SATELLITE ANALYSIS AND TRENDS...LATEST WV IMAGERY INDICATES BROAD TROF
AXIS LOCATED OVER IN/OH WITH AN INITIAL EMBEDDED S/WV IMPULSE MOVING NEWRD
THRU SRN PA/EXT WRN MD. THIS MID-UL FORCING FOR ASCENT COMBINED WITH LOW
LVL CONVERGENCE INVOF FRNTL BNDRY LOCATED ACROSS CENT/ERN PA FROM NEAR
KUNV TO THE ENE ACROSS NRN NJ INTO SRN NY/SWRN CT NEAR KBDR HAS ALLOWED
FOR RECENT CONVECTIVE DEVELOPMENT OVER THE LAST FEW HRS ACROSS ERN PA
CLOSE TO BEST OBJECTIVELY ANALYZED MOISTURE CONVERGENCE CLOSE THE THE
FRNTL BNDRY NEAR KRDG. BEST INSTABILITY IS ACROSS SRN PA INTO MD WITH
MUCAPE VALUES UPWARDS OF 2000 J/KG PER SPC MESOANALYSIS. LATEST BLENDED
TPW IMAGERY ALSO INDICATES RELATIVE PW MAX NEAR 1.5"  IN SAME AREA AS
INSTABILITY MAX ACROSS SRN PA/MD...WITH LATEST GPS DATA INDICATING PWS
RIGHT NEAR 1.7" OUT OF KBWI. THE MOISTURE/INSTABILITY MAXIMA AXIS WILL
BE ABLE TO ADVECT NNE OVER NEXT SEVERAL HRS INTO ERN PA/WRN NJ WITH
S/SSW FLOW AT 20-30 KTS FROM REGIONAL VWPS AT 925 AND 850 MB.
.
ANTICIPATE FURTHER CONVECTIVE DEVELOPMENT OVER NEXT FEW HRS AS
UPPER LVL SUPPORT FROM S/WV AS WELL AS UL DIVERGENCE INDICATED FROM
EXPERIMENTAL CIMMS/NOAA DERIVED WINDS CONTINUES TO INTERACT WITH LOW LVL
CONVERGENCE. ACROSS THE REGION. MEAN FLOW THRU THE CLOUD BEARING LAYER IS
GNRLY STRONG AT 30-40 KTS FROM THE SW...BUT UNIDIRECTIONAL SW FLOW THRU
MID-UPPER LVLS WOULD SUPPORT A MAIN THREAT FROM TRAINING CONVECTION ACROSS
ERN PA/NWRN NJ AND EXTENDING DOWNWIND POSSIBLY INTO SRN NY.  STRONG INFLOW
FROM THE S/SSW FAVORABLY ORIENTED TO THE MOISTURE/INSTABILITY AXIS WOULD
ALSO SUGGEST BRIEF PERIODS OF BACKBUILDING ARE POSSIBLE ESPECIALLY IN
ERN/SERN PA. EVEN AFTER THIS INITIAL S/WV MOVES OVER THE REGION...WILL
STILL NEED TO MONITOR EMBEDDED S/WVS FURTHER UPSTREAM THAT MAY CONTINUE
TO ALLOW FOR CONVECTIVE DEVELOPMENT ACROSS THE AREA. PLEASE REFER TO
WPC MPD #0281 FOR MORE INFORMATION ABOUT HVY RAIN THREAT AND CONCERN
FURTHER W INTO WRN PA/ERN OH.

AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
