KEY MESSAGE 1: MOISTURE INCREASES HEADING INTO THE WEEKEND AND
INTO NEXT WEEK, BRINGING RAIN CHANCES BACK TO THE AREA.
AN UPPER RIDGE REMAINS OVER THE SOUTHEAST EARLY THIS MORNING.
MEANWHILE, AN UPPER LOW IS DEVELOPING OFF THE SOUTHEAST COAST.
THE RIDGE IS FORECAST TO RETROGRADE WESTWARD, DRIVEN BY THE
UPPER LOW MOVING WESTWARD OVER FLORIDA AND INTO THE GULF. THIS
WILL LEAVE OUR AREA ON THE PERIPHERY OF THE UPPER RIDGE. AS IT
DOES, MOISTURE IS EXPECTED TO SLOWLY INCREASE THROUGH THE DAY
THURSDAY BEFORE RAMPING UP FRIDAY AN INTO THE WEEKEND. ENERGY
MOVING AROUND THE AFOREMENTIONED UPPER RIDGE BRINGS INCREASED
CHANCES FOR SHOWERS AND THUNDERSTORMS BEGINNING FRIDAY AFTERNOON

LINGERS. A RELATIVE LULL IN ACTIVITY REMAINS POSSIBLE FOR
SUNDAY. AS FAR AS TEMPERATURES GO, A GRADUAL WARMING TREND IS
FORECAST TO CONTINUE TODAY INTO TOMORROW BEFORE RETURNING TO
