Cooler weather and a chance of rain are predicted Monday for San Diego County, with a deeper marine layer and gusty westerly winds, the National Weather Service said.
The marine layer should be sufficient to generate some sprinkles across the coastal basin Monday night into early Tuesday, and possibly again Tuesday night, with minimal accumulations expected, the NWS said.
Cooling was expected to intensify Monday and Tuesday in response to a low-pressure system developing over the northern Great Basin, the weather service said.
“This could enhance onshore flow across the region, bringing gusty winds to desert slopes and passes Monday through Wednesday — strongest Tuesday — and a deeper marine layer,” forecasters said.
Thursday was expected to see a return to a warming trend that will continue into the weekend, with more shallow marine layer clouds each night and morning at the coast, the NWS said.
High temperatures Monday are expected to reach 64 near the coast, 65 to 70 inland, 69 to 74 in the valleys, 67 to 77 in the mountains and 89 to 94 in the deserts.
