Recent flash drought intensification across the Southern Plains and Lower Mississippi River Basin, driven by prolonged hot and dry conditions following the warmest June-August on record, continues to shape U.S. Drought Monitor assessments. As of the September 15 map, 1.7% of the contiguous United States falls in exceptional (D4) drought, concentrated in southern Texas (3.6% of state area), parts of Oklahoma, and pockets of the northern Great Basin including southern Idaho, northern Nevada, and northeastern Oregon. The next USDM update, scheduled for September 24 with data valid through September 22, will incorporate the latest precipitation, soil moisture, and streamflow observations. Short-term outlooks favor above-normal temperatures and below-normal rainfall across much of the central and southern U.S. through late September, sustaining or expanding D4 thresholds in affected regions while potential rains may ease conditions elsewhere.

Each USDM release covers the seven-day period ending Tuesday at 8:00 AM ET and is published the following Thursday.
Resolution is based on the first published US Drought Monitor release for the listed week. Subsequent revisions will not be considered; the first published release is final.
If the US Drought Monitor has not been published by 11:59 PM ET on the day following the scheduled publication date, this market will resolve to "No".
