What forecasters said that day

The local office's own words before this wind advisory 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 wind advisory went out at Jun 16, 12:31 PM CDT, 9 minutes earlier. Its key messages:

  • Scattered showers with isolated thunderstorms will return starting this afternoon and continue into the overnight hours. Severe weather is not expected.
  • Strong northwest winds by Wednesday will bring the return of gusts between 40-50 mph. With additional scattered showers with isolated thunderstorms possible by Wednesday afternoon, could see an additional strong wind threat.

1231 PM CDT Tue Jun 16 2026

.KEY MESSAGES...

- Scattered showers with isolated thunderstorms will return
  starting this afternoon and continue into the overnight hours.
  Severe weather is not expected.

- Strong northwest winds by Wednesday will bring the return of
  gusts between 40-50 mph. With additional scattered showers
  with isolated thunderstorms possible by Wednesday afternoon,
  could see an additional strong wind threat.

&&

.UPDATE...
Issued at 358 AM CDT Tue Jun 16 2026

Taking a look across the area, mostly clear conditions continue
tonight as temperatures continue to fall into the upper 40s to low
50s. Depending on if winds can get light enough, could get some
patchy River Valley fog to develop mainly along portions of the
James and Missouri River Valleys. While the fog won't last long,
can't rule out some brief visibility reductions on those morning
commutes. Otherwise, quieter conditions will continue into the
early afternoon with highs peaking in the low 70s to mid 80s for the
day.

Looking aloft, we're still on track for scattered showers with
isolated thunderstorms to develop this evening as an approaching
shortwave and warm front progress through the area on the nose of an
upper-level jet streak. Given the high shear/low CAPE environment,
severe weather is not expected. However, pockets of moderate
rainfall along with an occasional stroke of lightning will be
possible with any stronger activity that develops into the overnight
hours. The strongest activity will likely be focused along and north
of a Huron to Sioux Falls to Spencer line. Nonetheless, we could see
light returns across most of the county warning area (CWA) through
daybreak on Wednesday.

No significant changes to Wednesday onward; see below for details.

&&

.DISCUSSION...
Issued at 1257 PM CDT Mon Jun 15 2026

Model soundings and the latest hi-res models continue to indicate
the potential for strong wind gusts with any shower and thunderstorm
activity that develops this afternoon and evening. These wind gusts
will be tied to surface based instability of about 200-500 J/kg.
Given the diurnal nature of this activity, the best chance for the
strong wind gusts will be roughly 4 pm to 9 pm. Only very isolated
activity will linger through about 10 pm to midnight. Otherwise a
little patchy fog will be possible around the Kingsbury and
Brookings county areas late tonight and early Tuesday morning.

An unseasonably strong jet max will dive southeast Tuesday into
Wednesday. As this jet max moves into the area Tuesday, warm
advection will increase with the chances for showers and isolated
thunderstorms arriving possibly during the afternoon, but the better
chances will be at night. While forcing is fairly strong,
instability is lacking due to a fairly deep dry layer in the lower
levels. However, with the EML running around 7.5 C and some decent
forcing, showers and isolated thunderstorms will be possible with
this shot of lift. The better chances appear to be near and
northeast of a Huron to Spencer IA line with the best chances in
southwest MN.

This almost spring or fall like system will bring strong surface
winds to the area Wednesday. Gusts of 45 to 50 mph will be likely
during the day as mixing brings down some very strong winds aloft.
The latest models show a 130 knot jet around 300 mb, with
unidirectional flow from the west northwest throughout the
atmosphere. While we will have a small convective threat on
Wednesday afternoon and evening, model soundings indicate weaker
instability than today, but still some 100-300 J/kg surface based
CAPE mainly north of I-90. With the strong, unidirectional winds,
wind gusts around 50 mph with these showers will be possible.

Broad troughiness moves through Thursday and should bring quieter
weather and seasonably cool conditions.

Weak upper level ridging builds on Friday and will keep quiet weather
in place with temperatures back into the upper 70s to mid 80s.

Saturday will see a system pass by, possibly a bit to the south.
However this will be the next better chance for showers and storms
with isolated severe storms possible. Something worth keeping an eye
on.

&&

.AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/...
Issued at 1231 PM CDT Tue Jun 16 2026

VFR conditions begin the TAF period. Northwest winds with gusts up
to about 20 knots will remain for the rest of the afternoon hours.
Very light showers to sprinkles will begin to work into the area
this afternoon as well. However, confidence is not high enough to
include mention of rain in a TAF at this time. Confidence does
increase in rain chances tonight into tomorrow morning as coverage
increases in showers and an isolated storm. The low level jet (LLJ)
will strengthen and result in low level wind shear (LLWS) across
locations along and east of the James River. The LLWS and chances
for rain will diminish by tomorrow morning. Winds will be beginning
to increase out of the northwest to end the period tomorrow.
