What forecasters said that day

The local office's own words before this tornado warning went out, 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 this tornado warning went out at Jun 14, 3:23 PM CDT, 52 minutes earlier.

Area forecast discussion, Jun 14, 3:23 PM CDT, 52 minutes before

Area Forecast Discussion
National Weather Service Aberdeen SD
323 PM CDT TUE JUN 14 2016

.SHORT TERM...(This Evening through Thursday Night)
Issued at 322 PM CDT TUE JUN 14 2016

An area of low pressure, centered near KABR this afternoon, will
continue to pull north and east. Associated showers and
thunderstorms in the wraparound will exit late this afternoon/early
this evening. Across northeastern SD and the west central MN
counties there is the potential for severe storm development,
including non- supercell or low-topped supercell tornadic
development through 23z. 0-1km shear is best in those counties at
20 to 25 kts, and it converges with CAPE values of around
1200-1500 J/KG near Ortonville.

After the precip exits this evening, some patchy fog may develop
along and west of the Missouri River valley and across the Sisseton
Hills, including Watertown. Drier conditions are in store for
Wednesday. As the upper ridge pops back over the Plains on Wednesday
night, sfc temps will respond quickly with highs reaching into the
90s on Thursday. Some ridge riding shortwaves will be possible late
Thursday night as the ridge begins to buckle ahead of a PAC-
West/Canadian upper low and trough.

.LONG TERM...(Friday through Tuesday)
Issued at 322 PM CDT TUE JUN 14 2016

Upper level ridging will be in place over the central Plains during
the weekend. This will keep warm temperatures in place Friday
through Sunday with highs well into the 80s and low 90s. The ridge
appears to get flattened a bit Sunday night into Monday with
slightly cooler air moving in.

As for precipitation, weak ripples in the upper level flow, along
with surface boundaries moving through will allow for on and off
chances for thunderstorms through much of the period.

&&

.AVIATION...(For the 18Z TAFS through 18Z Wednesday Afternoon)
Issued at 1259 PM CDT TUE JUN 14 2016

MVFR CIGS are affecting a large portion of the area, along with
SHRAS. Will continue to see this activity through the afternoon
hours, with -TSRA/TSRA developing and possibly affecting KABR and
KATY. Look for precipitation to depart later this
evening/overnight with VFR conditions taking over. There is some
potential for fog across central SD late tonight/early Wednesday
morning. Confidence is low at this point, so will examine again at
00Z issuance and may have to insert fog mention.
