Cooler weather, chance of rain on Thanksgiving

SAN DIEGO – The San Diego area will experience a cooling trend this week, a period marked by a deepening marine layer along the coast, increasing winds inland and a chance of Thanksgiving rain, forecasters said Monday.

A low-pressure system moving over the county is expected to usher in a mild dip in local temperatures through Friday, with thermometer readings falling from the low 70s to the mid-60s, according to the National Weather Service.

Light precipitation will be possible Wednesday night into Thursday afternoon, meteorologists advised. Amounts are expected to range from around one-tenth of an inch to around a third of an inch of moisture across the region,

Over the period, gusty west to southwest winds will develop in the mountains and deserts, forecasters said.

A second unsettled atmospheric system could bring more gentle showers Friday night and Saturday before making way for a return of dry conditions and warmer days next week, the NWS reported.
