AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
800 PM EDT TUE OCT 6 2009

.SYNOPSIS...
A COLD FRONT SWEEPS THROUGH TONIGHT WITH GUSTY WINDS INTO WEDNESDAY.
HIGH PRESSURE WEDNESDAY NIGHT INTO THURSDAY. WARMER THURSDAY INTO
FRIDAY. THE NEXT COLD FRONT PASSES FRIDAY NIGHT.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
FORECAST UPDATED THIS EVENING TO KEEP UP WITH LATEST TRENDS IN RADAR
AND FRONTAL POSITION. ALSO...REMOVED SHOWER CHANCES IN THE MOUNTAINS
ON WEDNESDAY...BECAUSE OF HOW DRY OVERALL ATMOSPHERIC COLUMN WILL
BECOME.

WITH RECENT EXIT OF PREFRONTAL WAVE FROM THE FAR SOUTHERN
ZONES...MAIN RAIN PRODUCER NOW WILL BE THE COLD FRONT ITSELF. THE
FRONT WILL MOVE FAIRLY QUICKLY NORTHWEST TO SOUTHEAST THROUGH THE
AREA 03Z-08Z. WHILE MOST OF THE AREA WILL SEE A PERIOD OF RAIN WITH
THE FRONT...THIS WILL BE ESPECIALLY THE CASE IN THE SOUTHEAST HALF
OF THE AREA WHERE MOISTURE WILL HAVE THE MOST TIME TO POOL ALONG THE
FRONT AND OROGRAPHIC LIFT WILL ENHANCE SHOWERS. ABOUT 0.3 TO 0.4 OF
AN INCH OF RAIN CAN BE EXPECTED IN THE MOUNTAINS...BUT LESSER
AMOUNTS IN THE LOWLANDS...ESPECIALLY IN SOUTHEAST OHIO WHERE AROUND
A TENTH OF AN INCH OR LESS WILL FALL.

PRIMARY WEATHER MAKER ASIDE FROM THE SHOWERS WILL BE THE WIND. WIND
BECOMES ALIGNED THROUGH THE COLUMN FAIRLY WELL AFTER 03Z WEST...06Z
ALONG THE CENTRAL LOWLANDS...AND 08Z FOR THE MOUNTAINOUS COUNTIES TO
THE EAST. SHOULD BE ABLE TO TRANSFER MOMENTUM TO THE SURFACE FAIRLY
EFFICIENTLY...BUT 850HPA WINDS AT AROUND 45KTS PEAK SHOULD ONLY
TRANSLATE TO 25-30KTS DOWN AT THE SURFACE. RIDGE TOPS WILL SEE THE
BEST GUSTS UPON FRONTAL PASSAGE...AND MAY REACH THE 40KT THRESHOLD.
HOWEVER...THIS SHOULD BE ISOLATED...AND WILL NOT REACH THE COUNTY
AVERAGE CRITERIA FOR ADVISORIES.

BEHIND THE FRONT WEDNESDAY...LOOKING AT HIGH TEMPERATURES ABOUT 8-12
DEGREES COOLER COMPARED TO HIGHS TUESDAY. ALSO...GOOD MIXING WILL
ALLOW FOR GUSTS GENERALLY OF 20-30 MPH IN THE LOWLANDS...AND 30-40
MPH AT THE HIGHEST ELEVATIONS.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
MODELS BRING A WARM FRONT NORTHWARD THURSDAY NIGHT...FOLLOWED BY AN
APPROACHING STRONG COLD FRONT FRIDAY...AS SURFACE LOW PRESSURE LIFTS
NORTHEASTWARD THRU THE CENTRAL OHIO VALLEY AND INTO THE EASTERN
GREAT LAKES BY FRIDAY EVENING. UNTIL THEN...HIGH PRESSURE WILL BE IN
CONTROL WEDNESDAY NIGHT AND THURSDAY. UNDER IDEAL RADIATIONAL
COOLING CONDITIONS OF CLEAR SKIES AND CALM WINDS...WE EXPECT MINS
WEDNESDAY NIGHT ON THE COOLER SIDE OF GUIDANCE. POSSIBLY SOME FROST
IN THE NORTHERN MOUNTAINS. AS HIGH PRESSURE MOVES OFF TO THE EAST
THURSDAY...THERE WILL BE INCREASING HIGH CLOUDS AND SOUTHERLY
WINDS...BUT NOT ENOUGH CLOUDS TO INHIBIT TEMPS FROM RISING WELL INTO
THE 70S.

