AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
553 PM EDT MON APR 3 2006

.SHORT TERM /REST OF TONIGHT/...
UPDATE FORTHCOMING TO REMOVE ALL BUT THOSE COUNTIES ADJACENT TO
INTERSTATE 77 FROM THE TORNADO WATCH. WILL ALSO ISSUE UPDATE TO
MAKE THE TRANSITION FROM OUR MOUNTAIN WIND ADVISORY TO THE HIGH
WIND WARNING.

&&

.PREV DISCUSSION...
 /ISSUED 310 PM EDT MON APR 3 2006/

SHORT TERM /TONIGHT THROUGH THURSDAY/...
TORNADO WATCH 147 CONTINUES FOR MOST OF THE CWFA UNTIL 8 PM WITH THE
RISK FOR SVR STORMS CONTINUING JUST ALONG AND OUT AHEAD OF APPROACHING
COLD FRONT WHICH AS OF 19 UTC WAS NEARING THE SW NC MTNS. FROM MID-
EVENING ONWARD...THE PRIMARY CONCERN IS THE THREAT OF STRONG GRADIENT
WINDS AS THE COMBINATION OF A PERIOD OF SHARP CAA...STRONG SFC PRESSURE
RISES...A 50 KT 85H JET AND A 90 KT 50H JET PERPENDICULAR TO THE HIGHER
TERRAIN LEADS TO THE PROBABILITY OF DAMAGING WIND GUSTS. MODEL TIME
HEIGHTS THROUGH THE NORTHERN NC MTNS/FTHLS INDICATE A PERIOD OF DEEP
DOWNWARD OMEGA THIS EVENING...BUT MIXING IS LIMITED IN THE LOWER
TERRAIN...NOT SURPRISING GIVING THE TIME OF DAY. SO...BASED ON
THIS HAVE UPGRADED NC MTNS TO HIGH WIND WARNING AND ISSUED WARNING
AS WELL FOR NC FTHLS.

WINDS SHOULD DIMINISH RAPIDLY DURING THE DAY TUESDAY...BUT A
RESURGENCE IN 850 MB FLOW WILL BRING VERY WINDY CONDITIONS BACK
INTO THE SOUTHERN APPALACHIANS LATE TUESDAY NIGHT. THE INTENSE
UPPER LEVEL JET CORE WILL ALSO REMAIN OVER THE SRN APPALACHIANS
THROUGH TUESDAY NIGHT UNTIL UPPER RIDGING STARTS TO BUILD IN FROM
THE WEST. MODELS REVEAL SOME DEGREE OF MID LEVEL MOISTURE SPILLING
OVER THE RIDGE BY THURSDAY...AS A LOW LEVEL WARM FRONT LIFTS
NORTHEAST THROUGH THE TN VALLEY.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
DEEP LOW PRES MOVING EAST FROM THE CENTRAL PLAINS EARLY FRIDAY
SHOULD GRADUALLY GET ABSORBED BY THE ERN CANADIAN VORTEX OVER THE
WEEKEND. THIS WILL BRING A TROUGH AXIS ACROSS THE FORECAST AREA
MAINLY DURING SATURDAY. SLIGHTLY DEEPER MOISTURE AHEAD OF THIS WAVE
WILL AFFECT MAINLY MOUNTAIN LOCATIONS LATE FRIDAY INTO FRI
NIGHT...SPREADING SMALLER CHANCES THROUGH THE PIEDMONT INTO
SATURDAY. RESIDUAL NW FLOW MOISTURE MAY LINGER ALONG THE TN BORDER
THROUGH SAT NIGHT BEFORE DRYING. HIGH PRES WILL THEN REMAIN DOMINANT
ALONG THE SE COAST INTO EARLY NEXT WEEK.

AVIATION...
WILL GO WITH A SMATTERING OF VCTS FOR NOW FOR THE UPSTATE TAFS AND
KCLT AS DEEP CONVECTIVE DEVELOPMENT PERCOLATES INTO THE EARLY
EVENING HOURS. A GUSTY SW GRADIENT WIND CONCERN CONTINUES AS WELL
AHEAD OF APPROACHING COLD FRONT. EXPECT A GUSTY WIND SHIFT TO WEST
THEN NORTHWEST DURING THE EVENING HOURS IN THE IMMEDIATE
POST-FRONTAL AIRMASS. FOR THE OVERNIGHT HOURS...WILL KEEP GUSTY NW
WINDS CONFINED JUST TO KAVL AS CAA DIMINISHES ENOUGH TO REMOVE GUSTS
EAST OF THE MTNS.

FIRE WEATHER...
AFTERNOON RELATIVE HUMIDITY VALUES WILL FALL TO BETWEEN 20 AND 25
PERCENT IN ALL LOCATIONS BUT THE NORTHERN MOUNTAINS TUESDAY
AFTERNOON. SOME WINDY CONDITIONS WILL LINGER IN THE MORNING...BUT
WITH DIMINISHING WINDS THROUGH THE DAY...THE ONLY REAL THREAT FOR
RED FLAG APPEARS TO BE THE SOUTHERN AND CENTRAL MOUNTAINS OF NC. A
FIRE WEATHER WATCH MAY BE NEEDED FOLLOWING COORDINATION WITH
FORESTRY USERS.
