   The Elevated fire weather area over the southern High Plains has
   been extended eastward into most of Northwest Texas, as the latest
   guidance suggests westerly/southwesterly sustained surface winds of
   15-20 mph amidst RH values near 20%. Otherwise, only minor changes
   were needed, with some contraction to the Elevated area over eastern
   New Mexico where surface temperatures of less than 50F should temper
   the large-scale fire weather threat. See previous discussion below
   for more information.

   An upper-level trough over the West will weaken on Tuesday as a
   midlevel speed max ejects downstream across the Upper Mississippi
   Valley.  At the surface, a low pressure system will lift northeast
   toward the Great Lakes with an associated cold front slowly
   advancing southeastward over the plains.

   ...Portions of Southern High Plains...
   Although the wind speeds aloft will be weakening compared to
   previous days, sufficient flow will likely yield sustained afternoon
   surface wind speeds approaching 20 mph through boundary layer mixing
   processes.  Downslope westerly flow will also support warming/drying
   at the surface, resulting in afternoon RH values below 20% despite
   relatively cool temperatures across the region (generally at or
   below 60F).  Overall, these meteorological conditions support
   elevated fire weather conditions given the dry fuels across the
