   Day 2 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   1214 AM CST Wed Feb 21 2018

   Valid 221200Z - 231200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Showers and a few thunderstorms are expected from Texas through a
   portion of the Tennessee and Ohio Valleys Thursday.

   ...Texas into the lower Mississippi, Tennessee and Ohio Valleys... 

   Upper pattern will remain characterized by a synoptic trough over
   the western half of the U.S. Thursday. A low-amplitude shortwave
   trough initially over the southern Rockies will eject northeast
   through the Central Plains and middle MS Valley regions and undergo
   deamplification in the process. Quasi-stationary front will reside
   from the Middle Atlantic through the TN and lower MS Valleys to
   south TX Thursday morning. This boundary may retreat some distance
   northwest through the period. An ana-frontal southwesterly flow
   regime will persist with episodes of showers and some thunderstorms
   occurring, primarily within zone of isentropic ascent on the cool
   side of the front. The elevated nature of the convection and weak
   instability should preclude a threat for severe storms.
