URGENT - WINTER WEATHER MESSAGE
National Weather Service La Crosse WI
411 AM CST Wed Feb 12 2020

...Blowing Snow, Followed By Very Cold Wind Chills...

.Light snow is expected across the area today. Strong northwest 
winds will develop behind an arctic front this afternoon, leading
to areas of blowing and drifting snow across open, unsheltered 
areas of southeast Minnesota and northeast Iowa. Hazardous
conditions may develop due to reduced visibility. Much colder 
temperatures filter in tonight through Friday, which will result 
in wind chills ranging from -20 to -35 degrees. Any residual 
moisture left on roadways may freeze and create icy conditions as 
well.

...Light snow and Blowing Snow Heading In This Afternoon, 
Followed By Very Cold Wind Chills...

.An incoming Arctic cold front will move in this afternoon
bringing with it light snow and increasingly strong and gusty  
northwest winds. These winds will produce areas of blowing and 
drifting snow across open, unsheltered areas of southeast 
Minnesota and northeast Iowa. Hazardous conditions will likely 
develop due to reduced visibility and slippery roadways. Much 
colder temperatures then filter in tonight through Friday, which 
will result in wind chills ranging from -20 to -35 degrees. Any 
residual moisture left on roadways may freeze and create icy 
conditions as well.

Cold Wind Chills Into Friday...

.An arctic front will sweep across the area tonight, bringing
around an inch of snow, strong northwest winds, and rapidly

What forecasters said that day

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

NWS La Crosse, WI wrote its last area forecast discussion before this wind chill advisory went out at Feb 11, 11:02 PM CST, 5 hours 9 minutes earlier.

Area forecast discussion, Feb 11, 11:02 PM CST, 5 hours 9 minutes before
Area Forecast Discussion
National Weather Service La Crosse WI
1102 PM CST Tue Feb 11 2020

.SHORT TERM...(Tonight through Thursday)
Issued at 152 PM CST Tue Feb 11 2020

Surface ridge and increasing subsidence aloft was rapidly scouring
out the western edge of stratocu over western Wisconsin early this
afternoon. Will see mostly clear skies across much of the forecast
area heading into this evening, though clouds may linger over
portions of north-central Wisconsin. West-southwest winds will
diminish slightly this evening, which will promote efficient
radiational cooling where skies are clear. Warm air advection aloft
will ramp up later tonight as a low level jet develops over the
region. Lows will generally be in the teens.

Focus then turns  to an incoming Arctic front and interaction with
southern stream low pressure Wednesday/Wednesday night. This front
looks to have some fairly vigorous snow showers tied to it with the
likelihood for 1/2 to 2 inches of fluffy accumulation from mainly
late afternoon into Wednesday night. Intensification of that
southern stream storm with influx of Arctic air will produce a
strong pressure gradient for gusty northwest winds in addition to
the plummeting temperatures by later Wednesday night. Will likely
see multiple hazards with this scenario: 1. Snow showers with
accumulation and reduced visibilities. 2. Increasing winds gusting
in the 25 to 35 mph range which could blow some of that
lighter/fluffy snow around with some significant reductions in
visibility/difficult travel conditions at times. 3. Very cold wind
chills of 15 to 30 below later Wednesday night into Thursday
morning. With this in mind, will likely need at least a Winter
Weather Advisory for a good portion of the area Wednesday afternoon
through Thursday morning. Will let the mid crew tonight assess
further and issue any needed headlines. In the meantime, will beef
up hazard potential in our Hazardous Weather Outlook, Graphics, and
other venues.

.LONG TERM...(Thursday Night through Tuesday)
Issued at 152 PM CST Tue Feb 11 2020

Arctic high pressure/bitter cold airmass builds overhead Thursday
night/early Friday morning. Plan on lows in the teens below zero
with wind chills in the teens to 30 below. Daytime high Friday will
struggle into the teens above zero despite plenty of sunshine.

Moderating temperatures take place for the weekend as mid-level
heights rebound over the central CONUS. Will have to watch for a
chance of light snow Saturday though as models show a trough of low
pressure passing through the region. A ridge of high pressure
rebuilds into the region Sunday for quiet weather. Look for highs
Saturday and Sunday in the 30s with lows Saturday night generally
in the teens.

Monday into Tuesday bears watching as both the GFS/ECMWF have a
fairly vigorous low pressure system passing through the region.
There will be the potential for mixed precipitation with this
system.

&&

.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
Issued at 1101 PM CST Tue Feb 11 2020

An arctic cold front entering into North Dakota late this evening
will drop rapidly southeast and pass through both airports by late
Wednesday afternoon. The low level jet ahead of the front will
cause low level wind shear for both sites through about mid-
morning Wednesday. Low clouds with MVFR ceilings are expected to
precede the front by a couple of hours and these should spread
over both sites by mid-afternoon. A band of light snow along and
behind the front will produce a couple hours of visibility
reductions before this ends. However, the winds will swing around
to the north/northwest behind the front and become quite gusty.
Gusts will be in the 20 to 25 knot range for all of Wednesday
evening and this will be enough to continue the visibility
reductions with blowing snow at KRST. With slightly lower wind
speeds and the wind direction not be favorable for blowing snow at
KLSE, did not include this in the forecast for now.

This Hazardous Weather Outlook is for portions of southeast
Minnesota...northeast Iowa and southwest into central Wisconsin.

.DAY ONE...Today and Tonight

No hazardous weather is expected at this time.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

An Arctic cold front is expected to produce light snow Wednesday
afternoon through Wednesday night. Snow amounts will generally
range from 1 to 2 inches, with highest amounts expected across
southwest into central Wisconsin. Gusty northwest winds of 15 to
25 mph, gusting to 35 mph behind the front are expected to
produce areas of blowing snow, mainly across the open and
windprone areas of southeast Minnesota and northeast Iowa. Travel
will likely be impacted, especially for the late afternoon and
evening commute.

Wind chill values of 10 to 30 below zero are then expected at
times from Wednesday night through Friday morning. The coldest
wind chills will be west of the Mississippi River.
