Oklahoma summary from the National Drought Summary for November 10, 2026 / South.

Exceptional drought conditions continue to worsen across Southeastern Oklahoma as part of a severe regional dry spell affecting neighboring areas like Eastern Texas and Arkansas. According to the National Centers for Environmental Information, the moisture deficit in this region is so profound that it will take 20 to 30 inches of rainfall over a three-month period to fully end the exceptional drought. While substantial recent rains have brought significant drought relief further south in Texas and east into Tennessee, Southeastern Oklahoma remains locked in a worsening, long-term precipitation deficit.
