   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
   OF THE SOUTHERN HIGH PLAINS...

   ...SUMMARY...
   Strong thunderstorms are possible Friday night across parts of
   eastern New Mexico near the Sangre de Cristo and Sacramento
   Mountains. Some may pose a risk for small to marginally severe hail,
   locally damaging wind gusts, and perhaps a tornado.

   ...Southwest into the Southern High Plains...

   An upper low will develop within the base of a western trough on
   Friday. This system will progress across the Southwest toward the
   Four Corners/southern Rockies vicinity by Saturday morning. As this
   occurs, moderate mid/upper south/southwesterly flow (40-60 kt at 500
   mb) will overspread the southern Rockies and adjacent High Plains.
   At the surface, modest boundary layer moisture will spread across
   southern AZ on southerly low-level flow ahead of an
   eastward-advancing cold front. Steepening midlevel lapse rates
   within the developing mid/upper low may provide weak elevated
   instability and isolated thunderstorms are possible. 

   Further east, southeasterly low-level flow will transport modest
   Gulf moisture northwest across western Texas into eastern New Mexico
   along a surface trough/dryline. As the upper low/trough approaches
   during the afternoon into the evening, steepening midlevel lapse
   rates and surface dewpoints in the mid 50s F will support up to 1000
   J/kg MLCAPE. Vertically veering wind profiles with around 40 kt
   effective shear magnitudes suggest isolated supercells will be
   possible with initial convection during the evening. More linear
   development may occur with time (toward 06z) as stronger large-scale
   ascent overspreads the region. Strong gusts, marginal hail and a
   tornado or two will be possible with this activity.
