   ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM FAR
   EASTERN NEW MEXICO INTO WESTERN TEXAS...

   ...SUMMARY...
   Primarily damaging hail and wind are expected over the southern High
   Plains through late evening. A brief tornado or two may occur along
   the eastern New Mexico/West Texas border.

   ...Far eastern NM into west TX...
   A north-south axis of around 2000 J/kg MLCAPE currently exists over
   much of western TX, beneath modest west/northwest flow aloft and
   near the upper ridge. Visible imagery shows an expansive CU field
   over the region, and GPS PW values remain around 1.00" in an
   uncapped air mass. 

   Numerous storms currently exist over northeast NM and into the far
   western TX Panhandle, exhibiting mainly multicellular tendencies
   with one supercell complex evident southeast of TCC. Still, ample
   instability and a mean storm motion to the southeast may allow for a
   few transient supercells, with hail over 2.00" diameter. The 00Z AMA
   sounding shows steep midlevel lapse rates, but a straight hodograph
   due to weak winds below 700 mb. The large storm complex over Quay
   county appears to have the greatest chance of a tornado as it
   evolves south/southeast toward the TX state line. Otherwise, strong
   outflow production should eventually result in scattered damaging
   winds, along with a persistent hail risk as storms move through the
   South Plains later this evening. Severe potential will favor the
   instability plume, with inflow aided by increasing 850 mb winds out
   of the southeast tonight.

   ...Eastern MT...
   Scattered storms persist near a north-south oriented surface trough
   over eastern MT. The 00Z GGW sounding shows ample instability with
   MLCAPE over 1500 J/kg, and winds veering with height. Deep-layer
   shear is only 25-30 kt, but cool temperatures aloft combined with
   favorable moist southeast low-level winds may support a hail threat
   for a few more hours.
