AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE CHARLESTON WV
300 PM EDT FRI MAY 13 2005

.SHORT TERM (TONIGHT THROUGH MONDAY NIGHT)...

INSTABILITY WEST OF MOUNTAINS THIS EVE WILL MEAN TSTORMS UNTIL SUN
GOES DOWN.  HAVE PLAYED THE APPROACH OF PRECIPITATION TONIGHT LATE
AS ETA IS FASTEST OF MODEL AND IT HOLDS THINGS WEST OF OHIO RIVER.
RAISED MINS TONIGHT WITH GRADIENT INCREASING.

INCREASED TEMPS A COUPLE OF DEGREES ACROSS THE BOARD FOR
SATURDAY...WHICH WILL RESULT IN HIGHS RIGHT AROUND 80 DEGREES FOR
ALL BUT HIGHEST LOCATIONS IN CWA.

NAM INITIALLY QUICKER WITH THE FRONTAL PASSAGE...THEN SLOWS DOWN THE
HIGH PRESSURE MOVING IN SUNDAY EVENING...BUT OVERALL PRETTY
CONSISTENT WITH GFS SOLUTION.  WITH PLENTY OF CLOUDS AROUND WILL
KICK UP SATURDAY NIGHT/SUNDAY MORNING TEMPS AS WELL.  GUIDANCE
VALUES HERE ARE VERY WITHIN A COUPLE OF DEGREES OF EACH OTHER HERE.
WITH HIGH PRESSURE NOT IN A HURRY TO BUILD IN...LINGERING MOISTURE
AND SOME INSTABILITY MAY LEAD TO A FEW SHOWERS SUNDAY AFTERNOON
ACROSS THE HIGHER ELEVATIONS OF THE EASTERN CWA.

A PRETTY GOOD COOL DOWN IS FIGURED FOR SUNDAY NIGHT INTO MONDAY
MORNING...AS 850MB TEMPS FALL TO -1C BY 12Z MONDAY.

OTHERWISE...HIGH PRESSURE OVERHEAD MONDAY NIGHT INTO TUESDAY.

&&

.PREVIOUS DISCUSSION...
(ISSUED 140 PM EDT FRI MAY 13 2005)

AVIATION...

MOSTLY CLEAR SKY LATE THIS MORNING INTO THE EARLY AFTERNOON
HOURS...ARE BEGINNING TO Q UP.  WILL WATCH THE POP UP SHOWERS ACROSS
E KY AND W VA...AS THEY NEAR BKW.  HAVE INCLUDED THE POSSIBILITY OF
A THUNDERSTORM HERE FOR MID AFTERNOON.  OTHERWISE...VFR CONDITIONS
ALL AROUND.  HIGH PRESSURE TO OUR SOUTHEAST IS WORKING HARD TO KEEP
THE AFTERNOON CUMULUS FROM FORMING...BUT IN A LOSING BATTLE.  OVER
THE NEXT 18 HOURS...VFR CONDITIONS ARE EXPECTED TO DOMINATE.
HOWEVER...TOWARDS THE END OF THE PERIOD COLD FRONT WILL ENTER THE
PICTURE FROM THE WEST.  WILL NEED TO LOWER CEILINGS AND START THE
MENTION OF SHOWERS AND EVEN THE POSSIBILITY OF A THUNDERSTORM AFTER
DAY BREAK SATURDAY.  BY 18Z...THE COLD FRONT WILL BE ACROSS WESTERN
OHIO.  WINDS WILL ALSO BE ON THE INCREASE SATURDAY WITH WINDS AROUND
10 TO 15 KTS COMMON...WITH HIGHER GUSTS.

PREVIOUS DISCUSSION...
(ISSUED 1246 PM EDT FRI MAY 13 2005)

LONG TERM (TUESDAY THROUGH THURSDAY)...

HPC UTILIZED A MIDDLE OF THE ROAD APPROACH BETWEEN THE AMPLIFIED
CANADIAN AND THE SUPPRESSING GFS.  THIS HAPPENS TO BE VERY SIMILAR
TO THE ECMWF SOLUTION...BUT DID KICK THE COLD FRONT FOR THE MIDDLE
OF NEXT WEEK TO OUR EAST QUICKER...SIMILAR TO THE GFS FOR DAYS 6 AND
7.

PREVIOUS DISCUSSION...
(ISSUED 650 AM EDT FRI MAY 13 2005)

AVIATION...

