   Day 3 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   0130 AM CST Tue Feb 20 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 Valley 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. on Thursday. A low-amplitude shortwave
   trough initially over the southern Rockies will eject northeast
   through the Central Plains and middle MS Valley regions. 
   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 during the period, but
   in general an ana-frontal southwesterly flow regime will persist
   with episodes of showers and a few 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.
