The local office's own words before this winter storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Forecast discussion for routine afternoon forecast issuance

.SHORT TERM...Tonight and Monday
Issued at 243 PM CST Sun Jan 6 2019

The notable changes to the forecast include upgrading Forest,
Florence and northern sections of Marinette and Oconto Counties
to a winter storm warning. Did drop Waushara County from the
winter weather advisory.

Upper trough approaching from the west will bring mixed
precipitation to the area later tonight and Monday. Models
showing strong 850mb warm advection as 60 to 65 knot low level
jet cranks up later this evening and overnight. This strong surge
of warm air will cause problems with precipitation type forecasts
across central into east-central Wisconsin before changing over
to rain later tonight into early Monday morning. Surface
temperatures will climb above freezing and 850mb temperatures
climb to or a few degrees above 0C. This surge of warm air is
problematic with current headlines in place as numerical guidance
has much of the area south of highway 29 climbing into the middle
30s to near 40 by 12z Monday morning. Per coordination with NWS
La Crosse, will let current headlines run to their current
expiration time. Feeling is the midnight shift or the day shift
maybe able to cancel early. It appears there will be a sharp
gradient in snowfall amounts with less than an inch south of
Highway 10. 1 to 3 inches is expected from Highway 10 to south of
a Mosinee to Shawano to Marinette line. Over the far north, 3 to
6 inches of snow is expected with locally higher amounts are
possible across Forest, Florence, and northern sections of
Marinette and Oconto Counties. The heaviest snowfall rates are
expected late tonight into early Monday morning.

The snow will change over to rain from south to north on Monday
as warm air moves into the region. Highs on Monday may reach the
middle 40s across east-central Wisconsin.

.LONG TERM...Monday Night Through Sunday
Issued at 243 PM CST Sun Jan 6 2019

The main forecast concerns will be precipitation chances and
lake-effect potential from Monday night into Wednesday night.

A potent short-wave trof will brush the southern part of the
forecast area late Monday night into Tuesday morning, and may
bring an inch of snow to our southern tier of counties. After the
short-wave exits, CAA and subsidence will result in windy
conditions, with gusts to 30 to 40 mph over parts of central and
east central WI.

Cold northwest to north-northwest flow will lead to lake-effect
snow showers Tuesday night into Wednesday night. Several inches of
snow can be expected over Vilas county before the lake-effect
winds down Wednesday night.

An inverted surface trof will move through the region Friday into
Saturday, and bring a chance of snow showers. Quieter conditions
should prevail for the latter half of the weekend.

Mild tuemperature on Tuesday will give way to slightly below
normal readings for the latter half of the work week, followed by
a return to slightly above normal temperatures over the weekend.

.AVIATION...for 18Z TAF Issuance
Issued at 1112 AM CST Sun Jan 6 2019

The next system will approach from the west this afternoon. As the
system approaches, low level wind shear is expected to increase to
50 to 60 knots late this evening into Monday morning. Snow is
expected to arrive across portions of central and north-central
Wisconsin late this evening or early on Monday, then across the
region early Monday morning. The snow is expected to transition
to rain, freezing rain or sleet before changing over to rain.
It should be primarily snow across the north, with some rain
later Monday morning into Monday afternoon. VFR CIGS will drop
into the IFR category or lower later tonight and continue
through much of Monday.
