Southern California Warmth Begins to Ease as Weak System Approaches Late Week

Overview

• Monday stays mild to warm, with highs around the upper 60s to mid-70s at the coast, mid-70s to low 80s inland, upper 50s to 60s in the mountains, and mid to upper 70s in the deserts.
• Offshore Santa Ana winds remain gusty in inland and mountain areas, with easterly gusts commonly 20–45 mph and recent peaks near 30–40 mph, before easing by midweek.
• Temperatures trend downward from Tuesday through Thursday as the high-pressure ridge weakens and clouds increase, especially by Wednesday.
• A late-week low carries only a slight chance of light showers, with most spots—if any rain falls—likely near a tenth of an inch or less and track and timing still uncertain.
• Brief marine-layer intrusions could bring patchy dense fog to the immediate coast during morning and evening hours, though offshore flow often keeps low clouds offshore.
