AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
426 PM EDT SAT APR 14 2007
.SHORT TERM /REST OF TONIGHT/...
AN WILL UPDATE TO THE ZONES WILL INCLUDE A LAKE WIND ADVISORY FOR
TONIGHT. WINDS OF 15 TO 25 MPH WITH GUSTS TO 35 MPH ARE EXPECTED
IN WESTERN NC...AND THE MOUTNAINS OF NORTHEAST GA AND SC...AHEAD
OF THE APPROACHING SURFACE WAVE.
&&
.PREV DISCUSSION...
/ISSUED 316 PM EDT SAT APR 14 2007/
SHORT TERM /TONIGHT THROUGH TUESDAY/...
SURFACE LOW SUPPORTED BY STRONG UPPER DPVA WIL MOVE ACROSS THE
REGION OVERNIGHT. DESPITE THE CLOSENESS OF THE EVENT...STILL SOME
RATHER LARGE DISCONTINUITIES IN THE DETAILS BETWEEN THE 12Z GFS/NAM.
NAM IS FARTHER NORTH WITH SURFACE LOW AND SUBSEQUENTLY DEVELOPS MUCH
MORE INSTABILITY OVER THE REGION THROUGH THE OVERNIGHT AND A SLOWER
PROGRESSION OF COLD FRONT. GFS A LITTLE FARTHER SOUTH WITH LOW TRACK
AND FASTER...SO CONSEQUENTLY THE DEWPOINTS/INSTABILITY NOT AS HIGH.
WILL SETTLE ON A BLEND OF THESE SOLUTIONS WHICH PUTS NE
GEORGIA...UPSTATE SC AND THE NC PIEDMONT UNDER THE GUN FOR SEVERE
STORMS. WIND PROFILES INDICATE PLENTY OF SHEAR...SO A FEW TORNADOES
POSSIBLY ASSOCIATED WITH A QUASI-LINEAR CONVECTIVE SYSTEM CANT BE
RULED OUT. HEAVY RAIN ALSO IS A GOOD BET FOR ABOUT A 6 HOUR WINDOW.
WIDESPREAD 1-2 INCHES IS LIKELY OVERNIGHT WITH SOME 2+ INCHES
POSSIBLE. PER HPC GUIDANCE THIS AXIS OF HEAVIEST RAINFALL WOULD NOSE
UP INTO NC PIEDMONT AND FOOTHILLS. PER COLLABORATION WITH NEIGHBORS
WILL PUT UP A FLOOD WATCH FOR THE NC PIEDMONT AND FOOTHILLS. EXPECT
THAT METRO CHARLOTTE WILL CERTAINLY HAVE SOME FLOOD ISSUES. STRONG
LOW LEVEL JET WILL PUNCH INTO THE AREA IN ADVANCE OF THE SURFACE
LOW...SO HAVE INCREASED WINDS AND PLACED GUSTS TO 30-40 MPH IN THE
GRIDS FOR A FEW HOURS.
LOW AND ASSOCIATED WIDESPREAD RAIN/THUNDERSTORMS WILL EXIT TO THE
EAST EARLY SUNDAY. PROBABLY WILL BE A LULL IN SHOWERS FOR A FEW
HOURS SUNDAY MORNING. AS STRONG UPPER TROUGH AND COLD POOL TRANSITS
THE AREA MIDDAY TO MID AFTERNOON. EXPECT SHOWERS TO DEVELOP
AGAIN...MOST NUMEROUS FOR THE MOUNTAINS AND EASTERN PART OF THE
UPSTATE AND NC PIEDMONT. THUNDERSTORMS ALSO A GOOD BET OUTSIDE OF
THE MOUNTAINS ALONG WITH SMALL HAIL. SNOW LEVELS WILL CRASH IN THE
MOUNTAINS SUNDAY AFTERNOON WITH PASSAGE OF UPPER TROUGH...SO WILL
FORECAST SNOW SHOWERS ABOVE 2500FT BY LATE AFTERNOON ALONG WITH
FALLING TEMPERATURES. STRONG WINDS WIL ALSO BEGIN TO MIX DOWN BY
LATE IN THE DAY WITH >50MPH IN THE MOUNTAINS AND 30-40MPH OUTSIDE OF
MOUNTAINS.
A NORTHWEST FLOW SNOW AND WIND EVENT IS IN STORE FOR THE MOUNTAINS
SUNDAY NIGHT AND MONDAY BEHIND THE DEPARTING SURFACE WAVE AND ITS
ASSOCIATED SHORTWAVE ROUNDING THE UPPER LOW. MODEL THICKNESS AND
SOUNDINGS SUPPORT ALL SNOW SUNDAY NIGHT AND MONDAY MORNING...EXCEPT
AT THE VERY LOWEST VALLEY ELEVATIONS...WITH MOISTURE ALL THE WAY
DOWN THE TENNESSEE BORDER. AT THIS POINT THE BEST ACCUMULATIONS WILL
BE IN THE NORTHERN MOUNTAINS...WHERE AMOUNTS SUPPORT WARNING
CRITERIA. SNOW AMOUNTS COULD APPROACH WARNING CRITERIA IN THE SMOKY
MOUNTAINS...BUT CONFIDENCE IS NOT AS HIGH THAT FAR SOUTH. THE WIND
WILL ALSO BE AN ISSUE...WITH THE MODELS CARRYING 60 KNOTS OF WIND AT
850 MB OVER A BROAD AREA SUNDAY NIGHT AND MONDAY. MOIST SOIL
RESULTING FROM THE RAINFALL TONIGHT WILL ALLOW TREES TO BE EASILY
TOPPLED...MEANING DAMAGE POTENTIAL MAY REPLACE WIND SPEED CRITERIA.
