SYNOPSIS
STRONG HIGH PRESSURE CENTERED OFF THE NEW ENGLAND COAST WILL
CONTINUE TO WEDGE DOWN THE SOUTHEASTERN SEABOARD THROUGH THIS
EVENING BEFORE THIS FEATURE SHIFTS FURTHER OFFSHORE IN ADVANCE OF
AN APPROACHING COLD FRONT LATER TONIGHT. DENSE SEA FOG WILL
CONTINUE THROUGH AT LEAST THE LATE AFTERNOON HOURS FOR THE NEAR
SHORE WATERS ADJACENT TO SOUTHEAST GEORGIA. SOUTHWESTERLY WINDS
WILL GRADUALLY STRENGTHEN ON SATURDAY NIGHT AHEAD OF THE
APPROACHING COLD FRONT, WITH WINDS SHIFTING TO WESTERLY AND
INCREASING TO CAUTION LEVELS ON SUNDAY MORNING AS THE FRONT
CROSSES OUR LOCAL WATERS. SCATTERED SHOWERS WILL ACCOMPANY THE
FRONTAL PASSAGE, WITH WINDS THEN SHIFTING TO NORTHWESTERLY AND
INCREASING TO SMALL CRAFT ADVISORY LEVELS ON SUNDAY AFTERNOON AND
NIGHT. SMALL CRAFT ADVISORY CONDITIONS WILL LIKELY CONTINUE ON
MONDAY AS WINDS SHIFT TO NORTH-NORTHEASTERLY DUE TO HIGH PRESSURE
BUILDING OVER THE TENNESSEE AND LOWER MISSISSIPPI VALLEYS. HIGH
PRESSURE WILL THEN GRADUALLY WEAKEN OVER THE SOUTHEASTERN STATES
ON MONDAY NIGHT AND TUESDAY, ALLOWING WINDS TO SHIFT TO
NORTHEASTERLY WHILE GRADUALLY DIMINISHING. SHOWERS MAY DEVELOP ON
TUESDAY NIGHT AND WEDNESDAY WELL IN ADVANCE OF ANOTHER COLD FRONT
THAT WILL BE ENTERING THE SOUTHEASTERN STATES.
