NEW ZONE PACKAGE AND ASSOCIATED MATRIX PRODUCTS HAVE BEEN UPDATED
TO REFLECT ISSUANCE OF SEVERE THUNDERSTORM WATCH 135...IN EFFECT
UNTIL MIDNIGHT FOR THE FAR WESTERN 3 NORTH CAROLINA COUNTIES.

&&

.PREV DISCUSSION...
 /ISSUED 254 PM EDT SUN APR 2 2006/

SHORT TERM /TODAY THROUGH MONDAY/...
SHORTWAVE TROUGH TO DIVE INTO TN VALLEY TONIGHT...CROSSING AREA
MON. WARM FRONT TO LIFT NE ACROSS AREA THIS EVENING...DIRECTING
SCATTERED CONVECTION E ACROSS AREA. LAPSE RATES STEEP ENOUGH FOR
CONCERN ABOUT SEVERE THUNDERSTORMS...AND HAVE OUTLOOKED ENTIRE
AREA...ESPECIALLY MTS. COLD FRONT APPROACHES MTS TOWARD
DAWN...WHEN MODEL HAVE BEST OMEGA...BUT GUIDANCE POPS NOTABLY
BELOW LIKELY...AND HAVE CUT BACK TO HIGH CHANCE IN W WITH LOW
CHANCE IN E. WINDS TO INCREASE IN WARM SECTOR AHEAD OF COLD FRONT
TONIGHT AS GRADIENT TIGHTENS. WILL ISSUE LAKE WIND ADVISORY NC MTS
MIDNIGHT UNTIL 6 AM.

AS FRONT MOVES ACROSS AREA MON...BEST CHANCE OF PRECIPITATION SHIFTS
TO E PORTION OF AREA. UPPER LEVEL DIVERGENCE RATHER STRONG AND CAPE
BECOMES RATHER LARGE IN E...SO ANOTHER DAY OF SEVERE THUNDERSTORM
CONCERN...THIS TIME MAINLY I-77. BY LATE AFTERNOON POPS DROP IN
FOOTHILLS WITH DRYING BEHIND FRONT...WHILE MOISTURE ACCOMPANYING
UPPER SYSTEM REACHES N NC MTS IN UPSLOPE FLOW...SUPPORTING INCREASED
CHANCE OF SHOWERS. WIND TO COME UP AHEAD OF FRONT ALMOST ENTIRE AREA
MON AFTERNOON...GRADUALLY SHIFTING WITH FROPA BEFORE EVENING...AND
WIND OF ADVISORY CRITERIA MAY BE POSSIBLE IN NC MTS.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
STRONG FROPA EARLY MONDAY NIGHT. GOOD COLD ADVECTION AND H8 WNDS
OF 40 TO 50 KTS WL LIKELY RESULT IN WIND ADVISORY CONDITIONS IN
THE NRN MTNS...AND POSSIBLY INTO THE SRN AND CENTRAL MTNS AS WELL.
NAM HAS QUITE A BIT OF NW FLOW MOISTURE BANKED UP AGAINST THE
MTNS. BUFKIT AND AWIPS SOUNDINGS IMPLY THAT THERE COULD BE SOME
FREEZING DRIZZLE BETWEEN ABOUT 1500 AND 4000 FEET LATER AT NIGHT.
WON/T CARRY THAT NOW AS CONFIDENCE IS STILL A LITTLE LOW...BUT ITS
WORTH WATCHING.

WINDY IN THE MTNS AND BREEZY ELSEWHERE ON TUE...THOUGH WITH THE
AMOUNT OF H5 ENERGY OVER THE GREAT LAKES STATES AND NEW
ENGLAND...WNDS MAY VERIFY STRONGER...ESPECIALLY IN THE NC ZONES. MAX
TEMPS ARE IN LINE WITH GUIDANCE...WITH HIGHS IN THE 60S MOST
FOOTHILLS AND PIEDMONT LOCATIONS. SOME MTN RIDGETOPS PROBABLY
WON/T MAKE IT OUT OF THE 40S ON TUE WITH STEEP LAPSE RATES IN
PLACE.

