Area forecast discussion, May 8, 3:00 PM EDT, 4 hours 58 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
300 PM EDT WED MAY 8 2002

CURRENT..(TONIGHT AND THURSDAY) FRONTAL BOUNDARY WILL CONT TO MOVE
NORTHWARD THIS EVENING TAKING WITH IT THE RAIN.  OVERNIGHT NOT MUCH
GOING ON UNTIL COLD FRONT PUSHES THRU THURS AFT.  GUID POPS DIFFER A
TAD AND WILL GO WITH THE MAV POPS AS AVN ALONG WITH ETA HAS A GOOD
HANDLE ON THIS SYSTEM. GUID TEMPS ARE ON TRACK AND WILL STAY PRETTY
CLOSE TO THEM IN THE SHORT TERM.  WILL LET FFA EXPIRE AT 8 PM...WITH
NOTHING MAJOR EXPECTED TO DEVELOP OVERNIGHT.  WE WILL LET THE
MIDNIGHT CREW DETERMINE WHETHER THEY NEED AN FFA FOR THURS.

EXTENDED (THU NIGHT-WED)...AVN/ETA SEEM TO BE A FAIRLY GOOD
AGREEMENT WITH TIMING ON FRONT EXIT THE CWA.  NGM IS SLOWER.  AT
THIS TIME HAVE GONE WITH FASTER TIMING BRING FRONT THROUGH LATE DAY
LEAVING A FEW LINGERING SHOWERS EXITING THE EASTERN COUNTIES BY 4Z.
ALSO EXPECT THE COOLER AIR TO FILTER PRETTY QUICKLY AND WITH LITTLE
WRAP AROUND MOISTURE HAVE TRENDED TOWARD AVN GUIDANCE.

HIGH PRESSURE BUILDS IN FRIDAY.  BUT 850 TEMPS AROUND -4 TO -6 BY
THE END OF THE DAY THE MID TO UPPER 60S SEEMS TO BE THE BEST GUESS.

CLOUDS BEGIN TO INCREASE ON SATURDAY...12Z AVN IS FASTER WITH CLOUDS
AND RH THAN 00Z RUN.  WILL HOLD OFF ON PCPN UNTIL THE NIGHT TIME
HOURS...BUT WITH OVER RUNNING PCPN THE MODELS ARE OFTEN TOO SLOW TO
BREAK OUT PCPN.

THE WARM MOVES OVER THE REGION AND STALLS AS FRONT BECOMES PARALLEL
TO THE UPPER LEVEL FLOW.  WITH THE SURFACE WINDS STRONG OUT OF THE
SOUTH AND WAVES OF LOW PRESSURE MOVING ALONG THE FRONT SUNDAY THRU
MON...THE CHANCE FOR HEAVY RAIN IS POSSIBLE.  WITH THE GROUNDS
ALREADY NEARLY SATURATED...EXPECT THAT SOME FLOODING WILL OCCUR WITH
THIS SYSTEM AS WELL.

COLD FRONT FINALLY CLEARS THE REGION MONDAY NIGHT...BRING A FEW DRY
DAYS FOR THE MIDDLE OF THE WEEK.  TEMPERATURE GUIDANCE FROM MEX
LOOKS TO BE REASONABLE.
