Cooler weather persists through the weekend, with a deeper, more persistent marine layer and night and morning coastal low clouds extending well inland and onto the coastal slopes of the mountains. Southwest to west winds for the mountains and deserts will gust to 40 to 50 mph through Sunday, with isolated gusts to 65 mph. Gradually warmer, dry weather with generally weak winds will follow Monday through Thursday, followed by a slight cooldown from Thursday into Friday.
For extreme southwestern California including Orange, San Diego, western Riverside and southwestern San Bernardino counties,
(today through tomorrow night), Gusty winds will continue through the day today and through this evening as low pressure brings winds from the west over the area. As low pressure shifts further east, winds will ease through Monday. Strongest winds are in the deserts, desert mountain slopes and mountain passes with gusts up to 45 to 55 mph, locally up to 60 mph.
Highs today and Monday will be near to just below average for much of the area. The exception being some areas in the Riverside and San Bernardino county mountains with highs 5 to 10 degrees below average.
Low clouds from the marine layers influence will stick around through the day today and are expected to clear Monday morning.
(Tuesday through Sunday), As winds shift to off shore Tuesday, low clouds will stick closer to the coast, giving us some much needed sunshine in the afternoons at least through mid-week. Temperatures increase area wide Tuesday, with daily highs continuing to increase through the week, peaking Thursday afternoon. Temperatures Thursday will be up to 5 degrees warmer than average over most of the area. The high deserts will see temperatures 5-10 degrees above average.
171800z, Coast/Valleys, SCT-BKN clouds with bases 2000+ ft MSL through the coastal basin. Low clouds should scatter out through 20z, although some may linger in inland valleys through the afternoon. Low confidence in timing of cigs developing along the coast, higher confidence that when cigs develop bases will be 2000- 3000 ft MSL. Elevated N/NE winds may prevent cigs from developing at KONT/KSBD/KSNA. Highest chances of cigs at KSNA are 30-40 percent 04- 12Z Mon. Low clouds will scatter 16-18Z from the valleys to the coast.
Mountains/Deserts, Gusty north to northwest winds with widespread 30-40 knot surface gusts expected in the deserts, locally up 60 knots in vulnerable mountain passes such as the San Gorgonio Pass. MOD up/downdrafts and local LLWS in lee of mountains as well as localized VIS reductions to 4-6SM expected, especially during periods of strong gusts. Winds weaken after 10z Mon.
Elevated seas will continue to diminish into the afternoon. No hazardous marine conditions expected Monday through Friday.
A westerly swell from 290 degrees with a 9 to 10 second period is bringing elevated surf of 4 to 6 feet through Monday morning. Highest surf on west to northwest facing beaches. The combination of elevated surf and high tides of 6.5 to 7 feet will result in minor tidal overflow, especially for beach parking lots and boardwalks. Surf will start to decrease Monday afternoon.
Ca, Beach Hazards Statement through Monday morning for Orange County Coastal Areas-San Diego County Coastal Areas.
Wind Advisory until 3 AM PDT Monday for Apple and Lucerne Valleys-Riverside County Mountains-San Bernardino County Mountains-San Diego County Deserts-San Diego County Mountains-San Gorgonio Pass near Banning.
PZ, None.
