Area Forecast Discussion...UPDATED
National Weather Service Green Bay WI
1047 PM CST Fri Dec 23 2016

New Information added to update section

.UPDATE...
Issued at 1047 PM CST Fri Dec 23 2016

Will cancel the remainder of the advisory prior to the top of the
hour.

UPDATE
Issued at 946 PM CST Fri Dec 23 2016

Will leave the advisory intact a little longer, with the
expectation that we will be able to drop the remainder of it before
1100 pm. Given the fog and light precipitation out to the west,
adjusted to carry those across the area throughout the night.

UPDATE
Issued at 852 PM CST Fri Dec 23 2016

Snow is now winding down over all but the far east. Plan is to let
the western portion of the advisory expire as scheduled at 900 pm,
and drop Langlade at this time as well. Will leave the rest
intact for now, but should be able to trim some additional areas in
an hour or so.

Updated product suite will be out ASAP.

UPDATE
Issued at 719 PM CST Fri Dec 23 2016

Radar indicated a band of moderate to heavy snow over east-
central Wisconsin, generally east of a line from Y50 to CLI to MNM
to 3D2. Despite visibilities generally AOA 3/4SM, snowfall rates
around 1 inch per hour are likely with the band. But the band
should shift quickly east during the evening, which should keep
most totals in east-central Wisconsin in the 3 to 5 inch range.

Meanwhile back out to the west, returns on KARX radar have been
decreasing sharply for about the past hour. So anticipate snows
will decrease rather quickly in central Wisconsin between now and
800 pm. The scheduled 900 pm expiration of the western portion of
the advisory looks on track. The heavier snows will be out of the
east before the scheduled expiration of the advisory, but travel
will probably still be poor. Will re-evaluate the advisory for the
east a little later this evening.

UPDATE
Issued at 533 PM CST Fri Dec 23 2016

Snowfall reports received thus far have generally been in the 1.5
to 3 inch range. Most areas south of Highway 29 will likely end up
with 3-4 inches of snow, and a few 5 inch reports are possible.
Precipitation will likely taper off to DZ/FZDZ in the wake of the
main snow band. But given temperatures near or even a little above
freezing, and considering that the FZDZ will be falling into fresh
snow, at this point do not anticipate needing to extend the
advisory to cover the FZDZ. Will continue to monitor during the
evening.
&&

.SHORT TERM...Tonight and Saturday
Issued at 251 PM CST Fri Dec 23 2016

SHORTWAVE TROUGH MOVING ACROSS THE AREA WILL PRODUCE LIGHT TO
MODERATE SNOW THROUGH THE EVENING HOURS BEFORE TAPERING OFF TO
SNOW FLURRIES AND POSSIBLY SOME FREEZING DRIZZLE. THE BEST UPPER
SUPPORT IS ACROSS THE SOUTHERN TWO THIRDS OF THE FORECAST AREA
WHERE THE ADVISORY IS IN PLACE. THE COLDEST CLOUD TOPS ARE ALSO
OVER THAT AREA, WHICH SUPPORTS THE BEST SNOW BEING THERE. LOWS
TONIGHT WILL BE CLOSE TO TYPICAL HIGHS FOR THIS TIME OF YEAR.

A DRY AND MILD DAY EXPECTED FOR CHRISTMAS EVE. HIGHS SHOULD REACH
THE 30S, AND 40F IS NOT OUT OF THE QUESTION IF WE GET A FEW HOURS
OF SUNSHINE.

.LONG TERM...Saturday Night Through Friday
Issued at 251 PM CST Fri Dec 23 2016

Primary forecast issue will be the strong storm system to impact
the Northern Plains and Great Lakes region Sunday into Monday.

A ridge of high pressure will drift over the region Saturday
night. Progs are in good agreement with timing some light
precipitation in the leading edge of the warm advection region
reaching parts of Central wisconsin Sunday morning, then
spreading over the entire region Sunday afternoon and evening
with the best forcing. Cold start sunday morning with some warming
aloft but with questionable saturation may lead to patchy freezing
drizzle Sunday morning. As the air mass saturates and forcing
arrives later Sunday afternoon into Sunday night, models in
general produce a mix of zr/s/r changing to rain for much of the
area. Will continue to leave out more convective type pcpn for
now, but may be needed later this weekend. Portions of far
northern and far northeast Wisconsin could have a bit more of a
freezing rain/mix accumulation through Sunday night. Soundings
from various forecast models indicate various degrees of warming
aloft which would greatly impact pcpn type. Nevertheless there are
potential headlines Sunday afternoon and Sunday night.

As the deep surface low system tracks over the Northern Plains to
just north of Lake Superior late Sunday night through Monday, a
dry slot will work over the state. Precipitation will be on the
decrease from west to east but winds will be on the increase along
with falling temperatures. Highs on Monday likely will occur early
Monday. An icy mix covering from the day before on any remaining
snow cover should limit any blowing snow concerns on Monday with
the strong winds.

After a brief chance of lake effect snow showers far north, a
ridge of high pressure sliding over the area will provide a quiet
period of weather through Tuesday night. The next chance of light
snow arrives toward a model blended time period of Wednesday
night. Otherwise no major storm system next week at this time.
&&

.AVIATION...for 06Z TAF Issuance
Issued at 946 PM CST Fri Dec 23 2016

Generally poor (IFR/LIFR) flight conditions existed across the
entire area. Guidance continues to suggest breaks in the low
clouds will develop in eastern Wisconsin late tonight. Confidence
in that trend has diminished since the 00Z TAF issuance, so will
have a more pessimistic forecast in the 06Z TAF package.

.GRB WATCHES/WARNINGS/ADVISORIES...
NONE.

...HAZARDOUS TRAVEL CONDITIONS TO CONTINUE TONIGHT...

As of 940 pm, radar and airport observations indicated that snow
was rapidly diminishing over eastern Wisconsin. Less than an inch
of additional accumulation is expected in the east. Some flurries
and patchy drizzle and freezing drizzle were occurring in central
and north-central Wisconsin. The flurries and drizzle and freezing
drizzle will expand into the east in the wake of the significant
snows.

Despite the end of the snow, poor travel conditions are likely to
persist overnight. Most roads were snow covered and slippery.
Although temperatures were near freezing and are not expected to
drop off much tonight, it will take some time for highway crews to
complete the cleanup after the snowfall. Anyone traveling tonight
should be prepared for slippery roads, allow for a slower than
normal trip, and use extra caution.
