DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE RAPID CITY SD
715 AM MDT Thu May 4 2017

...Drought Conditions Improve Across Western South Dakota and
Northeastern Wyoming...

SYNOPSIS...

Recent rains have helped ease drought conditions across parts of
western South Dakota and northeastern Wyoming. The current drought
conditions reflect long-term moisture deficits dating back to last
summer and include lower than average streamflow in the Black Hills
due to snow melting earlier this spring.

At the beginning of May, Moderate (D1) drought conditions only
covered two small areas in northeastern Wyoming. One area was in
Crook County, southwest of Sundance; the other area was in
northeastern Weston County around Newcastle.

Abnormally dry (D0) conditions covered the rest of Crook and Weston
Counties as well as eastern Campbell and most of Lawrence Counties.

SUMMARY OF IMPACTS...

* Soil moisture is beginning to recover in the top layers of the
  ground due to the recent precipitation.
* Stock ponds and dugouts are still low, which continues to limit
  water for cattle and other animals.

CLIMATE SUMMARY...

Temperatures in April were near average and precipitation was
mainly above average.

PRECIPITATION/TEMPERATURE OUTLOOK...

Sea surface temperatures in the tropical Pacific Ocean are above
average, indicating a possible developing El Nino. The outlook for
the spring and summer is for a continuation of the relatively warm
waters, with odds favoring El Nino conditions by the summer into
fall. If El Nino develops this summer, that would tilt the odds
toward increased chances of above average rainfall, with
temperatures near average.

The three month outlook for May, June, and July calls for odds
tilted toward above-average precipitation and above average
temperatures.

HYDROLOGIC SUMMARY AND OUTLOOK...

According to the Bureau of Reclamation, reservoir levels are
slightly above average for this time of the year, with the exception
of Shadehill Reservoir, which is slightly below average. Streamflows
according to the U.S. Geological Survey have been around normal.
Links to hydrologic data from the U.S. Geological Survey and Bureau
of Reclamation can be found below.

NEXT ISSUANCE...

The next drought statement will be issued in June unless conditions
change sooner.
