Southern California Warm Spell Begins to Ease as Offshore Winds Subside

Overview

• High pressure keeps Sunday and Monday temperatures well above normal, with many valleys and coastal areas in the 70s to low 80s and mountains mostly in the 50s to 60s.
• Offshore flow is weakening into Monday morning with earlier wind advisories dropped, though inland and mountain areas still report gusts near 30 to 40 mph.
• A shallow marine layer and patchy fog could briefly return at the immediate coast late Sunday into early Monday before drier offshore air redevelops Monday night into Tuesday.
• Temperatures cool gradually from Tuesday through Thursday as the upper ridge weakens and onshore influence increases.
• Forecast models show a possible late-week system that would bring more clouds, further cooling and low rain chances, but the track and impacts remain uncertain.
