...Synopsis...
A midlevel low will track east-southeastward from SK toward the
Upper Great Lakes through the period, while a related belt of strong
deep-layer west-northwesterly flow overspreads a post-frontal air
mass over the northern Plains. Here, a tight pressure gradient,
coupled with boundary-layer mixing into the enhanced flow aloft,
will favor a WNW/ESE-oriented corridor of 25-35 mph sustained
west-northwesterly surface winds (with higher gusts) amid 20-30
percent RH (locally lower). Elevated highlights have been added for
this corridor, with the southern edge bounded by
overnight/early-morning precipitation, and northern edge where
higher RH is expected. While fuels are somewhat marginal across the
region (ERCs generally in the 60th-80th percentile), the
strong/gusty winds and modest RH reductions warrant these
highlights.

Ahead of the primary cold front, a swath of strong
south-southwesterly surface winds will extend from the southern
Plains into the Midwest. While higher boundary-layer moisture (and
related RH) is expected across this corridor, locally elevated
conditions are still possible where fine fuels are receptive to
fire-spread (e.g., parts of western KS).
