SQUALL LINE HAS MATURED ALONG SURGING COLD FRONT WITH DAMAGING WINDS
NOW OBSERVED WITH CONVECTION EXTENDING INTO THE ARKLATEX REGION. 
BOUNDARY LAYER MOISTURE HAS STEADILY INCREASED AHEAD OF THE LINE
WITH MID 50S DEW POINTS INTO SCNTRL AR.  IN ADDITION...A NARROW AXIS
OF STEEPER LAPSE RATES/HIGHER INSTABILITY HAS DEVELOPED FROM THE
HILL COUNTRY OF TX...NEWD INTO AR.  GIVEN THE FOCUSED HEIGHT FALLS
OCCURRING ACROSS THIS REGION...IT APPEARS LARGE SCALE SUPPORT WILL
CONTINUE WITH THIS SQUALL LINE AS IT PROPAGATES SEWD AT ROUGHLY
30-35KT.  OTHER PRE-FRONTAL SHOWERS ARE DEEPENING OVER THE COASTAL
PLAINS OF TX NEAR CLL. THIS ACTIVITY SHOULD CONTINUE TO STRENGTHEN
BEFORE COLD FRONTAL CONVECTION OVERTAKES NEW DEVELOPMENT...FORCING
STORM MERGERS INTO LINEAR ECHOES.  DAMAGING WINDS SHOULD BE THE MAIN
SEVERE THREAT...ALTHOUGH HAIL IS POSSIBLE WITH SRN MOST CONVECTION.
