.DISCUSSION...
Issued at 251 PM CDT Thu Jun 18 2026

Isolated showers/thundershowers across the region this afternoon in
an air mass characterized by weak instability and limited shear.
Much of this activity should wane by early evening. Later tonight, a
disturbance will move out of MT and across the Dakotas, with
additional precipitation chances (20-50%) mainly for northern
portions of the CWA as suggested by many CAM solutions. Don`t have a
good feel for areal extent of PoPs overnight, so will need to be
watched by evening shift as activity moves into the Dakotas. This
shortwave will still be over the Northern Plains on Friday and be
responsible for additional threats for precipitation mainly for the
far eastern CWA.

Next chance for precipitation comes Saturday afternoon and night,
spreading eastward towards the James River valley by Sunday. Chances
peak to 70+ percent over central SD Saturday night into Sunday.
Overall, the severe threat looks rather low as evidenced by ML
output. There could be some decent rainfall amounts Saturday night
through Sunday evening as NBM probs for greater than 0.75in in a
24hr period ending 00Z Monday ranges from 60 to 80 percent over
central/south central SD. Probs for over an inch are even around 60
to 70 percent as well.

Looking ahead to next week, the pattern appears unsettled at times
with weak disturbances potentially affecting the region.
Temperatures look to remain near normal with highs in the 70s to
near 80 at times.

Issued at 638 PM CDT Thu Jun 18 2026

Terminals KABR,KATY,KPIR,KMBG

On the whole, VFR conditions are expected to prevail at all
terminals through this TAF cycle. Precipitation chances will
increase across portions of central/north central SD later on
this evening and then shift east through the overnight hours.
Continued to go with a PROB30 line for KABR/KATY through the
early morning hours on Friday to cover this potential. If some
of this activity sneaks into KMBG area prior to the 06Z
forecast issuance, may have to amend their forecast as needed.
MVFR vsbys will be possible if a -SHRA/-TSRA pass over any TAF
site. A gusty northwest wind up to 25 kts will develop by mid to
late morning Friday at all terminals and persist through the
afternoon.
