DISCUSSION
THE CURRENT WEATHER PATTERN CONTINUES OVER THE NEXT 5 TO 7 DAYS WITH
LITTLE TO NO CHANGE. HIGH PRESSURE PREVAILS, MAINTAINING ONSHORE

MPH IN THE AFTERNOON, ESPECIALLY BEHIND THE INLAND-MOVING SEA
BREEZE. MOISTURE GRADUALLY INCREASES THIS WEEKEND INTO EARLY NEXT

TO VERY GOOD DISPERSION IS FORECAST LATE WEEK INTO THE WEEKEND.
FOG POTENTIAL...WIDESPREAD FOG IS NOT FORECAST. LOCALIZED VISIBILITY
