SATELLITE ANALYSIS AND TRENDS..VERY WARM CLOUD TOPS ON IR ARE CURRENTLY
PRODUCING MOD TO OCCASIONALLY HVY RAINS ACROSS EXTREME E KY AND ERN
OH. COLDEST CLOUD TOP TEMPS ARE ONLY AT -45C NEAR TO PA/OH BORDER AND
ARE AS WARM AS -25 TO -30C FARTHER S IN E KY BUT STILL PRODUCING MOD
RAINFALL. COLDER HIGH CLOUDS OUT AHEAD OF THE HEAVIEST RAINFALL..CURRENTLY
OVER WV/WRN VA/W NC ARE PRODUCING VERY LITTLE RAINFALL AS BEST FORCING
IS STILL BACK ALONG THE WV/OH BORDER INTO W CENTRAL PA WHERE MULTIPLE
SFC LOWS APPEAR TO BE LINED UP FROM SW-NE. AM CONCERNED ONLY BECAUSE
CELLS LOOK AS THOUGH THEY MAY TRAIN ACROSS SW/W CENTRAL PA AND PARTS OF N
WV/SE OH THAT HAVE MUCH LOWER 1 AND 3 HR FFG. WITH ORAGRAPHICS ENHANCING
THE RAIN RATES AND WEAK SW FLOW SEEN IN LATEST SFC WIND PLOT..BELIEVE
RATES OF .25-.5"/HR ARE LIKELY ACROSS THIS AREA WITH SOME LOCAL SPOTS
RECEIVING 1-1.5" AMOUNTS IN THE NEXT 2-3 HRS. DEWPTS IN THE MID 50'S IN
SW PA/NRN WV WILL ALLOW FOR THESE RAIN RATES TO CONTINUE AS THE CELLS
CONTINUE MOVING NEWD AND THE ENTIRE LINE SHIFTS SLOWLY EWD. JUST IN
2345Z IR IMAGE SHOWS SOME ADDITIONAL CLOUD TOP COOLING/EXPANSION NEAR
THE OH/WV BORDER ENHANCING RAIN RATES OVER THE AREA. SEE WEB ADDRESS IN
ABOUT 10-15 MIN FOR GRAPHIC.
