   ...DISCUSSION...
   ...Monday/Day 4 to Wednesday/Day 6...
   A broad anti-cyclonic flow pattern is forecast to develop across the
   continental U.S. on Monday, as surface high pressure moves across
   the southern and eastern U.S. On Tuesday into Wednesday, a mid-level
   trough is forecast to move eastward across the western and central
   U.S. Weak low-level moisture return is expected to take place across
   the south-central U.S. ahead of the system. On Tuesday, thunderstorm
   development appears most likely across eastern parts of the southern
   and central Plains. By Wednesday, model forecasts have surface
   dewpoints reaching the 50s F in parts of the lower Mississippi
   Valley and Ark-La-Tex. Thunderstorms will be possible on Wednesday
   along this corridor. As the system moves across the south-central
   U.S. from Tuesday into Wednesday, a severe threat may develop.
   However, medium-range model forecasts suggest that instability will
   remain relatively weak, suggesting that any severe threat should be
   isolated and marginal.

   ...Thursday/Day 7 and Friday/Day 8...
   From Thursday into Friday, a mid-level trough is forecast to move
   from the mid Mississippi Valley quickly eastward to the western
   Atlantic. During the day on Thursday, thunderstorm development will
   be possible ahead of the trough in parts of the eastern U.S. The
   return of low-level moisture ahead of the system, and the resultant
   instability, is forecast to remain relatively weak. For this reason,
   any severe threat that develops on Thursday is expected to be
   marginal.
