DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE ABERDEEN SD
945 PM CDT TUE AUG 8 2023 /845 PM MDT TUE AUG 8 2023/
...DROUGHT CONDITIONS IN PLACE ACROSS NORTHEAST SOUTH DAKOTA AND
WEST CENTRAL MINNESOTA...
.SYNOPSIS:
.DROUGHT INTENSITY AND EXTENT: ACCORDING TO THE AUGUST 3RD RELEASE OF
THE U.S. DROUGHT MONITOR, SEVERE (D2) DROUGHT CONDITIONS (WHICH FIRST
DEVELOPED IN MID-JULY) CONTINUE TO REMAIN IN PLACE ACROSS NORTHEAST
SOUTH DAKOTA INTO WEST CENTRAL MINNESOTA. THIS INCLUDES EASTERN
ROBERTS, GRANT, EASTERN CODINGTON, BIG STONE, AND TRAVERSE COUNTIES.
MODERATE (D1) DROUGHT CONDITIONS ALSO COVER A PORTION OF NORTHEAST
SOUTH DAKOTA, INCLUDING WESTERN ROBERTS, EASTERN DAY, CODINGTON,
EASTERN HAMLIN, AND DEUEL COUNTIES. ALSO INCLUDED IN D1 DROUGHT ARE
AREAS FURTHER SOUTH, COVERING BUFFALO, SOUTHERN HAND, AND EASTERN
LYMAN COUNTIES. THE PERCENTAGE OF THE ABERDEEN COUNTY WARNING AREA
(CWA) IN MODERATE (D1) DROUGHT OR WORSE IS AT 21.03 PERCENT. THIS IS
DOWN FROM 43.06 PERCENT COMPARED TO CONDITIONS IN MID JUNE.
.PRECIPITATION: THERE HAVE BEEN ENOUGH EPISODES OF RAINFALL ACROSS
CENTRAL SOUTH DAKOTA OVER THE PAST 60 DAYS TO WHERE MOST OF THE AREA
HAS STAYED WET. OVER NORTHEAST SOUTH DAKOTA AND WEST CENTRAL
MINNESOTA, 60-DAY PRECIPITATION HAS ONLY BEEN 50 TO 70 PERCENT OF
NORMAL FOR MUCH OF THE AREA ALONG AND EAST OF I-29. DEFICITS THE PAST
30 DAYS ARE AROUND 25 TO 50 PERCENT OF NORMAL FOR GENERALLY THE SAME
AREA. A HEAVY RAIN EVENT FROM AUGUST 4TH-6TH BROUGHT A LARGE SWATH
OF 1 TO 5 INCHES OF RAINFALL ACROSS A GOOD PORTION OF THE FORECAST
AREA, WITH LOCALLY HIGHER AMOUNTS. ALTHOUGH, THE CURRENT AREAS IN D1
AND D2 DROUGHT MISSED OUT ON SOME OF THESE HIGHER TOTALS, THUS
KEEPING LONGER TERM DEFICITS IN PLACE.
.TEMPERATURES: OVER THE PAST 60 DAYS, TEMPERATURES HAVE BEEN SOMEWHAT
VARIABLE ACROSS THE REGION, WITH EPISODES OF ABOVE AND BELOW NORMAL
TEMPERATURES. ON AVERAGE, MOST AREAS HAVE BEEN WITHIN A DEGREE OR TWO
OF NORMAL, WITH A FEW POCKETS OF COOLER THAN AVERAGE (NORTH CENTRAL
SOUTH DAKOTA) AND WARMER THAN AVERAGE (PARTS OF NORTHEAST SOUTH
DAKOTA) OVER THE PAST 60 DAYS.
