Updated at 1117 PM CDT Fri Sep 11 2026- Thunderstorm chances return Saturday with medium confidence in exact placement and coverage.
- Unseasonably hot temperatures continue this weekend through at least the middle of next week. Expect heat headlines at times.
- While much of the region has received rainfall over the past 36 hours, the ongoing drought conditions will require much more rainfall for improvement. Fire weather concerns will continue during periods of stronger winds.
