Severe drought conditions appear in Oklahoma and Kansas. Moderate drought conditions expand in parts of northern Texas, and Oklahoma and Kansas.
- Dry conditions are developing (rapidly) over Kansas, Oklahoma, and the Texas panhandle.
- Very low soil moisture is impacting the winter wheat sowing.
- Drought forecast suggests that drought development is likely for most of the Southern Plains region in the coming season.
U.S. Drought Monitor Conditions
- Severe drought (D2) conditions have appeared in Oklahoma and Kansas.
- Moderate drought (D1) conditions have expanded in parts of northern Texas, Oklahoma, and Kansas.
Drought Development Over the Past Month
Higher Temperatures and Evaporative Demand
- Over the last 4 weeks, the average temperatures over western Kansas and the Oklahoma and Texas panhandles have been over 4ºF above normal for this time of year.
- This has caused increased evaporative demand, meaning any precipitation in these areas would evaporate from the landscape quickly.

4-Week Evaporative Demand Drought Index (EDDI) for September 10, 2021
- Precipitation over the last 30 days has been only about 25% of average for Oklahoma and northern Texas.
- Kansas rainfall mostly came quickly and ran off quickly with minimal benefit to surface conditions.
- The 60-day percentage of average shows precipitation less than 50% of the long-term average.

Drought and Precipitation Outlook
- Both the monthly and the seasonal drought outlook show drought conditions persisting or developing over Kansas, Oklahoma, and northern Texas.
- Odds slightly favor below-normal precipitation for the Southern Plains for the remainder of the year.
- Precipitation totals usually decline over the Fall season.
