   Areas of eastern Colorado southward/southeastward
   to northeastern New Mexico and western portions of the Oklahoma and
   Texas Panhandles

   Concerning...Severe Thunderstorm Watch 267...

   Valid 112322Z - 120115Z

   The severe weather threat for Severe Thunderstorm Watch 267

   SUMMARY...Isolated severe storms will continue across portions of
   the WW area over the next couple of hours.

   DISCUSSION...Latest radar loop shows isolated severe thunderstorms
   ongoing across the central/southern High Plains area, near a
   northwest-to-southeast cold front that has backdoored into the High
   Plains.  The airmass near and just to the cool side of the front
   remains amply unstable, with mixed-layer CAPE ranging from roughly
   1000 J/kg across northern portions of the watch, to around 2000 J/kg
   over western portions of the Texas Panhandle.

   The strongest storm at this time is a long-lived,
   southeastward-moving supercell now over southeastern Las Animas
   County Colorado, which produced very large hail (up to 2" diameter
   reported) earlier, and remains capable of producing similarly sized
   hail per latest radar data.  The storm will begin to affect
   northeastern parts of Union County New Mexico, and northwestern
   portions of Cimarron County Oklahoma over the next hour.

   Meanwhile, a storm northwestern Elbert County Colorado remains
   fairly well-organized, while a couple of other cells continue to
   increase near the New Mexico/Texas Panhandle border, which will
   likely produce at least marginally severe hail in the next 1 to 2
