316 PM EDT FRI JUN 23 2006

.SHORT TERM /TONIGHT THROUGH SATURDAY/...
THUNDERSTORMS HAVE ERUPTED ACROSS THE MOUNTAINS AND MUCH OF THE BLUE
RIDGE THIS AFTERNOON. AT LEAST LIKELY COVERAGE EXPECTED OVER THE
WESTERN SECTIONS...WITH SCATTERED TO THE SOUTH. WILL WATCH RADAR
TRENDS AND MAKE FINAL DECISION ON COVERAGE BEFORE ISSUANCE. MORE
SEVERE EXPECTED INTO THE EVENING EVEN WITH THE MOIST AIR MASS. CAPES
AS HIGH AS 4000 J/KG WITH SOME SPEED SHEAR. STORMS ARE MOVING MORE
TODAY WITH THE STRONGER WIND FLOW...HOWEVER THE NUMBER OF STORMS
COULD LEAD TO TRAINING. ISOLATED VERY HEAVY RAINFALL HAS ALREADY
OCCURRED...SO CANNOT RULE OUT SOME FLASH FLOODS. STORMS DIMINISH IN
STRENGTH AFTER SUNSET...BUT STORMS AND SHOWERS LINGER MUCH OF THE
NIGHT. RIDGE LINGERS TO OUR EAST AHEAD OF THE DEVELOPING COASTAL
SYSTEM...WITH TROF TO OUR WEST. MOIST UNSTABLE ATMOSPHERE CONTINUES
SATURDAY...SO ANOTHER ROUND OF STORMS EXPECTED. COVERAGE SHOULD BE
SIMILAR TO TODAY GIVEN THE UPPER AIR PATTERN. LIKELY WEST TO LOW
CHANCE SOUTH. SEVERE CHANCE LESS SATURDAY...BUT CANNOT BE RULED OUT.
VERY MILD NIGHT AGAIN TONIGHT...AND COOLER SATURDAY WITH MORE CLOUDS
AND LOWER THICKNESSES.

&&

.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
A SIGNIFICANT RAINFALL EVENT APPEARS LIKELY FOR OUR FORECAST AREA
SATURDAY NIGHT INTO MONDAY WITH A COMBINATION OF A SURFACE
BOUNDARY...TROPICAL MOISTURE AND PERSISTENT UPSLOPE FLOW. THERE WILL
ALSO BE SEVERAL UPPER DISTURBANCES ROTATING ACROSS THE REGION AS THE
UPPER RIDGE BREAKS DOWN AND A TROF EVOLVES OVER THE SOUTHEAST STATES.
IN ADDITION...THE GUIDANCE CONTINUES TO SHIFT A TROPICAL LOW
WESTWARD TOWARD THE SOUTHEAST STATES...THEN TREK IT TO THE NORTHEAST
ALONG THE COASTAL PLAIN...AND IF THAT HAPPENS...THERE COULD BE AN
ENHANCEMENT TO OUR UPSLOPE FLOW FOR LOCATIONS ALONG THE EASTERN
ESCARPMENT AND OTHER LOCATIONS WITH A SOUTHEAST ASPECT. THE TIME OF
HEAVIEST RAIN...AND GREATEST COVERAGE...APPEARS TO BE SHAPING UP FOR
SATURDAY NIGHT THROUGH SUNDAY NIGHT. WE FEATURE OUR HIGHEST CHANCES
OF RAIN THROUGH THE ENTIRE EVENT FOR THE SOUTHERN MOUNTAINS OF NORTH
CAROLINA AND THE SOUTH CAROLINA MOUNTAINS SUNDAY EVENING. THE HPC
5-DAY RAINFALL PROG INDICATES A WIDESPREAD 2 TO 4 INCH SWATH OF
PRECIPITATION FOR MOST OF THE FORECAST AREA.
WE PLAN TO ISSUE AN
EXCESSIVE RAINFALL OUTLOOK FOR THE WEEKEND COINCIDENT WITH THIS
PACKAGE.

&&

.AVIATION...
THUNDERSTORMS ERUPTING OVER THE MOUNTAINS WITH ONLY ISOLATED
ELSEWHERE RIGHT NOW. THUNDERSTORMS WILL LIKELY IMPACT ALL SITES AT
SOME POINT THIS AFTERNOON OR EVENING. LOW VFR LIKELY...BUT
CONDITIONS WILL BRIEFLY BE LOWER IF CENTER OF CELLS MOVE DIRECTLY
OVER THE SITE. STORMS WILL LINGER INTO THE EVENING...BUT SHOULD
DIMINISH IN COVERAGE AFTER SUNSET. EXPECT AT LEAST A BRIEF PERIOD OF
MVFR VISIBILITY ALL SITES NEAR SUNRISE. WHERE RAIN FALLS...LONGER
MVFR PERIOD WITH TEMPO IFR LIKELY. COULD EVEN BE SOME LOW CEILINGS
AT THESE LOCATIONS. VFR EXPECTED AFTER SUNRISE WITH CONVECTIVE
DEBRIS CEILINGS. MORE THUNDERSTORMS EXPECTED SATURDAY...BUT WILL
WAIT UNTIL THE 00Z TAFS TO ADDRESS THESE. LIGHT AND VARIABLE WINDS
THROUGH THE PERIOD EXCEPT VARIABLE AND GUSTY NEAR THUNDERSTORMS.

&&

.HYDROLOGY...
THUNDERSTORMS THIS EVENING WILL BE SLOW-MOVERS...CAPABLE OF
PRODUCING EXCESSIVE RAINFALL WHEREVER THEY FORM. STREAM AND WATER
LEVELS WILL NEED TO BE MONITORED CAREFULLY UNTIL CONVECTION
WEAKENS LATER TODAY. WE PLAN TO ISSUE AN EXCESSIVE RAINFALL
OUTLOOK FOR THE WEEKEND COINCIDENT WITH THIS PACKAGE.
