After a fairly wet spring, portions of central and southeast Missouri have experienced below normal rainfall. Below-normal rainfall combined with a hot June and July led to drought conditions. Most of the impacts have been confined to the agricultural sector. More specifically, pasture conditions along with hay and stock water supplies have deteriorated over the past month. In addition, crops such as corn and soybeans are also being negatively impacted, particularly in areas where these crops were planted late due to the wet conditions in the spring.
Over the past few weeks, above to well-above normal rainfall has been experienced across much of the area. In eastern Missouri, a stripe of 8-12+ inches of rain has fallen since mid July. This rainfall has completely eliminated any drought or abnormally dry conditions. However, portions of central Missouri have largely missed out on the heavier rainfall events the past few weeks. Therefore, severe (D2) drought continues across portions of Boone and northern Moniteau counties.




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 16% very short and 34% short, with subsoil moisture 16% 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 13% poor in the state of Missouri. For soybeans, the condition was rated 8% very poor ad 13% poor as well. Pasture condition was 13% very poor and 33% poor. 
Supply of hay is 4% very short and 30% short, with stock water supply 7%
very short and 23% short.

River and Stream Flow Conditions:

Streamflows are generally at or above normal across much of the region due to recent beneficial rainfall. One of the exceptions in central Missouri is the Maries River at Westphalia where the 7-day average streamflow is only in the 23rs percentile of climatology.

Fire Danger Hazards:

The current KBDI: Central Missouri: MODERATE 

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 below normal temperatures and near to above normal precipitation.
