What happened

The episode as NWS ABR wrote it up.

A strong low pressure system would generated high winds as it wrapped up overhead. A peak wind gust of 74 mph was observed by the South Dakota Department of Transportation mesonet station 6 miles south southwest of Peever. 3 additional reports of wind gusts at or in excess of 70 mph were noted, while 30 more weather stations would record wind gusts at or in excess of 60 mph. Numerous trees would lose limbs in the city of Aberdeen, with at least 3 downed trees being reported. These strong winds also caused a building to collapse in the town of Sisseton. Over a 36 hour period, 1425 customers would report the loss of power.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Aberdeen, SD wrote its last area forecast discussion before the first event at May 15, 8:49 AM CST, 11 minutes earlier. Its key messages:

Cannot rule out severe storms over eastern South Dakota and western Minnesota today mainly between 11am and 3 pm. All severe weather hazards will be possible.
Showers and thunderstorms persist Thursday night through Friday night with a 50% chance or greater of seeing at least an additional half inch or more of rainfall.
The probability of low temperatures falling to 36F degrees or colder Saturday night is 40 to 80% in areas along and north of the US Highway 212 corridor.

.UPDATE...
Issued at 939 AM CDT Thu May 15 2025

Minor tweaks to the going forecast this morning to match the
trends. A couple of items of note for the next 18 hours or so.
First, still watching for severe potential as then next areas of
storms lift north across eastern SD. Thus far, only seeing
occasional periods of small hail, but the environment does get a
little more favorable over the next few hours (through around 19Z)
as this lifts north. While there could be an isolated severe
wind/hail report, greatest concern looks to be for tornadoes, as
there is strong low level shear ahead of the secondary low lifting
north across SD. CAMs continuing to show the 0-3km CAPE values
increasing towards 150-175 J/kg out ahead of this convection and
seeing a decent number of boxes checked on the Cold Core Tornado
side of things. If we can get a little clearing out ahead of the
line, like it's been trying to do over the last hour, that could
really increase the chance of a tornado. As mentioned above, only
a narrow window for things to come together to produce some
tornadoes.

Second, latest guidance is pointing towards the possibility of
high wind warning level wind gusts late this afternoon and into
the evening over central SD. This is as the sfc low peaks in
intensity over southeast ND this evening. NBM probs are in the
50-80% range, so may need to extend the existing warning northward
to account for that trend. Will address that with the afternoon
update.

.DISCUSSION...
Issued at 430 AM CDT Thu May 15 2025

As of 9z, A deep surface low continues of move east over eastern SD.
There is an area of precipitation over central and eastern SD
following behind this low as another boundary moves in from southern
SD heading towards the north. This line is bringing some storms into
northeastern SD and will continue to move north through the morning,
though these storms appear to be loosing steam as they move into
northeastern SD.

Once this initial line of storms moves through, abundant low level
moisture will start to move into eastern SD. A bit of instability
happens over eastern SD after 14z, with models showing some surface
based CAPE around/ slightly above 500 J/kg. Another boundary then
looks to move through eastern SD around/after 14z, which will
provide a source of lift to help showers and storms to develop in
addition to the moisture and instability in the area. There is also
some shear in eastern SD, which will help with the potential
development of supercell. With there being strong mid to low level
CAA over central and eastern SD, the vertical growth of the storms
will be limited. This could lead to the development of low topped
supercells that have the ability to produce severe wind, hail, and
possibility and isolated tornado. The chances for storms decreases
this evening. However, the chance for rain continues through the day
Friday, as precipitation looks to wrap around

As the surface low moves to the east, it will strengthen, with
models showing the low dropping to around 984-982mb. With the low
being so low, a tight pressure gradient has developed around it over
central and eastern SD. This tight pressure gradient will lead to an
increase in winds aloft the could be  pushed to the surface with the
CAA moving in behind the cold front. The strongest winds look to be
west of the Missouri River Thursday, with the potential for these
winds to gust over 55 mph. Areas to the east will have only slightly
weaker winds, with some areas having the potential to gust 45 to 50
mph. Strong winds look to continue through Friday, though they don't
look to be as strong as the low and its tight pressure gradient move
east.

The active pattern continues this weekend into the first half of
next week. The low pressure system that brought us a round of
precipitation, wind and cool temperatures will be departing to our
east by early Saturday. Our region will get in on some ridging aloft
through a portion of the weekend, but it will only be brief. It will
be a chilly start to Saturday morning with temperatures in the 30s.
Residual cloud cover should be able to limit any frost potential in
our area, but it's something we'll have to continue to watch for
that potential. Temperatures on Sunday morning will have a better
chance of seeing values down to frosty levels, especially in our
eastern zones where some clearing could take place. The next upper
trough will work into the region by late Sunday into early next
week. This will give our area additional chances for precipitation
through the middle of next week. Temperature trends across the
forecast area will remain below normal this weekend through the
middle of next week.

.AVIATION /12Z TAFS THROUGH 12Z FRIDAY/...
Issued at 641 AM CDT Thu May 15 2025

Terminals KABR,KATY,KPIR,KMBG

An active weather pattern will continue through most of this TAF
cycle. Areas of showers and thunderstorms will affect all
terminals throughout the morning and afternoon hours with more
general rain showers this evening into the overnight. During
periods of heavier showers and storms, IFR cigs/vsbys will be
possible. Otherwise, during lighter precipitation periods, a
general MVFR/IFR cigs/vsby scenario is expected. Strong winds will
also become a factor for aviation activities. Southeast winds
gusting 20-30 kts will be possible through the morning at
KABR/KATY while west to northwest winds gusting 30-40 kts will be
possible at KPIR/KMBG. Eventually, KABR/KATY terminals will see
winds switch around to a west to southwest direction this
afternoon into tonight while strong northwest wind gusts persist
at KPIR/KMBG.
