.AVIATION /06Z THURSDAY THROUGH MONDAY/... 
AS OF 1235 AM THURSDAY...

YET ANOTHER ROUND OF IFR/LIFR CONDITIONS WITH STRATUS AND FOG IS 
LIKELY TO DOMINATE THIS MORNING. WITH FAVORABLE CONDITIONS IN PLACE 
INCLUDING VERY LIGHT OR CALM WINDS AREAWIDE AND A LACK OF CLOUDS 
PROMOTING SURFACE COOLING DOWN TO THE DEWPOINTS... PATCHY DENSE FOG 
WITH VSBYS UNDER A HALF MILE IS LIKELY TO SPREAD AND FILL IN OVER 
NEARLY ALL OF CENTRAL NC EARLY IN THE TAF PERIOD. THESE ADVERSE 
AVIATION CONDITIONS ARE EXPECTED TO SLOWLY IMPROVE TO MVFR AT ALL 
SITES BETWEEN 13Z AND 15Z... AND TO VFR BY 17Z. RAIN CHANCES REMAIN 
VERY LOW AT CENTRAL NC TAF SITES... ALTHOUGH PASSAGE OF A WEAK UPPER 
LEVEL DISTURBANCE THIS MORNING COULD BRING AN ISOLATED SPRINKLE OR 
TWO TO RDU/RWI. AND ADDITIONAL ISOLATED VERY LIGHT (VFR) SHOWERS ARE 
POSSIBLE LATE THIS AFTERNOON ASSOCIATED WITH A WEAK WARM FRONT 
MOVING NORTHEASTWARD THROUGH THE AREA. WINDS WILL BE LARGELY CALM 
THROUGH MID MORNING... THEN REMAIN LIGHT/VARIABLE THIS AFTERNOON AND 
EVENING BUT PREDOMINANTLY FROM THE SE. PATCHY MVFR-IFR FOG MAY FORM 
ONCE AGAIN LATE IN THE TAF VALID PERIOD (AFTER 04Z FRI).

LOOKING BEYOND 06Z EARLY FRI MORNING... PATCHY FOG SHOULD HOLD 
THROUGH DAYBREAK FRI MORNING... FOLLOWED BY IMPROVEMENT TO VFR 
DURING MID-LATE FRI MORNING. A STRONG FRONTAL SYSTEM WILL BRING 
INCREASING SURFACE WINDS FROM THE SW AND A GOOD CHANCE OF SUB-VFR 
CONDITIONS IN WIDESPREAD SHOWERS AND A FEW STORMS FRI EVENING 
THROUGH FRI NIGHT... EXITING THE EASTERN TAFS EARLY SAT MORNING. VFR 
CONDITIONS SHOULD THEN RESUME SAT AFTERNOON... LASTING THROUGH 
MONDAY... AS HIGH PRESSURE BUILDS IN FROM THE WEST. -GIH
