   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER SOUTHERN
   NEW ENGLAND AND THE SOUTHERN HIGH PLAINS...

   ...SUMMARY...
   Isolated severe thunderstorms are possible across southern New
   England as well as portions of the southern High Plains on Monday.

   ...Southern New England...

   Moisture will remain limited in advance of a progressive shortwave
   trough and its attendant cold front Monday with near-surface
   dewpoints generally in the upper 30s to low 40s F. However, cold air
   aloft with -26 C at 500 mb and likelihood of some diabatic warming
   of the surface layer should result in MLCAPE from 300-400 J/kg.
   Shallow thunderstorms are expected to develop along and just ahead
   of the front toward mid day in association with deeper ascent
   accompanying the vorticity maximum. Vertical shear and wind profiles
   within the convective layer will be modest and supportive of
   multicells. However, a few locally strong wind gusts and small hail
   might accompany the stronger storms through mid afternoon.  

   ...Southern High Plains...

   A slow-moving shortwave trough currently approaching western AZ will
   reach the southern High Plains Monday afternoon. Preceding this
   feature, dewpoints in the upper 40s to low 50s F will advect through
   the High Plains warm sector beneath steep lapse rates. As the
   surface layer warms, a corridor of MLCAPE up to 1000 J/kg will
   likely evolve. Numerous storms are expected to develop over the
   mountains of NM through southwest TX during the afternoon and spread
   east through eastern NM and west TX.  Activity may eventually
   congeal into line segments during the evening. Wind profiles will
   remain modest with 25-35 kt effective bulk shear supportive of
   multicells. However, the thermodynamic environment will support some
   threat for a few instances of locally strong to damaging wind gusts
   and hail through early evening.
