DROUGHT INFORMATION STATEMENT  
NATIONAL WEATHER SERVICE SAINT LOUIS MO  
1248 AM CDT FRI AUG 12 2022  
 
...DROUGHT CONDITIONS CONTINUE TO IMPROVE IN SOUTHEAST MISSOURI,  
LINGERS OVER PORTIONS OF CENTRAL MISSOURI...  
 
SYNOPSIS...  
 
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. DROUGHT IMPACTS THUS FAR HAVE BEEN CONFINED TO THE  
AGRICULTURAL SECTOR. MORE SPECIFICALLY, PASTURE CONDITIONS ALONG  
WITH HAY AND STOCK WATER SUPPLIES HAVE DETERIORATED OVER THE PAST  
SEVERAL WEEKS. 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, 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 DROUGHT CONTINUES ACROSS PORTIONS OF BOONE AND  
NORTHERN MONITEAU COUNTIES.  
 
SUMMARY OF IMPACTS...  
 
ACCORDING TO THE LATEST UNITED STATES DEPARTMENT OF AGRICULTURE,  
SOYBEAN CONDITION WAS RATED 8 PERCENT VERY POOR AND 13 PERCENT  
POOR IN THE STATE OF MISSOURI. FOR CORN, 12 PERCENT WAS RATED  
VERY POOR AND 13 PERCENT POOR AS WELL ACROSS THE STATE. PASTURE  
CONDITION WAS 13 PERCENT VERY POOR AND 33 PERCENT POOR.  
 
SUPPLY OF HAY IS 4 PERCENT VERY SHORT AND 30 PERCENT SHORT, WITH  
STOCK WATER SUPPLY 7 PERCENT VERY SHORT AND 23 PERCENT SHORT.  
 
TOPSOIL MOISTURE SUPPLY WAS RATED 16 PERCENT VERY SHORT AND 34  
PERCENT SHORT, WITH SUBSOIL MOISTURE 16 PERCENT VERY SHORT AND 33  
PERCENT SHORT.  
 
CLIMATE SUMMARY...  
 
AFTER A WET SPRING, LARGELY BELOW NORMAL RAINFALL HAS BEEN  
OBSERVED SINCE THE START OF METEOROLOGICAL SUMMER (JUNE 1ST)  
IN CENTRAL MISSOURI. IN SOME LOCATIONS, DEPARTURES OF 2-5 INCHES  
ARE COMMON.  
 
IN ADDITION TO THE BELOW-NORMAL RAINFALL, MUCH OF THIS PERIOD HAS  
ALSO BEEN VERY WARM COMPARED TO CLIMATOLOGY. THE COMBINATION OF  
DRY, HOT CONDITIONS INCREASES EVAPOTRANSPIRATION POTENTIAL.  
 
PRECIPITATION/TEMPERATURE OUTLOOK...  
 
THE OUTLOOK FROM THE CLIMATE PREDICTION CENTER (CPC) FOR THE DAYS  
6-10 PERIOD FAVORS BELOW NORMAL TEMPERATURES AND NEAR TO ABOVE  
NORMAL RAINFALL.  
 
IN THE WEEK 2 TIMEFRAME, THE CPC CONTINUES TO FAVOR BELOW NORMAL  
TEMPERATURES AND NEAR TO ABOVE NORMAL PRECIPITATION ACROSS THE  
MID-MISSISSIPPI VALLEY. IF THESE OUTLOOKS COME TRUE, DROUGHT  
CONDITIONS MAY IMPROVE IN CENTRAL MISSOURI.  
 
HYDROLOGIC SUMMARY AND OUTLOOK...  
 
DUE TO THE RECENT HEAVY RAINFALL EVENTS, MUCH OF THE REGION HAS  
ABOVE TO WELL-ABOVE AVERAGE STREAMFLOWS. HOWEVER, GENERALLY NEAR  
NORMAL FLOWS ARE OBSERVED IN NORTHEASTERN MISSOURI AND WEST-  
CENTRAL ILLINOIS. IN CENTRAL MISSOURI, NEAR TO BELOW NORMAL  
STREAMFLOWS ARE OBSERVED, INCLUDING THE MARIES RIVER AT WESTPHALIA  
WHERE THE 7-DAY AVERAGE STREAMFLOW IS ONLY IN THE 23RD PERCENTILE  
OF CLIMATOLOGY.  
 
NEXT ISSUANCE DATE...  
 
THE NEXT ISSUANCE WILL BE ON OR BEFORE THURSDAY AUGUST 25TH,  
2022.
