A DEEPENING MARINE LAYER BROUGHT SOME RELIEF TO THE COAST TODAY  
WHILE INLAND AREAS REMAIN HOT AND DRY. THE MARINE LAYER WILL  
CONTINUE TO DEEPEN TONIGHT TO AROUND 1200 FEET RESULTING IN FARTHER  
INLAND INTRUSION OF THE LOW CLOUDS AND GOOD HUMIDITY RECOVERY IN  
THE VALLEYS. AREAS FARTHER INLAND AND ABOVE THE MARINE LAYER WILL  
CONTINUE TO STAY HOT AND DRY WITH ONLY MODERATE HUMIDITY RECOVERY.  
TEMPERATURES WILL TREND COOLER THROUGH THE WEEKEND AS THE MARINE  
LAYER DEEPENS AND ONSHORE FLOW PERSISTS. SEASONABLE TEMPERATURES  
ARE EXPECTED THROUGH THE WEEKEND AND INTO EARLY NEXT WEEK.  
 
NOTE : ALL WINDS ARE 20-FOOT WINDS UNLESS OTHERWISE SPECIFIED.  
THUNDERSTORMS IMPLY STRONG, GUSTY AND ERRATIC WINDS.
