.UPDATE...
Issued at 1239 AM CDT Sun Jun 7 2026

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

UPDATE Issued at 1100 PM CDT Sat Jun 6 2026

Update to get rid of wind advisory, as winds have diminished.

UPDATE Issued at 621 PM CDT Sat Jun 6 2026

The ongoing forecast remains in good shape. We'll be monitoring
the winds over Corson/Dewey Counties this evening to see if the
ongoing Wind Advisory will be allowed to expire early. Currently
though, the Grand River RAWS is still gusting to 46 mph.

.DISCUSSION...
Issued at 130 PM CDT Sat Jun 6 2026

High pressure across the Great Lakes and sfc low pressure over the
Rockies is tightening the pressure gradient across South Dakota
today to about 16 mb by 21z. South to southeast winds will increase
accordingly by late afternoon especially across north central SD
where winds may gust to 50 mph. The mitigating factor will be the
lack of any cold air advection, but the 40 to 50 kt llj this evening
should compensate.

The story is much the same for Sunday, though only with a 12 mb
gradient as the low moves into western SD. As it pushes east, shear
will increase along with moisture convergence. The increased
instability migrates east with the low Sunday night into early
Monday morning with a marginal to enhanced (level 3 of 5) risk for
severe storms. The slight risk extends northwest of a line from
Murdo to Eureka with the enhanced risk over portions of Corson and
Dewey county. The marginal risk is as far east as the Sisseton
Hills. All threats are possible, but strong winds and large hail are
most likely outside of the enhanced risk area. Would not be
surprised to see this system develop into an MCS as it propagates
farther east late Sunday night.

Temperatures will be a bit cooler behind the front/low on Monday,
but the respite will be brief as 90s surge back in for Tuesday. Will
need to watch heat indices on Tuesday for potential headlines as
"feels-like" temps could push above 100 south of Hwy 14. The main
concern Tuesday and into Wednesday focuses on another cold front
moving across the region, impacting central SD from around 21z
Tuesday. A 60 to 70 kt jet streak and shortwave energy moving
through the upper trough will help enhance instability around the
sfc front. For the moment, a slight risk is anticipated to cover the
entire cwa on Tuesday with Wednesday's slight risk primarily over
and east of the James Valley.

.AVIATION /06Z TAFS THROUGH 06Z MONDAY/...
Issued at 1239 AM CDT Sun Jun 7 2026

Terminals KABR,KATY,KPIR,KMBG

Expect to see VFR conditions prevailing at all TAF sites through
most of this forecast cycle. Breezy southeast surface winds
will persist through the early morning but not enough to
preclude mention of low level wind shear (LLWS) at
KABR/KPIR/KMBG terminals. Gusty southeast winds between 25-35
kts are expected by mid to late morning through the end of the
day at all terminals. Increasing low level moisture advecting
into east central SD toward the end of the period could lead to
high end MVFR/low end VFR CIGs. A PROB30 group was added to the
KMBG forecast for -TSRA potential late in this TAF cycle.
