.DISCUSSION...
Issued at 109 AM CDT Wed Sep 30 2026

As of 1 AM CDT, temperatures around the region are in the low to
mid 50s with light winds. Fog has formed across far east central
SD and is forecast to spread west into northeast SD and north
into west central MN through the rest of the early morning
hours. This is expected to dissipate through the late morning.

We have a couple chances for showers through the second half of the
week. The first is late Thursday into early Friday morning as a cold
front moves across the region. The second is Saturday as a shortwave
moves across the area. Both events have chances less than 40%.
Thursday`s precipitation will be concentrated over central SD with
accumulations of more than a tenth of an inch at around or less than
20%. Similar chances for Saturday, concentrated across northeast SD.

Highs today will be 5 to 10 degrees above average before we sink
below average Thursday through the weekend. Models are still showing
a slight warm up going into next work week. Still expecting stronger
wind gusts Friday for areas west of the Missouri River, up to 30
mph, potentially up to 35 mph in south central SD. Wind gusts will
also be in the 25-35 mph range again Monday across most of the
forecast area as high pressure gets pushed out by low pressure.
