   Day 3 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   0129 AM CST Tue Dec 12 2017

   Valid 141200Z - 151200Z

   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Thunderstorms are not expected across the contiguous states on
   Thursday and Thursday night.

   ...Synopsis...
   A longwave trough being reinforced east of the U.S. Rockies into
   Thursday and Thursday night could deepen as a portion of a shortwave
   trough, now approaching southern Alaska per water-vapor imagery,
   digs south/southeast through the Plains toward the lower MS Valley. 
   Although moistening is expected within the lower troposphere across
   the Gulf Basin to off the southern Atlantic coast ahead of a cold
   front, a stable environment over land will limit thunderstorm
   development across portions of FL.  Greater buoyancy could become
   deep enough offshore across parts of the Gulf of Mexico and off the
   coast of eastern FL for lightning production, mainly Thursday night
   to early Friday.
