DISCUSSION
KEY MESSAGE 1: MAINLY DRY CONDITIONS THROUGH THE MIDDLE OF NEXT
WEEK.
DRY HIGH PRESSURE WILL BUILD INTO THE AREA THROUGH FRIDAY, THEN
PUSH OFF THE SOUTHEAST COAST ON SATURDAY. MID-LEVEL HEIGHT
INCREASES AND SOUTHERLY FLOW OVER THE WEEKEND WILL RESULT IN
WARMING TEMPERATURES.
MOISTURE WILL GRADUALLY INCREASE TOWARD THE MIDDLE AND LATTER
PART OF NEXT WEEK. UPPER DISTURBANCES COULD BRING SOME SHOWERS
AND TSTMS WEDNESDAY INTO THURSDAY.
KEY MESSAGE 2: MINOR COASTAL FLOODING IS POSSIBLE ALONG PORTIONS
OF THE SOUTH CAROLINA COAST WITH EVENING HIGH TIDES THROUGH
TUESDAY.
ASTRONOMICAL TIDES WILL BE RISING DUE TO THE UPCOMING NEW MOON (ON
SATURDAY). IN FACT, THE CHARLESTON ASTRONOMICAL TIDE ALONE IS
EXPECTED TO PEAK JUST ABOVE 6.7 FT MLLW WITH THE SATURDAY AND SUNDAY
EVENING HIGH TIDES. THEREFORE, EVEN SMALL POSITIVE ANOMALIES COULD
LEAD TO MINOR COASTAL FLOODING FOR CHARLESTON AND COASTAL COLLETON
COUNTIES BOTH OF THOSE EVENINGS. THIS WILL ALL BE HIGHLY DEPENDENT
ON THE WIND DIRECTION THE NEXT FEW DAYS. OVERALL, EACH HIGH TIDE
THROUGH AT LEAST TUESDAY WILL NEED TO BE MONITORED FOR POTENTIAL
FLOODING.
