Fall To Begin On A Cool Note Across San Diego County

SAN DIEGO, CA — Below-average temperatures were expected in San Diego County for much of this week before a gradual warming into next weekend, the National Weather Service said Sunday.

Low clouds filled in the coastal basin overnight, sneaking into portions of the Cajon and San Gorgonio passes. The cloud deck was starting to break up and mostly sunny skies were expected for the majority of the area by Sunday afternoon.

Gusty west winds from Saturday night and Sunday morning peaked at 35 to 45 mph.

Periods of gusty west winds were expected each afternoon and early evening through mid-week, forecasters said. Dry conditions were predicted to continue with night and morning low clouds.

High temperatures along the coast Sunday were predicted to be in the mid-70s with overnight lows of around 60. Highs in the valleys were expected to be in the upper 70s with lows in the mid-50s. Highs in the mountains were expected to be in the mid-70s with lows in the lower 50s and highs in the deserts were predicted to be in the mid-90s with lows in the upper 60s.

A trough along the West Coast was expected to be the main influence on San Diego County's weather as a low-pressure system slowly makes its way inland before moving off to the northeast Thursday.

The pattern was predicted to bring below-average temperatures and periods of gusty west winds in the afternoons and evenings through Wednesday.

The strongest winds were expected below passes and on desert mountain slopes with peak gusts of 35 to 45 mph, the NWS said. Marine layer low clouds were predicted each night and morning.

Some degree of warming for the end of the week was predicted into the weekend.

Periods of breezy northwest winds around 20 knots were possible over the coastal waters at times this week, most likely Tuesday and Wednesday during the afternoons and evenings.
