   Concerning...Tornado Watch 253...254...

   Valid 262043Z - 262215Z

   The severe weather threat for Tornado Watch 253, 254 continues.

   SUMMARY...Additional storms are expected to develop to the west of
   current convection along the CO/KS border by 22z. These storms will
   shift eastward across WW 253 and WW 254 through 03z with hail,
   tornadoes and damaging winds possible.

   DISCUSSION...Cloud cover has persisted across much of the region
   today, inhibiting more organized and robust convection due to
   capping and weaker insolation than forecast. Latest hi-res guidance
   appears to have finally caught on to ongoing evolution of storms
   across eastern CO/western KS into the TX Panhandle. Stronger ascent
   is starting to overspread the region as is evident in thunderstorm
   development across western and central NM and deeper cumulus noted
   in visible satellite along and just ahead of the dryline across
   eastern NM.  Where skies have cleared across parts of eastern CO
   into eastern NM, temperatures have quickly warmed into the upper 70s
   to around 80 F. Current thinking is that additional storms will
   develop along the dryline from south east CO into eastern NM and
   shift eastward across the ongoing tornado watches. With strong
   forcing roughly parallel to the surface boundary, convection may
   struggle to remain discrete and could quickly grow upscale into
   bowing segments. While this may temper the tornado threat compared
   to more discrete modes, low level shear will remain more than
   sufficient for rotating supercells embedded within lines and/or
   mesovortex generation within surging bowing segments and overall
   tornado threat will remain.
