- Widespread triple-digit high temperatures will continue through midweek, maintaining an elevated risk for heat-related illnesses.
- Increasingly dry soils and parched vegetation resulting from flash drought will support the threat of quick fire starts and rapid fire spreads.
- Although rain will be hard to come by, a few opportunities will exist on Monday across SE Oklahoma and SW Arkansas.
