.KEY MESSAGES...

- There is a Slight (2 of 5) to Marginal Risk (1 of 5) for severe
weather into the morning across the central/portions of northeastern
SD. Main hazards are 90 mph winds and large hail. Additionally, the
development of a tornado or two cannot be ruled out.

-There is a Marginal Risk (1 of 5) for severe weather this afternoon
into the evening across the far eastern edge of the forecast area.
Main hazards are large hail up to 1 inch in diameter and wind gusts
of 60 mph.

- Western U.S. wildfire smoke (aloft) will be over the region
through Tuesday; potentially longer depending on how steering flow
winds evolve this week. Some minor concentrations of near surface
smoke could happen from Monday afternoon through Monday night.

- A Heat Advisory has been issued as temperatures are expected to
warm into the 90s, with dewpoints in the 70s, across far northeast
South Dakota and west central Minnesota today. Heat index
temperatures will be up into the 100F to 107F degree range for
several hours this afternoon.

- Above normal temperatures are expected to persist for most of this
week. With highs in the upper 80s to mid 90s and dewpoints well into
the 60s, and even 70s for some locations, especially from Thursday

.DISCUSSION...
Issued at 1234 AM CDT Mon Jun 29 2026

Storms are still forecast to move into central SD early this morning
and move northeast into portions of northeastern SD. Models have
continued to show these storms becoming high wind producing storms
with 90 mph winds possible as the main hazard. At the same time,
there is still the threat for large hail. This will continue into
the morning until these storms move out or dissipate by mid-morning.

A surface low will be pushing into SD today as it moves to the
northeast. Lots of warm, moist air will be pushing into northeastern
SD and MN through the day. This will help with the development of
storms over eastern SD into MN during the afternoon and evening as a
cold front pushes into an environment with a lot of instability and
shear. The high-res models are showing some storms developing during
the late afternoon moving east and really taking off during the
evening east of the area in MN. While most of the threat is to the
east, there is still a marginal risk (level 1 of 5) for severe
storms to develop. These storms could have hail of an inch in
diameter and wind gusts up to 60mph. While the main threat for
severe storms during the afternoon is over eastern SD, there could
be some scattered showers and storms that develop over north central
SD during the afternoon from energy that has wrapped around the
surface low. These storms could have hail up to an inch and winds up
to 60 mph as well.

There will be warm temperatures today over northeastern SD, with
highs in the 90s and heat index values in the upper 90s to low 100s.
A heat advisory has been issued for areas over and east of the
Prairie Coteau due to these warm temperatures. The hot temperatures
and high humidity may cause heat related illnesses in sensitive
populations and those working outside. Additionally, with upper-
level winds from the south, wildfire smoke will continue to move in
aloft over central and northeastern SD today. This smoke will most
likely stay aloft and not get to the surface, which will cause some
smokey and hazy skies.

As the surface low sits to the north, a stationary front will be
sitting over southeastern SD into MN. This will keep some slightly
cooler temperatures in the area and precipitation from forming
during the day Tuesday. This front will likely start to develop some
storms and showers during the late evening into the overnight hours
which are forecast to slowly move north into central and
northeastern SD. This will lead to a threat for storms overnight
Tuesday into the day Wednesday. Warm air will then slowly move back
into central and northeastern SD during the later part of the work
week, which will start to warm temperatures again.

will track quickly towards the northeast and may affect KABR
around 12Z and may still pose a wind threat. Otherwise sub VFR
cigs expected at KMBG/KATY early Monday morning through the
late morning. Otherwise mainly VFR/MVFR cigs at KABR/KPIR with
drops in viz with any stronger storms.
