.DISCUSSION...
Issued at 1253 PM CDT Sat Jul 11 2026

The persistent, strong ridge aloft will be the dominant factor in
the region`s weather through mid week. High pressure at the surface
will be a bit more transient, or at least not centered directly over
the forecast area. For ambient weather, this means hot, breezy, and
no precip through Wednesday. The heat headlines remain unchanged
with highs and/or "feels-like" temps near or over 100 degrees
potentially through Friday, especially around the Missouri River
counties. In fact, Pierre and Mobridge are forecast to be within 3
degrees of record highs Sunday through Tuesday. The southerly
breezes will moderate the apparent temperatures during peak heating
a bit. However, gusts of 20 to 35 mph combined with the heat will
also quickly dry out grasses. Can`t rule out needing a fire weather
headline by Monday when min RH falls into the upper teens west
river. Still a little early for a watch, but will be something to
consider for future forecast shifts.

Overnight lows will not offer much recovery from the heat, either,
remaining in the 70 to 75 degree range across most of the forecast
area.
