.DISCUSSION...
Issued at 132 AM CST Thu Nov 5 2026

As of 1:30 AM CST, temperatures across the area are in the upper
30s with winds out of the north between 10 and 15 mph. Some
patchy fog will be possible this morning along and on the
Prairie Coteau of northeast SD and in north central SD along the
Missouri River, although confidence is low as winds look to
stay a little too strong. Visibilities reductions down to about
a mile are expected if fog does develop.

Not a whole lot is going on during the forecast. Temperatures today
and Friday will be the coolest of the period with highs in the 40s,
possibly reaching the low 50s west river. WAA then takes over Friday
evening through the weekend to bring highs up to about 10-15 degrees
above normal. This looks to stay in place into at least the first
half of next work week. Fog is more likely tonight into Friday
morning across central SD as winds are much weaker and skies are
clearer. Visibilities around a half mile or less will be possible.

.AVIATION /18Z TAFS THROUGH 18Z FRIDAY/...
Issued at 1131 AM CST Thu Nov 5 2026

Terminals KABR,KATY,KPIR,KMBG

MVFR/IFR stratus is over all four terminals at this time.
Timing of improvement is uncertain across central/north central
SD. Leaning optimistic that things will improve to VFR at, at
least, the KPIR and KMBG terminals between 18Z and 00Z this
evening. KABR/KATY are expected to remain in the MVFR/IFR stratus
through tonight, and probably the first half of Friday as well.
Surface high pressure over the region will recenter ever so
slightly east of its current position later tonight, allowing
for a light south to southeast wind to develop, along with
slight pressure falls. Guidance is supportive of fog development
later tonight due to light wind and radiational cooling clear
skies across central and north central South Dakota (KPIR/KMBG)
as well as along the eastern slope of the Prairie Coteau
(upslope/terrain fog). But, at this time, Prairie Coteau fog is
not expected to be all that impactful to KATY terminal
operations.
