AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
646 AM EDT TUE MAY 8 2012

.SYNOPSIS...
COLD FRONT CREEPS EAST TODAY...THROUGH THE MOUNTAINOUS COUNTIES THIS
EVENING. HEAVY RAIN THREAT DIMINISHES WEST TO EAST AS THE DAY WEARS
ON. DRIER AND COOLER AIR WEDNESDAY NIGHT. HIGH PRESSURE THURSDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
AT 08Z...LOW PRESSURE WAVE FROM WRN LAKE ERIE THROUGH FDY.  COLD
FRONT APPROACHING BUT STILL WEST OF DAY...CVG AT THAT HOUR.

MAIN FOCUS THROUGH DAWN SHOULD BE THE OHIO RIVER COUNTIES INTO NORTH
CENTRAL WEST VIRGINIA.  THESE RAIN RATES ARE NOT YOUR SUMMER
DRENCHING DOWNPOUR...BUT STILL HEALTHY...ABOUT .5 TO 1 INCH HAVE
BEEN OBSERVED IN THE HEAVIEST BANDS...AND THESE RATES ARE STILL
LIKELY THIS MORNING.  DUE TO THE WET GROUND...DECIDED TO EXPAND THE
WATCH...WITH THE WESTERN SEGMENT THROUGH 15Z AND THE EASTERN ONE
THROUGH 18Z.  I MAY HAVE BEEN TOO LIBERAL ON THE EASTERN EDGE TO EKN
AND CRW.

STREET FLOODING AND POOR DRAINAGE FLOODING LIKELY...BUT HOPING WE
CAN ESCAPE THE REAL SERIOUS FLOODING.

THE LAST SIGNIFICANT 500 MB VORT MAX SHOULD BE PASSING HTS AROUND
12Z LIFTING NE AND PASSING CKB AROUND 15Z.  A TRAILING WEAKEN VORT
MAX STILL WILL BE PASSING THIS AFTERNOON.

WE CONTINUED TO BE RATHER PESSIMISTIC IN THE CLEARING FROM WEST TO
EAST.  THE PROBLEM...AFTER THE DEPTH MOISTURE PULLS OUT...THE LOW
LEVELS MAY REMAIN NEARLY SATURATED LATE THIS AFTERNOON IN WEST
VIRGINIA...LEADING TO LOTS OF LOW CLOUDS.  DESPITE THE CLOUDS...FOG
COULD STILL FORM. DO HAVE SOME PARTIAL CLEARING REACHING INTO
SOUTHEAST OHIO THIS AFTERNOON AND EVENING.

DID A VERY SLIGHT DIURNAL TEMPERATURE RISE IN WV DUE TO THE
RAIN.

DID NOT HAVE THE TIME TO SPEND MUCH ON LOW TEMPERATURES TONIGHT...
BUT WITH THE MOISTURE LINGERING IN THE HILLS AND HOLLOWS OF WEST
VIRGINIA...TRIED TO STAY ON THE HIGHER SIDE...WITH THE GRADIENT
MAINLY IN SE OHIO AND NEAR GREENUP AND CARTER COUNTIES KY.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
00Z NAM SHOWS SURFACE COLD FRONT JUST SOUTHEAST OF CWA TO START THE
PERIOD...HOWEVER AN UPPER LEVEL RIPPLE WILL BE SLIDING NE OUT OF
TENNESSEE CLOSE TO THE SURFACE FRONT...WHILE AN UPPER LEVEL TROUGH
SLIDES SOUTHEAST FROM THE WESTERN GREAT LAKES. THE 00Z GFS IS A BIT
FASTER WITH THE UPPER LEVEL TROUGH COMING OUT OF THE GREAT
LAKES...BUT NOT BY MUCH. REGARDLESS...THESE TWO FEATURES WILL BE
ENOUGH TO KEEP SLIGHT CHANCE POPS ACROSS MUCH OF THE LOWLANDS
WEDNESDAY..WITH CHANCE POPS IN WV MOUNTAINS. DID KEEP THE TRI-STATE
AREA DRY...AS THEY SHOULD BE TOO FAR WEST TO BE INFLUENCED BY THE
WAVE SLIDING UP THE FRONT...AND TOO FAR SOUTH TO GET MUCH IMPACT
FROM THE NORTHERN TROUGH. THE SHOWERS WILL DWINDLE DOWN TO JUST A
SLIGHT CHANCE IN THE MOUNTAINS BY LATE EVENING. HIGH PRESSURE STARTS
TO BUILD IN WEDNESDAY NIGHT AND WILL KEEP THINGS DRY AND A BIT
COOLER THROUGH THE REST OF THE SHORT TERM. THURSDAY SHOULD BE THE
COOLEST DAY...WITH HIGHS IN THE 60S FOR THE LOWLANDS AND 50S IN THE
MOUNTAINS. THURSDAY NIGHT WE COULD SEE SOME FROST...OR EVEN FREEZE
CONDITIONS ACROSS THE NORTHERN MOUNTAINS.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
SFC HIGH IN CONTROL THROUGH SATURDAY. GRADUAL WARMUP EXPECTED
INTO THE WEEKEND...AS FLOW SHIFTS TO THE SW.

