DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE RAPID CITY SD
909 AM MDT THU JUL 12 2016

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

SYNOPSIS...

DROUGHT CONDITIONS AS OF JULY 12. EXTREME (D3) DROUGHT CONDITIONS
CONTINUED ACROSS PORTIONS OF WESTERN SOUTH DAKOTA AND NORTHEASTERN
WYOMING. IN SOUTH DAKOTA THE EXTREME (D3) DROUGHT AREA COVERS THE
EASTERN FOOTHILLS, MAINLY ALONG AND EAST OF INTERSTATE 90 FROM
SPEARFISH TO RAPID CITY. IN NORTHEASTERN WYOMING, EXTREME (D3)
DROUGHT CONDITIONS EXTEND FROM SOUTHWESTERN CROOK COUNTY INTO
CENTRAL WESTON COUNTY. SEVERE (D2) DROUGHT CONDITIONS COVER THE REST
OF WESTON AND CROOK COUNTIES IN WYOMING AND LAWRENCE, SOUTHERN
BUTTE, WESTERN MEADE, WESTERN PENNINGTON AND WESTERN HARDING
COUNTIES IN SOUTH DAKOTA. MODERATE (D1) DROUGHT CONDITIONS COVER
MOST OF CAMPBELL COUNTY WYOMING, THE REST OF HARDING, BUTTE, MEADE,
AND PENNINGTON COUNTIES AS WELL AS PERKINS, ZIEBACH, HAAKON,
JACKSON, WESTERN CUSTER, NORTHWESTERN FALL RIVER, AND WESTERN
MELLETTE COUNTIES. ABNORMALLY DRY (D0) CONDITIONS EXIST ACROSS THE
REST OF NORTHEASTERN WYOMING AND WESTERN SOUTH DAKOTA.

RECENT RAIN HAS HELPED TO KEEP DROUGHT CONDITIONS FROM INTENSIFYING;
HOWEVER, THIS RAINFALL HAS BEEN SPOTTY. AREAS HARDEST HIT BY THE
DRYNESS WERE AROUND THE BLACK HILLS AND BEAR LODGE MOUNTAINS. SEVERE
DROUGHT (D2) ENCAPSULATES AREAS THAT HAVE RECEIVED LESS THAN 60
PERCENT OF NORMAL, WITH LOCALLY LESS THAN 50 PERCENT, RAINFALL OVER
THE PAST 90 DAYS. FURTHERMORE, SATELLITE-DERIVED VEGETATION HEALTH
IMAGERY AS WELL AS RAINFALL DATA INDICATED EXTREME DROUGHT (D3)
CONDITIONS IN A SMALL AREA IMMEDIATELY ADJACENT TO THE BLACK HILLS.

SUMMARY OF IMPACTS...

* DUE TO POOR RANGELAND CONDITIONS, PRODUCERS ARE BEGINNING TO
  REDUCE LIVESTOCK NUMBERS, AND HAY AND GRAIN LOSSES ARE BEGINNING
  TO OCCUR.
* FIRE RESTRICTIONS HAVE BEGUN AND SEVERAL COUNTIES HAVE IMPOSED
  BURN BANS AND ARE PROHIBITING OPEN BURNING.
* DRY FUELS HAVE CAUSED SEVERAL 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.

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. SEVERAL STATIONS ARE NOW REPORTING
PRECIPITATION DECEITS OF TWO TO FIVE INCHES FOR THE YEAR. 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.

PRECIPITATION/TEMPERATURE OUTLOOK...

LA NINA CONDITIONS CONTINUE TO DEVELOP, AS INDICATED BY THE
EXPANSION OF BELOW AVERAGE SEA SURFACE TEMPERATURES (SST) 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, FLOODING, DAMAGING WINDS, AND LIGHTNING WHICH MAY
SPARK FIRES.

NEXT ISSUANCE...

THE NEXT DROUGHT STATEMENT WILL BE ISSUED AROUND JULY 21
