   ...Synopsis...
   The mid-level low across the western US will move into the northern
   Rockies on D2/Saturday, with a surface low developing across the
   central Plains. With the deepening surface low, pressure gradients
   will increase across the central/southern Plains with breezy south
   to southwesterly winds. A cold front will move southward into the
   central Plains and eventually into the southern Plains by the end of
   the period.

   ...Southern Oklahoma into North-Central Texas...
   Ahead of the approaching cold front, surface pressure gradients will
   tighten across the southern Plains. Breezy south to southwesterly
   winds around 10-20 mph will overlap with relative humidity
   reductions to around 20-25 percent across portions of southern
   Oklahoma into north-central Texas. Temperatures will again approach
   100 F. Within this region, ERCs are in the 90-95th percentile for
   dryness. The breezy, dry, and hot conditions amid dry fuels supports
   maintaining an Elevated delineation across the region for
   D2/Saturday.

   Day 3-8 Fire Weather Outlook

   0450 PM CDT Fri Sep 18 2026

   Valid 201200Z - 261200Z

   ...Discussion...
   Weak upper troughing will enter the western CONUS on Day 3/Sunday as
   a secondary decaying upper-level trough pushes into the central
   Plains, bringing precipitation to the Northern Rockies and northern
   Plains. Meanwhile, a southward progressing cold front and related
   precipitation will bring some temporary relief to the southern
   Plains through early next week. Residing high pressure over the
   Southeast is expected to maintain hot and mostly dry conditions
   across the lower Mississippi Valley through the middle of next week,
   but prevailing light winds should suppress overall fire weather
   concerns. Ensemble guidance is in general agreement for ridging to
   build across the central-western CONUS late in the workweek as an
   upper trough evolves in the eastern Pacific, indicating stronger
   southwest winds could return to the Pacific Northwest and northern
   Great Basin. However, an expected marginal fuelscape should limit a
   broader fire weather threat.
