DISCUSSION

Issued at 111 AM CDT Thu Aug 27 2026

As of 1 AM CDT, temperatures across the region are in the upper 50s to low 60s with relatively calm winds out of the northwest to north. High pressure is in place again today with a low off to our west. The daylight hours today will be dry, and there is a slight chance of some showers/storms after midnight. These precipitation chances increase to about 25-30% after sunrise and last through the afternoon. Chances increase again to 50-75% Friday evening mainly east of the Missouri River as the low off to our west moves into the region. There is a Marginal risk (level 1 out of 5) for severe storms east of the MO river. Hazards will be 1 inch hail and 60 mph wind gusts. This low will continue to move slowly across the area Saturday, finally exiting the region late Sunday. Precipitation chances remain during this time frame. Monday looks to be dry with some slight chances for precipitation returning Tuesday through the end of the forecast.

Temperatures continue the around average trend of the last several days with highs generally in the high 70s to 80s, perhaps reaching 90 west river Friday and Saturday. There could be a slight haze to the sky today and Friday as another round of elevated smoke makes its way across the region. Winds with that incoming low will be in the 25-35 mph range Friday afternoon mainly in central SD.
