..DISCUSSION FROM MONTEREY
 
 
ONSHORE FLOW INCREASES FOR SUNDAY, CAUSING MUCH COOLER CONDTIONS. AN  
ONCOMING COLD FRONT WILL CAUSE BREEZY AND GUSTY WINDS SUNDAY  
AFTERNOON. THE FRONT WILL ALSO OFFER CHANCES FOR LIGHT SHOWERS  
STARTING IN THE LATE AFTERNOON AND LINGERING INTO THE NIGHT. EXPECT  
COOL CONDITONS TO LAST FOR NEXT WEEK AND EVEN MORE CHANCES FOR RAIN  
STARTING IN THE MID WEEK.  
 
NOTE : ALL WINDS ARE 20-FOOT WINDS UNLESS OTHERWISE SPECIFIED.  
THUNDERSTORMS IMPLY STRONG, GUSTY AND ERRATIC WINDS.
