   ...Central/Northern High Plains...
   An elevated area has been introduced from northern Colorado to
   northeastern Wyoming and southwestern South Dakota. With
   southwesterly flow aloft still positioned over the region Wednesday,
   another bout of lee troughing will yield breezy south/southwesterly
   winds during the afternoon hours. A combination of sustained winds
   around 15-30 mph and RH values around 15-25% will overlie dry fine
   fuels to promote elevated/locally critical conditions on Wednesday.

   .PREV DISCUSSION... /ISSUED 0227 AM CDT Tue Sep 19 2017/

   ...Synopsis...
   The large-scale upper trough over the West is expected to amplify on
   Wednesday, as an embedded shortwave trough drops southeastward from
   the Pacific Northwest into portions of CA/NV. Relatively dry and
   windy conditions will persist over portions of the Southwest, while
   weaker winds are expected over the central/southern Plains as a
   strong cyclone moves away from the region. 

   ...Northeast AZ/Northwest NM into the Four Corners Region...
   Sufficient residual low-midlevel flow and dry conditions will result
   in the development of elevated to locally critical wind/RH
   conditions over portions of AZ/NM into southern UT/southwest CO.
   Fuels are generally not very dry across this region, though some
   curing of finer fuels will have occurred on D1/Tuesday. An elevated
   area has been delineated over portions of northeast AZ/northwest NM
   into the Four Corners region, where the most substantial wind/RH
   conditions appear likely to develop.
