Recent U.S. Drought Monitor data for the week ending September 29, 2026, show 36% of milk cow inventory in drought-affected areas amid 50% national coverage of moderate or worse drought. Persistent hot, dry conditions have intensified drought across Texas, Oklahoma, the Lower Midwest, Mississippi River valley, and Southeast, while improvements occurred in parts of the West, northern Plains, and Northeast dairy regions. With the national dairy herd expanded and concentrated in variable zones, traders appear focused on whether these southern and central expansions of D1–D4 conditions will push the milk-cow metric above 55% for the October 6 week or stabilize near current levels. The next U.S. Drought Monitor update and any late-September precipitation shifts will provide key resolution inputs.
