What happened

The episode as NWS ARX wrote it up.

A strong early spring storm system produced snow, sleet and freezing rain across western Wisconsin from April 10th into the 11th. Snowfall amounts generally ranged from 5 to 10 inches. Strong east winds of 25 to 35 mph with higher gusts, brought down power lines across portions of Vernon and La Crosse Counties where enough freezing rain occurred to coat exposed surfaces. The highest reported snowfall total was 10.3 inches near Montana (Buffalo County).

What forecasters said that day

The local office's own words before the first event, 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 the first event at Apr 10, 5:31 AM CST, 4 hours 29 minutes earlier.

.SHORT TERM...(Today through Thursday Night)
Issued at 355 AM CDT Wed Apr 10 2019

Strengthening/dynamic surface low pressure moving out into the
Central Plains early this morning. Lift ahead of the low, coupled
with strong/narrow mid-level frontogenetic band was generating a
band of rain/rain and snow mix across northern through east central
IA. This f-gen forcing/band of rain will slowly lift northeastward
into the area this morning with column cooling, which looks to
produce a band of snow across portions of southeast MN/northeast IA
before changing to mainly rain by afternoon. Could see 2-3 inches of
snow accumulation out that way...roughly in a line from Austin and
Dodge Center MN through Decorah IA. Away from the forcing/better
cooling of the column, mainly rain expected -spreading northeast
across the rest of the area through the day. Otherwise, a raw day on
tap with winds increasing out of the east into the 15 to 25 mph
range by afternoon and highs only in the upper 30s to lower 40s.

Still looking like some icing and accumulating snow for tonight into
Thursday morning as the low now moving into eastern NE sends more
moisture this way. Cold/gusty easterly surface winds in the 20-35
mph range, gusting to 40-45 mph will combine with falling snow and
areas of freezing rain to create a potential mess. Thinking areas
along and north of I-90 will see around an inch of snow, with 3-5
inches across Clark/Taylor counties. In addition Looks like the
potential for 1/10 to 1/4 inch of ice accumulation on mainly
elevated surfaces and some road surfaces. Not to be outdone,
elevated CAPE will produce a few embedded thunderstorms as well.
Given all the above, have issued a Winter Weather Advisory for areas
of southeast MN/southwest and central WI from 10 pm tonight through
1 pm Thursday. Look for the precipitation to be mainly rain by
afternoon as warmer air is pulled ahead of the low. Plan on high
ranging from the middle/upper 30s across northern WI, to the
middle 40s/lower 50s across portions of northeast IA into far
southwest WI.

.LONG TERM...(Friday through Tuesday)
Issued at 355 AM CDT Wed Apr 10 2019

As the low continues to churn northeast into southern MN by Thursday
evening/overnight, look for a lull in the precipitation as the dry
slot works in from the southwest.

The low continues to pull northeast toward Lake Superior Friday with
some lingering light rain or rain/snow mix hanging over the area.
Gusty southwest winds will kick in on the southern periphery of the
departing low. Otherwise, plan on highs only in the lower/mid 40s.

The weekend is looking cooler than normal with a chance of rain
moving back in Sunday into Sunday night as another storm system
tracks out of the mid-Mississippi River Valley toward the Great
Lakes region. Plan on highs in the 40s with lows in the mid 20s to
mid 30s.

A bit warmer and dry for Monday as a ridge of high pressure builds
in from the Plains. Highs look to be in the upper 40s to middle 50s.

Another chance of rain moves back in for Tuesday.

.AVIATION...(For the 12Z TAFS through 12Z Thursday morning)
Issued at 630 AM CDT Wed Apr 10 2019

So far, the precipitation has stayed south of both airports as it
has had a hard time moving north into the dry air in place over
southeast Minnesota into Wisconsin. As the lead short wave trough
continues to move east today, the forcing will become strong
enough to overcome this dry air with the precipitation expected to
move in by mid to late morning. Initially, it looks to be cold
enough for mainly snow at KRST before this mixes with and changes
over to rain during the afternoon. It should stay warm enough for
just rain to occur at KLSE. The current VFR conditions will
quickly go down to MVFR/IFR when the precipitation moves in and
the remain down through tonight as the rain is expected to
continue as well.

&&

.HYDROLOGY...
Issued at 355 AM CDT Wed Apr 10 2019

A shift to the west in this storm takes heaviest precipitation
west/northwest of the area. Still looking for 1.25 to 2 inches of
total qpf with this system through Friday morning. Amount of
precipitation upstream, and in Mississippi River headwaters, could
have higher impact though so will have to watch river trends next
week or two.
