IN ALL OR PARTS OF CHARLES MIX, YANKTON, CLAY AND UNION COUNTIES

IN NORTHWEST IOWA. MODERATE DROUGHT (D1) HAS BEEN INTRODUCED IN  
THE LAST 4 WEEKS IN BRULE, AURORA, DAVISON, HANSON, MCCOOK,  
MINNEHAHA AND MOODY COUNTIES IN SOUTH DAKOTA, AND PIPESTONE,  
LINCOLN, AND LYON COUNTIES IN SOUTHWEST MINNESOTA. THE PERCENTAGE  
OF THE FORECAST AREA IN D3 IS 11.68 PERCENT, UP FROM 7.99 PERCENT  
IN EARLY JULY. THE TOTAL PERCENTAGE OF THE FORECAST AREA IN D2 HAS  
INCREASED FROM 19.39 PERCENT ON JULY 5 TO 29.88 PERCENT  
CURRENTLY. THE PERCENTAGE OF THE AREA IN MODERATE DROUGHT (D1) OR  
WORSE HAS INCREASED IN THE PAST MONTH FROM 31.59 PERCENT TO 55.45  
PERCENT CURRENTLY. THE PORTION OF THE REGION NOT DEPICTED WITH  
ANY DROUGHT OR DRYNESS HAS DECREASED FROM 37.96 PERCENT TO 18.73  
PERCENT IN THE PAST MONTH.  
 
.PRECIPITATION: IN THE LAST WEEK, AREAS ALONG AND NORTH OF I-90,  
AS WELL AS AREAS RIGHT ALONG THE MISSOURI RIVER FROM FORT RANDALL  
DAM TO VERMILLION, RECEIVED BETWEEN 0.25 INCH AND 1.50 INCHES,  
WHICH IS BETWEEN 50 TO 150 PERCENT OF NORMAL. MOST OF THE REST OF  
THE REGION GENERALLY RECEIVED LESS THAN 0.10 INCH OF RAIN IN THE  
PAST WEEK. FOR THE LAST MONTH, MOST OF THE REGION HAS AVERAGED  
BETWEEN 25 AND 90 PERCENT OF NORMAL, WITH A NARROW BAND OF ABOVE  
NORMAL RAINFALL FROM NEAR HURON TO SIOUX FALLS TO JACKSON MN.  
 
.TEMPERATURE: TEMPERATURES FOR THE LAST WEEK HAVE AVERAGED  
BETWEEN 2 DEGREES ABOVE OR BELOW NORMAL. FOR THE LAST 90 DAYS,  
TEMPERATURES HAVE AVERAGED BETWEEN 1 AND 3 DEGREES ABOVE NORMAL.  
 
.HYDROLOGIC CONDITIONS: CURRENT STREAMFLOWS ARE RUNNING NORMAL TO  
ABOVE NORMAL ON THE JAMES, UPPER BIG SIOUX, LITTLE SIOUX, REDWOOD  
AND DES MOINES RIVERS, AND MAINLY BELOW TO MUCH BELOW NORMAL ON  
THE VERMILLION, LOWER BIG SIOUX, FLOYD, AND OCHEYEDAN RIVERS.  
GROUND WATER LEVELS NORTH OF SIOUX FALLS AND IN NORTHEAST NEBRASKA  
ARE CURRENTLY IN THE NORMAL TO BELOW NORMAL RANGES.  
 
.SOIL MOISTURE CONDITIONS: CURRENT SOIL MOISTURE ANOMALIES ARE  
AROUND 2 INCHES BELOW NORMAL ALONG THE HIGHWAY 14 CORRIDOR,  
WORSENING TO 3 TO 5 INCHES BELOW NORMAL SOUTH OF I-90.  
 
.SUMMARY OF IMPACTS:  
 
.AGRICULTURAL IMPACTS: SOME CORN CROPS WILL BE LOSING YIELD DUE TO  
LACK OF MOISTURE AND HIGH HEAT DURING THE TASSELING AND  
POLLINATION PHASES. IN SOME AREAS, THE CORN IS NOT EVEN SUITABLE  
FOR CUTTING FOR SILAGE DUE TO BEING TOO DRY. IN SOUTH-CENTRAL  
SOUTH DAKOTA, SOME PASTURES HAVE BECOME TOO DRY AND SHORT FOR  
PUTTING CATTLE ON THEM, AND MANY PEOPLE ARE SAYING THAT THERE WILL  
NOT BE A THIRD CUTTING OF HAY.  
 
.HYDROLOGIC IMPACTS: NONE KNOWN AT THIS TIME.  
 
.FIRE HAZARDS: SHORT TERM FUELS ARE DRYING, AND THERE ARE REPORTS  
OF EASY IGNITION OF GRASSLAND OR PASTURE FIRES, BUT SO FAR THESE  
HAVE BEEN QUICKLY CONTROLLED AND THE SPREAD OF THESE SMALL FIRES  
HAS NOT BEEN GREAT.  
 
.DROUGHT MITIGATION ACTIONS: NONE REPORTED.  
 
.LOCAL DROUGHT OUTLOOK: THE LATEST SEASONAL DROUGHT OUTLOOK FROM  
THE CLIMATE PREDICTION CENTER SHOWS THAT THE DROUGHT IS EXPECTED  
TO PERSIST THROUGH THE END OF SEPTEMBER IN THOSE AREAS ALREADY IN  
D1 AND D2, AND DROUGHT DEVELOPMENT IS LIKELY ACROSS THE AREAS OF  
NORTHWESTERN IOWA NOT CURRENTLY AT D1 OR WORSE.  
 
THE LATEST 6-10 DAY, 8-14 DAY AND 3-4 WEEK OUTLOOKS SHOW  
INCREASED PROBABILITIES FOR ABOVE NORMAL TEMPERATURES AND BELOW  
NORMAL PRECIPITATION FOR NEARLY THE ENTIRE AREA. THE 3 MONTH  
OUTLOOK FOR AUGUST THROUGH OCTOBER ALSO SHOWS INCREASED CHANCES  
FOR ABOVE NORMAL TEMPERATURES AND BELOW NORMAL PRECIPITATION.  
 
.NEXT ISSUANCE DATE: THE PRODUCT WILL BE UPDATED AROUND AUGUST  
25, UNLESS CONDITIONS OR OUTLOOKS CHANGE SIGNIFICANTLY.