LIFR CONDITIONS START THE PERIOD AT CRW/HTS BUT SHOULD BURN OFF
QUICKLY BY 15-16Z...OTHERWISE MVFR VISIBILITY AT BKW AND VFR
CONDITIONS ELSEWHERE.  VFR CONDITIONS SHOULD PERSIST FROM 18Z
THROUGH THE END OF THE TAF PERIOD.  WINDS WILL TURN SOUTHERLY AS
WARM FRONT LIFTS NORTH AND SOME LIGHT SHOWERS MAY APPROACH THE
WESTERN SITES CLOSE TO 12Z SATURDAY...BUT NOT ENOUGH CONFIDENCE TO
PUT IN TAFS.

PREVIOUS DISCUSSION...
(ISSUED 410 AM EDT FRI MAY 13 2005)

SHORT TERM (TODAY)...

THE FRONTAL BOUNDARY THAT PUSHED SOUTH THROUGH THE REGION EARLY
THURSDAY MORNING...WILL LIFT BACK NORTH TODAY AS SOUTHERLY WINDS
PICK UP AHEAD OF A STRONG SYSTEM LIFTED EAST OUT OF THE PLAINS.
SOME NOCTURNAL STRATUS HAS DEVELOPED ACROSS THE EASTERN CWA AND MORE
DEVELOPING ALONG THE OHIO RIVER...HOWEVER...EXPECT THIS WILL BREAK
UP DURING THE MORNING HOURS AS HEATING TAKES PLACE.

AS THE FRONTAL BOUNDARY LIFTS NORTH TODAY...850H TEMPS INCREASE TO
NEAR +16C.  THINK THERE WILL BE ALOT OF SUNSHINE SEEN THROUGH A
DEVELOPING CUMULUS FIELD EARLY THIS AFTERNOON.  INSTABILITY WILL BE
MODERATE BY LATE AFTERNOON...ALTHOUGH SOUNDINGS INDICATE A LITTLE
BIT OF A CAP...BUT THERE IS NOT VERY MUCH MOISTURE AVAILABLE OUTSIDE
OF THE BOUNDARY LAYER MOISTURE...AND THERE IS NO REAL FORCING
MECHANISM TO INITIATE CONVECTION.  THEREFORE HAVE CARRIED ONLY
SLIGHT CHANCE POPS TODAY...THINKING HEATING ALONE COULD BE ABLE TO
POP A FEW THUNDERSTORMS.  WENT ABOVE MOS FOR TEMPS TODAY...THINKING
SUNSHINE COMBINED WITH WARMING 850H TEMPS WOULD ALLOW TEMPERATURES
TO REACH MID 80S ACROSS THE LOWLANDS.  THIS IS SUPPORTED BY FORECAST
SOUNDINGS.

(TONIGHT THROUGH SUNDAY NIGHT)...

MODELS IN GOOD AGREEMENT WITH A FAIRLY STRONG COLD FRONT COMING
ACROSS THE REGION EARLY SATURDAY NIGHT. GOOD MOISTURE SURGE ON
MODERATE SOUTHWESTERLY LOW LEVEL JET...ALONG WITH GOOD INSTABILITY
AND DYNAMICS...WILL BRING SHOWERS AND THUNDERSTORMS AHEAD OF THE
FRONT. TIMING OF THE FRONT WILL FOCUS THE BEST CHANCE OF PRECIP
SATURDAY INTO SATURDAY EVENING. HOWEVER...MODELS DO SHOW A DECENT
SOUTHWESTERLY LOW LEVEL JET SETTING UP OVER THE WESTERN HALF OF THE
REGION TONIGHT...WHICH WOULD AID ANY NOCTURNAL DEVELOPMENT...SO THAT
DECENT CHANCE POPS ARE IN THE FORECAST OVER NORTHWESTERN SECTIONS
TONIGHT WITH LESSER CHANCE FARTHER EASTWARD. MIDDLE OF THE ROAD MAV
TEMPERATURE GUIDANCE SEEMS REASONABLE ON SATURDAY.

BEHIND THE FRONT...HIGH PRESSURE STRUGGLES TO BUILD IN QUICKLY...SO
THAT LINGERING MOISTURE AND SOME INSTABILITY SUNDAY MAY LEAD TO A
FEW SHOWERS...ESPECIALLY IN THE MOUNTAINS. MUCH COOLER TEMPERATURES
SUNDAY...ESPECIALLY ALOFT WHICH WOULD BE THE MAIN CAUSE FOR THE
ENHANCED INSTABILITY. MODELS CLOSE FOR SUNDAY TEMPS. CLEARING SUNDAY
NIGHT AND MUCH COOLER AS HIGH PRESSURE FINALLY TAKES CONTROL.
