What drought has meant in Iowa
The National Drought Mitigation Center's examples of impacts observed in Iowa at each level of drought.
D0 Abnormally dry
- Corn shows drought stress; soil is dry
D1 Moderate drought
- Grasses are brown; more grass fires occur; burn bans are issued
- Pond levels decline
- Soybeans abort pods; corn test weights are struggling
D2 Severe drought
- Dryland corn has extremely low yields; commodity shortages are noted; livestock is stressed
- Fewer mosquitoes are observed
- Fire danger is high
- Surface water levels are low; algae blooms increase; voluntary water conservation is requested
D3 Extreme drought
- Pastures are dry; producers sell cattle; crops are tested for toxins; crops have pest infestation
- Seasonal allergies are worse; farmers are stressed about high feed prices
- Trees drop leaves; acorns are underdeveloped
- Warm water leads to fish kills; streambeds are low to dry
D4 Exceptional drought
- Aquatic invertebrates in waterways increase
- Extreme measures are taken to conserve water
- Row crop yields and forage production have significant impacts

This week in the Midwest
The Drought Monitor authors' narrative for the map of Sep 15, 2026, released Sep 17, 2026.
Significant rainfall was observed over western Kentucky as well as over central-to-north Missouri, leading in removal of abnormally dry conditions. Heavy rain also fell in northwestern Iowa, northern Minnesota, and a band across central Wisconsin, with drought improvement as a result in these locations. Meanwhile, a mostly rain-free week in northern Illinois and Indiana caused introduction of an abnormally dry area. Extreme drought conditions can be found in southern Missouri, northern Wisconsin, and along the borders of Minnesota with both Wisconsin and North Dakota.
Looking ahead
Over the next five days leading up to next Tuesday, above normal rainfall is forecast in south Florida as well as a large area in southern Wisconsin and Minnesota into eastern Iowa and northern Illinois. The latter area of forecasted rainfall continues to the east through central Michigan, the southern Great Lakes, Pennsylvania, New York, and much of central and southern New England. Other locations with rainfall in the forecast this week are in the Appalachian Mountains, the western Great Plains, and the Four Corners states. Unfortunately, most of Texas, Oklahoma, Arkansas, Louisiana, Mississippi, and Alabama are forecast to receive little rainfall. Dry conditions are also forecast in California, Nevada, and Washington. Much above normal temperatures are forecast to continue this week in the central and southern U.S.
The 6- to 10-day outlook (September 22-26, 2026) favors above normal temperatures continuing over nearly all of the continental United States. Areas most likely to be above normal are again the south into the southeast, plus the far north. Hawaii is also likely to be above normal. For precipitation, the Eastern Seaboard is likely to have above normal rainfall as is the Southwest. The central U.S. into the upper Midwest is likely to have below normal rainfall. Hawaii and Alaska are both likely to have above normal rain during this period.

What this means
The five categories the Drought Monitor draws, and how the map is made.
- D0 Abnormally dry
- Going into or coming out of drought.
- D1 Moderate drought
- Some damage to crops and pastures; water shortages developing.
- D2 Severe drought
- Crop or pasture losses likely; water restrictions imposed.
- D3 Extreme drought
- Major crop and pasture losses; widespread water shortages.
- D4 Exceptional drought
- Exceptional and widespread losses; water emergencies.
The US Drought Monitor is drawn every week by authors at the National Drought Mitigation Center, USDA and NOAA, who weigh rainfall, soil moisture, streamflow, groundwater, vegetation health and reports from local observers. Each map shows conditions through Tuesday morning and is released on Thursday. It shows where drought is and how bad it is; it does not forecast it. CPC's outlooks do that.
