Area Forecast Discussion
National Weather Service Sioux Falls SD
1046 PM CDT Sun Oct 19 2025

.KEY MESSAGES...

- Breezy to gusty conditions will return to start the week with
  wind gusts between 35-45 mph expected through Tuesday. This
  along with drier conditions will lead to elevated fire danger.

- Outside of a few smaller rain chances on Monday (10%-20%),
  minimal rain chances are expected into the weekend.

- After a cooler midweek, highs will gradually increase into the
  upper 60s to low 70s heading into next weekend.

&&

.DISCUSSION...
Issued at 200 PM CDT Sun Oct 19 2025

CURRENTS & TONIGHT: A mild and breezy day continues! Taking a look
across the area, clearer skies and an abundance of sunshine
continues this afternoon as mid-level ridging slides overhead. This
along with a westerly component to the wind should allow
temperatures to reach the upper 50s to mid 60s for the day. From
here, expect the quieter conditions to persist into the overnight
hours as a combination of southerly surface winds and an approaching
warm front help keep temperatures above normal with lows mainly in
the mid to upper 40s tonight. Lastly, cloud cover will gradually
increase from west to east overnight as a mostly dry cold front
progresses through the area to start the day.

MONDAY-WEDNESDAY: Looking into the new work week, an active pattern
continues aloft as a trough ejects out of the Rockies and undergoes
cyclogenesis over the northern plains by Monday. As a cold front
swings through the area during the morning hours, could see a few
isolated showers developing mainly east of the James River Valley.
However, with such limited saturation according to soundings; not
expecting much more than a few hundredths of accumulation at best
mainly east of I-29. Otherwise, the main story continue to be the
stronger winds. As the previously mentioned system begins its
occlusion process, a tightening SPG and strengthening LLJ will help
northwesterly winds sharply increase throughout the day with wind
gusts in the 35-45 mph range expected across most areas. While the
strongest wind speeds will likely be focus along and west of I-29,
can't completely rule out an isolated pocket of up to 50 mph across
southcentral SD. With this in mind, some spots could briefly touch
advisory criteria at times. However, decided to hold off on any wind
headlines at this time since coverage will mostly likely be spotty
at best.

Nonetheless, with drier conditions and fuels in play; the windy
conditions will promote high to very high fire danger in the
afternoon to evening hours. With this in mind, make sure to limit
any activity that could create a spark as a fire could quickly
spread out of control if not contained. Looking into Tuesday and
Wednesday, an influx of cooler air behind the front will lead to
highs mainly in the 50s to low 60s. The cooler conditions will also
extend into the overnight hours as lows fall into the upper 20s to
30s leading to our first widespread freeze of the season. With this
in mind, make sure to dress appropriately as conditions will be on
the chillier side during those morning commutes. Looking aloft, the
newly formed upper level low (ULL) will continue to gradually rotate
eastwards over the next few days. As a little ribbon of dPVA rotate
around the low, can't rule out a few spits by Tuesday morning mainly
across southwestern MN. Otherwise, expect the windier conditions to
hang around for most of the day on Tuesday before quieter conditions
return by Wednesday.

THURSDAY ONWARDS: Heading into the extended period, quieter
conditions return as the previously mention ULL is replaced by a
building upper-level ridge. Increasing subsidence with the
ridging should keep any precipitation chances at bay through at
least Saturday. Otherwise, temperatures will continue to run on
the seasonal side as daily highs continue to sit in the upper
50s to low 60s. Lastly, could see more precipitation chances
return from late Sunday into Monday as a negatively tilted
trough ejects out of the Rockies.

.AVIATION /06Z TAFS THROUGH 06Z TUESDAY/...
Issued at 1046 PM CDT Sun Oct 19 2025

Aviation impacts through the period are twofold: 1) low-level
wind shear at all TAF airfields overnight given 40-50 kts from
1000 to 2000 ft agl and lesser southeast wind at the surface;
and 2) surface winds shifting to the west-northwest between
20.12-20.14Z in response to a passing cold front with frequent
gusts from 25 to 35 kts through the remainder of the period.

Any ceilings should remain at or above 8000 ft agl and given
dry sub-cloud layer, not expecting any rain at TAF airfields.
