DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE RAPID CITY SD
235 PM MDT THU DEC 1 2016

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

SYNOPSIS...

EXCEPTIONALLY WARM TEMPERATURES AND VERY DRY CONDITIONS IN OCTOBER
AND NOVEMBER HAVE LED TO PERSISTENT DROUGHT CONDITIONS FOR MOST OF
WESTERN SOUTH DAKOTA AND NORTHEASTERN WYOMING. SOME OF THESE AREAS
HAVE EXPERIENCED THESE CONDITIONS SINCE MAY. RECENT COLD TEMPERATURES
HAVE CAUSED THE GROUND TO FREEZE; THEREFORE, ANY MELTING SNOW WILL
HAVE A DIFFICULT TIME IMPROVING SOIL MOISTURE CONDITIONS. THIS WILL
RESULT IN AREAS OF DROUGHT PERSISTING THROUGH MUCH OF THE WINTER.

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

SUMMARY OF IMPACTS...

* THE LONG TERM DRYNESS HAS REDUCED FORAGE, WITH MOST PASTURE
  CONDITIONS RATED BETWEEN POOR AND GOOD.
* STOCK PONDS AND DUGOUTS ARE LOW, WHICH CONTINUES TO LIMIT WATER
  FOR CATTLE AND OTHER ANIMALS.
* DRY FUELS HAVE CONTRIBUTED TO SEVERAL WILDFIRES THIS YEAR.

CLIMATE SUMMARY...

TEMPERATURES FOR MOST OF 2016 HAVE BEEN ABOVE AVERAGE. RAINFALL HAS
VARIED WITH MAY AND JUNE BEING EXTREMELY DRY, SPOTTY AREA OF BELOW
AND ABOVE AVERAGE RAINFALL IN JULY, AVERAGE TO ABOVE AVERAGE AMOUNTS
IN AUGUST, NEAR AVERAGE IN SEPTEMBER, AND BELOW AVERAGE
PRECIPITATION IN OCTOBER AND NOVEMBER.

PRECIPITATION/TEMPERATURE OUTLOOK...

SEA SURFACE TEMPERATURE (SST) ANOMALIES ACROSS THE EQUATORIAL
PACIFIC OCEAN HAVE BEEN BELOW AVERAGE, INDICATING WEAK LA NINA
CONDITIONS. THE EL NINO/SOUTHERN OSCILLATION (ENSO) SUGGESTS LA NINA
WILL CONTINUE THROUGH FEBRUARY. HOWEVER, IT APPEARS LA NINA WILL BE
SHORT-LIVED, WITH ENSO-NEUTRAL CONDITIONS FAVORED FOR THE SPRING.

THE OUTLOOK FOR DECEMBER INDICATES THERE IS A GREATER CHANCE FOR
BELOW AVERAGE TEMPERATURES AND ABOVE AVERAGE PRECIPITATION.

THE WINTER OUTLOOK FOR DECEMBER THROUGH FEBRUARY INDICATES A GREATER
CHANCE FOR BELOW AVERAGE TEMPERATURES AND SLIGHTLY ABOVE AVERAGE
PRECIPITATION. FOR DECEMBER THROUGH FEBRUARY, AVERAGE HIGH
TEMPERATURES ARE IN THE MID 30S WITH AVERAGE LOW TEMPERATURES IN THE
MID TEENS. AVERAGE PRECIPITATION DURING THIS TIME IS AROUND AN INCH
ON THE PLAINS WITH TWO TO THREE INCHES IN THE BLACK HILLS AND BEAR
LODGE MOUNTAINS.

NEXT ISSUANCE...

THE NEXT DROUGHT STATEMENT WILL BE ISSUED IN JANUARY, UNLESS
CONDITIONS CHANGE SOONER.
