A WEAKNESS IN THE UPPER RIDGE COMBINED WITH ONSHORE FLOW AND DIURNAL HEATING WILL LEAD TO THE DEVELOPMENT AND MAINTENANCE OF SCATTERED SHOWERS AND THUNDERSTORMS EVEN AFTER THE LOSS OF DIURNAL HEATING. A BRIEF BREAK IN THE WET PATTERN IS EXPECTED ON FRIDAY AS THE LOW LEVEL FLOW BECOMES WESTERLY AND ONLY ISOLATED THUNDERSTORMS WILL BE POSSIBLE. HIGHS WILL BE WITHIN A FEW DEGREES OF 80. A CUT OFF UPPER LOW IS FORECAST BY THE MODELS TO APPROACH NC SATURDAY THEN DRIFT SE ACROSS THE AREA ON SUNDAY. THE UPPER SYSTEM IN COMBINATION WITH A SURFACE FRONT AND DEVELOPING TRIPLE POINT LOW WILL BRING A GOOD CHANCE FOR SCATTERED SHOWERS AND THUNDERSTORMS TO EASTERN NC SATURDAY AND SUNDAY.

AS OF 300 PM TUESDAY...UNSETTLED WEATHER EXPECTED THROUGH MUCH OF THE PERIOD. THE EARLY MORNINGS THROUGH FRIDAY WILL BE PRONE TO FOG AND STRATUS DEVELOPMENT.
