AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
800 PM EDT SUN AUG 21 2011

.SYNOPSIS...
COLD FRONT CROSSES TONIGHT. HIGH PRESSURE BUILDS IN MONDAY AND LINGERS
ON TUESDAY. MOISTURE INCREASES AGAIN BY WEDNESDAY NIGHT. A COLD
FRONT STALLS OUT THURSDAY NIGHT...AS IRENE REACHES SE US.

&&

.NEAR TERM /THROUGH MONDAY/...
NOT MANY CHANGES MADE TO THE PREVIOUS FORECAST AS IT LOOKS TO BE
ON TRACK. COLD FRONT AS OF 2330Z APPEARS TO HAVE JUST ENTERED SE
OHIO ZONES...AND APPEARS TO BE PUSHING SOUTH INTO MORGAN AND
ATHENS COUNTIES. THIS FRONTAL BOUNDARY WILL BE SLOW TO MOVE ACROSS
THE CWA...AND IS NOT EXPECTED TO EXIT THE CWA UNTIL TOMORROW
MORNING...PROBABLY IN THE 10 TO 12Z TIME FRAME. MODELS HAVE HAD
DIFFICULTY IN THE TIMING OF THIS FRONT...SO IT IS POSSIBLE THE
TIMING MAY BE EVEN SLOWER THAN WHAT MODELS SUGGEST. AHEAD OF THE
FRONT...SHOWERS AND THUNDERSTORMS WILL CONTINUE FOR MUCH OF THE
EVENING. A FEW STORMS THIS EVENING HAVE BEEN SEVERE...MAINLY WITH
DOWNED TREES REPORTED.

WELL NORTH OF THE CWA...DRIER AIR IS BEGINNING TO FILTER IN BEHIND
THE FRONT...WITH DEW POINTS IN THE LOWER 50S OBSERVED IN NORTHERN
INDIANA...SOUTHERN MICHIGAN...AND NORTHWEST OHIO. THESE LOWER DEW
POINTS WILL GRADUALLY WORK THEIR WAY SOUTH INTO OUR CWA ON
MONDAY...PROVIDING FOR A MUCH MORE PLEASANT DAY. SOME OF THE
MODELS EVEN SUGGEST DEW POINTS DROPPING INTO THE 40S ACROSS PARTS
OF THE CWA...PARTICULARLY OVER NORTHERN WV AND THE HIGHER TERRAIN
TOMORROW NIGHT. THIS DRY AIR AND EXPECTED CLEAR SKY WILL ALLOW FOR
TEMPS MONDAY NIGHT TO COOL OFF NICELY.

KEPT PRETTY MUCH A SIMILAR IDEA IN TERMS OF FOG FORMATION FOR
TONIGHT AS COMPARED WITH PREVIOUS FORECAST...MAINLY OVER THE
NORTHERN HALF OF THE CWA WHERE BETTER CLEARING SHOULD BE ABLE TO
TAKE PLACE. CLOUD COVER WILL CONTINUE TO LINGER OVER HIGHER
TERRAIN TONIGHT...BEFORE FINALLY LIFTING OUT TOMORROW INTO A
SCATTERED CU DECK.

PREVIOUS DISCUSSION FOLLOWS...
FRONTAL BOUNDARY IS NOW APPROACHING CMH/CVG AND MOVING SLOWLY
SOUTHEAST.  EXPECT IT TO BE JUST EAST OF THE OHIO RIVER BY 00Z AND
CROSS THE MOUNTAINS BY 06Z.  STORMS HAVE FIRED OUT AHEAD AS ENOUGH
DESTABILIZATION HAS OCCURRED DUE TO HEATING...WITH 1000-1500 J/KG OF
MLCAPE.  WHILE OVERALL FLOW PATTERN IS MARGINAL...CWA COULD GET
SKIMMED BY AN AREA OF 40 KNOTS OF 0-6KM BULK SHEAR OVER THE NEXT FEW
HOURS ACROSS ROUGHLY THE NORTHERN HALF OF THE CWA.  SPC HAS THIS
AREA UNDER A SLIGHT RISK...AND A FEW MARGINAL HAIL/WIND EVENTS ARE
POSSIBLE DURING THE LATE AFTERNOON AND EARLY EVENING.  HAVE TRACKED
LIKELY POPS AHEAD OF THE FRONT THROUGH 03Z.  THE STORMS HAVE BEEN
EFFICIENT RAINFALL PRODUCERS AS WELL...BUT HAVE HAD SUFFICIENT
MOVEMENT...SO AS FAR AS FLOODING CONCERNS WILL JUST NEED TO WATCH
FOR TRAINING/MULTIPLE HITS IN AN AREA.

LINGERING MOISTURE MAY ALLOW SOME SHRA TO CONTINUE IN THE POST-FROPA
CYCLONIC FLOW...BUT EXPECT ANY SUCH ACTIVITY TO BE DONE BY 12Z AS
HIGH PRESSURE STARTS TO NOSE IN.  BRUNT OF VORTICITY IN
EASTWARD-MOVING H500 TROUGH REMAINS OFF TO THE NORTH.  CLEARING IN
THE WEST OVERNIGHT SHOULD ALLOW SOME FOG TO FORM...ESPECIALLY IN
AREAS THAT RECEIVE RAIN.  MOISTURE GETS TRAPPED UNDERNEATH THE
INVERSION IN THE MOUNTAINS...AND FORESEE MORE STRATUS THAN FOG
THERE.  ONCE MIXING GETS GOING LATER IN THE MORNING...FOG/STRATUS
SHOULD LIFT INTO SCT-BKN CU FOR THE AFTERNOON...WITH A FAIR AMOUNT
OF SUNSHINE.

