AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
756 PM EDT SAT JUN 4 2011

.SYNOPSIS...
COLD FRONT APPROACHES TONIGHT...SLIPPING THROUGH THE AREA SUNDAY
INTO SUNDAY NIGHT. HIGH PRESSURE SAILS ACROSS MONDAY. A WARM FRONT
CROSSES TUESDAY. ANOTHER COLD FRONT ARRIVES LATE WEEK.

&&

.NEAR TERM /THROUGH SUNDAY NIGHT/...
WEAK WARM FRONT WILL RACE THROUGH THE CWA THIS AFTERNOON AND
EXIT. A THIN LINE OF CONVECTION HAS FORMED AND HAS BEEN SPOTTY
ALONG THE FRONT. CONVECTION HOLDING TOGETHER DESPITE HEADING INTO
LOWER DEW POINTS AND DRIER AIR. THESE STORMS HOWEVER SHOULD WEAKEN
AND FALL APART AS IT DOES. LOW PRESSURE OVER GREAT LAKES WILL DROP
SOUTH OVERNIGHT AND TRAILING COLD FRONT WILL MOVE ACROSS THE CWA
LATER TONIGHT AND SUNDAY. KEPT LIKELY POPS INITIALLY NW AND THEN
GENERALLY WENT WITH HIGH CHC POPS THE REST OF THE WAY AS FRONT
MOVING THROUGH AT NIGHT/EARLY MORNING. FRONT PUSHES JUST SOUTH OF
THE REGION BY LATE SUNDAY. AS IT PUSHES SOUTHEAST...SHOWER AND
STORM CHANCES SHOULD DECREASE FROM THE NORTHWEST. HIGH PRESSURE
BUILDS IN LATE SUNDAY NIGHT. LATEST MAX/MIN GUID REASONABLE WITH
ONLY A FEW ADJUSTMENTS.

&&

.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
HIGH PRESSURE TO START UNDER NW FLOW ALOFT.  AS HIGH EXITS TO THE SE
LATER MON...ALLOWING SW FLOW TO DEVELOP...RING OF FIRE PATTERN SETS
UP WITH CONVECTIVE COMPLEXES ALONG THE SOUTHERN EDGE OF THE
WESTERLIES RIDING OVER TOP OF THE RIDGE TO THE W AND THAN DOWN THE E
SIDE OF IT...MUCH LIKE WHAT HAPPENED OVER NY AND PA LATE LAST NIGHT
INTO TODAY.  NAM12 HINTS AS FIRST SUCH COMPLEX MON NT INTO TUE
MORNING...FOLLOWED BY ANOTHER LATE WED INTO WED NT.  OTHER MODELS
ARE MUCH MORE SUBTLE AT BEST WITH ANY SUCH FEATURES.

NW-SE ORIENTED WARM FRONT MOVES THROUGH THE AREA SOMETIME TUE.
THEREFORE...CONVECTIVE COMPLEXES HAVE A BETTER SHOT OF AFFECTING THE
AREA MON NT...E OF THE WARM FRONT...COMPARED WITH TUE NT...ONCE THE
FRONT HAS PASSED.  IF THE DEW POINT GRADIENT CANNOT CLEAR THE AREA
BY TUE NT...THEN THE DOOR IS LEFT OPEN A BIT.
GIVEN THE TOUGH NATURE OF HITTING THE FORMATION AND THEN
SUBSEQUENT TIMING AND OVERALL PLACEMENT OF COMPLEXES OF THIS
NATURE...AND PER ISC...KEPT POPS NO HIGHER THAN SLIGHT CHANCE MON
NT AND DID NOT EVEN CODE UP ANY ADDITIONAL COMPLEXES AT ALL AFTER
THAT AT THIS TIME.

LOWS LOOKED GOOD AT THIS DISTANCE.  UNLESS IT RAINS SOON...THINGS
ARE DRYING OUT...SO RAISED HIGHS TO THE LOWER MET...WITH THE
HIGHER MAV CONTINUING TO RUN TOO HIGH.  AGAIN...IF IT REMAINS
DRY...AND CLEANER RIDGING TAKES HOLD AT SOME POINT...THEN THE MAV
MAY BE GIVEN SOME CREDENCE.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
BASICALLY DRY FCST INTO THU AS UPPER RIDGING NOSES EWD INTO THE
AREA.  RIDGE IS ONCE AGAIN FLATTENED THU AS ANOTHER S/W TROF RIDES
OVER TOP OF IT.  THIS WILL PUSH A COLD FRONT THROUGH LATE THU NT OR
FRI.  HAVE SLIGHT CHANCE FOR DIURNAL CONVECTION WED WITH RIDGE
ALREADY FLATTENING AND SOUTHERN EDGE OF THE WESTERLIES A LITTLE
CLOSER TO THE AREA.  BETTER CHANCE THU INTO FRI AS THE COLD FRONT
NEARS AND THEN CROSSES.  BEST UPPER FORCING IS THU WITH WHAT IS
LEFT OF WEAK FRONT PUSHING S THROUGH THE AREA FRI AS UPPER ENERGY
MOVES E INTO NEW ENGLAND.

SHAKY HIGH PRESSURE BRINGS DRY WEATHER FOR THE BALANCE OF THE
PERIOD.  HIGH IS SHAKY IN THAT IT PASSES WELL N OF THE AREA.  THIS
MAY ALLOW THE COLD FRONT TO TURN AROUND AND RETURN AS A WARM FRONT
NEXT WEEKEND.

MINOR TEMPERATURE CHANGES WITH HPC AND MEX REASONABLY CLOSE IN MOST
CASES.  RATHER WARM TO HOT WED AND THU AND THEN A BIT COOLER TO
CLOSE OUT THE WEEK.

&&

.AVIATION /00Z SUNDAY THROUGH THURSDAY/...
STARTING THE PERIOD WITH VFR CONDITIONS. HOWEVER...SEVERE
THUNDERSTORMS WILL MOVE ACROSS SOUTHEAST OH...PASSING JUST WEST
OF PKB AROUND 01-02Z. THESE STORMS WILL MOVE SOUTH SOUTHEAST
ACROSS SOUTHEAST OH...PERHAPS IN BETWEEN OR AFFECTING HTS AND/OR
CRW. THE THREAT FOR BRIEF IFR CONDITIONS UNDER HEAVY THUNDERSTORMS
AND STRONG GUSTY WINDS EXISTS...BUT ITS DIFFICULT TO PINPOINT
STORM TRACKS AS THEY MOVE TO THE RIGHT OF THE MEAN FLOW.

BRIEF LOCALIZED MVFR CONDITIONS CAN BE EXPECTED IN THE VICINITY OF
THESE STORMS. CIGS 40-50CB WITH THIS LINE AS WELL. VFR ELSEWHERE
THROUGHOUT THE REST OF THE EVENING.

ADDITIONAL SHOWERS/STORMS OVERNIGHT MAY RESULT IN MVFR/IFR CONDITIONS
AFTER 06Z TONIGHT...MAINLY ACROSS THE NORTHERN SITES.
