   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHWEST TX...

   ...Synopsis...
   A deep midlevel cyclone and attendant surface cyclone are forecast
   to move across portions of the South-Central States. A deep/dry
   boundary layer west of a merged Pacific front/dryline, extending to
   the south of the surface cyclone, will linger across southwest TX.
   More substantial cold advection will occur behind a stronger cold
   front advancing southward across the southern High Plains.

   ...Portions of the Southwest States to southwest TX...
   Across the Critical area encompassing portions of southwest TX,
   downslope trajectories emanating from the higher terrain of
   northwest Mexico will support warming/drying of the boundary layer.
   Minimum RH around 8-15 percent is expected. As vertical mixing
   diurnally strengthens amid enhanced flow aloft surrounding the deep
   midlevel cyclone, westerly to west-northwesterly surface winds of
   20-25 mph are forecast to combine with the aforementioned low RH
   amid dry fuels. Winds will turn more northwesterly/northerly through
   the afternoon/evening behind the southward-moving front.

   Surrounding the Critical area, elevated fire-weather conditions are
   anticipated from portions of southeast AZ to southwest TX. Despite
   areas of strong winds across portions of southwest TX to the north
   and east of the Critical area, RH is not expected to become
   sufficiently low for Critical designation.