RAN WITH A ROUGH GUIDANCE BLEND FOR TEMPERATURES TONIGHT.  LOWERED
MONDAY MAX TEMPS FROM PREVIOUS BUT REMAINED ON THE WARM SIDE OF THE
GUIDANCE ENVELOPE.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/...
ADDED SOME FOG ALONG THE WARMER RIVERS FOR LATE MONDAY NIGHT INTO
EARLY TUESDAY MORNING.  OTHERWISE PLEASANT LATE SUMMER WEATHER
FIGURED.  ACTUALLY LOWERED MINIMUM TEMPERATURES A BIT FOR DAWN
TUESDAY.  THAT SHOULD BE OUR COOLEST OF THE WEEK.

MOISTURE INCREASES ON WEDNESDAY INTO WEDNESDAY NIGHT...BUT DYNAMICS
REMAIN WEAK.  POPS ONLY IN THE 20 TO 30 PERCENT RANGE FOR NOW.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
STRESSING THE SAME THEME AS YESTERDAY...BESIDES THE OBVIOUS KEY TO
THE LATER PERIODS...THE TRACK...SPEED...AND STRENGTH OF IRENE...
ANOTHER MAJOR KEY IS WHERE THE FRONT STALLS AND WEAKENS THURSDAY
NIGHT INTO FRIDAY.  THIS IS THE FRONT THAT APPROACHES US WEDNESDAY
NIGHT INTO THURSDAY.  STILL HAVE THIS SURFACE FEATURE WEAKENING AND
STALLING OVER SOUTHERN WEST VIRGINIA OR SOUTHWEST VIRGINIA THURSDAY
NIGHT INTO FRIDAY...WITH THE FRONTAL ZONE ALOFT
EVEN FURTHER N.

LEFT THE CHANCE POPS FRIDAY NEAR THE OLD FRONT IN SOUTHERN
COUNTIES...WITH POPS AOB 14 PCT FOR SE OHIO FRIDAY INTO SATURDAY.
POPS INCREASE SATURDAY AND SATURDAY NIGHT FOR OUR EASTERN SLOPE
COUNTIES AS THE EXPECTED PATH OF IRENE THROWS MOISTURE WEST.

AS THIS DISTANCE...OUR DETERMINISTIC POPS PEAK SATURDAY NIGHT INTO
SUNDAY MORNING FOR THE REMAINS OF IRENE...BEFORE DECREASING FROM SW
TO NE SUNDAY NIGHT. EVEN HAVE LIKELY POPS FOR OUR MOUNTAINS AT THIS
DISTANCE. OF COURSE...THE EXACT STRENGTH OF IRENE AT LANDFALL...
SPEED AND TRACK WILL DETERMINE THE EVENTUAL PEAK TIME AND WESTERN
GRADIENT OF THE POPS.

AS YESTERDAY...STILL HAVE LOW CONFIDENCE IN MAXIMUM TEMPERATURES ON
FRIDAY.  FOR EXAMPLE...WEST OF THE MOUNTAINS...IN SOUTHERN WV COULD
PICTURE LINGERING CLOUDS AND A FEW SHOWERS WITH THE OLD FRONT...OR
THE OTHER SCENARIO...WOULD BE DOWNSLOPE E WINDS AND SUNSHINE WITH
WARMER TEMPERATURES.

KEPT MAXIMUM TEMPERATURES BELOW GUIDANCE FOR OUR MOUNTAINOUS
COUNTIES SATURDAY AND SUNDAY.

&&

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
00Z MONDAY THROUGH 00Z TUESDAY...
SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE TO PUSH NORTH TO
SOUTH ACROSS THE AREA AS A COLD FRONT PUSHES INTO THE REGION. AT
00Z MONDAY...COLD FRONT WAS JUST ENTERING SOUTHEAST OHIO. OUT
AHEAD OF THE FRONT...SHOWERS AND THUNDERSTORMS...WITH HEAVY
DOWNPOURS...PRODUCING BRIEF MVFR AND IFR VSBYS/CIGS...AND GUSTS OF
UP TO 40 KTS ARE OBSERVED. THESE SHOWERS AND THUNDERSTORMS WILL
CONTINUE TO PUSH SOUTH OVERNIGHT ALONG WITH THE COLD FRONT...WITH
SHOWERS/STORMS GRADUALLY EXITING TO THE SOUTH AFTER 06-09Z.

GRADUAL CLEARING IS EXPECTED TONIGHT...MAINLY OVER SOUTHEAST
OHIO...EASTERN KENTUCKY...AND CENTRAL AND NORTHERN WEST VIRGINIA.
IFR FOG IS EXPECTED TO DEVELOP IN AREAS WHERE CLEARING TAKES
PLACE...MAINLY AFTER 06-08Z TIME FRAME. OVER THE HIGHER
TERRAIN...MVFR CLOUDS MAY LINGER THROUGH AROUND 15Z.

AFTER 15Z...ALL LOCATIONS ARE EXPECTED TO RETURN TO VFR WITH LIGHT
NW WINDS FOR THE REMAINDER OF THE PERIOD.

ALTERNATE SCENARIOS: TIMING OF CONVECTIVE STORMS THIS
