.DISCUSSION...
Issued at 306 PM CST Sun Nov 30 2025

As of 20Z, there were some lingering light snow or flurries
across far eastern WI/Door County, along with lake effect snow in
far north- central WI. Otherwise, snow had ended. Blowing/drifting
concerns were also minimal as the snow has settled and winds have
started to decrease a bit. Additional snowfall accumulations of a
few tenths are possible late this afternoon and early evening
across mainly Vilas County.

Cold Temperatures...High pressure builds in from the west
tonight, and while the center of the high will pass south of the
area, the combination of light winds, partial clearing, and fresh
snow will allow temperatures to drop into the single digits, with
some locations in north-central WI likely getting a couple
degrees below zero. While winds Monday morning will be light, any
bit of wind will create a wind chill around 0 to 10 below.

Temperatures remain below normal through the week, with a
secondary push of cold air behind an Arctic front Wednesday night,
as lows drop in the single digits below zero for most. Wind
chills Thursday morning are forecast to range from 10 to 20 below.

Precip...There are minor snow chances throughout the forecast,
but overall impacts from each event looks low. The next chance
for snow is Monday afternoon and evening, primarily across
central and east-central WI (or south of Hwy 29), as this is the
far northern periphery of a system located much farther south. A
dusting to a couple tenths is possible.

Dry weather is expected Tuesday, followed by chances (30-60%) for
light snow on Wednesday in association with the Arctic front.
Moisture is rather limited, with forecast snow amounts around 1
inch or less.

There are chances for snow again Friday and into the weekend, but
specifics are hazy this far out. Sunday currently looks like the
best opportunity to pick up a couple inches of snow for some.

.AVIATION...for 18Z TAF Issuance
Issued at 1213 PM CST Sun Nov 30 2025

Overall, trends are improving as the system departs. Snow has
mostly come to an end, but lake effect snow will continue in
north-central through early to mid evening. Lake effect snow will
reach the KRHI TAF site at times, bringing temporary visibility
and ceiling drops to IFR or LIFR. Elsewhere, a mix of VFR and MVFR
conditions exist with SCT-BKN clouds around 3kft. Sky conditions
will improve area-wide this evening as low clouds depart and
partial clearing occurs.

Northwest winds remain gusty, with gusts to 20-30 kts expected
through late afternoon. While isolated blowing/drifting remains
possible from the winds, this has largely ended as the snow
settles. Winds will subside this evening and gradually back to the
W and SW tonight into Monday.
