DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE RAPID CITY SD
855 AM MDT THU SEP 15 2016

...IMPROVEMENT IN DROUGHT CONDITIONS ACROSS WESTERN SOUTH DAKOTA AND
NORTHEASTERN WYOMING...

SYNOPSIS... CHILLY, WET WEATHER IMPROVED DROUGHT CONDITIONS, THOUGH
IMPACTS REMAINED. TEMPERATURES FOR THE WEEK AVERAGED 2 TO 8 DEGREES
BELOW NORMAL, WHICH COUPLED WITH WIDESPREAD RAIN, LED TO REDUCTIONS
OF DRYNESS AND DROUGHT. THIS WEEK`S PRECIPITATION COMBINED WITH A
WETTER-THAN-NORMAL PERIOD DATING BACK OVER THE PAST 30 DAYS LED TO
THE REDUCTION OF MODERATE TO SEVERE DROUGHT (D1 AND D2,
RESPECTIVELY). SATELLITE-DERIVED VEGETATION HEALTH DATA AS WELL AS
REPORTS FROM THE FIELD, CONTINUE TO SHOW IMPROVING CONDITIONS FROM
THIS SUMMER`S LOCALLY EXTREME DROUGHT (D3). DESPITE THE COOLER
WEATHER AND RECENT RAIN, IMPACTS LINGERED IN THE D2 AND D3 AREAS,
WITH 90-DAY RAINFALL REMAINING LOCALLY LESS THAN 50 PERCENT OF
NORMAL.

EXTREME (D3) DROUGHT CONDITIONS COVERED SOUTHWESTERN HARDING AND
NORTHWESTERN BUTTE COUNTIES IN SOUTH DAKOTA. SEVERE (D2) DROUGHT
CONDITIONS COVERED PORTIONS OF NORTHERN AND SOUTHWESTERN CROOK, MOST
OF WESTON, AND EASTERN CAMPBELL COUNTIES IN NORTHEASTERN WYOMING. IN
WESTERN SOUTH DAKOTA, SEVERE (D2) DROUGHT CONDITIONS COVERED
SOUTHERN HARDING, NORTHERN BUTTE, FAR SOUTHWESTERN PERKINS, FAR
NORTHWESTERN MEADE, FAR WESTERN CUSTER, AND WESTERN FALL RIVER
COUNTIES. MODERATE (D1) DROUGHT CONDITIONS COVERED THE REST OF CROOK
AND CAMPBELL COUNTIES IN WYOMING, THE REST OF FALL RIVER, CUSTER,
MEADE, BUTTE, HARDING, AND PERKINS COUNTIES AS WELL AS LAWRENCE,
PENNINGTON, ZIEBACH, AND WESTERN OGLALA LAKOTA COUNTIES. ABNORMALLY
DRY (D0) CONDITIONS COVERED BENNETT, SOUTHWESTERN MELLETTE,
NORTHWESTERN TODD, JACKSON, HAAKON AND THE REST OF OGLALA LAKOTA
COUNTIES.

SUMMARY OF IMPACTS...

* DUE TO POOR RANGELAND CONDITIONS PRODUCERS ARE REDUCING LIVESTOCK
  NUMBERS, DELAYING THE PLANTING OF WINTER WHEAT, AND HAY AND GRAIN
  LOSSES CONTINUE TO OCCUR.
* RANCHERS AND FARMERS ARE EXPERIENCING LITTLE IF ANY HAY PRODUCTION.
* FIRE RESTRICTIONS CONTINUE AND SEVERAL COUNTIES HAVE IMPOSED BURN
  BANS AND ARE PROHIBITING OPEN BURNING.
* DRY FUELS HAVE CONTRIBUTED TO SEVERAL WILDFIRES 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
WERE EXTREMELY DRY WITH MOST LOCATIONS RECEIVING ONLY A THIRD OF
THEIR TYPICAL RAINFALL. IN JULY, RAINFALL AMOUNTS VARIED WITH SOME
LOCATIONS REPORTING BELOW AVERAGE AMOUNTS AND OTHER SPOTS ABOVE
AVERAGE. IN AUGUST, RAINFALL AMOUNTS IN MOST LOCATIONS WERE ABOVE
AVERAGE; THE EXCEPTION WAS OVER FAR NORTHWESTERN SOUTH DAKOTA AND
FAR SOUTH WESTERN SOUTH DAKOTA, WHERE RAINFALL AMOUNTS WERE SLIGHTLY
BELOW AVERAGE. SO FAR THE FIRST HALF OF SEPTEMBER HAS BEEN WET AND
COOL.

PRECIPITATION/TEMPERATURE OUTLOOK...

SEA SURFACE TEMPERATURES (SST) ACROSS THE EQUATORIAL PACIFIC OCEAN
ARE REMAINING NEAR AVERAGE. THIS TREND IS EXPECTED TO CONTINUE
THROUGH THE FALL.

THE OUTLOOK FOR THE REST OF SEPTEMBER IS FOR AROUND AVERAGE
TEMPERATURES WITH AVERAGE PRECIPITATION.

NEXT ISSUANCE...

THE NEXT DROUGHT STATEMENT WILL BE ISSUED TOWARD THE END OF
SEPTEMBER.
