SATELLITE ANALYSIS AND TRENDS...IR IMAGERY SHOWS WARM-TOPPED CELLS
CONTINUING TO COOL AND EXPAND ALONG AN E-W ORIENTED LINE FROM THE
UPPER OHIO RIVER VALLEY, ACROSS AND ALONG THE MASON-DIXON LINE,
INTO N. CNTRL MARYLAND.  OF IMMEDIATE CONCERN IS THE REPEATING CELLS
PUSHING THRU NORTHERN WV AND WESTERN MD.  ESTIMATED RAIN RATES UP
TO .6-.8" PER HALF-HOUR MAY BE AUGMENTED BY FAST EASTWARD MOTION BUT
REPETITION WILL ALLOW SOME LOCALES TO REACH FFG VALUES IN A SHORT TIME.
SOUNDER PW'S ARE INCREASING AND APPROACHING 2.00" AND TD'S NEAR AND ABOVE
70 WILL CREATE A VERY MOIST ENVIRONMENT FOR THE STORMS TO FEED FROM.
CLEAR SKIES AND GOOD LI'S MAY ALLOW FOR MORE SEVERE-TYPE WX AS THE LINE
PUSHES EASTWARD INTO N. VA AND CNTRL MD BUT MULTIPLE OUTFLOWS WILL CREATE
MERGER POSSIBILITIES THAT MAY NOT BE READILY DETECTABLE IN IMAGERY DUE
TO EXPANSION OF DEBRIS CLOUDS.
