AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
215 PM EDT FRI JUN 22 2001

SOME PORTIONS OF THE FINGER LAKES HAVE BROKEN OUT INTO THE SUN TODAY AND BECOME
UNSTABLE. LINE OF CONVECTION ENTERING THE WESTERN CWA ATTM WILL BE MOVING INTO
THIS UNSTABLE AMS. AREAS TO THE SOUTH ARE POPPING ATTM AS WELL SO IT LOOKS LIKE
THE THREAT OF SVR WITH FFW POTENTIAL WILL CONTINUE.

SFC LOW NORTH OF LAKE ONTARIO IS PROGGED TO CONTINUE MOVING NORTH AND CONTINUE
SWINGING A COLD FRONT...CURRENTLY MOVING INTO THE WRN CWA...SLOWLY INTO THE
REGION TONIGHT. MODELS DEVELOP A WAVE ALONG THE SOUTHERN PORTION OF THE FRONT
AND SLIDE IT THROUGH THE SERN ZONE TONIGHT. LAPS DATA SHOWS THIS LOW FORMING
ATTM SO HAVE SOME CONFIDENCE IN THIS SOLUTION.

BELIEVE PCPN WILL CONTINUE TO FILL IN TONIGHT WITH TRAINING PCPN A BIG CONCERN.
AREA FROM THE POCONOS TO THE CATSKILLS LOOK TO SEE THE MOST PCPN AS THE WAVE
SLIDES ALONG THE FRONT TONIGHT. ALTHOUGH THE FRONT IS MOVING INTO THE WRN
CWA...WITH UPPER TROF CLOSING OFF AND RETROGRADING TOWARD TN AND WAVE
DEVELOPING ALONG THE FRONT...BELIEVE THINGS WILL SLOW DOWN ENOUGH TO KEEP PCPN
ACROSS ALL ZONES TONIGHT. FFA WILL BE EXTENDED FOR THE ENTIRE CWA WITH THIS
PACKAGE.

PCPN WILL GRADUALLY TAPER OFF FROM WEST TO EAST TOMORROW BUT ERN ZONES WILL BE
WET INTO TOMORROW EVENING. WILL GO DRY FOR MOST OF SATURDAY NIGHT AND LEAN
TOWARD AN OPTIMISTIC PS FOR SUNDAY.

MO9S TEMPS SEEM OK SO WILL STAY CLOSE.

.BGM...FLASH FLOOD WATCH FOR AREAS ALONG AND WEST OF I-81.
