SATELLITE ANALYSIS AND TRENDS...VIS IMAGERY SHOWS NUMEROUS SMALL CELLS
OVER THE HIGHER TERRAIN OF THE SRN APPALACHIANS THAT ARE MOVING SLOWLY
OR ARE NEARLY STNRY PRODUCING HVY RAINS. CELLS HAVE BEEN MOSTLY WARM
TOP WITH COLDEST TEMPS ONLY NOW BREAKING INTO -60C. DEWPTS IN THE HIGH
60/LOW 70S AND PW VALUES OF 1.6-1.8" GIVEN BY GOES SOUNDER/GPS VALUES
HAVE PROVIDED A MOIST ENVIRONMENT FOR STORMS TO BE ABLE TO PRODUCE HVY
RAINS WITH THEIR SLOW MOVEMENT. BEST INSTABILITY AND POOL OF HIGHEST
MOISTURE EXISTS FROM S CENTRAL TN TO SWRN VA/EXTREME SE WV..JUST W OF
THE HIGHEST POINTS ALONG THE MTNS IN W NC/SW VA. THESE STORMS HAVE BEEN
SEEN PULSING ON VIS IMAGERY/RADAR AT TIMES SO IT IS HARD TO TELL HOW LONG
THEY WILL LAST OVER ANY PARTICULAR AREA BEFORE THEY DIE OFF. OBJECTIVE
ANALYSIS SHOWS A SMALL AREA OF SFC MOISTURE CNVG OVER NW NC/SW VA AND
IT APPEARS AS THOUGH A BNDRY STRETCHING FROM KAVL TO KTNB TO KHLX IS
MOVING NWWD WHILE SFC WINDS OVER SE KY/EXTREME SW VA ARE WRLY. ALSO
CELLS ARE GROUPED OVER E CENTRAL TN ALONG THE HIGHER TERRAIN SLOPING
NEWD INTO SE KY/SW VA/S WV. FFG IS SLIGHTLY LOWER OVER TN/KY/SW VA BUT
STILL CANNOT RULE OUT HVY RAINS FOR MTNS OF NC WITH LITTLE MOVEMENT
OF CELLS EXPECTED. RAINFALL RATES OF 0.5-1"/HR ARE POSSIBLE BUT SINCE
CELLS ARE NEARLY STNRY RAINS MAY ACCUMUALTE QUICKLY. LOSS OF DAYTIME
HEATING SHOULD START TO WEAKEN THESE CELLS THOUGH THROUGH EVENING. SEE
WEB ADDRESS BELOW IN ABOUT 5-10 MIN FOR GRAPHIC.
