Drought Information Statement
National Weather Service Rapid City SD
615 AM MDT Thu May 17 2018

...Drought Conditions Continue Across the Northern High Plains...

SYNOPSIS... Short-term moisture has helped to ease drought concerns,
but impacts remain due to longer term shortfalls.

The latest U.S. Drought Monitor depicts:

*  Moderate (D1) drought conditions covered most of Perkins, most of
   Meade, Ziebach, western Haakon, eastern Pennington, and
   northeastern Harding Counties.
*  Abnormally dry (D0) conditions covered the rest of Perkins,
   Meade, Haakon, eastern Harding Counties, as well as the rest of
   Pennington, southeastern Butte, eastern half of Custer, far
   northern Oglala Lakota, Jackson, and northwestern Mellette

SUMMARY OF IMPACTS... Long-term drought impacts continue to be
reported by producers, including low stock ponds and dugouts.

CLIMATE SUMMARY... In April, temperatures were well below average
and precipitation was slightly below average. So far in May,
temperatures have been slightly above average and precipitation
below average.

PRECIPITATION/TEMPERATURE OUTLOOK... Sea surface temperatures in the
tropical Pacific Ocean have been warming, indicating a trend toward
neutral El Nino Southern Oscillation (ENSO) conditions. For the
Northern Plains, this pattern typically favors a warmer and drier
pattern by early summer.

The outlook for May calls for a greater chance for above average
temperatures and near to above average precipitation.

The three month outlook for June, July, and August calls for equal
chances for above, below and near normal temperatures and

HYDROLOGIC SUMMARY AND OUTLOOK... According to the U.S. Geological
Survey 28-day average streamflow compared to historical streamflow
for the day of the year indicates normal conditions across much of
the area.

NEXT ISSUANCE... The next drought statement will be issued in the
middle of June 2018, unless conditions change sooner.


ACKNOWLEDGMENTS... The drought monitor is a multi-agency effort
involving NOAA`s National Weather Service and the National Centers
for Environmental Information, United States Department of
Agriculture (USDA), State and Regional Climate Centers, and the
National Drought Mitigation Center at the University of Nebraska-
Lincoln. Information for this statement has been gathered from the
NWS and Federal Aviation Administration observing sites, State
Cooperative Extension Services, United States Department of
Agriculture, Bureau of Reclamation, and the United States Geological
