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.
