Marginally cooler weather was predicted Sunday for San Diego County, with an expansive shield of high clouds, 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.
