   ...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).
