What forecasters said that day

The local office's own words before this river flood 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 river flood warning went out at Apr 5, 2:01 PM CDT, 2 hours 9 minutes earlier. Its key messages:

  • Our stretch of cold weather continues through the first half of the new week, with the coldest temperatures coming Monday night as lows crater into the teens. Temperatures rebound back to around normal for Thursday into next weekend.
  • A couple passing shots of light rain or snow showers are expected this afternoon and Monday.

Tonight - Tuesday: Colder with Light Precipitation Chances

A cold front, currently draped across Northern Minnesota is expected
to move southeast into the area later this afternoon and evening. As
it moves through, the low levels will saturate and allow for some
light showers along the boundary. A few snowflakes could mix in
across North Central Wisconsin if the profile cools enough but
otherwise this precipitation should stay in the form of rain. Totals
will be very light as this will be a shallow topped precipitation
field. Did add some thunder mentions across Northeast Iowa as a
shallow layer of elevated instability develops in this region. While
it's only a couple hundred J/kg of CAPE, it's enough that a few
rumbles of thunder can't be ruled out.

A much cooler airmass will drop in behind this cold front with
temperatures Monday below normal in the mid 30s to lower 40s. As a
weak upper level shortwave passes through the northwest flow aloft
over the Northern Great Lakes, this will just clip our North
Central Wisconsin counties. This looks like a classic northwest
flow cold air advection cloud street snow shower type of event
tomorrow afternoon as steep low level lapse rates develop at and
below the DGZ. Accumulations will be minor and impacts outside
of briefly reduced visibilities should be nil. These snow
showers should gradually shift east of the area with dry
conditions expected overnight. As skies clear and a surface high
pressure moves into the region Monday night into Tuesday, a
prime radiational cooling night should take shape with lows
dropping into the teens to low 20s. 05.00 LREF Grand Ensemble
probabilities show a 50-90% chance of low temperatures at or
below 20 degrees. There are even some low probabilities (10-20%)
of low temperatures in the single digits, though this is mainly
confined to West/North Central Wisconsin. It isn't until the
high pressure slowly drifts east through the day on Tuesday that
we start to see some return flow and warmer air coming back
into the region.

Tuesday Night - The Weekend: Multiple Rounds of Precipitation

In the upper levels, a wave is expected to dive southeast out of
British Columbia Tuesday and ride the US/Canada border into the
Upper Midwest Wednesday into Thursday. A surface low is expected to
develop just out ahead of this and trek along a similar path through
Thursday. With increasing moisture from the aforementioned return
flow and isentropic lift ahead of the approaching wave, some light
showers are expected to develop across the region Tuesday night into
Wednesday. Current soundings show this starting off as a rain/snow
mix before converting completely to rain with low level warm air
advection making its presence felt. Then the cold front that trails
the surface low to our north and east will move in later on
Wednesday and reinforce chances for precipitation with the better
focus for lift. This may also be able to tap into some elevated
instability and create some chances for thunderstorms. Overall, QPF
from the isentropic showers look to remain light at around a tenth
of an inch. Slightly better QPF is expected with the line of showers
and thunderstorms along the front thanks to more reinforced moisture
and invigorated lift.

As the surface low moves northeast back into eastern Canada, the
trailing cold front is expected to stall somewhere across the region
by late week. Current guidance suggests this will be south of our
area which has allowed for decreased PoPs late Thursday into Friday.
In fact, a majority of both GFS and EC ensemble members have trended
lower in their precip chances and QPF behind the frontal boundary
late Wednesday. It isn't until the weekend that precipitation
chances start to return en mass as the boundary lifts north and
deeper moisture is able to make it's way into the Upper Mississippi
Valley. This is because mid/upper level flow becomes more
southwesterly, allowing for a northward surge of gulf moisture.
There's still plenty of uncertainty regarding QPF as it will
depend at least partly on the boundary. NBM 05.13 probabilities
of 24 hour QPF greater than 1 inch peak between 30-40% across
the region Sunday with precipitation expected to continue into
early next week. Though the potential for significantly heavy
rainfall from this event does not appear all that high at this
time, it will need to be monitored as the forecast evolves for
any potential hydrologic concerns.

Issued at 1252 PM CDT Sun Apr 5 2026

Ongoing VFR expected to mostly hold through the evening into
today as a band of increasing precipitation chances progressing
northwest to southeast through the evening hours into tonight
brings chances for MVFR/VFR ceilings. While main impact will be
MVFR- IFR ceilings, may see some visibility reductions as line
progresses as well. MVFR-IFR ceilings expected through Monday
morning in the wake of the frontal boundary.

.HYDROLOGY...
Issued at 1252 PM CDT Sun Apr 5 2026

The dry conditions have allowed floodwater to progress
downstream and cancellation of upstream Flood Warnings along the
Kickapoo River in southwest Wisconsin. Expect similar through
the start of the week as floodwater continue downstream.

Precipitation chances tonight expected to have limited impact as
overall amounts <0.1" expected. Although, could see slight
delay in crests or increase in observed heights temporarily.

Subsequent, widespread precipitation chances Tuesday night will
be important to monitor as river levels expected to respond
through Wednesday as heavier rainfall persists through midweek.
Amount of recovery will be main forecast detail to monitor over
the next 48 hours.
