   Areas affected...portions of eastern New Mexico and southwest Texas.

   Concerning...Severe potential...Watch unlikely 

   Valid 271820Z - 272015Z

   Probability of Watch Issuance...5 percent

   SUMMARY...Thunderstorm initiation across the higher terrain/dryline
   across eastern New Mexico and far southwest Texas is expected to
   continue early this afternoon. Isolated thunderstorms may pose a
   risk for hail/damaging winds as they move to the east.

   DISCUSSION...As of 1800 UTC, afternoon visible/radar imagery showed
   isolated thunderstorms developing near a diffuse dryline co-located
   with the higher terrain of the Sacramento and southern Sangre de
   Cristo Ranges of eastern New Mexico. Surface obs and SPC
   mesosnalysis indicate subtle upslope flow is supporting weak
   moisture advection with dewpoints in the upper 40s to low 50s F. As
   temperatures continue to warm through the 70s F, 500-1000 J/kg of
   MLCAPE and weak upslope flow should support the development of
   isolated stronger updrafts through the afternoon. Relatively modest
   westerly winds aloft may support some storm organization owing to
   25-35 kt of effective shear. Isolated multi-cell clusters or perhaps
   weak supercell structures may pose a risk for damaging wind
   gusts/large hail owing to steep low and mid-level lapse rates near 8
   C/km.

   As storms move east through the day, some upscale growth into
   loosely organized clusters with a risk for a few damaging wind gusts
   is possible. However, the lack of stronger forcing for ascent
   suggests the severe threat may remain more isolated. Given these
   factors, a weather watch is unlikely.
