...IMPROVEMENTS NOTED IN DROUGHT CONDITIONS ACROSS CENTRAL SOUTH
DAKOTA...

SYNOPSIS...

A changing weather pattern in August has brought cooler conditions
to the region, along with more frequent episodes of showers and
thunderstorms. Several rounds of heavy rain have also been observed
over the past three weeks, which have affected portions of central
and northeast South Dakota. Although much of the damage has already
been done as far as some crops are concerned, the precipitation
totals have been easing drought conditions across the region over the
past few weeks. Most of north central South Dakota has been erased
from D3 (Extreme) drought conditions.

D3 (Extreme) drought counties: Extreme western Corson, extreme
northwest McPherson.

D2 (Severe) drought counties: Western Corson, western Dewey, Stanley,
Jones, Lyman, Hughes, Sully, Potter, Walworth, Campbell, McPherson,
western Edmunds, extreme western Faulk, Hyde, southwest Hand,
Buffalo.

D1 (Moderate) drought counties: Eastern Corson, eastern Dewey,
extreme southern Lyman, Brown, eastern Edmunds, Faulk, Hand, western
Spink, southern Marshall, northern Day.

D0 (Abnormally Dry) counties: Eastern Spink, Clark, Hamlin,
Codington, Deuel, Day, Marshall, northwest Roberts.

SUMMARY OF IMPACTS...

STATE AND LOCAL ACTIONS:
Several counties have lifted their burn bans, including, but not
limited to Campbell, Day, Faulk, Marshall, McPherson, Walworth, and
Brown. More counties are expected to lift burn bans in the near
future.

SOIL MOISTURE CONDITIONS:
The August 14th USDA South Dakota Crop Progress and Condition report
indicates topsoil moisture is 66 percent short or very short, which
is a 19 percent improvement from nearly a month ago. Subsoil moisture
is rated 75 percent short or very short. This is only a 4 percent
improvement from about a month ago.

AGRICULTURAL IMPACTS:
During the end of July, an increase in the number of sick or dead
livestock was noted due to nitrate poisoning. Resources have been
made available for nitrate testing as well as Total Dissolved Solids.

The latest Crop Progress and Condition report showed barley was rated
82 percent poor or very poor. Corn condition was rated 31 percent
poor or very poor. Soybeans were 22 percent poor or very poor.
Alfalfa ratings show 79 percent poor or very poor. As for pasture and
range conditions, they were rated at 63 percent poor or very poor.
Stock water supplies were rated 56 percent short or very short.

RIVER AND STREAM FLOW CONDITIONS:
Seven-day average stream flows compared to historical stream flow is
generally normal to above normal across the region due to recent
moderate and heavy rainfall over the past couple weeks.

FIRE DANGER IMPACTS:
As mentioned previously, several counties have lifted burn bans due
to improving conditions. Less days of HIGH to VERY HIGH fire danger
have been noted over the past few weeks, due to higher frequencies of
cooler days and precipitation. Percent green has been increasing in
spots as well, especially for northeast South Dakota.

CLIMATE SUMMARY...

Mobridge has seen 5.48 inches of precipitation in August, which is
4.28 inches above normal. Since June 1st, Mobridge is now 2.89 inches
above normal. And now, they are only 0.60 inches below normal for the
calendar year. In fact, much of north central South Dakota is running
200 to 400 percent of normal over the past 30 days, which has helped
erase the D3 drought conditions. Above normal precipitation has been
noted across the rest of the area as well. As for temperatures, thus
far in August most locations are generally 4 to 7 degrees below
normal.

PRECIPITATION/TEMPERATURE OUTLOOK...

The 8 to 14 day outlook issued on August 17th from the Climate
Prediction Center is calling for near normal temperatures and
precipitation. The one-month outlook calls for equal chances for
above or below normal temperatures and precipitation. The three-month
outlook shows a higher probability for above normal temperatures,
with equal chances for above or below normal precipitation.

HYDROLOGIC SUMMARY AND OUTLOOK...

The latest Probabilistic Hydrologic Outlook from the National Weather
Service in Aberdeen shows low chances for any of the rivers across
the County Warning Area reaching flood stage in the next 90 days.

NEXT ISSUANCE DATE...

This product will be updated around September 18th or sooner if
necessary in response to significant changes in conditions.
