The U.S. Drought Monitor is a weekly collaborative effort between several federal agencies including NOAA/NWS, U.S. Department of Agriculture, and the National Drought Mitigation Center. Details and explanations of the Drought Monitor can be found at:

U.S. Drought Monitor

The categories of drought are defined as follows:

Abnormally Dry (D0)
- Going into drought: short-term dryness slowing planting, growth of crops or pastures; fire risk above average. Coming out of drought: some lingering water deficits; pastures or crops not fully recovered.

Moderate Drought (D1) - Some damage to crops and pastures; fire risk high; streams, reservoirs, or wells low, some water shortages developing or imminent, voluntary water use restrictions requested.

Severe Drought (D2) - Crop or pasture losses likely; fire risk very high; water shortages common; water restrictions imposed.

Extreme Drought (D3) - Major crop/pasture losses; extreme fire danger; widespread water shortages or restrictions.

Exceptional Drought (D4) - Exceptional and widespread crop/pasture losses; exceptional fire risk; shortages of water in reservoirs, streams, and wells, creating water emergencies.

Agricultural Impacts:

Here are the latest Agricultural Statistics Service reports for Iowa, Minnesota, and Wisconsin issued on April 28, 2025.

Iowa

While some producers were able to get into their fields, precipitation continued to delay planting in many parts of the State, allowing only 3.2 days suitable for fieldwork.

  • Topsoil moisture condition rated 3 percent very short, 9 percent short, 76 percent adequate and 12 percent surplus. 
  • Subsoil moisture condition rated 4 percent very short, 18 percent short, 71 percent adequate and 7 percent surplus.

Corn planted reached 49 percent, 3 days ahead of last year but 2 days behind the 5-year average. Corn emerged reached 10 percent, 2 days ahead of last year’s pace and 3 days ahead of normal. Thirty-eight percent of the expected soybean crop has been planted, one week ahead of last year and 2 days ahead of the 5-year average. Soybeans emerged reached 5 percent. Oats seeding reached 91 percent complete. Fifty-eight percent of the expected oat acreage has emerged, 4 days behind last year but 3 days ahead of normal. The first oat condition rating of the season was 1 percent very poor, 2 percent poor, 18 percent fair, 66 percent good and 13 percent excellent.

Pasture condition rated 60 percent good to excellent. No livestock issues were reported.

Minnesota

Minnesota farmers averaged 3.6 days suitable for fieldwork during the week. Most of the state received some much-needed rain, but it did slow down planting in some areas. No livestock issues were reported.

  • Topsoil moisture supplies were rated 3 percent very short, 14 percent short, 75 percent adequate, and 8 percent surplus. 
  • Subsoil moisture supplies were rated 3 percent very short, 23 percent short, 69 percent adequate, and 5 percent surplus.

Corn planting was 44 percent complete, putting planting progress two days ahead of 2024. Soybeans were 22 percent planted, reaching that level five days
earlier than a year ago. Both corn and soybeans were a day ahead of the five-year average.

Barley planting was 22 percent complete, with 5 percent of the 2024 crop emerged. Oats reached 51 percent planted and 15 percent emerged, and spring wheat was 30 percent planted and 5 percent emerged. Dry edible beans reached 10 percent planted, potatoes reached 23 percent, sugar beets 77 percent, and sunflowers 4 percent.

Pasture condition was rated 2 percent very poor, 5 percent poor, 43 percent fair, 43 percent good, and 7 percent excellent.

Wisconsin

Wisconsin had 3.2 days suitable for fieldwork statewide for the week. Rainy conditions, especially in northern areas of the state hampered planting efforts. Pastures, hay and small grains benefited from the moisture.

  • Topsoil moisture condition rated 0 percent very short, 7 percent short, 66 percent adequate and 27 percent surplus. 
  • Subsoil moisture condition rated 1 percent very short, 11 percent short, 66 percent adequate and 22 percent surplus.

