DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE RAPID CITY SD
1040 AM MDT THU JUL 28 2016

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

SYNOPSIS...

DROUGHT CONDITIONS AS OF JULY 28. EXTREME (D3) DROUGHT CONDITIONS
COVERED 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 INCLUDED 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.

TEMPERATURES FOR THE PAST WEEK HAVE BEEN CLOSER TO AVERAGE; HOWEVER,
RECENT RAIN HAS BEEN SPOTTY. 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.

THE OUTLOOK FOR EARLY AUGUST INDICATES TEMPERATURES WILL BE NEAR
AVERAGE AND THERE IS A GREATER CHANCE FOR ABOVE-AVERAGE
PRECIPITATION. ALSO, 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 AUGUST 4.