COLD FRONT PASSES THROUGH ON SUNDAY...BRINGING THE CHANCE FOR MORE
SHOWERS OR THUNDERSTORMS TO THE CWA. TEMPERATURES ARE EXPECTED TO
BE ON THE WARM SIDE SUNDAY.

&&

.AVIATION /12Z TUESDAY THROUGH SATURDAY/...
AIR BECOMES SATURATED THROUGHOUT THE LOW LEVELS AHEAD OF THE COLD
FRONT...FIRST IN THE LOWLANDS PRIOR TO DAWN...THEN MOVING EAST.
THE LOWER LEVELS REMAIN REMAIN SATURATED FROM CKB-CRW ON EAST INTO
THE MOUNTAINS THROUGH TONIGHT...WITH EVEN SOME MID LEVEL MOISTURE
RETURNING WITH WEAK WAVE ALONG THE FRONT. SO FIGURING CEILING
HEIGHTS STAYS DIFFICULT. ALSO DIFFICULT TO FIGURE IS THE COVERAGE OF
THUNDERSTORMS IN THE MOUNTAINS THIS AFTERNOON...AFTER THE 500 MB
VORT SUPPORT EXITS THIS MORNING...BUT STILL ALONG THE COLD FRONT.

THE MAXIMUM COVERAGE AND INTENSITY OF SHOWERS WAS 09Z TO ABOUT 12Z
THIS MORNING WITH SUPPORT INTO THE MID OHIO VALLEY COUNTIES.
THAT SUPPORT LIFTS NORTHEAST 12Z TO 15Z WITH SOME WEAKENING.
SO COVERAGE OF SHOWERS SHOULD BE DECREASING VCNTY OF THE OHIO RIVER
COUNTIES AFTER 12Z...BUT WITH FRONT STILL TO THE WEST...OCCASIONAL
SHOWERS STILL LIKELY.

COVERAGE OF SHOWERS SHOULD INCREASE OVER THE MOUNTAINOUS COUNTIES
12Z TO 15Z. CEILINGS LOWERING AND BECOMING 2 TO 4 THSD FT BKN TO OVC
AND WIDESPREAD VSBY 3 TO 5 MILES IN PCPN. LOCAL DOWNPOURS WILL LOWER
VSBY NEAR 1 MILE WITH CEILINGS 1 TO 2 THSD FT BKN.  SOME STRATUS
CEILINGS AOB 1 THSD FT BKN POSSIBLE IN THE VCNTY OF THE COLD
FRONT.

FRONT REACHES MOUNTAINOUS COUNTIES BY 00Z WEDNESDAY...WITH
IMPROVING CONDITIONS IN SOUTHEAST OHIO...SCATTERED TO BROKEN
CLOUDS 2 TO 3 THSD FT. HOWEVER...FIGURING ON LOTS OF LINGERING
LOW LEVEL MOISTURE CKB-CRW ON EAST...WITH LINGERING LIGHT SHOWERS
AND THE POSSIBILITY OF STRATUS FORMING AOB 1 THSD FT BKN AND VSBY
BECOMING AOB 3 MILES 03Z TO 06Z WEDNESDAY.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 12Z WEDNESDAY...

FORECAST CONFIDENCE...LOW.

ALTERNATE SCENARIOS: CEILINGS MAY NOT DROP AS LOW TUESDAY NIGHT IN
THE LINGERING LOW LEVEL MOISTURE IN THE WAKE OF THE SLOW MOVING
COLD FRONT...IN THE MOUNTAINS AND WESTERN SLOPES.
