursday, daytime highs were predicted to warm into the upper 70s and low 80s in the San Diego valleys.
Coastal high temperatures may only be a few degrees above seasonal averages, while farther inland, the high temperatures may be 10 to 15 degrees above seasonal averages.
Thursday was likely be the warmest day of the week, especially west of the mountains.
Later in the week, there was some weakening of the ridge expected with the resulting moderating of temperatures, mainly west of the mountains.
No hazardous marine weather was expected through Thursday.
