What forecasters said that day

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.

NWS La Crosse, WI wrote its last area forecast discussion before this winter storm warning went out at Dec 13, 10:51 PM CST, 4 hours 27 minutes earlier.

Area forecast discussion, Dec 13, 10:51 PM CST, 4 hours 27 minutes before
Area Forecast Discussion
National Weather Service La Crosse WI
1051 PM CST Tue Dec 13 2022

.UPDATE...
Issued at 830 PM CST Tue Dec 13 2022

Main update this evening focuses on the increasing (60-70% chance)
of a band of moderate to even heavy snow forming from west of
Rochester and lifting northeastward north of Winona and then into
western Wisconsin between 08-14Z. The high resolution guidance
(RAP/HRRR) have been steadfast that the warm nose along this
corridor collapses with the arrival of a second band of
precipitation after 06Z. This band is lifting northward through
southern Iowa/northern Missouri this evening with multiple
lightning strikes noted as it crossed the IA/MO border. The HRRR
and RAP forecast profiles both show a token (10-30 J/kg) of
upright convection above the dendritic growth zone with very
impressive synoptic lift through this corridor as well.

All combined, these ingredients point to an intense, albeit
brief, period of high snowfall rates within this band where rates
of 1-2 inches per hour are possible. The main limiting factor for
accumulation will be the warm surface temperatures in the
mid-30s. Therefore, the main message with this snow band will be
reduced visibilities in heavy snow and accumulating snow on
mainly grassy surfaces, though one cannot rule out some impacts
to roads for a short period.

&&

.DISCUSSION...(This evening through Tuesday)
Issued at 237 PM CST Tue Dec 13 2022

Key Messages:

 - A complex winter storm will linger through late week, with the
   highest confidence for wintry impacts, including difficult
   travel, north of I-94 from multiple rounds of precipitation
   tonight through early Thursday. Some updates to precip
   types/amounts remain likely as this system passes.

 - Much below average temperatures are increasingly likely late
   this week into next week.

Tonight-Friday: Slow-moving, complex winter storm continues

A deep, nearly vertically stacked low pressure system continues to
spin across the central plains this afternoon. Strong, gusty winds
up to 35 to 45 mph will persist into tonight with a tightened
pressure gradient and low-level jet just off the surface.

Anomalous deep moisture transport (precipitable water exceeding
0.80") will continue to feed north ahead of the low with rain
spreading north and east late this afternoon and tonight. Some
transient mixed precip could occur south of I-94 but the primary
area of concern remains areas north of I-94 where surface temps will
likely hover near freezing for a longer period of time. Some
differences in the strength of the warm nose aloft exist among
models, impacting whether precip tonight is more liquid vs
mixed/snow. The greatest risk for freezing rain will occur overnight
into early Wednesday, with impacts highly dependent on surface
temps/dew points. The NBMv4.1 has continued to increase with 60%
probabilities of at least 1/10" of ice at Medford, WI and lower
probabilities around 20% for 1/4" inch. If the temps are slightly
warmer, the icing threat would be reduced considerably. Likewise,
if the thermal profile aloft is a bit cooler, more snow/mixed
precip would be likely. Given the marginal temps, expect icing
impacts to be most noticeable for elevated surfaces. As warmer air
gets wrapped northward on Wednesday, some drizzle may persist
behind the main precip band, with a transition to rain/snow for
north central Wisconsin.

Precip amounts have trended upwards on Wednesday night across
central/northern Wisconsin as an embedded shortwave rotates
through the broader trough and moisture continues to wrap
northward around the low. Depending on the placement of this band,
several inches of snow could occur within a deformation band,
especially across north-central Wisconsin. The HREF indicates
potential for snow rates exceeding 1"/hr in the band Wednesday
night, mainly just to the east in northeast Wisconsin. So,
potential exists for higher amounts where this band develops.

Given the prolonged nature of this event with rounds of precip
spread across multiple days, elected to convert the Winter Storm
Watch for Clark/Taylor counties into a longer duration advisory
through Thursday morning. That said, will have to monitor the
potential for heavier snow Wednesday night and impacts
tonight/early Wednesday from the mixed precip.

High latitude blocking will slow the progression of the large scale
trough keeping the region in cyclonic flow aloft with snow
showers/flurries at times into the weekend and some relatively
light accumulations possible.

This Weekend into Next Week: Much Colder

A transition to colder weather is likely heading through the weekend
and especially into next week as the slow-moving low finally moves
east. There is strong ensemble agreement for much below average
temps into next week with highs in the single digits/teens by early
to middle portions of next week and potential for subzero low temps.

&&

.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
Issued at 1050 PM CST Tue Dec 13 2022

IFR to LIFR ceilings currently along and west of the Mississippi
River valley spread northeast over the rest of the region and
persist through the remainder of the TAF period. Periodic rain
occurs overnight and will result in IFR visibility reductions. A
wintry mix is expected north of BCK overnight while a brief (1-2
hour) period of moderate to heavy snow may affect areas north of
an AUM to BCK line between 08Z-14Z. The widespread rain/wintry mix
tapers off towards midday before redeveloping in the evening
after 00Z. Southeasterly winds decrease overnight to 5-15 kts by
midday.
