FLASH FLOOD WARNING
NATIONAL WEATHER SERVICE STATE COLLEGE PA
855 AM EST SAT NOV 8 1997
 
THE NATIONAL WEATHER SERVICE IN STATE COLLEGE HAS EXTENDED THE
FLASH FLOOD WARNINGS UNTIL 1100 AM EST FOR PEOPLE IN THE
FOLLOWING LOCATIONS.
 
IN  PENNSYLVANIA
 
   ...BEDFORD COUNTY...BLAIR COUNTY...CAMBRIA COUNTY
   ...WESTERN CLEARFIELD COUNTY...FRANKLIN COUNTY...FULTON COUNTY
   ...HUNTINGDON COUNTY...SOMERSET COUNTY
 
HEAVY RAINS HAVE DIMINISHED TO LIGHT RAIN AND DRIZZLE THIS MORNING.
BUT...RECENT HEAVY RAINS HAVE PRODUCED MANY FLOODED ROADWAYS AND CAUSED
SMALL STREAMS AND CREEKS TO OVERFLOW THEIR BANKS. AS A RESULT... FLOOD
WARNINGS WILL CONTINUE UNTIL FLOOD WATERS CAN RECEDE OR UNTIL 11 AM.
 
DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE
ROADWAY.  THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO
CROSS SAFELY.  VEHICLES CAUGHT IN RISING WATER SHOULD BE
ABANDONED QUICKLY.  MOVE TO HIGHER GROUND.

CENTRAL PENNSYLVANIA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
300 AM EST SAT NOV 8 1997

ALREADY HAD EXTENSIVE PHONE COORD WITH PHI AND PIT AS PER FORECAST
FOR THE MORNING.

HEAVIEST RAIN HAS NOW EXITED THE CTP CWA INTO PIT AREA.  ANOTHER
BATCH OF MODERATE TO HEAVY RAIN DEVELOPING IN THE LOWER SUSQUEHANNA
VALLEY ATTM.

UPPER LEVEL LOW HAS REMAINED NEARLY STATIONARY DURING THE LAST 12
HOURS...AND HAS SET UP A STEADY-STATE EASTERLY FLOW OF MOISTURE OFF
THE ATLANTIC INTO SOUTHERN PA.  LOW LEVEL TROF/CONVERGENCE ZONE HAS
FOCUSED HEAVIEST RAIN ACROSS THE SOUTH CENTRAL MTS AND LAUREL
HIGHLANDS.

IF WE BELIEVE THE MODELS THIS MORNING...THE LOW LEVEL JET WILL
FINALLY SHIFT NORTHWARD TODAY.  ACTUALLY...JET AND FORCING WILL
ROTATE DURING THE DAY...CHANGING THE ORIENTATION OF PCPN FROM E-W
OVER SOUTHERN PA TO A NE SW ORIENTATION LATER TODAY.  THIS WAS
SUPPOSED TO HAPPEN DURING THE DAY FRIDAY...BUT UPPER LEVEL SYSTEM
DID NOT MOVE.  WV IMAGRY STILL NOT INDICATING ANY MOVEMENT OF THE
UPPER CIRCULATION...SO TODAYS MODELS AGAIN MAY BE TOO FAST MOVING
PCPN OUT.

THEREFORE DISCOUNT PALTRY NGM PCPN NUMBERS...AND SUGGEST AT LEAST
ANOTHER .50 INCHES IN LOWER JUNIATA RIVE(R.  FFA SHOULD BE CONTINUED
INTO MORNING AS THEY STAND.
