   ...Synopsis...
   Shortwave ridging aloft will break down through the day Friday and
   another strong mid-level jet will move across the Rockies. In the
   Plains, a broad and moderately deep surface trough will develop and
   shift eastward. These features will combine to promote another
   strong downslope wind regime in the immediate lee of the Rockies.

   ...Central/southern High Plains...
   Strong downslope winds will occur in the I-25 corridor again on
   Friday. Sustained winds of 20-30 mph, especially in Wyoming and
   Colorado, are expected. Wind gusts of greater than 60 mph could
   occur in the typically wind-prone gaps/foothills. Winds in New
   Mexico will generally be 15-20 mph. As with the last downslope wind
   event, RH will be uncertain during the afternoon. Higher confidence
   in 15-20% exists in New Mexico. With northward extent, RH will
   generally be higher, though pockets of 15-20% are at least possible.
   Cloud cover near the terrain is partly driving this uncertainty.
   Given the strength of winds and continued drying of fuels, elevated
   to locally critical conditions are expected.

   ...Southern Plains...
   Winds of 15-20 mph will develop by the afternoon as the surface
   trough deepens. Dry return flow should foster 15-25% RH. Enhanced
   winds within the lowest 2-3 km should also foster stronger wind
   gusts, particularly during the afternoon/peak heating.

   Day 3-8 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   0348 PM CST Wed Dec 17 2025

   Valid 191200Z - 251200Z

   Fire weather concerns are expected to persist through the remainder
   of the work week and into the weekend across the southern Plains and
   central/southern High Plains. A largely zonal upper-level flow
   regime is expected to persist through early next week before broad
   scale ridging becomes established over the south-central CONUS. This
   synoptic regime will favor lee troughing followed by frontal
   passages across the Plains with rain/snow chances for most regions,
   except for the Southwest/southern Plains where dry conditions will
   persist for the next several days. Long-range ensembles do show the
   potential for widespread precipitation late in the forecast period
   (D6/Mon to D8/Wed) for parts of the Southwest, but steady fuel
   drying is anticipated for the southern Plains/High Plains through
   next week.

   ...D3/Friday - High Plains/southern Plains...
   Dry conditions will prevail across the southern Plains early
   D3/Friday in the wake of Thursday's frontal passage. A surface high
   shifting eastward into the lower MS Valley will promote
   southwesterly winds across much of TX, OK, and KS. Coincidentally,
   an upper-disturbance moving across the northern Rockies will promote
   lee troughing along the High Plains, which will induce another
   downslope flow regime along the central Rockies and augment the
   pressure gradient over the Plains. 15-25 mph winds are anticipated
   within the dry return flow regime with RH reductions into the 15-25%
   range probable from the Permian Basin into western OK. In the lee of
   the Rockies, confidence in RH reductions is limited, but a strong
   wind signal coupled with drying fine fuels should promote at least a
   wind-driven fire weather concern. 

   ...D4/Saturday - southern High Plains...
   A cold front associated with a northern Plains/Great Lakes surface
   low will gradually push into the southern Plains through the day
   Saturday. While confidence in how far south this front will progress
   by peak heating remains uncertain, the general consensus among
   guidance is that 15-20 mph westerly pre-frontal winds will support
   adequate downslope warming/drying for areas of elevated to critical
   fire weather conditions.
