.DISCUSSION...
Issued at 415 AM CDT Wed Oct 8 2025

Temperatures...High pressure continues to settle into northwest
WI early this morning, resulting in calm winds for central and
northern WI and temperatures as of 4AM in the upper 20s and low
30s. A slight breeze across the east has kept temperatures above
freezing.

Frost/Freeze headlines appear to be on track, and no adjustments
were made. Current end time is 14Z (9AM), with temperatures
expected to rise above freezing by that time. Today will be the
coolest day of the week, with afternoon high temps in the 55-60
degree range--a couple degrees below normal for most spots.

Tonight, once again expecting lows in the middle 20s to middle 40s
(warmest near Lake Michigan). Locations north of Hwy 29 have the
highest chance to get below freezing, with NBM probabilities
ranging from 50-95%. However, no headlines have been issued yet
given the ongoing Frost/Freeze headlines, and the potential that
the growing season is over, and these headlines may end for the
season in any counties with a hard freeze this morning.

Temperatures gradually warm through the rest of the week, with
highs in the mid 60s to low 70s Sunday into early next week.

Precipitation...High pressure will result in dry weather through
Thursday afternoon. A compact mid-level shortwave and surface cold
front moving across the state will bring a small to medium chance
of light rain Thursday night into Friday. This is followed by
another dry period through the weekend, and then a higher chance
for multiple rounds of rain late Sunday into early next week as
more upper level dynamics and surface features come into play.

.AVIATION...for 06Z TAF Issuance
Issued at 1011 PM CDT Tue Oct 7 2025

VFR conditions are expected to prevail through the TAF period at all
terminals.

Any lingering mid-level clouds that remained during the evening have
cleared out and skies are now clear across the region. Winds have
decoupled and become calm across much of central and northern WI,
however, with a tighter gradient a few 10-15kt gusts may continue
for the next few hours across far eastern WI.

A high pressure system building in over the area Wednesday will keep
skies mostly clear and surface winds light and variable.
