   Day 2 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   1142 PM CST Wed Feb 07 2018

   Valid 091200Z - 101200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Thunderstorm potential will increase Friday to include much of the
   lower Mississippi Valley/Mid-South region and parts of the
   Southeast.

   ...Discussion...

   Broad cyclonic flow aloft will evolve into the day2 period as
   heights gradually fall across the western US. A southerly current of
   seasonally strong flow will extend along the Coastal Plain of TX
   into the Mid-South which should encourage moisture to return to this
   region enhancing the prospect for deep convection and possible
   thunderstorms. In response to heights lowering in the West, LLJ
   should evolve across the lower MS Valley late in the period and warm
   advection should aid UVV across much of the area delineated by 10%
   thunder line. LLJ should also develop across the Carolinas during
   the latter half of the period which will prove favorable for ascent
   in this region. Forecast soundings suggest the majority of
   convection will be elevated in nature, though near-surface based
   storms could form across portions of southern LA. Even so, forecast
   instability/shear do not appear strong enough to warrant severe
   probs at this time.
