   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   A few thunderstorms are possible from the Arklatex into Kentucky and
   Tennessee on Friday.

   ...Synopsis and Discussion...
   A broad upper trough will lift out of the Northeast with primarily
   zonal flow across the Plains. To the west, a broad area of
   southwesterly flow aloft will exist as northern and southern stream
   jets merge. Meanwhile, an upper high will be situated over Mexico,
   with a weakening shortwave rounding the ridge across the lower MS
   Valley. 

   At the surface, high pressure will build eastward across the Great
   Lakes in the wake of the upper trough, with a residual/dying
   boundary across the OH Valley. A large area of mid to upper 60s
   dewpoints will exist over much of TX, and into the lower MS Valley.
   Daytime heating will result in an unstable, but mostly capped air
   mass over this region. Lift will be meager, perhaps focused along
   the dying front over KY and TN where scattered storms are expected.
   Here, shear will be weak with only locally strong wind gusts
   possible.

   Elsewhere, isolated late afternoon storms are possible across the
   Arklatex, beneath the cool pocket aloft, but again, lift will be
   weak and there will be a capping inversion. Hail will conditionally
   be possible here.