Corn planting was 16 percent complete, 2 days behind both last year and the 5-year average. Scattered corn emergence was reported in a few counties.

Soybeans were 17 percent planted, 2 days behind last year but 1 day ahead of the average.

Oat planting was 36 percent complete, 7 days behind last year and 5 days behind the average. Oats were 10 percent emerged.

Potato planting reached 55 percent complete, 9 days behind last year but nearly even with the average.

Spring tillage was 42 percent complete, 7 days behind last year and 3 days behind the average.

The first all hay condition rated 1 percent very poor, 6 percent poor, 25 percent fair, 55 percent good and 13 percent excellent.

Winter wheat condition was rated 63 percent good to excellent, up 5 percentage points from last week.

Pasture and range condition was rated 47 percent good to excellent, up 10 percentage points from last week.

Soil moisture supply measures how much moisture is present in cropland topsoil during the week. Soil moisture is reported as a percentage. The categories very short, short, adequate, and surplus must add up to 100%.

Very Short - Soil moisture supplies are significantly less than what is required for normal plant development. Growth has been stopped, or nearly so, and plants are showing visible signs of moisture stress. Under these conditions, plants will quickly suffer irreparable damage.

Short - Soil dry.  Seed germination and/or normal crop growth and development would be curtailed.

Adequate - Soil moist.  Seed germination and/or crop growth and development would be normal or unhindered.

Surplus - Soil wet.  Fields may be muddy and will generally be unable to absorb additional moisture.  Young developing crops may be yellowing from excess moisture.

Fire Danger Hazards:

As of the morning of May 6, fire danger was high (fires start easily and spread at a fast rate) to very high (fires start easily and spread at a very fast rate) in central Wisconsin. Meanwhile, there was high fire danger in southeast Minnesota, moderate (fires start easily and spread at a moderate rate) fire danger in southwest and west-central Wisconsin, and low (fires are not easily started) fire danger in northeast Iowa.

NOTE: This is time-sensitive and conditions could change from day to day. Fire conditions can change drastically on drier, windy days. Updated DNR fire conditions can be found via links to the right.

Citizens should always check with local officials in their area before undertaking any outside burning. Citizens are liable for damages and suppression costs of any wildfire they may start.

Description of Fire Danger Ratings

For updated DNR Fire Conditions consult the following Web Sites:

The Keetch-Byram Drought Index (KBDI) is a drought index that is specifically related to fire potential. The KDBI is broken into four categories which indicate the susceptibility of ground fuels to fire danger. Below are the four categories and a brief description of each.

Keetch-Byram Drought Index (KDBI)
KBDI Value
Description of Fire Potential
0 to 200
Low - Wet with little danger of fire initiation
201 to 400
Moderate - Drying occurring with some fire danger
401 to 600
High - Ground cover is dry and will burn readily
601 to 800
Extreme - Dead and live fuels will burn readily

KBDI and Dead Fuel Moisture data can be found through the:

Precipitation/Temperature Outlooks:

From May 8 through May 15, temperatures will average above normal, and precipitation will average below normal. During this time frame, daily average temperatures range from 54 to 59°F, and precipitation averages around an inch. 

From May 16 through May 22 (8-14 day outlook), the Climate Prediction Center (CPC) has near to above-normal temperatures and above-normal precipitation (33-40%). The normal daily average temperatures for this period range from 57 to 62°F and the normal precipitation is around an inch. 

For meteorological summer (June 1 through August 31), CPC has the odds tilted slightly toward warmer-than-normal temperatures (33-40%) and below-normal precipitation (33-50% - highest west of the Mississippi River) in the Upper Mississippi River Valley. Seasonal temperatures range from 65 to 75°F (highest along the Mississippi River and in northeast Iowa and southwest Wisconsin). Seasonal precipitation ranges from 12 to 13" north of Interstate 94 and from 13 to 15" across the remainder of the area.

Below are the seasonal outlooks for the next year.
