Do you feel the cost of groceries in your area is rising due to recent drought?

Extreme to exceptional drought conditions have spread across Arkansas, Louisiana, Tennessee, and central Missouri. Meanwhile, Western states including Colorado and New Mexico are experiencing significant drought improvements due to a recent wet pattern.

Why it matters

The lack of rainfall in the eastern half of the country has hampered the Mississippi River, increasing costs for barge transport. Conversely, heavy precipitation in the West has provided essential moisture to regions previously suffering from long-term dryness.

Most of Arkansas, Louisiana, Mississippi, and southwestern Tennessee faced rainfall deficits of 8 to 16 inches over the past four months. Meanwhile, southern Colorado recorded 4 to 8 inches of rain near the New Mexico border.

The players

U.S. Drought Monitor

This interagency organization produces weekly maps tracking drought severity across the nation using federal data.

National Drought Mitigation Center

Based at the University of Nebraska-Lincoln, this center provides research and data to help policymakers manage drought risk.

The details

Dryness has intensified from southern and eastern Missouri into parts of east-central Illinois and central Indiana, while deteriorating conditions were also noted in parts of Georgia, the Carolinas, southern Virginia, and Maine. Forecasters anticipate heavy rain of 1.5 to nearly 4 inches through Nov. 2 for areas including central Arizona and the Texas High Plains.

The U.S. Drought Monitor released its latest mapping of drought severity on Thursday, Oct. 29, 2026.
Heavy precipitation is expected to continue for the Rockies and Texas through Nov. 2.

Seasonal Patterns

This drought assessment follows the National Drought Mitigation Center's drought tracking protocols to categorize current water shortages. The findings represent a notable shift from historical norms as extreme dryness expands while Western regions benefit from anomalous precipitation.

Residents in affected areas should monitor local water conservation advisories and municipal supply restrictions. Travelers and agricultural businesses along the Mississippi River should prepare for potential shipping delays and increased transport costs for goods.

The takeaway

The sharp contrast between the parched Mississippi Valley and the damp Western states highlights the volatility of current climate patterns. Residents should remain aware of local water usage guidelines as the drought persists in central and southern regions.
