PRIMARY FORCING FOR ASCENT WAS RAPIDLY PROGRESSING NEWD AWAY FROM
THE MID-ATLANTIC THIS EVENING. NONETHELESS...SEGMENTED BANDS OF
TSTMS CONTINUE TO THRIVE IN AMPLE BUOYANCY AND 50 KTS OF VERTICAL
SHEAR ACROSS FAR ERN NC AND SERN VA. OVERALL SVR THREAT WILL BEGIN
TO WANE THROUGH MID-EVENING AS BOUNDARY LAYER COOLS AND
REDEVELOPMENT OF TSTMS ALONG THE PRIMARY COLD FRONT DOES NOT APPEAR
LIKELY. AS A RESULT...WILL MAINTAIN LOW PROBABILITIES FOR A BRIEF
TORNADO/WATERSPOUT OR DMGG WIND GUST...BUT SMALL TEMPORAL/SPATIAL
AREA ARGUES AGAINST SUSTAINING A CATEGORICAL SLIGHT RISK.

EVENING. MEANWHILE...A SUB-SEVERE LINEAR MCS WILL CONTINUE MOVING
SLOWLY SEWD THROUGH CNTRL FL TONIGHT. REGION WILL BECOME FURTHER
REMOVED FROM STRONGER ASCENT/WIND FIELDS WITH TIME THIS EVENING AND

KY...BEING AIDED BY COLD TEMPERATURES ALOFT AND EXIT REGION OF A WLY
MID-LEVEL JET. ISOLD HAIL MAY ACCOMPANY THE STORMS THROUGH
MID-EVENING AS THEY APPROACH THE TN BORDER...BUT EXPECT STORMS TO
DIMINISH AS THE BOUNDARY LAYER COOLS.
