What forecasters said that day

The local office's own words before this severe thunderstorm 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 severe thunderstorm warning went out at Jun 25, 3:02 AM CDT, 36 minutes earlier.

Area forecast discussion, Jun 25, 3:02 AM CDT, 36 minutes before

AREA FORECAST DISCUSSION
National Weather Service Sioux Falls SD
302 AM CDT Sat Jun 25 2022

.SHORT TERM...(Today and Tonight)
Issued at 301 AM CDT Sat Jun 25 2022

The wave that brought thunderstorms to parts of far southeast SD,
northeast NE and northwest IA will exit quickly this morning, taking
the chances for showers and storms with it. Some heavy rainfall
will be possible in northwest IA through about sunrise. Behind
this wave a cool front will bring cooler air and quickly
stabilize the air mass through the day with gusty northwest winds
and much drier air filtering in. Expect gusts of 30 to 35 mph at
times today with highs generally in upper 70s to lower 80s. Some
highs slightly higher in parts of northwest IA.

The main and fairly strong upper level wave across will deepen and
swing east this evening into tonight across southern Canada, which
will drop a secondary surge of cooler and drier air. This will keep
winds a bit elevated through the night, maybe a lull in the evening
and early overnight ahead of the surge of CAA. Early Sunday morning
may feel a bit chilly with temperatures in the mid to upper 50s and
winds gusting to around 20 mph.

.LONG TERM...(Sunday through Friday)
Issued at 301 AM CDT Sat Jun 25 2022

Sunday will be a few degrees cooler than Saturday as this
secondary surge of cooler air spreads across the area. With
abundant sunshine temperatures will still be very mild with highs
in the mid and upper 70s. Winds once again will gust to about 20
to 30 mph.

Sunday night into Monday will see surface high pressure move across
the area so leaned on cooler guidance for Monday morning lows,
generally lower to mid 50s. Mid level temperatures warm as south to
southwest winds increase on Monday, so expecting temperatures at the
surface to respond. Highs generally mid to upper 80s, a touch cooler
in southwest MN.

Monday night into Tuesday will see a wave drop southeast through
North Dakota into Minnesota. While the shear would support some
organized updrafts we may not actually see any updrafts as the
instability is very weak. So for now not planning on any activity
with this wave.

Tuesday night into Wednesday will see a quick short wave ridge move
through with another wave moving through a more westerly flow aloft.
Instability may be a little better with this wave so will have
chances for thunderstorms on Wednesday night.

Beyond this the fast westerly flow makes it difficult to really
pick up on any signals but overall looks like after a very hot day
Wednesday ahead of the wave temperatures will cool to near or below
normal with some continued chances for showers and thunderstorms.

&&

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1137 PM CDT Fri Jun 24 2022

Areas of thunderstorms will move across the forecast area through
12Z-14Z, bringing a potential for isolated stronger wind gusts,
along with MVFR-IFR ceilings and visibility. MVFR ceilings may
linger behind the storms into the mid-late morning, gradually
lifting/decreasing in coverage as northwest winds increase and
bring drier air into the region by Saturday afternoon. Northwest
wind gusts should reach 25-30kt through the afternoon, with gusts
quickly diminishing toward sunset.
