.DISCUSSION...
Issued at 146 PM CST Tue Nov 10 2026

A period of unsettled weather will arrive Wednesday as a compact
short-wave, currently over the Northern Plains, moves across the
region. WAA ahead of the main short-wave will kick off a round of
light rain showers early Wednesday morning, mainly across northern
WI. Rainfall amounts are forecast to be around a tenth or two which
won`t do much to improve the on-going drought across northern WI.
Behind the upper-shortwave a surface cold front will sweep across
the region brining additional rain showers to much of the region at
times through mid Wednesday afternoon. Behind the front winds will
become northerly leading to a prolong period of lake effect
rain/snow showers across the typical northern WI snowbelt as well as
along the Lake Michigan shoreline, especially northern Door Co.
While most areas won`t see any accumulating snow, parts of northern
Vilas Co. do have a 50-60% chance for see more than 0.5" of snow by
Thursday night. As the low and mid levels winds weaken and begin to
back around to the west Friday these lake effect snow/rain showers
will come to an end leaving mostly dry conditions across the region
for this weekend.

Temperatures will see a return to near or slightly below normal with
the influx of cooler air, with highs in the upper 30s to 40s
Thursday and Friday before gradually trending above normal over the
weekend.

.AVIATION...for 18Z TAF Issuance
Issued at 1138 AM CST Tue Nov 10 2026

VFR conditions will continue through this evening with high clouds
beginning to stream over the region this afternoon ahead of an
incoming short-wave. Wednesday morning cigs will become BKN to OVC
as they gradually lower to around 4-6kft. Along with the lower cigs
light rain showers are expected overspread the region, beginning
over northern WI early Wednesday morning and expanding in coverage
through the morning.  Within these showers brief periods of MVFR
cigs/vsbys are possible, mainly across northern WI (RHI) late
Wednesday morning. With winds becoming northerly Wednesday afternoon
expect lake effect rain/snow showers to persist at times through at
least Thursday.
