Flash Flood Warning 55, NWS State College, PA

CENTRAL PENNSYLVANIA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
145 PM EDT WED JUN 12 1996

HERE WE GO AGAIN?   LATEST 88D LOOP SHOWING SCATTERED SHOWERS AND
THUNDERSTORMS BEGINNING TO DEVELOP ACROSS THE CWA.  MOST OF THE
ACTIVITY ATTM IS EAST OF UNV...BASICALLY OVER THE PHI COUNTIES IN
OUR CWA.  A DETAILED SURFACE ANALYSIS SHOWS WHAT COULD BE A WEAK
BUBBLE HIGH OVER WESTERN PA ATTM.  PERHAPS COINCIDENTALLY...
SHOWERS AND STORMS ARE DEVELOPING EAST OF THE "HIGH" WITH NO
ACTIVITY FROM BFD TO AOO.

NO SATELLITE IMAGERY ON RAMSDIS OR INTERNET...HAD TO RELY ON
MICROSWISS.  THE LATEST VISIBLE LOOP SEEMS TO INDICATE A COMMA
HEAD MOVING INTO WV ATTM.  THIS CAN BE SEEN WITH SOME
ORGANIZATION TO RAIN/SHOWERS OVER EASTERN WV ATTM.  MODELS SEEM
TO INDICATE THAT THIS SHORTWAVE WILL ROTATE NORTHEAST ACROSS
CENTRAL AND EASTERN PA.  MOISTURE CONVERGENCE WOULD ALSO SUGGEST
THAT CENTRAL AND EASTERN AREAS WOULD BE UNDER THE GUN FOR THE
MOST ORGANIZED CONVECTION.

WITH PCPL WATERS RUNNING 1 TO 1.25 INCHES ACROSS THE REGION...AND
SLOW MOVEMENT OF THUNDERSTORMS...WOULD NOT BE SURPRISED TO BE
WORRIED ABOUT FLOODING THIS EVENING...ESPECIALLY FOR SMALL
STREAMS/CREEKS.  PHL/PIT...ANY THOUGHTS OF FLOOD WATCHES FOR THE
REST OF THE AFTERNOON AND EVENING?  UPPER FLOW A LITTLE FASTER
THAN YESTERDAY...SO WOULD EXPECT A LITTLE FASTER MOVEMENT ON THIS
AFTERNOON/S STORMS.  FFG WAS EXCEEDED YESTERDAY IN SEVERAL
LOCATIONS.  STILL HAVE CXURRENT FFW IN FRANKLIN COUNTY...AND WITH
ANY ADDITIONAL RAIN...THIS MAY NEED TO BE EXTENDED.
