UPR LOW CONTINUES A SLOW EWD TREK INTO SWRN IND AT MID-AFTN.  THERE
APPEARS TO BE A MODEST SPEED MAX MOVING QUICKLY TOWARD THE KY
COALFIELDS IN WATER VAPOR IMAGERY.  THE ENHANCED ASCENT ASSOCD WITH
THIS FEATURE IN COMBINATION WITH MORE SIGNIFICANT COOLING ALOFT
BEGINNING TO SPREAD EWD WILL LIKELY MAKE FOR A MORE FAVORABLE
ENVIRONMENT FOR TSTMS THROUGH LATE AFTN.

EARLIER BANDS OF CONVECTION EFFECTIVELY MOISTENED THE BOUNDARY LAYER
WITH A NARROW ZONE OF LWR-MID 50S SFC DEW POINTS NOTED ALONG/AHEAD
OF A FRACTURED OCCLUDED FRONT.  IN WAKE OF THE EARLY CONVECTION...A
BRIEF PERIOD OF INSOLATION HAS CONTRIBUTED TO WARMING SFC
TEMPERATURES WITH SBCAPES APPROACHING 500 J/KG ALONG THE APPALACHIAN
CREST NWWD INTO THE ERN KY COALFIELDS AND THE SWRN LOWLANDS OF WV.


TSTMS ARE EXPECTED TO DEVELOP VCNTY THE OCCLUDED FRONT FROM NERN
TN/NWRN NC NWWD INTO ERN KY AND SWRN WV THEN MOVE NWD TOWARD THE
MID-OH VLY WITH TIME.  GIVEN COOLING TEMPERATURES ALOFT...ISOLD MORE
VIGOROUS STORMS MAY PRODUCE HAIL ALONG WITH GUSTY WINDS.

A WW IS NOT ANTICIPATED GIVEN THE MARGINAL INSTABILITY AND ISOLD
NATURE TO ANY SVR POTENTIAL.
