   ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF
   THE SOUTHERN ROCKIES...

   ...SUMMARY...
   The primary focus for a few few strong/severe thunderstorms this
   evening will be across the southern Rockies.

   ...Southern Rockies...

   Early-evening satellite imagery suggests a weak disturbance may be
   embedded within northwesterly flow near the CO/NM border. This
   feature is digging south-southeast around the front side of dominant
   southwestern US ridge. Scattered strong convection has evolved over
   the higher terrain ahead of the disturbance, but this activity has
   struggled to drift too far east of the mountains. While marginally
   severe hail may be noted, the primary risk is for locally severe
   winds. 00z sounding from ABQ exhibited very steep lapse rates
   through 3km with modest northwesterly flow at mid-high levels. Some
   low-end supercell threat does exist within this regime but the
   primary storm mode should be multi-cellular.

   ...Elsewhere...

   Decaying MCS is shifting east-southeast across the lower MS Valley.
   Gusty winds may accompany the lead broken squall line for the next
   few hours, but otherwise this convection should remain mostly
   sub-severe.

   Weak short-wave trough is ejecting northeast across the southern
   Appalachians. Considerable amount of convection has evolved ahead of
   this feature. While wind fields are seemingly supportive of
   organized multi-cell clusters, generally poor lapse rates will lead
   to little more than gusty winds along the leading edge of this
   convection.

   00z sounding from ABR exhibited substantial MLCAPE (1500 J/kg) with
   steep lapse rates and modest mid-high level flow. Some organization
   is noted with convection that is propagating southeast across
   central SD. Gusty winds are the primary threat for the next several
   hours with this activity.
