   Day 2 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   1133 PM CDT Fri Oct 27 2017

   Valid 291200Z - 301200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe storms are not expected over the continental U.S. Sunday.

   ...Mid Atlantic through New England...
   A strong shortwave - initially centered across the Ohio and
   Tennessee Valleys - will strengthen while taking on a negative tilt
   across the southern Appalachians.  A very strong (80-90 kt)
   mid-level jet will eject around the base of this trough and along
   the coast of the Carolinas throughout the day.

   At the surface, a trough initially located along an axis from
   central Pennsylvania southward to the Gulf Stream will shift
   eastward over time as a coastal low quickly organizes and moves
   northward to near southeastern New York State by the end of the
   period.  Along and ahead of this surface trough/coastal low, low-60s
   F dewpoints will aid in development of very marginal buoyancy, which
   should be limited due to poor lapse rates.  A few thunderstorms are
   possible, although any severe wind risk should be limited and shift
   quickly offshore during the early morning hours.
