The U.S. Drought Monitor is a weekly collaborative effort between a number of 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 the website:

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, 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.

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 August 4, there was low (fires are not easily started) to moderate (fires start easily and spread at a moderate rate) fire danger in southeast Minnesota, and low fire danger in northeast Iowa and from southwest into central Wisconsin. 

NOTE: This is time-sensitive and conditions could change 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 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 August 4 through August 10, temperatures will average above normal, and precipitation will average near- to above-normal.  During this time frame, daily average temperatures range from 69 to 74°F, and the normal precipitation averages around 9 tenths of an inch. 

Beyond this time frame, the 8 to 14-day forecast (August 11 through August 17) from the Climate Prediction Center (CPC) is calling for enhanced chances of above-normal temperatures and below-normal rainfall. The daily average temperatures for this period range from 68 to 73°F and the normal precipitation is around 9 tenths of an inch. 

From September through November, the Climate Prediction Center has tilted the odds slightly toward warmer- and drier-than-normal. Seasonal temperatures typically average from 40 to 50°F and precipitation ranges from 8 to 9.5 inches.  

Below are the seasonal outlooks for the next year.
