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 Sioux Falls, SD wrote its last area forecast discussion before this river flood warning went out at Apr 16, 4:11 PM CDT, 22 minutes earlier.

Area forecast discussion, Apr 16, 4:11 PM CDT, 22 minutes before
AREA FORECAST DISCUSSION
National Weather Service Sioux Falls SD
411 PM CDT Tue Apr 16 2019

.SHORT TERM...(This Evening through Wednesday)
Issued at 410 PM CDT Tue Apr 16 2019

Primary concern the next 24 h is the thunderstorm chances.

All models agree on the overall set up later tonight. Strong warm
air and moisture advection around 1 km AGL will result in an
increasingly unstable atmosphere - especially along and east of
I-29. An weak upper wave will move north later tonight in an area
where 1 km moisture convergence will be greatest. HRRR, RAP, NAM
and GFS model soundings all show that initially there is a fairly
strong cap around 700 mb but this cap is gradually eroded after
06Z as the unstable layer and area of convergence move northward.
The model differences and largest uncertainty is where and when
convection will develop later tonight as well as how widespread
convection will be. One consistent message is that around 06Z
near KSUX there is ~1000 J/kg MUCAPE but CIN of 50-100. At KFSD
around 11Z there is similar MUCAPE but < 10 J/kg CIN. While we
cannot rule out convection at KSUX the most likely area for
development is in the vicinity of I-90 from far eastern SD into
southern Minnesota. Bulk shear is only 20-25 kts so expect
elevated multicellular convection. However, the initial updrafts
may be strong enough to support up to dime size hail late
tonight. As more updrafts develop north of I-90, the instability
will decrease and storms should produce primarily rain Wednesday
morning as they move north toward Highway 14.

Expect additional development of showers on the southern side of
the precipitation shield. This will keep rain over much of
southwestern Minnesota and portions of east central South Dakota
much of the morning and this is where we have categorical PoPs.
The region from Sioux Falls to Spencer Iowa seems to be where new
showers will be developing at least through midmorning before
shifting north. Farther south toward YKN and SUX, while showers
cannot be ruled out with continued instability, a capping
inversion is likely to result in little precipitation in the
morning.

On Wednesday afternoon, the surface low will move eastward from
the Missouri River into north central Iowa. It will remain
unstable ahead of the cold front. The southern jet streak will
move northward in the afternoon with enhanced divergence aloft in
the exit region. This is expected to result in convection
developing by early afternoon along the boundary. The GFS, ECMWF,
RAP and HRRR have pushed this front east more rapidly with the
initial cells developing near Highway 71 or even farther east. Did
extend likely PoPs along Hwy 71 during the early afternoon for
this convection with only chance PoPs around KSUX and KFSD.
Convection will be east of the area by late afternoon and the
persistent rain is expected to be north and east of the area by
evening.

West of I-29, the chances of precipitation are less. There is
less instability and weaker advection. The northern stream jet
streak is expected to move northeast into North Dakota. This
leaves little forcing for ascent in south central South Dakota and
there is likely to be little or no rain. North of I-90, around
KHON and KMDS, there will be better forcing for ascent but
instability is still very limited. So while rain is more likely -
especially in the morning - it will be fairly light.

The highest QPF, up to 0.75", is expected in southwestern
Minnesota where there is expected to be a few thunderstorms and
more persistent rainfall. Rainfall decreases going going farther
west and south into South Dakota and Iowa.

.LONG TERM...(Wednesday Night through Tuesday)
Issued at 410 PM CDT Tue Apr 16 2019

The primary concern in the long term is the low chance for rain
Thursday and then warm up for Saturday.

Any precipitation is expected to end by late evening on Wednesday.
Another jet streak and associated wave will move south out of
Canada Thursday. With cool air aloft, a few afternoon and evening
showers are possible west of I-29. These showers should quickly
dissipate after sunset.

Then a ridge will build across the area for Thursday and Friday.
Friday looks to be a near or just above normal - in the 60s to
around 70. Saturday looks to be the warmest day of the year so
far. A thermal ridge will develop just ahead of a cold front
which will move through during the afternoon and evening. With 925
mb temperature around +20C, this would mix well into the 70s. In
fact with brown vegetation and enhanced mixing near the front,
fairly deep mixing is possible with a few places approaching or
even exceeding 80 degrees.

After the cold front goes through normal April weather will
return with highs in the 50s and 60s. There will also be a small
chance for rain on Sunday.

&&

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1256 PM CDT Tue Apr 16 2019

Primary aviation concern is IFR conditions developing later
tonight and Wednesday as an upper wave approaches. All models now
showing the atmosphere becoming increasingly unstable overnight as
moisture increases above the surface. Elevated convection may
develop as early as 06Z around KSUX and is likely to develop by
10Z between KFSD and KSUX. Convection will increases in coverage
as it move northward into Wednesday morning. Expect that
additional showers will develop through the morning on the south
side of the area of rain mostly likely north of KSUX but may
impact KFSD. The rain will extend west to KHON by 12Z but the
probability of thunder is much lower and not included in the TAF.
In terms of clouds and visibility, as the moisture moves north,
cloud bases will lower to MVFR after 05Z and to IFR by 12Z.
Visibilities are likely to become MVFR by 12Z Wednesday. There
could be IFR visibility especially where rain is falling but
confidence is lower so kept the visibility between 3 and 5SM after
12Z.