CONFIDENCE IS HIGH ENOUGH ON WIND AND SNOW IN THE NORTHERN MOUNTAINS
THAT A WINTER STORM WARNING WILL BE ISSUED FOR SUNDAY AFTERNOON
THROUGH MONDAY FROM AVERY TO MADISON COUNTIES IN THE NC MOUNTAINS. A
HIGH WIND WATCH WILL BE ISSUED FOR THE REST OF THE MOUNTAINS...AS
WELL AS THE ADJACENT NC FOOTHILLS...EVEN THROUGH WINDS MAY BE BELOW
WARNING CRITERIA IN SOME PORTIONS OF THE WATCH.
MOISTURE DECREASES RAPIDLY SUNDAY AFTERNOON...WHILE THICKNESS AND
TEMPERATURES RISE...ENDING THE SNOW EVENT. THE HIGH WINDS MAY WELL
CONTINUE INTO MONDAY NIGHT...AND MAYBE EVEN TUESDAY MORNING...BUT
CONFIDENCE IS LOWER AT THAT TIME FRAME. TEMPERATURES WILL BE COOL
ENOUGH FOR A FREEZE WATCH IN THE NC MOUNTAINS MONDAY MORNING...AND
ANOTHER NIGHT OF FREEZING TEMPERATURES IS SCHEDULED FOR TUESDAY
MORNING...HOWEVER LOCAL POLICY IS NOT TO ISSUE FREEZE PRODUCTS WHEN
WINTER WEATHER IS FORECAST. AFTERNOON MAXIMUM TEMPERATURES WILL
RECOVER WITH DOWNSLOPE FLOW AND RISING HEIGHTS ALOFT.
LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
AN UPPER LEVEL OMEGA BLOCK DOMINATES THE PATTERN OVER NORTH AMERICA
FOR MOST OF THE EXTENDED FORECAST...WITH THE SOUTHERN APPALACHIANS
ON THE BACK SIDE OF THE DOWNSTREAM UPPER LOW...IN A MEAN NORTHWEST
FLOW ALOFT. A WEAK CLIPPER LIKE SYSTEM CROSSES THE AREA FROM THE
WEST ON WEDNESDAY...SUPPORTING LITTLE MORE THAN SLIGHT CHANCE
POPS...WHILE A BETTER DEFINED LOW ORGANIZES IN THE NORTHWEST GULF.
THE GULF LOW CROSSES NORTH FL THURSDAY...FAR ENOUGH SOUTH THAT POPS
WILL BE LIMITED...BUT WITH AN EASTERLY UPSLOPE COMPONENT NORTH OF
THE LOW...CHANCE POPS WILL BE CARRIED ALONG THE BLUE RIDGE
ESCARPMENT. A DRY SURFACE RIDGE WILL MOVE SLOWLY EAST OVER THE AREA
ON FRIDAY AND SATURDAY. TEMPERATURES WILL GRADUALLY MODERATE FROM
BELOW NORMAL TOWARD NORMAL AS THE OMEGA BLOCK WEAKENS AND HEIGHTS
RISE.
AVIATION /19Z-18Z/...
TAFS WILL BECOME QUITE COMPLICATED OVERNIGHT AS LOW PRESSURE TRACKS
ACROSS THE REGION. CURRENTLY VFR WITH ONLY MID LEVEL CLOUDS.
HOWEVER...EXPECT RAIN AND SCATTERED THUNDERSTORMS TO SPREAD RAPIDLY
WEST TO EAST ACROSS THE AREA FROM 22Z-02Z. WITH THE ONSET OF THE
RAIN...EXPECT CEILINGS TO RAPIDLY LOWER INTO THE MVFR RANGE. A 4-6
HOUR PERIOD OF HEAVY RAIN EXPECTED FROM ABOUT 03-09Z WITH EMBEDDED
THUNDERSTROMS WHICH SHOULD LOWER CEILINGS INTO IFR CATEGORY.
WIDESPREAD PRECIPITATION SHOULD MOVE EAST OF THE AREA IN 08Z-12Z
TIMEFRAME WITH CELINGS BUMPING UP INTO MVFR RANGE WITH VFR CELINGS
LIKELY BY 14Z-16Z SUNDAY. SHOWERS EXPECTED TO REDEVELOP MIDDAY
SUNDAY AS UPPER TROUGH SWINGS THROUGH. COULD EVEN HAVE SOME
THUNDERSTORMS OUTSIDE OF THE MOUNTAINS.
VISIBILITIES WILL LOWER TO IFR RANGE IN THE HEAVIER RAIN OVERNIGHT
AND THEN BOUNCE BACK TO VFR 09Z-12Z TIMEFRAME.
