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


After a dry and hot early June, a storm system finally tracked
across the northern plains this past week. This storm lowered
temperatures a little bit and finally brought some much needed rain
to the area. For the most part, the rains were not great enough to
make sizable improvements to the drought conditions. After another
dry and warm week, drought conditions have continued to worsen. The
current drought conditions not only reflect the recent weather
conditions, but also include the lower than average streamflows, as
well as the long-term moisture deficits dating back to last summer.

Severe (D2) drought conditions were expanded to northeastern
Perkins, portions of Ziebach, northern Haakon, and northeastern
Pennington Counties in South Dakota.

Moderate (D1) drought conditions covered the rest of Perkins,
Ziebach, and Haakon Counties as well as northeastern Harding,
southeastern Butte, Meade, central and eastern Pennington, and far
northern Tripp Counties.

Abnormally dry (D0) conditions covered most of Crook, and Weston
Counties in northeastern Wyoming. In South Dakota, abnormally dry
(D0) conditions covered Lawrence, Custer, northern Fall River, far
northern Oglala Lakota, Jackson, Mellette, Todd, and the rest of
Harding, Butte, Pennington, and Tripp Counties.

On June 16, 2017, Governor Dennis Daugaard declared a statewide
drought emergency for South Dakota as crops and livestock continued
to suffer without sufficient rain. Transport restrictions have been
eased, allowing the movement of oversized loads of hay and feed with
proper signage and reflectors. Landowners adjacent to highways may
mow and bale hay along state highways.


Drought impacts continue to be reported by agricultural producers.
Many impacts are related to crop failures in winter and spring
wheat. Other substantial impacts include cattle sales owing to feed
shortages and poor growth in pastures and hay lands. Sale barns in
the central and northern areas of South Dakota have had many more
cattle for sale than is typical for this time of the year. Sales are
including cow/calf pairs, which indicates culling of herds. Corn and
soybean fields have exhibited slow growth, and there have been some
areas with uneven emergence compared to normal years. Pre-emergence
herbicides were less effective to control weeds with the dry
conditions. "Shutoff orders" have begun for irrigation water from
the Little Missouri River in Harding County. Soil moisture is
quickly drying out. The latest USDA South Dakota Crop Progress and
Condition Report indicated that topsoil moisture supplies rated as
55 percent very short or short and subsoil moisture supplies rated
as 55 percent short or very short.


May temperatures were around average and precipitation was below
average. So far in June, it has been hot and dry with temperatures
averaging 4 to 8 degrees above average and precipitation about an
inch below average.


Sea surface temperatures in the tropical Pacific Ocean are slightly
above average, indicating neutral El Nino Southern Oscillation
(ENSO) conditions. The outlook for the summer and fall is for a
continuation of the ENSO-neutral conditions. For the northern
plains, this means there are equal chances for above, below, and
near-average temperatures and precipitation.

The outlook for July calls for a greater chance of above average
temperatures with equal chances for above, below, and near-average

The three-month outlook for July, August, and September calls for
increased odds toward above-average precipitation and temperatures.


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


The next drought statement will be issued around June 29.



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 Survey.
