AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
905 PM EDT MON MAY 23 2011

.SYNOPSIS...
A SERIES OF WEAK DISTURBANCES IN THE UPPER ATMOSPHERE AND A FRONTAL
BOUNDARY IN OUR VICINITY WILL COMBINE TO BRING PERIODS OF SHOWERS
AND THUNDERSTORMS THROUGH THE WEEK.

&&

.NEAR TERM /THROUGH TUESDAY/...
UPDATED AT 845 PM TO INCLUDE SEVERE THUNDERSTORMS WATCH EFFECTS IN
THE FORECAST UNTIL 2 AM TUESDAY MORNING.

EVENING UPDATE...MORE AGGRESSIVE WITH A SQUALL LINE PUSHING THRU AT
LEAST THE WESTERN HALF OF THE AREA LATER THIS EVENING BEFORE
WEAKENING SIGNIFICANTLY. UPPED POPS TO CAT WITH THE LINE IN THE
WEST. BEHIND THE LINE...EXPECT A BREAK IN THE PRECIP...BUT AM
CONCERNED ACROSS THE CENTRAL PART OF OUR AREA FOR MORE OF A TRAINING
SITUATION AS THE LINE LAYS OVER AND BECOMES MORE PARALLEL WITH THE
FLOW ALOFT. WILL HAVE TO MONITOR THIS CAREFULLY.

PREVIOUS DISCUSSION...
NOT MUCH IN THE WAY OF FORCING THIS AFTERNOON.  A BAND OF MID LEVEL
DEFORMATION AND UPPER LEVEL FORCING MOVES IN WEST TO EAST LATER THIS
EVENING WHICH WILL BRING A BAND OF STORMS OVER NIGHT.  UPPER SUPPORT
LESSENS IN THE MORNING THEN ANOTHER AREA OF WEAK UPPER SUPPORT MOVES
THROUGH TUESDAY AFTERNOON.  AS A RESULT PULSE POPS UP TONIGHT THEN
AGAIN TUESDAY AFTERNOON.  WHILE THERE IS A SLIGHT CHANCE SVR TUESDAY
THE THREAT WILL DEPEND ON HOW MUCH CLOUDS ARE AROUND LETTING SUN ADD
ENERGY.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/...
PERIOD STARTS OUT WITH A SHORTWAVE PUSHING EAST THROUGH THE CWA
WITH SHOWERS AND THUNDERSTORMS CONTINUING THROUGH TUESDAY EVENING.
STILL A CHANCE FOR SEVERE...ALTHOUGH BETTER CAPE AND DYNAMICS
APPEAR TO BE SOUTH OF THE CWA. FRONTAL BOUNDARY WILL BE STALLED
OUT OVER CWA EARLY IN THE PERIOD BEFORE LIFTING BACK NORTH ON
WEDNESDAY AS A WARM FRONT AS AN UPPER LOW OVER THE PLAINS DIGS
SOUTH. THIS WILL PUT THE CWA IN A SOUTHWESTERLY FLOW PATTERN WITH
A TROUGH TO OUR WEST...AND RIDGE TO OUR EAST. MAY HAVE A BIT OF A BREAK
THURSDAY...PARTICULARLY EAST...BEFORE AREA OF LOW PRESSURE TO THE
WEST FINALLY STARTS TO PUSH EAST END OF THE PERIOD.

WATER ISSUES WILL NEED TO BE MONITORED DURING THIS
PERIOD...PARTICULARLY TUESDAY NIGHT AND WEDNESDAY AS FRONTAL
BOUNDARY REMAINS STALLED OVER THE REGION.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
AREA OF LOW PRESSURE TO THE WEST WILL FINALLY PUSH THROUGH FRIDAY
AND FRIDAY NIGHT...KEEPING SHOWERS AND THUNDERSTORMS IN THE
FORECAST. YET ANOTHER SYSTEM PUSHES INTO THE REGION ON SUNDAY AND
POSSIBLY ANOTHER ONE ON MONDAY IN THE NEVER ENDING ACTIVE PATTERN.

&&

.AVIATION /01Z TUESDAY THROUGH SATURDAY/...
00Z TUESDAY THRU 00Z WEDNESDAY...
MAIN FEATURE WILL BE SQUALL LINE THAT WILL MOVE EASTWARD ACROSS THE
AREA LATER THIS EVENING AND EARLY TONIGHT...WITH A BREAK IN THE
CONVECTION BEHIND THE LINE. VFR OUTSIDE OF STORMS...MVFR TO IFR IN
STORMS AND POSSIBLY FOR A COUPLE OF HOURS IN THE COOL POOL OF AIR IN
ITS WAKE BEFORE MIXING OUT.

ONE CONCERN WOULD BE THE LINE LAYING OUT EAST TO WEST ACROSS THE
SOUTHERN HALF OF THE AREA LATE THIS EVENING...WITH POSSIBLE
TRAINING. THIS WOULD CONTINUE THE LOWER FLYING CATEGORIES IN THOSE
AREA WHERE STORMS TRAIN.

AFTER 08Z EXPECT DECREASE IN OVERALL CONVECTION...GENERALLY VFR
CEILINGS EXPECTED AFTER CONVECTION AS WINDS WILL CONTINUE TO MIX THE
ATMOSPHERE. AFTER 15Z CONVECTION INCREASES AGAIN AS UPPER IMPULSES
INTERACT WITH HEATING.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z WEDNESDAY...

FORECAST CONFIDENCE: MEDIUM TO LOW.

ALTERNATE SCENARIOS: LINE OF CONVECTION MAY SLOW AND LAY OUT EAST TO
WEST FOR A WHILE ACROSS THE SOUTHERN HALF OF AREA LATER THIS
