   STRONG PV-ANOMALY WAS MOVING INTO E TX/SRN OK AT DAYBREAK.  INTENSE
   LARGE-SCALE AND MESOSCALE FORCING ALONG THE ADVANCING COLD FRONT HAS
   RESULTED IN AN INTENSIFYING SQUALL LINE OVER FAR E TX.  12Z SHV
   SOUNDING SUGGESTS THAT STORMS ARE LIKELY SLIGHTLY ELEVATED WITH
   ABOUT AN 800 METER STABLE BOUNDARY LAYER.  HOWEVER...RECENT
   STRENGTHENING OF STORMS AND MOISTENING OF THE BOUNDARY LAYER
   IMMEDIATELY AHEAD OF THE LINE MAY BE SUFFICIENT TO ALLOW DAMAGING
   WIND GUSTS TO ACCOMPANY THE STORMS.  MEANWHILE...E OF THE LINE...E-W
   ORIENTED WARM ADVECTION DERIVED BANDS OF STORMS WERE
   DEVELOPING...PRIMARILY OVER SRN AR AND NRN LA.  MID-LEVEL LAPSE
   RATES AND EFFECTIVE DEEP LAYER SHEAR WERE SUFFICIENT FOR HAIL
   PRODUCTION WITH THESE STORMS.
   
   IF STORMS CONTINUE TO THRIVE/INTENSIFY...PARTICULARLY THE SQUALL
   LINE...A WW MAY BECOME NECESSARY.
