   ...DISCUSSION...
   Severe thunderstorm potential will be low through at least Day
   6/Tuesday. In the wake of a cold front moving offshore the Atlantic
   coast and into the Gulf, strong surface high pressure will build
   east of the Rockies and persist across parts of the South and East
   through Day 6/Tuesday. As a result, a dry and stable boundary layer
   will preclude severe thunderstorm potential. 

   By the middle of the week, and upper trough is forecast to
   overspread the western U.S. As this occurs, lee surface troughing
   will allow for increasing southerly winds over the Plains, and Gulf
   moisture will begin to return northward Days 7-8/Wed-Thu. It remains
   uncertain if the upper trough will begin to eject eastward toward
   the Plains at the end of the period. If this occurs, some severe
   potential may develop across the Plains, though predictability is
   low.
