DISCUSSION

Issued at 1258 AM CDT Tue Jul 21 2026

As of 1 AM CDT, temperatures across the area are in the low 70s with winds out of the north. The HRRR smoke model is again showing some near surface smoke but the only effect should be a slight smoke smell to the air. Up aloft, there looks to be some smoke as well, lending a slight haziness to the sky. Highs today will be about 10 degrees cooler and then slowly increase through the rest of the work week.

Our next chance for precipitation looks to be concentrated over south central SD tonight into Wednesday morning. This is expected to stay showers. Another round comes through Thursday afternoon and evening. This may bring a chance of thunderstorms to areas west of the James River, although it is hard to say if any storms will become severe at this time. Heat returns Friday into the weekend. Models ran high on temperatures in areas with higher humidity during the last heat wave so we will see if similar high bias shows up for this weekend. This round looks to be less humid, so models may handle it better. Current forecast has highs in the 90s to low 100s, highest over central SD. Temperatures going into next work week look to start a cooling trend.