WITH H5 UPPER LOW SLOWLY PUSHING OFF THE NEW ENGLAND COAST WED
MORNING...SFC RIDGE WL BEGIN TO BUILD INTO THE REGION. THE NAM IS A
LITTLE MORE PROGRESSIVE WITH THE UPPER LOW...AND THEREFORE CENTERS
THE SFC HIGH JUST ABOUT ON TOP OF THE SRN APPALACHIANS EARLY WED.
CONSIDERING THE DRY AIRMASS AND GOOD RADIATIONAL COOLING THIS WOULD
AFFORD...A FROST OR EVEN A FREEZE WOULD BE A GOOD BET FOR THE NC
FOOTHILLS AND PIEDMONT...AND POSSIBLY FOR THE UPSTATE AND NE GA. IF
THE GFS IS RIGHT...MIXING WL BE STRONGER WITH THE CHANCES OF A
FROST/FREEZE NOT AS GOOD. FOR NOW INCLUDED PATCHY FROST IN THE
NON-MTN ZONES WHERE THE LOW IS 36 OR LESS.

LATEST GFS HAS COME MUCH MORE INTO LINE WITH THE 00 UTC RUN OF
THE ECMWF. THIS SOLUTION IS SLOWER WITH THE NEXT UPPER LOW THAT
MOVES OUR WAY. WITH H8 TEMPS WARMING TO AROUND +14 DEG C THU AND
FRI AHEAD OF THE LOW...MAX TEMPS LOOK TO BE AT LEAST IN THE 70S IF
NOT 80S THOSE TWO DAYS. HAVE INCLUDED A LOW CHANCE POP FRI AND
SAT AS THE UPPER LOW MOVES ACROSS THE REGION. NOT SURE HOW MUCH
MOISTURE THIS WAVE WL TAP AS IT DOESN/T LOOK TO BE OF SUFFICIENT
AMPLITUDE TO REALLY TAP THE GULF. DRY AND STILL MILD ON SUNDAY.

AVIATION...
CONVECTIVE ACTIVITY MOVING INTO SW NC MTS TO DIMINISH AS IT PASSES
BETWEEN KAVL AND KAND...WHERE VCSH WIL BE CARRIED. ACTIVITY MAY NOT
MAKE IT AS FAR E AS KGSP/KGMU. EXPECT SCT LOW CLOUDS TO DEVELOP THIS
AFTERNOON AS WARM FRONT LIFTS N BRINGING LOW LEVEL MOISTURE TO
AREA...WITH SOME HIGH ALTOCUMULUS LEFTOVER FROM CONVECTION IN MTS.
WIND STAY UP OUT OF SW TONIGHT...BUT WITH SLIGHT VEERING...KAVL
WIND SHOULD TURN FROM S TO NW...LOCKING IN LOW VFR CIG OVERNIGHT.
EXPECT LOW MVFR CIGS SC TAF SITES AS WELL WITH MOISTURE BETWEEN
WARM AND COLD FRONTS. BEST LOW LEVEL MOISTURE MOVES NE TO NC
PIEDMONT BY MORNING...SHIFTING FOCUS OF LOW VFR CIGS FROM SC
SITES...TO KHKY/KCLT. BY LATE MORNING...WIND SHOULD COME UP AS
GRADIENT TIGHTENS AHEAD OF APPROACHING SURFACE LOW.

FIRE WEATHER...
DEWPOINTS MIX OUT INTO THE 20S ACROSS MUCH OF THE CWFA TUESDAY
AFTERNOON. IN FACT...BUFKIT SOUNDINGS IMPLY THAT MOS DEWPOINTS MAY
BE 3 TO 5 DEG TOO HIGH IN SOME INSTANCES. WHILE I DID GO A LITTLE
UNDER MOS...I DIDN/T GO THAT LOW. WITH DOWNSLOPE HELPING TO WARM MAX
TEMPS INTO THE M60S TO NEAR 70 IN THE FOOTHILLS AND PIEDMONT...MIN
RH/S WL FALL TO 25 PERCENT OR LESS IN MANY LOCATIONS. ATTM WINDS ARE
NOT STRONG ENOUGH TO WARRANT A RED FLAG WATCH. HOWEVER...BOTH THE
NAM...AND ESPECIALLY THE GFS...STILL HAVE QUITE STRONG CYCLONIC FLOW
OVER THE REGION. THEREFORE...THE MODEL WINDS MAY ALSO BE UNDERDONE
FOR TUE. CONSIDERING THE UNCERTAINTY IN THE WINDS AND IN HOW MUCH
WETTING RAIN WE WLL GET...DO NOT PLAN TO ISSUE A FIRE WEATHER WATCH
THIS PACKAGE. HOWEVER...IF QPF IS LIGHT...A WATCH WL LIKELY NEED TO
BE ISSUED LATER TONIGHT OR TOMORROW.
