Area Forecast Discussion
National Weather Service La Crosse WI
1247 AM CDT Wed Apr 8 2026

.KEY MESSAGES...

- A brief period of a wintry mix along and north of I-94 early
  this morning. Some light icing could occur in the pre-sunrise
  hours prior to temperatures warming above freezing. Impacts
  should be minimal.

- Windy and warmer today. Winds gusting to 40-45 mph in MN/IA,
  30-40 mph elsewhere, peaking around midday. Temperatures warm
  into the 60s before rain spreads across the area from
  northwest to southeast in the afternoon and evening.

- More rain likely Thursday night (60-80% chance) for northeast
  Iowa and southwest WI with amounts generally between 1/4 to
  1/2 of an inch or less.

- Warming into the weekend. Periodic rain is expected but any
  signal for heavy rainfall is of lower confidence at this time.

.DISCUSSION...
Issued at 1245 AM CDT Wed Apr 8 2026

Wintry Mix Early this Morning Northeast of I-94

A band of rain showers has been lifting northeastward out of
Iowa towards I-90 late this evening as mid-level theta-e
advection intensifies on the backside of our departing ridge.
With near or even below freezing wet bulb values at
precipitation onset owing to our dry sub-cloud layer, there have
been several reports over Iowa of snow/sleet mixing in with the
stronger shower cores. Overall trends in the forecast remain on
track with the main threat for freezing rain being northeast of
I-94 with a light glaze expected by sunrise. Highest confidence
in icy conditions is on elevated surfaces, but some untreated
roadways could see slick spots for the morning commute. The
freezing rain quickly departs after sunrise with rapidly warming
temperatures through the morning.

Windy and Warmer Today, Rain in the Afternoon to Evening

The low-level jet cranks up with the aforementioned low-level
warm air advection with wind speeds increasing to the 50-60kt
range at 850 mb by sunrise. As daytime mixing commences around
8-10am, these winds will be quickly transported to the surface
in the form of gusts in the 40 to 45 mph west of the Mississippi
River and slightly lower gusts further east. Wind speeds
decrease as the afternoon continues, and clouds and rain showers
increase, all causing less favorable mixing conditions. Low-
level theta-E convergence increases as the front moves across
the area from west to east, thus rain chances are higher and
more widespread heading into WI. Given the progressive nature of
the front, rainfall amounts east of the Mississippi River
should be around 1/4 to 1/2 of an inch. A token degree of
instability south of I-90 could generate a rumble of thunder.

More Rain South of I-90 Thursday Night

The cold front that moves through this afternoon will stall to
the south and be worked on by another shortwave moving through
the northern stream of the split westerly flow Thursday late
afternoon and night. This excites southerly low-level
convergence flow into the front with strong moisture transport
convergence and some instability near the I-80 corridor.
Northeast Iowa and southwest WI are on the northern edge of the
rain shield late Thursday afternoon and night. Amounts should
taper off as one progresses northward towards I-90, but
locations closer to Dubuque could see rainfall values in the 1/4
to 1/2 inch range depending on small nuances in the exact
placement of the lower tropospheric front.

Warming into the Weekend, Periodic Showers into Next Week

Good consensus exists on a pattern evolution this weekend as a
longwave trough forms in the western U.S. Beginning later on
Saturday, a series of weather systems eject through the area in
southwest flow from this trough as warmth and moisture build in.
Precipitable water mean values in the 07.00Z Grand Ensemble are
around 1 inch and the 07.00Z ECMWF Ens EFI has a good footprint
for much above normal temperatures. Thus, the ingredients are
there for heavy rainfall, although right now the model spread is
dominating with lower predictability (10%) for any one location
receiving over an inch in 24 hours. With the recent above
average rainfall (300 percent of normal) over much of the area,
rivers will be running elevated, so the heavy rain potential
will need to be monitored. High temperatures look to be in the
70s Sunday and Monday, with the deterministic NBM providing
realistic guidance. The probabilistic NBM guidance bias-
corrected members are really jacking the distribution (7F warmer
on average) - so not using the probabilistic T distribution for
now. The pattern breaks by mid-week it appears.

.AVIATION /06Z TAFS THROUGH 06Z THURSDAY/...
Issued at 1245 AM CDT Wed Apr 8 2026

An area of light showers is beginning to develop over northern
Iowa which will propagate northward into the morning hours,
although with dry air below the cloud layer over northeast Iowa,
confidence isn't overly high that precipitation will be
realized at the surface west of the Mississippi River. This area
shifts northeastward through the early morning hours.
Saturation increases across Wisconsin as this area moves
northeast, resulting in higher confidence of precipitation at
the surface. A brief period of freezing rain also remains
possible (30-50%) across central Wisconsin, which may result in
slippery conditions on untreated surfaces.

Low level wind shear is possible overnight as the low level
wind field increases to 40-60kts, especially for those sites
located in valleys. Many locations are currently reporting gusts
at the surface, including the TAF sites, indicating low level
turbulence is favored over wind shear. However, if gusts cease,
low level wind shear and its associated impacts will become far
more likely.

South to southwest winds are expected throughout the day with
gusts in the 30-40KT range, highest west of the Mississippi
River. As we head into the afternoon and evening, another round
of showers and possibly a thunderstorm moves through the region
along a cold front. MVFR ceilings and visibility reductions are
expected in heavier showers.

.HYDROLOGY...
Issued at 1245 AM CDT Wed Apr 8 2026

The impactful crests on most rivers have passed and many
locations are receding. Rains throughout the week should have
little to no impacts on the current river trends. Our focus
remains on the weekend and whether any of the ingredients in
place can transpire into heavy rain and renewed rises on local
rivers. Confidence is low on any such details, but with
saturated soils and still elevated river levels, these bear
watching closely.
