.AVIATION /00Z FRIDAY THROUGH TUESDAY/... 
AS OF 1020 PM THURSDAY...

TAFS HAVE BEEN AMMENDED TO REFLECT A SLOWER PROGRESSION OF A FRONTAL 
PASSAGE AND SUBSEQUENT WEATHER CONDITIONS OUTLINED BELOW.  

VFR CONDITIONS WILL PREVAIL IN ADVANCE OF A COLD FRONT THAT WILL 
MOVE SOUTHEAST ACROSS CENTRAL NC TONIGHT...WITH TIMING THROUGH INT 
AND GSO BETWEEN 05-08Z; RDU AND RWI BETWEEN 08-10Z; AND FAY BETWEEN 
10-13Z. THE PASSAGE OF THE FRONT WILL RESULT IN A SHARP WIND SHIFT 
FROM SSW TO NW AND BE ACCOMPANIED BY A NARROW BAND OF LOW-TOPPED 
SHOWERS (AND POSSIBLY AN ISOLATED THUNDERSTORM) WITH GUSTY NW WINDS. 
POST-FRONTAL RAIN AND MVFR-IFR CONDITIONS WILL FOLLOW THE FRONT... 
THOUGH IT MAY TAKE SEVERAL HOURS BEHIND THE FRONT FOR ANY SUCH SUB-
VFR CONDITIONS TO BECOME PREVAILING CONDITIONS. WINDS WILL THEN 
GRADUALLY VEER TO A MORE NORTHERLY TO NORTHEASTERLY COMPONENT 
BETWEEN 12-18Z...AT WHICH TIME BLUSTERY SUSTAINED WINDS AND GUSTS 
WILL BE PROBABLE - HIGHEST AT EASTERN TAF SITES. RAIN WILL END FROM 
WEST TO EAST AFTER 18Z FRI...WITH AN ACCOMPANYING IMPROVEMENT IN 
FLIGHT CATEGORY TO MVFR...OR LIFTING AND SCATTERING TO VFR...BY LATE 
AFTERNOON - SLOWEST AT EASTERN TERMINALS.  

OUTLOOK: A BRIEF PERIOD OF SUB-VFR CONDITIONS MAY REDEVELOP WITH THE 
PASSAGE OF AN UPPER LEVEL DISTURBANCE FRI NIGHT...PARTICULARLY AT 
EASTERN TAF SITES. OTHERWISE...THERE WILL BE A THREAT OF MVFR 
CEILINGS WITH THE PASSAGE OF ANOTHER COLD FRONT SUN NIGHT.
