SYNOPSIS
HIGH PRESSURE BUILDING OVER THE GREAT LAKES REGION WILL WEDGE DOWN
THE SOUTHEASTERN SEABOARD THROUGH FRIDAY, CREATING BREEZY
NORTHEASTERLY WINDS ACROSS OUR LOCAL WATERS. ELEVATED SEAS OFFSHORE

FRIDAY MORNING. CAUTION CONDITIONS WILL PREVAIL FOR THE NEAR SHORE
WATERS ADJACENT TO NORTHEAST FLORIDA THROUGH AT LEAST FRIDAY. HIGH
PRESSURE WILL THEN WEAKEN AS IT SHIFTS SOUTHEASTWARD TOWARDS OUR
LOCAL WATERS ON SATURDAY, ALLOWING WINDS AND SEAS TO DIMINISH. A
WEAKENING COLD FRONT WILL THEN APPROACH OUR REGION ON SUNDAY NIGHT,
POSSIBLY DEVELOPING A FEW SHOWERS AND THUNDERSTORMS AHEAD OF IT.
SOUTHWESTERLY WINDS WILL BRIEFLY STRENGTHEN AHEAD OF THIS BOUNDARY,
WITH WINDS SHIFTING TO NORTHERLY IN THE WAKE OF THIS FRONTAL PASSAGE
