...Synopsis...
A midlevel trough and related surface cyclone will advance
east-northeastward from the central CONUS to the Great Lakes through
the period. A related cold front will move southward across the
southern Plains, with strong northerly surface winds in its wake.
However, a minimal overlap between the strongest post-frontal
surface winds and low RH will limit fire-weather concerns --
especially given recent and upcoming precipitation.
Farther east, dry/breezy return flow will develop across parts of
the Southeast in response to the evolving surface low. Around 10-15
mph sustained southeasterly surface winds and 25-35 percent RH may
yield locally elevated fire-weather conditions during the afternoon.
