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 Mar 27, 10:52 PM CDT, 1 hour 53 minutes earlier.

Area forecast discussion, Mar 27, 10:52 PM CDT, 1 hour 53 minutes before
Area Forecast Discussion
National Weather Service La Crosse WI
1052 PM CDT Fri Mar 27 2020

.SHORT TERM...(This evening through Saturday)
Issued at 251 PM CDT Fri Mar 27 2020

At 2 PM, skies were partly to mostly cloudy across the Upper
Mississippi River Valley. Temperatures were in the 40s in Clark and
Taylor counties in north-central Wisconsin, and in the mid and upper
50s across the remainder of the region.

As the 850 mb moisture increases ahead of a shortwave trough
ejecting out of the Central Plains late this afternoon and evening,
showers will rapidly develop across the Upper Mississippi River
Valley. This will occur south of Interstate 90 between 4 PM and 8 PM
and across the remainder of the area between 8 PM and 1 AM. Rainfall
totals will be up to a quarter of an inch.

On Saturday morning, showers and even a few thunderstorms will
continue ahead of yet another shortwave trough ejecting out of the
Central Plains. There continues to be questions on how much elevated
instability will move into the region.  Most have very little, but
the HRRR and RAP have elevated CAPES in the 500 to 1500 J/kg range.
With ample shear aloft, there is a potential of elevated supercells
with hail being the primary threat.

On Saturday afternoon, the models continue to struggle on whether
the thunderstorms will be able to become surface-based or not across
northeast Iowa and southwest Wisconsin.  Both the HRRR and RAP say
that this is a possibility, but many of the other models say no.  If
we do get into the warm sector, the 0-1 km shear could be in the
excess of 40 knots and 0-1 km helicity of 300 to 400.  This would
provide the potential of supercell tornadoes between 4 PM and 7 PM.
Even if they do not become surface based, there will be the threat
of hail.

Like the past couple of days, there continues to be a marginal risk
of excessive rain. Precipitable water values will be in the 1 to
1.25 inch range south of Interstate 90.  This is 2 to 3 standard
deviations above-normal.

.LONG TERM...(Saturday night through Friday)
Issued at 251 PM CDT Fri Mar 27 2020

Deep sub-990 mb low pressure will move from north-central Iowa to
central Wisconsin Saturday night, with the earlier wave of showers
and storms moving off to the northeast in the evening. There could
be a few strong storms continuing to move across central Wisconsin
early in the evening before moving quickly northeast. We may then
get a brief break in the rain for part of Saturday night as the
dry slot moves overhead, but wrap-around showers will increase in
coverage late overnight and continue throughout Sunday. There may
even be a few snow flakes mixing in Sunday morning, but surface
temperatures in the mid to upper 30s will make accumulations
unlikely. As the low moves away Sunday morning, a tight pressure
gradient and large pressure rises (+8 to +10 mb in 6 hours) on the
back side of the low will lead to gusty west-northwest winds into
the early afternoon. Soundings suggest speeds at the top of the
mixed layer of 35-40 knots, and while we may not mix quite that
much downward to the surface, gusts of 30 to 40 mph will still be
possible during the day, slowly tapering off in the late afternoon
and evening as the pressure gradient relaxes. Showers should also
diminish by evening as the low moves farther away from the area.

Ridging takes over for Monday into Tuesday morning, before a
shortwave ejects eastward out of the southern plains Tuesday into
Wednesday. This system looks to stay south of our area, and thus the
bulk of the precipitation associated with this looks to stay south
as well. Deterministic models would suggest Tuesday stays dry, but
several GEFS members have light precipitation approaching from the
west and this has been carried over into the blend. Details are
murky toward the end of the week as several models show
differences in temperatures and precip. during this period. Beyond
this, there does seem to be a signal for cooler conditions
working southward at some point during the weekend.

&&

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1052 PM CDT Fri Mar 27 2020

MVFR/IFR conditions expected through the period as a potentarea
of low pressure lifts from the Central Plain into the region. Plan
on periods of rain overnight through Saturday with even some
thunderstorms in the vicinity mainly in the 20-02z time frame.
Gusty west-northwest winds will set in after midnight Saturday
night, lasting into Sunday along with scattered showers. More
detail will be given with the 12z TAF issuance.

&&

.HYDROLOGY...
Issued at 251 PM CDT Fri Mar 27 2020

Widespread 0.75" to 1" of rainfall is expected through this weekend,
much of it falling Saturday. With already elevated river levels and
fairly saturated soils from recent rainfall over the past week, this
will lead to additional rises on area rivers and possibly flooding
in some spots this weekend into early next week. In addition,
heavier rain is expected to fall to the northwest of the forecast
area which will lead to continued rises along the Mississippi River
through next week.
