Area forecast discussion, Jun 14, 2:24 PM EDT, 17 minutes before
CENTRAL PENNSYLVANIA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
215 PM EDT FRI JUN 14 1996

JUST LIKE CLOCKWORK...SCATTERED SHOWERS AND THUNDERSTORMS ARE
STARTING TO FIRE ACROSS CENTRAL PA BETWEEN 17Z AND 18Z...JUST
LIKE THE LAST 4 DAYS.  MODIFIED PIT SOUNDINGS EVEN A LITTLE MORE
UNSTABLE THAN EARLY MORNING SOUNDING MODIFICATION...WITH LI/S
AROUND -7 AND CAPES IN THE LOW 3000S.  MOS DEWPOINTS LOOK TO BE
AT LEAST 5 DEGREES TOO LOW FOR SOME SPOTS...ACCOUNTING FOR THE
HIER INSTABILITIES.

COLD FRONT IS REALLY TAKING IT/S TIME MOVING INTO THE AREA.  THIS
HAS ALLOWED THE SAME AIRMASS REGIME TO REMAIN OVER THE AREA ALL
DAY TODAY.  CLOUDS HAVE BEEN SPARSE...ALLOWING FOR WARMER TEMPS
THIS AFTERNOON THAN YSTDY.

ACTIVITY IS BEST ORGANIZED OVER NE COUNTIES...IN THE VCNTY OF A
WEAK SPOKE OF UPPER LEVEL SHORTWAVE ENERGY.  BACK OVER CENTRAL
AND WESTERN SECTIONS...CONVECTION IS AGAIN PRETTY RANDOM.
SURFACE MOISTURE CONV CHARTS SHOW BULLSEYE OVER CENTRAL PA AT
18Z...SINKING SOUTH ACROSS SOUTHERN PA BY 00Z.

FRONT WILL CROSS THE AREA OVERNIGHT...THEN ATMOSPHERE SLOWLY
STABILIZES.  GRIDDED DATA SUGGESTS LITTLE IN THE WAY OF CLOUDS
SATURDAY...EXCEPT MAYBE ACROSS SOUTHERN 1/p3 OF STATE.

WILL WRAP THIS UP...AS THINGS HEAT UP HERE AT THE NWSO...
