Flash Flooding and Hail in Virginia, July 3, 2002

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG, VA
1050 AM EDT WED JUL 3 2002

HAVE A SENSE THAT SINCE THE MTNS SAW ALMOST ALL THE ACTION
YDAY...THE EAST WILL SEE MORE TODAY.

MESOETA WANTS TO DEVELOP CONVECTION ON SFC TROF OFF THE NJ COAST
THIS MORNING AND PUSH IT WEST INTO THE FA LATE TODAY...ALTHOUGH IT
WANTED TO GET IT STARTED TOO EARLY...WHICH HURTS ITS CREDIBILITY.
HOWEVER WV DOES SHOW A S/WV PUSHING INTO THE JERSEY COAST WITH A
WEAK BNDRY SHOWING UP ON VISIBLE OFF THE DELMARVA.  MODIFIED CAPES
ACROSS NE VA THIS AFTN COULD BE AS HIGH AS 4500-5000...WHERE ATMOS
DID NOT GET WORKED OVER AT ALL YDAY.  SO IF CONVECTION DEVELOPS TO
OUR NE...STEERING FLOW WOULD LIKELY TRACK IT IN THIS DIRECTION.  SO
WILL BUMP EASTERN POPS UP A NOTCH.

WILL ALSO RAISE TEMPS A LTL.  WILL UPDATE SPS HIGHLIGHTING THE HEAT
IN THE EAST.

*******************
PREVIOUS DISCUSSION
*******************

A SIMILAR DAY TO YESTERDAY EXPECTED FOR TODAY...ALTHOUGH CONVECTION
WILL NOT BE QUITE AS WIDESPREAD.

UPPER RIDGE DISPLACED A BIT TO THE NORTH...WITH WEAK IMPULSES
FORECAST TO ROTATE SOUTHWESTWARD DOWN EAST SIDE.  STRONGEST VORT MAX
SEEN ON WV IMAGERY SOUTH OF CAPE COD AND TRACKING SOUTHWEST.  THIS
FEATURE LIKELY TO INFLUENCE CONVECTION ACROSS THE EASTERN HALF OF
THE CWA FROM LATE AFTERNOON INTO THE EVENING AS IT CONTINUES TO
SLIDE UNDER THE UPPER RIDGE.  BUFR CAPES RANGING 2K-3K J/KG...
SIMILAR TO YESTERDAY.  SPC HAS MUCH OF THE FA OUTLOOKED AND THIS
SEEMS REASONABLE AFTER ISSUING 30+ WARNINGS TUESDAY.

TONIGHT ATMOS STABILIZES AFTER LOSS OF HEATING...WITH TSTMS
DISSIPATING BY MIDNIGHT.

FOR THE 4TH...SURFACE TROUGH APPEARS TO BE TRYING TO SET UP A BIT
FARTHER TO THE EAST...AND SYNOPTIC SCALE FORCING APPEARS TO BE LESS
ORGANIZED...BUT WITH UNSTABLE AIRMASS IN PLACE AND POTENTIAL FOR
ADDITIONAL WEAK DISTURBANCES WILL CONTINUE CHC POPS ALL LOCATIONS.

AVN CONTINUES TO BRING FRONT SOUTHWARD INTO THE FA ON FRIDAY.
CANADIAN UPPER LOW MAY BE OVERDONE...BUT 1028 HIGH SHOULD BE
SUFFICIENT TO AT LEAST FORCE THE FRONT INTO THE FA.  CURRENT
FORECAST IS DRY...BUT AFTER SOME DISCUSSION WITH SURROUNDING OFFICES
I WILL ADD 30 POPS TO THE SOUTHERN THIRD OF THE FA FOR THE AFTERNOON
AND EVENING.

TEMPWISE HAVE GONE CLOSER TO FWC NUMBERS AS AVN MOS CONTINUES TO RUN
ON THE COOL SIDE WITH MAXES.

SEVERE WEATHER OUTLOOK
NATIONAL WEATHER SERVICE BLACKSBURG VA
1155 AM EDT WED JUL 3 2002

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
EVENING...

THUNDERSTORMS WILL DEVELOP ONCE AGAIN DURING THE MIDDAY AND
AFTERNOON ACROSS SOUTHEASTERN WEST VIRGINIA...SOUTHWESTERN VIRGINIA
AND NORTHWESTERN NORTH CAROLINA.  AS AN UPPER LEVEL DISTURBANCE
CROSSES THE REGION...SOME OF THE THUNDERSTORMS MAY BECOME SEVERE
WITH DAMAGING WINDS AND LARGE HAIL.

IN ADDITION...THE ATMOSPHERE REMAINS VERY MOIST.  VERY HEAVY RAIN
WILL OCCUR WITH SOME OF THE STORMS.  FLASH FLOODING IS A POSSIBILITY
IN THE HEAVIER RAIN...ESPECIALLY WHERE HEAVY THUNDERSTORM RAINS
OCCURRED DURING TUESDAY AFTERNOON AND EVENING.

SKYWARN MAY NEED TO BE ACTIVATED THIS AFTERNOON.
