.DISCUSSION...
Issued at 330 AM CST Wed Dec 24 2025

Today through early next week:

Widespread fog is advecting inland across much of the forecast
area this morning, particularly over eastern/southern portions of
the area. Per latest obs/guidance trends, have expeanded the dense
fog advisory and elevated threat area into northeast portions of
the area.

Otherwise, highly anomalous ridging over central and southern
CONUS will maintain quiet conditions this holiday week, with much
above normal, even near record, temperatures. Highs will generally
be in the 70s and lows generally in the upper 50s, but some spots
could peak at 80 degrees by Fri/Sat. The 850 thermal ridge peaks
Saturday and this should be our best chance for 80 degrees.

By Sunday, upper shortwave/upper low and associated surface low over
the great lakes region will drag a cold front across the area,
thereby increasing rain chances for Sunday into Sunday night.
Thunderstorms are unlikely given the lack of instability, however
the pressure gradient tightens with the front, so expect some gusty
winds Sunday night into Monday morning. Will have to watch how this
evolves as a limited wind graphic may eventually be needed down
the line. The wind and lingering rain should keep much of the area
above freezing Sunday night.

Winter returns early next week as a cold polar surface high
propagates towards the region in the wake of the cold front. Long
nights of sub-freezing temperatures are expected with lows in the
low to mid 20s both Mon and Tue nights. /SAS/EC/

Low stratus and fog has already begun to develop at southern TAF sites.
Expect conditions to continue to deteriorate leading to a mixture
of IFR/LIFR conditions. Amendments may be needed across multiple
sites through the overnight period as conditions deteriorate. GLH
and GWO will see a brief drop visibility by 13Z. Northern sites
will start to see improvements by 15Z. Stratus will start to lift
after 15Z with further improvements to VFR ceilings by 18Z
