   MESOSCALE DISCUSSION 0147
   NWS STORM PREDICTION CENTER NORMAN OK
   1139 PM CDT WED MAR 25 2015

   AREAS AFFECTED...SERN OK THROUGH NRN ARK AND NCNTRL TX

   CONCERNING...SEVERE THUNDERSTORM WATCH 8...

   VALID 260439Z - 260615Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 8 CONTINUES.

   SUMMARY...STORMS MOVING THROUGH SERN OK AND NRN AR WILL CONTINUE TO
   POSE A THREAT FOR ISOLATED STRONG TO DAMAGING WIND GUSTS AND LARGE
   HAIL THROUGH 06Z. STORMS DEVELOPING OVER NCNTRL TX MAY POSE A
   MARGINAL THREAT FOR GUSTY WINDS AND HAIL...BUT A WW IS NOT
   ANTICIPATED UNLESS TRENDS DICTATE OTHERWISE.

   DISCUSSION...STORMS CONTINUE DEVELOPING PRIMARILY NORTH OF A COLD
   FRONT FROM NCNTRL TX THROUGH SERN OK INTO NRN AR. AN AXIS OF
   MARGINAL TO MODERATE MUCAPE PERSISTS AHEAD OF THE FRONT WITH THE
   STRONGER INSTABILITY INDICATED OVER NCNTRL TX. SFC-BASED CONVECTIVE
   INHIBITION HAS STRENGTHENED IN PRE-FRONTAL WARM SECTOR SUGGESTING
   STORMS WILL REMAIN CONFINED TO NORTH OF THE FRONT WHERE STRONG
   FORCING FOR ASCENT EXISTS. STRONG EFFECTIVE BULK SHEAR WILL CONTINUE
   TO SUPPORT OCCASIONAL ORGANIZED STRUCTURES INCLUDING MID-LEVEL
   UPDRAFT ROTATION AND BOWING SEGMENTS.

   BACKBUILDING HAS OCCURRED WITHIN PORTION OF THE FRONTAL ZONE OVER
   NCNTRL TX WHERE STORMS WILL PROBABLY REMAIN POORLY ORGANIZED.
   FORECAST SOUNDINGS INDICATE A THERMAL INVERSION BETWEEN 850-700 MB
   IN THE POST-FRONTAL REGION WHICH SHOULD CONTINUE TO LIMIT UPDRAFT
   STRENGTH.
