   Day 2 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   1120 AM CST Sun Nov 18 2018

   Valid 191200Z - 201200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe thunderstorms are not expected on Monday.

   ...Southeast Texas through Louisiana...

   A shortwave trough embedded within a broad upper trough will advance
   east southeast through TX into the lower MS Valley region. Cold
   front should extend from the OH Valley through western TN to along
   the TX coast by 12Z Monday, and will advance southeast during the
   day. South-southwest winds in the 900-850 mb layer will persist
   during the day ahead of the positive-tilt shortwave trough, and this
   will maintain modest isentropic ascent and influx of higher theta-e
   air, contributing to weak instability above the frontal inversion.
   These processes will support a few showers and thunderstorms within
   the post frontal zone over southeast TX during the day and
   eventually into portions of the lower MS Valley during the afternoon
   and evening.

   ...MAXIMUM RISK BY HAZARD...
   Tornado:  <2%     - None
   Wind:     <5%     - None
   Hail:     <5%     - None
