.DISCUSSION...
Issued at 1241 AM CST Tue Nov 10 2026

Early this morning, some areas in the James River Valley have
conditions that could support some localized areas of patchy fog. If
fog were to develop, it will stick around into the morning before
dissipating by mid-morning. The fog will cause lower visibilities at
times, though visibilities should stay above one mile. High surface
pressure over SD will be moving out during the afternoon, and it
will continue to help to move some warm air into SD. Temperatures
today will be 10-15 degrees above normal, with highs in the 50s to
low 60s.

A low surface pressure will be pushing through SD this
evening into the overnight hours. This low pressure will bring in
some precipitation along the northerly side of it, with a 15-25%
chance for some isolated rain showers and some sprinkles over
portions of north central and northeastern SD and west central MN
this evening into the early overnight hours. Not much rainfall is
expected from these rain showers. The ensembles forecast that there
is only a 10-25% chance for greater than 0.01 inch of rain fall over
portions of north central SD and far northeastern SD and west
central MN.

Cold air will be moving in behind the surface low Wednesday through
Friday as some high pressure moves over SD. Temperatures will cool
during that time to be around normal to slightly below normal
Thursday and Friday. High temperatures during that time will be in
the low 30s to mid 40s. The high pressure and some drier air in the
atmosphere will help precipitation to stay out. As the high pressure
moves out late Friday into the weekend, warmer than normal
temperatures start to move back in, with above normal temperatures
Sunday and Monday.

.AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/...
Issued at 1135 AM CST Tue Nov 10 2026

Terminals KABR,KATY,KPIR,KMBG

VFR conditions will largely be in place through much of the TAF
period. By Wednesday morning, there may be a few areas of MVFR
CIGs across northeast SD, possibly affecting KABR/KATY. Only
including SCT mention at this time as confidence is low on how
expansive these lower clouds may be, and if they reach a BKN/OVC
nature. Will continue to monitor. A period of low-level wind
shear (LLWS) is forecast over the KPIR region tonight and
inserted mention of this into their TAF. Marginal LLWS
conditions possible at KMBG as well, but no mention at this time
for the TAF as better LLWS conditions may set up more so over
KPIR.
