Area Forecast Discussion
National Weather Service Sioux Falls SD
1024 PM CST Mon Feb 16 2026

.KEY MESSAGES...

- Near-record to record temperatures persist through Tuesday.
  Average highs will be +25 to +35 degrees above average.

- Additional chances for high to very high fire danger are
  expected by Tuesday and Wednesday as stronger winds return.
  Areas of greater concern are near and south of I-90 with low
  precipitation chances focused north of I-90.

- Chances of accumulating snowfall return on Thursday into
  Thursday night, with low to moderate (30-50%) chances of
  snowfall amounts of at least one inch. Uncertainty remains
  high on exact amounts due to questions on the track and
  evolution of the system, but be prepared for the potential for
  minor travel impacts.

&&

.UPDATE...
Issued at 1015 PM CST Mon Feb 16 2026

Heading into Tuesday, the focus continues to be on the fire weather
concerns and precipitation chances. Starting with the rain chances,
12-18z deterministic guidance continues to pull the better chances
to the north and east of us (besides the NAM). With this being
further confirmed by bone dry sounding profiles, decided to deviate
from the ever overzealous NBM to focus POPs more along the
approaching cold front during the afternoon and evening. With that
being said, any resulting accumulations will be light at best with
the better chances along and north of I-90. Shifting gears to our
greater concerns, the combination of breezier winds and record
setting warmth will lead to more elevated fire weather concerns
mainly along the Missouri River Valley.

However, with some lingering questions on cloud cover, precipitation
chances, and timing; there's still some uncertainty on the extent of
the fire weather threat. Depending on how these variables pan out
will determine if we'll need a fire weather headline or not. Current
thoughts are leaning towards no, given the persistent cloud cover
and limited time of collocation (3 hours) between the lowest RH
values and strongest winds speeds. However, if things trend drier
and more cloud-free; there is a chance we'll have to pivot to a
short-term Red Flag Warning. Either way, make sure to limit any
burning activities for the day as the conditions could help a fire
quickly spread out of control! Lastly, behind the previously
mentioned cold front; there could be a burst of near-advisory
level wind gusts (40-50 mph) from Tuesday night into Wednesday.
The burning question is can we tap into the strong LLJ given the
time of night and limited mixing. Either way, decided to slightly
boost winds speeds through Wednesday afternoon by blending in
some of the NBM90th.

&&

.DISCUSSION...
Issued at 231 PM CST Mon Feb 16 2026

It's been another warm and pleasant mid-February day out
there! Clouds will increase through tonight as our next storm system
approaches the area, and this will prevent any fog from developing
like we saw earlier this morning. It will also mean a warm night is
ahead, with temperatures only dropping to the mid-30s to low-40s by
daybreak tomorrow. A trough will eject out of the northern
Rockies as a surface low over the northern Plains deepens. We'll
remain on the warm side of the system, so any precipitation
that falls during the day on tomorrow will be in the form of
liquid. Guidance shows some light rain moving through the area
tomorrow morning, but ample dry air in the sub-cloud layer will
prevent most of this from reaching the ground. Still, a few
sprinkles cannot be ruled out tomorrow morning.

As we head into tomorrow afternoon and evening, the cold front
associated with this system will move through the area and
provide some lift for some showers to develop. The best chance
of this occurring will be along and east of I-29, and these
showers will move into an environment characterized by 200-500
J/kg of MUCAPE, so a few rumbles of thunder cannot be ruled
out. Some wrap-around moisture from this system may clip mainly
the Highway-14 corridor (20-40% chance) tomorrow night into
Wednesday. As temperatures cool behind the front, some of this
may fall as a few snowflakes, but impacts are not expected.
Winds will become breezy once again on Tuesday as this system
deepens over the area, but more on how these winds and how this
will affect our fire weather threat tomorrow and again on
Wednesday will be discussed in the Fire Weather Section later on
in this discussion.