FOR THE SYSTEM APPROACHING THURSDAY NIGHT AND FRIDAY...MODELS AGREE
MUCH OF THE DYNAMICS AND MOISTURE WITH THE WARM FRONT THURSDAY NIGHT
WILL BE WEST AND NORTH OF OUR CWA. EXPECT SERN OHIO AND NORTHWESTERN
WEST VIRGINA WILL BE CLIPPED BY THE SHOWER ACTIVITY WITH THE WARM
FRONT.

THE COLD FRONT TIMING FOR FRIDAY IS HANDLED DIFFERENTLY BY THE
MODELS...RANGING FROM THE SLOWEST NAM TO THE FASTEST GFS. PER
HPC...A COMPROMISE IS IN ORDER WHICH FOLLOWS THE GEM MODEL CLOSELY.
THIS PLACES THE COLD FRONT JUST WEST OF THE OHIO RIVER BY FRIDAY
EVENING. GOOD DYNAMICS...MOISTURE INFLOW...AND AT LEAST MARGINAL
INSTABILITY BRINGS HIGH CHANCES FOR SHOWERS AND EVEN A FEW
THUNDERSTORMS FRIDAY. STILL...TEMPERATURES WILL BE ABOVE NORMAL WITH
A BRISK SOUTHERLY FLOW...ESPECIALLY IN THE EAST WHERE SHOWERS COME
IN THE AFTERNOON. GOING ON THE HIGH SIDE OF TEMPERATURE
GUIDANCE.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
ROLLED WITH HPC SOLN WHICH BRINGS A COLD FRONT  THROUGH THE AREA FRI
NT FOLLOWED BY A DRY...COOLER INTERLUDE COINCIDENT WITH NEXT WEEKEND
PER ZONAL FLOW ALOFT AND HIGH PRESSURE AT THE SURFACE.  UPPER FLOW
BACKS LATE IN THE WEEKEND IN RESPONSE TO NEXT SHORT WAVE TROUGH IN
THE FAST FLOW THAT MOVES THROUGH EARLY NEXT WEEK.

USED MOSTLY A BLEND OF HPC AND PREV FOR TEMPERATURES...WHICH WERE
LOWER THAN THE MEX IN MOST CASES AS HPC ROLLED WITH COOLER MODEL
SOLNS.

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
COLD FRONT SWEEPS NORTHWEST TO SOUTHEAST DURING 03Z-08Z TIME. CIGS
DROP TO MVFR LEVELS ALONG AND BEHIND FRONT...BEFORE LIFTING AND
MIXING OUT 09Z-14Z PERIOD /SLOWEST IN THE MOUNTAINS/. HOWEVER...WITH
SHOWERS IN THE NEAR VICINITY OF THE FRONT...IFR CONDITIONS WILL
PROBABLY BRIEFLY OCCUR WITH THE HEAVIER SHOWERS.

WIND WILL VEER FROM SOUTH TO SOUTHWEST AS FRONT PASSES...THEN TO
WESTERLY BEHIND THE FRONT DURING THE DAY WEDNESDAY. GUSTS TO 25KTS
ARE POSSIBLE THROUGHOUT THE LOWLANDS...AND CLOSER TO 35-40KTS ACROSS
THE RIDGE TOPS.

AFTER 00Z THURSDAY...
IFR VALLEY FOG EXPECTED DURING PREDAWN HOURS THURSDAY IN THE
ELEVATED MOUNTAIN VALLEYS SUCH AS TYGART AND GREENBRIER...INCLUDING
KEKN. IFR SHOWERS POSSIBLE WITH A COLD FRONT FRIDAY AND FRIDAY NIGHT.
