In the mid levels, a trough will amplify over the Western States,
and will be accompanied by a belt of strong flow spreading across
parts of the Southwest to the central and southern Plains. As the
leading edge of this stronger flow and associated large-scale ascent
emerge over parts of the central and southern Rockies, a lee surface
trough will deepen across parts of the adjacent High Plains.

central/southern High Plains...
Enhanced downslope winds extending off portions of the central and
southern Rockies will support warming/drying over the adjacent High
Plains. Westerly to west-southwesterly winds of 15-25 mph with
higher gusts are forecast to combine with RH of 10-20 percent in
support of elevated to critical fire-weather conditions.
The latest model guidance suggests that overlap of critically strong
winds (speeds of 20-25 mph) and low RH (10-15 percent) will be most
likely across portions of eastern CO, northeast NM, and the western
TX and OK Panhandles.
Surrounding the Critical area, elevated to borderline-critical