Attention turns to our next storm system moving in Thursday into
Thursday night. Fairly good agreement amongst guidance that a low
pressure system will drift across the central Plains, with the EC
showing the system closing off closer to our area while other
deterministic models have this moving through our area as an open
wave and then closing off to our east over eastern Iowa. Another
piece of uncertainty will come from where the system tracks, with
the NAM keeping most of the precipitation south of the area,
while most guidance gives our area at least some precipitation.
Colder temperatures should be in place by the time this system
moves through, so any precipitation would likely fall as snow.
In terms of amounts, guidance varies with anywhere between a
dusting and a few inches of snow. With so much uncertainty on
the track and development of this system, we'll need to look at
snowfall total probabilities to give us an idea of how much snow
we may see out of this system. The EC ensemble is leading the
way with snowfall chances, which shows a broad 50-80% chance of
at least an inch of snow and a 25-55% chance of at least 4
inches. Other ensembles are lower, with a 30-50% chance of at
least an inch of snow and then dropping off to a less than 15%
chance of at least 4 inches of snow. The EC continues to remain
an outlier, and with the progressive nature of this system that
most guidance shows, would tend to lean towards these lower
probabilities at this time. However, light snow and breezy
conditions on Thursday into Thursday night could lead to some
minor travel impacts no matter how much fall, so please keep up
to date with the latest forecast.

Temperature-wise into this weekend, the NBM is showing seasonal
temperatures, though this will be ultimately affected by how
much snow falls, if any, on Thursday/Thursday night. More snow
would mean colder temperatures this weekend, with less snow
meaning seasonal or even slightly warmer temperatures.

&&

.AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/...
Issued at 1015 PM CST Mon Feb 16 2026

Mostly VFR conditions will continue this TAF period. Taking a
look across the area, high level clouds continue to stream
overnight as quieter conditions persist. More rain chances will
move through the area during the afternoon to evening on
Tuesday. As a result, each TAF site has a PROB30 group to
further narrow down the timing. Otherwise, surface winds will
increase overnight and continue during the day on Tuesday with
gusts of 25-35 mph expected. Lastly, could see some patchy LLWS
by Tuesday night mainly south of I-90.

&&

.FIRE WEATHER...
Issued at 231 PM CST Mon Feb 16 2026

Winds pick up during the day tomorrow as a storm system develops
over the northern Plains. We're looking to see gusts up to 25-35 mph
during the day on Tuesday, though the strongest wind gusts are
likely to be north of the spots where the lowest relative
humidity values (RH) will be. Speaking of RH, these values will
be lowest along the Missouri River (25-35%) and increase the
farther northeast you go across the area, with minimum RH values
of 40-70% northeast of a Mitchell to Le Mars line. The area
with the best overlap of breezy winds and near critical RH
values will be south-central South Dakota. Opted to forego fire
weather headlines at this time in these areas due to the
borderline nature of the RH/wind values reaching criteria and
the fact that clouds associated with this system may limit the
mixing potential and thus lead to weaker winds and cooler
temperatures than expected. Still, elevated fire weather
concerns are expected across the area as warmer than normal
temperatures and High to Very High GFDI values continue. Wind
direction on Tuesday will start out from the southeast, turning
more west-southwesterly heading into the evening as a cold
front moves through.

Winds will be even stronger on Wednesday, gusting mainly out of the
west up to 30-40 mph. This combined with the potential for RH values
dropping below 25% mainly south of I-90 will lead to another day of
elevated to critical fire weather concerns and perhaps a better
chance of headlines being issued. However, held off on issuing
headlines for now as there are questions about how warm
temperatures will get on Wednesday. The current forecast calls
for highs dropping to the 40s for the areas that have the
strongest winds, so this could help limit fires from sparking.
It will warmer with highs in the 60s towards the Highway-20
corridor, though winds look to be a bit weaker in those areas.
Still, trends will be monitored closely and future headlines may
be needed. Snow chances return Thursday and even colder
temperatures move in through the weekend, so this help will
limit fire weather concerns for the end of the week/weekend.

&&

.CLIMATE...
Issued at 231 PM CST Mon Feb 16 2026

The forecast through Tuesday will feature additional near-record
to record highs and near record warm low temperatures:

Record high temperatures:

February 17: KFSD: 70/1981 KSUX: 71/1981 KHON: 67/1913 KMHE:70/1913

Record warm low temperatures:

February 17: KFSD: 33/1992 KSUX: 37/1930 KHON: 35/1981
February 18: KFSD: 38/1994 KSUX: 39/1971 KHON: 35/1994

Additionally, climate perspectives indicate that the current
forecast through Wednesday the 18th would push the mean monthly
temperature departure at Sioux Falls (+16 degrees), Sioux City
(+16 degrees), and Huron (+18 degrees) as the warmest February
on record through that date by a margin of nearly a full degree.
