Tonight
A shortwave trough will move just to our west and north tonight.
Soundings remain rather dry, so not anticipating much of a
chance of rain. Low temperatures will range from the mid-50s to
lower 60s.
Tuesday through Friday
A 500 mb ridge of high pressure will keep the area dry and
unseasonably warm (10 to 15 degrees above normal). High
temperatures will primarily range from the upper 70s to mid-80s.
There might be a small chance of showers just west and
northwest of the area on Wednesday night. Other than that the
Upper Midwest looks to remain dry.
Next Weekend
The 500 mb ridge slides just far enough east that some
shortwave troughs ejecting out of the western longwave trough
may bring some rain chance to the area. In addition, there are
some indications that a surface front may meander across the
region. High temperatures will range from mid-70s to mid-80s.

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 637 PM CDT Mon Sep 29 2025
Fog overnight tonight is the primary aviation concern with some
possible along and east of an EAU-OVS line. However, limiting
factor for fog appears to be efficient mixing that occurred
during the day Monday leading to relatively large dewpoint
depressions at issuance time. Within river valleys, including
LSE, light wind layer and overnight wind direction do strongly
point to valley fog but concerns about reaching saturation are
present there as well. Have elected to cover fog potential with
a BCFG mention but will monitor dewpoint depression through the
evening and amend to IFR/LIFR fog if necessary.
