CORRECTED NAME OF TROPICAL STORM IN SECOND PARAGRAPH

.SHORT TERM (TONIGHT THROUGH FRIDAY)...
ATMOSPHERE UNSTABLE WITH CAPES BTWN 2000-3000 J/KG BY MID AFTN.
BEST LOW LEVEL CONVERGENCE LIES WITH A COLD FRONT OVER W TN AND
WITH A VERY WEAK LEE TROF E OF THE BLUE RIDGE. GFS SHOWS WEAK
CONFLUENT FLOW ALOFT WITH WEAK WARM ADVECTION WHICH WILL TEND TO
MINIMIZE CONVECTION. THE NAM HOWEVER...SHOWS WEAK H5 PVA
APPROACHING THIS EVE WITH BEST LOW LEVEL CONVERGENCE OVER CNTRL
CAROLINAS. SINCE SCT CONVECTION ALREADY GOING WILL LEAN SLIGHTLY
TOWARD NAM THIS EVE. WINDS ALOFT ARE STRONGER SO STORMS SHOULD MOVE E
FASTER THAN ON PREVIOUS DAYS. STRAIGHT-LINE WIND GUSTS APPEAR TO BE
THE MAIN THREAT THIS EVE. THERE IS THE THREAT OF FLASH FLOODING WITH
HEAVY RAIN AS WELL...MAINLY WHERE ANY TRAINING OR BACK BUILDING
CELLS OCCUR.

BIG STORY IS TS CINDY WHICH IS FORECAST TO MAKE LANDFALL NEAR NEW
ORLEANS LATE TONIGHT. MODELS ARE ALL OVER THE PLACE SO HAVE USED THE
LATEST NHC AND HPC GUIDANCE TO BRING THE LOW N...TO FORM A WAVE ON A
FRONTAL BOUNDARY OVER N CNTRL AL THU MORNING. THIS THEN TRACKS TO
THE NE...WEST OF THE MOUNTAINS..KEEPING CWA IN MOIST UPSLOPE FLOW
LATE WED INTO FRI.

&&

.LONG TERM (FRIDAY NIGHT THROUGH TUESDAY)...
EXTENDED FORECAST REMAINS UNCERTAIN WITH TWO TROPICAL SYSTEMS IN THE
MIX. NAM AND GFS ARE OF LITTLE HELP AND HPC HAS CHOSEN TO STICK
PRETTY CLOSE TO THE 00Z ECMWF MODEL. LATEST NHC TRACK AND HPC
GUIDANCE HAS AREA OF LOW PRESSURE RELATED TO REMNANTS OF TS CINDY
VCNTY E KY...W VIRGINIAS BY EARLY SAT MORNING...SO MOISTURE SHOULD
BE PULLING OFF TO THE NE OF THE CWA DURG THE DAY SAT. HIGH
PRESSURE IS EXPECTED TO BUILD IN FROM THE NW SUN WHICH SHOULD KEEP
THINGS FAIRLY DRY THROUGH MON. THEN...TROPICAL STORM DENNIS IS
FORECAST TO MAKE LANDFALL ALONG GULF COAST BTWN PENSACOLA AND
BILOXI SOMETIME LATER MON OR EARLY TUE AND TRACK TO THE NW
INTIALLY...THEN SLOWLY TURN N. THIS COULD BRING ABUNDANT TROPICAL
MOISTURE OVER THE AREA AGAIN FOR THE FIRST PART OF NEXT WEEK.

&&

.AVIATION...
CONVECTION WILL INCREASE IN COVERAGE ACROSS THE AVIATION FORECAST
AREA THROUGH THE LATE AFTERNOON HOURS. STRONGEST FORCING FROM UPPER
LEVEL SHORTWAVE WILL AFFECT THE NORTHERN TIER...BRINGING THE HIGHEST
THUNDER CHANCES FROM KAVL TO KHKY THROUGH 01Z. GIVEN MID LEVEL DRY
AIR IN SOUNDINGS...WILL ALSO FEATURE A 30 KT GUST POTENTIAL AT THOSE
TAF LOCATIONS. FLOW WILL BECOME MORE W TO NW BEHIND THE WAVE AND
PRECIP CHANCES WILL DIMINISH OVERNIGHT. ABUNDANT LOW LEVEL MOISTURE
WILL ALLOW MVFR FOG TO DEVELOP...WITH IFR CIG AND VSBY ONCE AGAIN
POSSIBLE AT KAVL CIRCA 12Z WED. HIGH CLOUD SHIELD AHEAD OF TROPICAL
STORM CINDY WILL LIKELY BEGIN TO SPREAD OVER THE AREA DURING THE
OUTLOOK PERIOD.