.HYDROLOGIC CONDITIONS: CURRENT 7-DAY AVERAGE STREAMFLOWS ARE NORMAL
TO MUCH ABOVE NORMAL ACROSS THE REGION, LARGELY IN PART FROM THE
HEAVY RAINFALL EVENT IN EARLY AUGUST. BUT, GOING BACK TO 28-DAY
AVERAGES, AND IT'S DISCOVERED THAT PARTS OF THE BIG SIOUX RIVER
WITHIN THE CURRENT DROUGHT AREA SHOW BELOW NORMAL STREAMFLOWS. THE
BIG SIOUX RIVER NEAR FLORENCE IS AT THE 22ND PERCENTILE, WHILE THE
BIG SIOUX RIVER AT WATERTOWN IS ALSO AT THE 22ND PERCENTILE.
.SUMMARY OF IMPACTS:
.AGRICULTURAL IMPACTS: THE AUGUST 7TH RELEASE OF THE SOUTH DAKOTA
CROP PROGRESS AND CONDITION FROM NASS (NATIONAL AGRICULTURAL
STATISTICS SERVICE) RATED TOPSOIL MOISTURE 37 PERCENT SHORT OR VERY
SHORT. SUBSOIL MOISTURE WAS RATED 44 PERCENT SHORT OR VERY SHORT.
THESE NUMBERS ARE DOWN FROM 53 PERCENT (FOR BOTH TOPSOIL AND SUBSOIL)
WHICH WAS REPORTED BACK IN MID JUNE. CORN CONDITION WAS RATED 13
PERCENT POOR OR VERY POOR. SOYBEANS WERE RATED 12 PERCENT POOR OR
VERY POOR. SPRING WHEAT IS SHOWING 32 PERCENT POOR OR VERY POOR.
PASTURE AND RANGE CONDITION WAS RATED 19 PERCENT POOR OR VERY POOR.
.HYDROLOGIC IMPACTS: NONE KNOWN AT THIS TIME.
.FIRE HAZARDS: FIRE ACTIVITY ACROSS CENTRAL SOUTH DAKOTA INTO WEST
CENTRAL MINNESOTA HAS BEEN SOMEWHAT LOW. AN ABUNDANCE OF MOISTURE
OVER PORTIONS OF THE REGION HAVE KEPT FUELS DIFFICULT TO PROMOTE
LARGE FIRE GROWTH. FIRE DANGER HAS MOSTLY BEEN LOW THUS FAR DURING
THE SUMMER MONTHS. WILL HAVE TO WATCH EASTERN AREAS WHERE D1 AND D2
DROUGHT CONDITIONS ARE IN PLACE, AND WHERE FUELS HAVE BEGUN TO SLOWLY
CURE.
.DROUGHT MITIGATION ACTIONS: NONE KNOWN AT THIS TIME.
.LOCAL DROUGHT OUTLOOK: THE U.S. MONTHLY DROUGHT OUTLOOK VALID FOR
AUGUST AND ISSUED ON JULY 31ST CALLS FOR "DROUGHT PERSISTENCE"
ACROSS NORTHEAST SOUTH DAKOTA AND WEST CENTRAL MINNESOTA WHERE
CURRENT D1 AND D2 DROUGHT CONDITIONS ARE IN PLACE. DROUGHT REMOVAL IS
LIKELY ACROSS SOUTH CENTRAL AND SOUTHEAST SOUTH DAKOTA. THE SEASONAL
OUTLOOK ISSUED ON JULY 31ST, WHICH IS VALID AUGUST THROUGH OCTOBER,
CALLS FOR "DROUGHT REMOVAL OR IMPROVEMENT" OVER ALL OF
EASTERN/SOUTHEASTERN SOUTH DAKOTA AND WEST CENTRAL MINNESOTA.
.NEXT ISSUANCE DATE: THIS PRODUCT WILL BE UPDATED IN EARLY SEPTEMBER
IF D2 (SEVERE) DROUGHT CONDITIONS PERSIST OVER ANY PORTION OF THE
FORECAST AREA, OR SIGNIFICANT CHANGES ARE NOTED.
