What forecasters said that day

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Binghamton, NY wrote its last area forecast discussion before this flash flood warning went out at Jun 23, 11:00 AM EDT, 1 hour 41 minutes earlier.

Area forecast discussion, Jun 23, 11:00 AM EDT, 1 hour 41 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
1055 EDT SAT JUN 23 2001

WE ONLY MADE MINOR CHANGES TO EXISTING FORECAST.

MAIN BAND OF HEAVY RAIN LATE THIS MORNING CONTINUES TO AFFECT AREAS
NEAR THE INTERSTATE 81 CORRIDOR FROM THE TWIN TIERS NORTHWARD
TOWARDS SYRACUSE AND THE MOHAWK VALLEY.  OUR SHORT RANGE COMPUTER
MODELS INDICATE THAT THE BEST LIFT AND SUPPORT FOR ADDITIONAL HEAVY
RAINS WILL SLOWLY SHIFT EASTWARD THIS AFTERNOON AND EVENING TOWARDS
THE WESTERN CATSKILLS AND THE POCONOS.  GIVEN SLOW MOVEMENT OF
SYSTEM, RECENT HISTORY, AND GOOD LIFT PROGGED DURING THE AFTERNOON,
CONTINUING THE FLASH FLOOD WATCH ALL AREAS IS A GIVEN.  HOWEVER, THE
MAIN THREAT FOR ADDITIONAL HYDRO RELATED PROBLEMS LOOKS TO BE FROM
I-81 ON EAST.

SATELLITE LOOP THIS MORNING SHOWS SOME THINNING OF THE CLOUDS EAST
OF THE MAIN SURFACE BOUNDARY ACROSS NORTHEAST PA.  THIS MAY RESULT
IN SOME INSOLATION WHICH COULD HELP CONVECTION FIRE THIS AFTERNOON.
SINCE MID LEVEL WINDS ARE NEAR 40 KNOTS IN THIS AREA, ANY STORMS
WOULD HAVE TO BE WATCHED.  OUR GUT FEELING, THOUGH, IS THAT CLOUDS
WILL KEEP ENOUGH OF A LID ON INSTABILITY TO KEEP THUNDERSTORMS
FAIRLY ISOLATED IN NATURE.

HIGH TEMPERATURES WERE RAISED SLIGHTLY IN OUR SOUTHEASTERN ZONES.

.BGM...FLASH FLOOD WATCH CONTINUES FOR CENTRAL NY AND NORTHEAST
PA.
