Area Forecast Discussion...UPDATED
National Weather Service Aberdeen SD
1244 AM CDT Mon Oct 20 2025

.KEY MESSAGES...

- Strong winds and increased fire danger for Monday. Gusts
  ranging from 45 to perhaps 60 mph, mainly west of the James
  River. Headlines in effect for wind impacts on Monday.

- Much of the region forecast to drop to 32 degrees or below
  Tuesday night, with mid/upper 20s possible in and around the
  James River valley.

&&

.UPDATE...
Issued at 1240 AM CDT Mon Oct 20 2025

The aviation discussion has been updated for the 06Z TAFS.

UPDATE Issued at 810 PM CDT Sun Oct 19 2025

The ongoing forecast remains relatively unchanged. There was a few
adjustments made to the PoPs, wind, and wind gusts. None of the
adjustments will lead to changes in the wind headlines, so they will
be kept the same. Updates are out.

&&

.DISCUSSION...
Issued at 333 PM CDT Sun Oct 19 2025

Main impacts in the short term period are the strong winds and
high/very high fire danger expected on Monday. Low pressure still
looks to move east across SD overnight and into Minnesota by Monday
afternoon. Models continue to suggest western/central SD see the
strongest winds on Monday, mainly along and west of the Missouri
River. Bufkit momentum transfer winds, 90th percentile NBM winds,
and raw model guidance output continue to show advisory level winds
should be met fairly easily west of the James River. What gets a bit
more questionable is if warning level winds (58+mph gusts) can be
reached over the western CWA. Signals are a bit mixed in that
regard, so went ahead and issued a High Wind Watch over the far
western CWA. East of there, a Wind Advisory has been posted. Kept it
west of the James River for now as current guidance looks marginal
in that area. But, overnight shift will have to monitor model trends
and see if it needs to be expanded east any further.

Precipitation does not appear to be a big factor as this whole
system moves through. Some light showers look to move across north
central SD late tonight, with most of the CWA staying dry. Will be
watching for wrap-around showers as well Monday afternoon into
Monday night, but overall the rainfall amounts look to be less than
0.25in.

Tuesday still appears windy across eastern portions of the CWA as
low pressure continues to move away from the region, although wind
speeds do not appear to be strong enough to warrant headlines at
this time. Will then be watching surface high pressure moving in
Tuesday night with chilly temperatures expected. Much of the CWA
will drop to freezing or below, with upper 20s forecast in the James
valley and surrounding areas. NBM probability of low temps at 25
degrees or lower Wednesday morning is around 40-50% in the James
valley, so opted to drop Aberdeen's low just a couple degrees and
have us closer to around 26 degrees.

The rest of the forecast Wednesday through next Sunday looks mostly
dry with limited impacts. If anything, NBM is showing wind gusts in
excess of 30 mph from the south next weekend, so may have to keep an
eye on fire danger by then.

.AVIATION /06Z TAFS THROUGH 06Z MONDAY/...
Issued at 1240 AM CDT Mon Oct 20 2025

Terminals KABR,KATY,KPIR,KMBG

VFR conditions are forecast through most of the TAF valid period.
There is the potential for showers at KMBG between now and 12Z. MVFR
visibilities in showers is possible. Over the next several hours,
wind speeds off the surface will start to increase and turn, with
these stronger winds and gusts getting to the surface by morning.
The wind shift and speed change will cause some low level wind shear
through sunrise at KPIR/KATY. Winds at KPIR and KMBG will become
northwest first, gusting up to 30 to 35kts prior to sunrise and
above 45kts during the day Monday. Winds at KABR and KATY will
become northwest between 10Z and 14Z Monday morning with gusts
getting to 40kts during the afternoon.
