EXTENSIVE SQUALL LINE WITH TRAILING STRATIFORM REGION WAS CROSSING
THE CNTRL APPALACHIANS EARLY TODAY. STRONG DEEP LAYER AND MESOSCALE
ASCENT WAS BEING MAINTAINED ALONG THE LINE BY FAST MOVING CONVECTIVE
OUTFLOW AND BROADLY DIFFLUENT 60-70KT FLOW WITHIN EXIT REGION OF MID
LEVEL JET. MOTION ALONG THE LINE WAS GENERALLY EAST AT BETWEEN
45-50KT AND EXPECT THIS SPEED TO BE MAINTAINED INTO THE ERN SECTIONS
OF WATCHES 348 AND 349 OVER THE NEXT HOUR AND A HALF. DAMAGING WINDS
APPEAR TO BE THE PRIMARY THREAT FROM THIS CONVECTION AS IT DEVELOPS
EWD. HOWEVER...TORNADO POTENTIAL WILL CONTINUE TO EXIST INVOF LINE
INTERSECTIONS/WAVES SUCH AS THE ONE MOVING ACROSS MONROE COUNTY IN
ERN TN AT THIS TIME. ADDITIONALLY...STORMS WITH SUPERCELL STRUCTURE
ARE APPARENT AHEAD OF THE LINE...OVER SWRN VA. THIS DEVELOPMENT
APPEARS TO BE OCCURRING ALONG OR NEAR THE WARM FRONT. IF CONVECTION
MAINTAINS CURRENT INTENSITY AND SPEED...WHICH APPEARS POSSIBLE...NEW
WATCHES MAY BE NEEDED ACROSS PORTIONS OF VA AND NC LATER THIS
MORNING.
