CONTINUES.

QUASI-LINEAR MCS CONTINUES TO DEVELOP EWD/SEWD AROUND 30KT AND WILL
MOVE TO THE ERN EDGE OF WATCH 177 WITHIN THE HOUR. THIS SYSTEM HAS
LEFT A WELL-FORMED AND EXTENSIVE COLD POOL IN ITS WAKE ACROSS MUCH
OF AR. FORCED MESOSCALE ASCENT ASSOCIATED WITH THE COLD POOL
DYNAMICS...COUPLED WITH FAVORABLE LARGE-SCALE BACKGROUND

ACROSS WRN TN AND NRN MS NEXT 1-3 HOURS. GREATEST SEVERE WEATHER
THREAT SHOULD CONTINUE TO BE STRONG/DAMAGING WIND GUSTS NEAR APEX OF
BOWING STRUCTURES ALONG THE LINE. DIURNAL COOLING  AND GRADUAL

CONVECTIVE INTENSITY AS THE COMPLEX SPREADS EAST TOWARD AL.
THUS...LOCAL EXPANSION OF WATCH 177 ACROSS PARTS OF TN/MS REMAINS
POSSIBLE BUT A NEW WATCH WILL PROBABLY NOT BE NEEDED TO THE EAST OF
EXTENDED PORTIONS OF WATCH 177.
