Forecast Summary

Hot weather with little heat relief overnight persists this weekend and into next week, despite the weak front in the area Sunday and Monday. Dangerous heat index values are forecast and heat stress will impact outdoor activities.

Tulsa, Fort Smith and Fayetteville are all in the midst of a multi-day stretch featuring triple digit high temperatures with more forecast. How does the current stretch of 100's stack up all-time?

Isolated to scattered thunderstorms are expected as a weak front drops southward into eastern Oklahoma and western Arkansas Sunday afternoon into Monday. Locally strong to severe downburst winds will be the main threat with storms that develop. The rainfall is unlikely to slow recent drought trends.
