   Valid 191200Z - 201200Z

   An upper-level trough over the West will shift eastward today as a
   midlevel speed max moves through the base of the trough. This
   pattern will continue to support strong southwesterly flow aloft
   over the southern High Plains.  In response at the surface, a
   strengthening low pressure system will develop over Colorado during
   the afternoon hours.

   ...Portions of the Southern High Plains...
   An increasing surface pressure gradient coupled with downward
   vertical mixing of high momentum air from aloft will contribute to
   windy conditions today across much of the Southwest and southern
   High Plains.  While sustained afternoon wind speeds will exceed
   critical thresholds across the region (30 mph across southeastern
   Colorado/northeastern New Mexico decreasing to 20 mph farther east
   into western Oklahoma), RH values are expected to remain above
   critical thresholds (generally at or above 25%).  Nevertheless, fire
   weather conditions will be elevated given the ongoing drought,
   dry/dormant fuels, and strong winds across the region.
