Updated: 8/25/2022



Above normal rainfall over the past 4-5 weeks in central, east central, and southeast Missouri has led to an improvement in drought conditions. Severe (D2) drought has now been eliminated in central and southeast Missouri. However, severe to extreme (D3) drought conditions continue, mainly in southwest parts of the state.




Below is a list of observed precipitation including the departure from normal for
selected sites in Missouri and Illinois. The list includes information from local
airports and cooperative observers since June 1st.

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 found at the web site:

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 Conditions:
Due to recent rainfall, soil moisture percentiles are generally above normal across much of east central and southeast Missouri as well as southwest Illinois. For parts of central and northeast Missouri in addition to west-central Illinois, near normal conditions are being observed with respect to soil moisture.
For the state of Missouri as a whole, topsoil moisture supply was rated 12% very short and 31% short, with subsoil moisture 11% very short and 33% percent short.

Agricultural Impacts:
According to the latest United States Department of Agriculture, corn
condition was rated 12% very poor and 16% poor in the state of Missouri. For soybeans, the condition was rated 7% very poor ad 12% poor as well. Pasture condition was 8% very poor and 16% poor. 
Supply of hay is 4% very short and 35% short, with stock water supply 4%
very short and 22% short.

River and Stream Flow Conditions:

Streamflows are generally at or above normal across much of the region due to recent beneficial rainfall. The Missouri River at Hermann (22nd percentile) and the Middle Fabius River at Ewing (17th percentile) are the exceptions.

Fire Danger Hazards:

The current KBDI: Central Missouri: LOW 

Recent beneficial rainfall has helped alleviate the concern for wild fires. However, parts of southwest Missouri remain more vulnerable than usual due to the persistent dry conditions.

The Keetch-Byram Drought Index (KBDI) is a drought index that is specifically related to fire potential. The KBDI 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 (KBDI)
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 on the Wildland Fire Assessment System (WFAS) web site at:

Precipitation/Temperature Outlooks:

The outlook for the next two weeks favors near normal for both temperatures and precipitation.
