.DISCUSSION...
Issued at 259 AM CDT Thu Sep 25 2025
Areas of dense fog have developed across north-central Wisconsin
early this morning as well as portions of central Wisconsin where
visibilities have fallen to around one quarter of a mile. With
several more hours of this fog expected will issue a Dense Fog
Advisory for these areas this morning.
Dense fog and stratus will eventually burn off a few hours after
sunrise across the region. Otherwise mostly sunny skies are
expected today as high pressure stays in control of the region. A
cold front sinking south tonight will bring the chance for some
sprinkles this evening across north-central Wisconsin, but should
otherwise track through the area fairly dry as model soundings
show a dearth of moisture.
Temperatures will fall modestly behind the cold front on Friday,
with a robust rebound this weekend as temperatures rise solidly
into the 70s with a few 80 degree readings expected across the
region. High pressure will be in control of the weather through
much of the upcoming week with dry weather and above normal
temperatures expected across the area.

.AVIATION...for 12Z TAF Issuance
Issued at 619 AM CDT Thu Sep 25 2025
An area of dense fog with VLIFR conditions has settled in across
north-central Wisconsin as well as locally at KGRB and some areas
just to the west with VFR conditions across KAUW/KCWA. This fog
should lift in the next few hours as the sun rises with only a few
daytime cumulus clouds expected the rest of the day. Clouds will
then increase late today into tonight, especially over northern
Wisconsin as a cold front brings the chance for some light
sprinkles. Models are hinting at some additional fog tonight
across north-central Wisconsin, although with MVFR or IFR
conditions instead of VLIFR expected.
