THE REGION WILL BE BETWEEN HIGH PRESSURE OVER THE GULF, AND A
TROUGH TO THE NORTH NORTHEAST TODAY. THE TROUGH WILL MOVE
OFFSHORE TONIGHT. THE PASSAGE OF THE TROUGH IS EXPECTED TO BE DRY.
HIGH PRESSURE WILL BUILD TO THE NORTH WEDNESDAY NIGHT, AND TO THE
NORTHEAST THURSDAY.
FOG AND STRATUS IS EXPECTED TO DEVELOP UNDER THE RIDGE OVER THE
NORTHEASTERN GULF THIS MORNING, AND ADVECT EAST OVER THE SUWANNEE
VALLEY. THE BEST CHANCE FOR FOG THIS MORNING WILL BE ALONG AND WEST
OF THE I75 CORRIDOR. THE AFTERNOON IS EXPECTED TO BE MOSTLY SUNNY
ACROSS THE AREA. FOR TONIGHT, RIDGING OVERHEAD, THE FOG AND STRATUS
IS EXPECTED TO BECOME MORE WIDESPREAD. ONCE THE FOG LIFTS, ANOTHER
MAINLY SUNNY DAY FORECAST FOR THURSDAY.

TODAY. HIGHS TODAY WILL RANGE FROM THE UPPER 60S OVER INTERIOR
SE GA, TO LOWER 70S ELSEWHERE. LOWS TONIGHT IN THE MIDDLE TO UPPER
40S WILL BE COMMON. WITH THE POSITION OF THE HIGH, THE FLOW WILL
