.DISCUSSION...
Issued at 229 AM CST Fri Feb 6 2026

Snow will continue across the area this morning,. focused mainly
along the leading edge of the cold air advection. Lift from the
LFQ of an upper jet has helped make for some higher rates despite
the fast movement of the snow showers, with visibility dropping to
around a mile at times for much of the area. Would expect the
overall accumulations to be between half an inch to an inch for
most, with areas in east-central Wisconsin likely getting towards
the higher end closer to an inch. This will likely make for some
slick spots again for the morning commute, but the highest
snowfall rates are expected to move off by the mid morning hours,
which should help reduce the impacts. Still, some light flurries
and snow will likely stick around behind the higher amounts, only
ending as we get closer to noon. This later period will be one to
watch as some light mixed precipitation could mix in at times as
ice crystals aloft become scarce due to drier air pushing in.

Quiet conditions are then expected for the rest of the Friday into
Saturday morning as colder air arrives. Expect low temperatures
to drop below zero for portions of central and north-central
Wisconsin while lingering only a few above in east-central, which
will make for a cold start to the day on Saturday. High
temperatures will be in the teens during the day. The cold will
not be around for too long however as warm air advection returns
to the region aloft during the afternoon and evening. Coupled with
a shortwave aloft, would expect another round of light snow to
move over the region late Saturday into Sunday, very similar to
yesterday and this morning. Snow totals will again be on the
lighter side, sitting around an inch or less for most
(probabilistic guidance paints out 20-30% chance of exceeding an
inch at any one location).

Warmer air then continues into next week, which will bring some
above normal temperatures into the region. High temperatures will
get into the 30s for most of the region and a few of the warmest
spots may even get to around 40. Another shot for some light
precipitation will be possible around the middle of next week but
the details such as p-type remain uncertain at this time.

Issued at 1132 AM CST Fri Feb 6 2026

Other than a few flurries across far north-central Wisconsin, snow
and visibility restrictions have ended across the region. Clouds
were beginning to scatter out, with a mix of MVFR/VFR stratus
across locations that have not scattered out yet. Clouds are
expected to scatter out this afternoon, with VFR conditions and
mostly clear skies expected by late this afternoon and lasting
through Saturday morning.

Gusty north-northwest winds of 20-30 knots are expected this
afternoon, which should ease below 10 knots later this evening.
Light winds are then expected overnight into Saturday morning.
