   Areas affected...Northeast New Mexico...Far Southeast Colorado

   Concerning...Severe potential...Watch unlikely 

   Valid 190117Z - 190345Z

   Probability of Watch Issuance...20 percent

   SUMMARY...An isolated severe threat will likely continue across
   parts of northeast New Mexico this evening, and could also affect
   far southeast Colorado. Large hail and a few marginally severe gusts
   will be possible. Weather watch issuance is not expected.

   DISCUSSION...The latest water vapor imagery shows an upper-level low
   over central Arizona with cyclonic southwesterly mid-level flow
   located over the southern Rockies. Large-scale ascent appears to be
   maximized over northeastern New Mexico where widely scattered
   thunderstorms are ongoing. The airmass across eastern New Mexico is
   weakly unstable with the RAP estimating MLCAPE in the 750 to 1000
   J/kg range. In addition, forecast soundings in northeast New Mexico
   have 0-6 km shear near 40 knots with somewhat steep lapse rates
   above 700 mb. This may be enough for a supercell with potential for
   large hail. A severe gust or two will may also occur. The severe
   threat is expected to remain very isolated this evening.
