DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE RAPID CITY SD
900 AM MDT THU JUL 21 2016

... DROUGHT CONDITIONS INTENSIFY ACROSS WESTERN SOUTH DAKOTA AND
NORTHEASTERN WYOMING...

SYNOPSIS...

DROUGHT CONDITIONS AS OF JULY 21. EXTREME (D3) DROUGHT CONDITIONS
WERE EXPANDED TO COVER MOST OF CROOK AND WESTON COUNTIES IN
NORTHEASTERN WYOMING AND LAWRENCE, SOUTHERN BUTTE, WESTERN MEADE,
WESTERN PENNINGTON, AND PORTIONS OF WESTERN HARDING COUNTIES IN
SOUTH DAKOTA. SEVERE (D2) DROUGHT CONDITIONS WERE EXPANDED TO
INCLUDE EASTERN CAMPBELL COUNTY AND THE REST OF CROOK AND WESTON
COUNTIES IN NORTHEASTERN WYOMING. IN SOUTH DAKOTA, SEVERE (D2)
DROUGHT CONDITIONS COVERED THE REST OF HARDING, BUTTE, AND MEADE
COUNTIES AS WELL AS SOUTHWESTERN PERKINS, CENTRAL PENNINGTON, AND
WESTERN CUSTER COUNTIES. MODERATE (D1) DROUGHT CONDITIONS COVERED
THE REST OF CAMPBELL COUNTY WYOMING, THE REST OF PENNINGTON, CUSTER,
AND PERKINS COUNTIES AS WELL AS ZIEBACH, HAAKON, FALL RIVER,
NORTHERN AND WESTERN OGLALA LAKOTA, JACKSON, MELLETTE, AND NORTHERN
TRIPP COUNTIES. ABNORMALLY DRY (D0) DROUGHT CONDITIONS COVERED THE
REST OF WESTERN SOUTH DAKOTA.

RECENT RAIN HAS BEEN SPOTTY, WITH MOST AREAS NOT RECEIVING
SIGNIFICANT RAINFALL. THE HARDEST HIT LOCATIONS ARE REPORTING
RAINFALL DEFICITS OF FOUR TO EIGHT INCHES WITH THESE LOCATIONS BEING
AREAS AROUND AND ADJACENT TO THE BLACK HILLS. 28-DAY STREAM FLOWS
ARE MEASURING IN THE 5-10 PERCENT CATEGORY AND LOWER. ALL OTHER
INDICATORS, INCLUDING MODEL-BASED AND SATELLITE-DERIVED, ARE
POINTING TO AN EXTREME LOCALIZED DROUGHT IN THE AREA.

SUMMARY OF IMPACTS...

* DUE TO POOR RANGELAND CONDITIONS, PRODUCERS ARE BEGINNING TO
  REDUCE LIVESTOCK NUMBERS, AND HAY AND GRAIN LOSSES ARE BEGINNING
  TO OCCUR.
* RANCHERS AND FARMERS ARE EXPERIENCING NO HAY PRODUCTION AT ALL AND
  CATTLE ARE ALREADY ON WINTER PASTURES.
* FIRE RESTRICTIONS HAVE BEGUN AND SEVERAL COUNTIES HAVE IMPOSED
  BURN BANS AND ARE PROHIBITING OPEN BURNING.
* DRY FUELS HAVE CAUSED SEVERAL LARGE WILDFIRES SO FAR THIS YEAR.
* STOCK PONDS AND DUGOUTS ARE LOW, WHICH IS LIMITING WATER FOR
  CATTLE AND OTHER ANIMALS. WATER AT SUCH LOW LEVELS TYPICALLY IS
  OF POOR QUALITY.
* SOME RANCHERS HAVE TO HAUL WATER IN EVERY DAY.

CLIMATE SUMMARY...

SO FAR THIS YEAR TEMPERATURES HAVE BEEN ABOVE AVERAGE. MAY AND JUNE
HAVE BEEN EXTREMELY DRY WITH MOST LOCATIONS RECEIVING ONLY A THIRD
OF THEIR TYPICAL RAINFALL. THREE STATIONS, FORT MEADE (STURGIS),
NEWELL, AND DEVILS TOWER, REPORTED THEIR DRIEST MAY ON RECORD. FOR
JUNE, SEVERAL LOCATIONS REPORTED ONE OF THEIR WARMEST JUNES SINCE
1988, AND AT A FEW STATIONS, JUNE 2016 WAS RANKED AS ONE OF THE
DRIEST JUNES ON RECORD.

SO FAR IN JULY, THE ABOVE-AVERAGE TEMPERATURES HAVE CONTINUED.
PRECIPITATION IS ONCE AGAIN AVERAGING BELOW NORMAL FOR MOST AREAS.

PRECIPITATION/TEMPERATURE OUTLOOK...

LA NINA CONDITIONS CONTINUE TO DEVELOP, AS INDICATED BY THE
EXPANSION OF BELOW-AVERAGE SEA SURFACE TEMPERATURES ACROSS THE
EASTERN EQUATORIAL PACIFIC OCEAN. LA NINA TYPICALLY FAVORS CONTINUED
DRY CONDITIONS THROUGH THE FALL.

THE OUTLOOK THROUGH THE END OF JULY INDICATES THERE IS A GREATER
CHANCE FOR ABOVE-AVERAGE TEMPERATURES AND BELOW-AVERAGE
PRECIPITATION. HOWEVER, THUNDERSTORMS WILL BE POSSIBLE DURING THIS
TIME AND SOME OF THESE STORMS MAY CONTAIN DANGEROUS SEVERE WEATHER
INCLUDING HAIL, DAMAGING WINDS, FLOODING, AND LIGHTNING (WHICH MAY
SPARK FIRES).

NEXT ISSUANCE...

THE NEXT DROUGHT STATEMENT WILL BE ISSUED AROUND JULY 28
