SATELLITE ANALYSIS AND TRENDS...RADIOSONDE AND GOES SOUNDER PW ANALYSIS
SHOWED A SHARP PW GRADIENT BETWEEN 1.25 INCH OR LESS VALUES FROM SW PA/
 OHIO NORTHWARD AND MAX VALUES OF CLOSE TO 2.0 INCHES IN E KY.  THIS GOES
 ALONG WITH BAROCLINIC LEAF CLOUD SIGNATURE N KY THRU S OH/W HALF OF
 WEST VA AND COULD ALLOW FOR NARROW STEADY VERY HVY RAIN FROM ALONG THE
 KY-OHIO BORDER THRU S OHIO INTO WESTERN WV SPILLING OVER INTO SW PA.
IF THIS GRADIENT SHARPENS A LITTLE MORE...THIS AREA COULD SEE 1.0 INCH
PER 3HR AMOUNTS AND POSSIBLY ANOTHER 1.0-1.5 INCH PER 3HR AMOUNTS CLOSE
BY IN THE 03-06Z TIME PERIOD.  IT WOULD BE A VERY NARROW AREA POSSIBLY
SEEING THOSE TYPES OF AMOUNTS AS CONVECTIVE BANDS/OVERSHOOTING TOPS
GETTING TO FAR NORTH INTO LOWER PW AIR WILL ONLY RESULT IN LIGHT OR
SHORT PERIODS OF MODERATE TO HVY RAIN.  SO CONCENTRATION AND FOCUS ON
OVERRUNNING AREA FROM S CENTRAL/SE OHIO THRU W WEST VA INTO SW PA AND
COULD EXTEND EVEN MORE NARROW INTO C PA FOR A TIME  AND BACK INTO MOIST
BULGE TO C KY AND EXT S INDIANA NEAR THE OHIO RIVER.
WILL CONTINUE TO MONITOR...SEE ANALYSIS GRAPHIC ON HOME PAGE AT ADDRESS
