...DROUGHT IMPROVEMENTS NOTED FOR SOME...ALTHOUGH LONGER TERM
DRYNESS PERSISTS...

SYNOPSIS...

Episodes of rainfall have continued over the past one to two weeks
across portions of northeast South Dakota. There has been enough
rainfall on the larger scale to rid the area of D2 (severe) drought
conditions. Impacts have begun to decrease as well, and are becoming
more localized in nature. Longer term precipitation deficits still
remain, thus keeping moderate (D1) drought conditions in place.

D1 (Moderate) drought counties: Brown, extreme southeastern
McPherson, eastern Edmunds, northeastern Faulk, northern Spink,
northern Clark, Day, extreme southwestern Marshall.

D0 (Abnormally Dry) counties: eastern McPherson, central Edmunds,
Faulk, southern Spink, southern Clark, western Hamlin, western
Codington, Marshall, Roberts, western Grant, western Big Stone,
western Traverse.

SUMMARY OF IMPACTS...

STATE AND LOCAL ACTIONS:
None known.

SOIL MOISTURE CONDITIONS:
According to the latest release of the South Dakota Crop Progress and
Condition report for the week ending July 8th, topsoil moisture
supplies was rated 18 percent short or very short. Subsoil moisture
supplies was rated 23 percent short or very short. This latest
subsoil moisture rating is a 3 percent improvement from a week ago.

AGRICULTURAL IMPACTS:
The latest Crop Progress and Condition report for the state of South
Dakota showed corn condition at 6 percent poor or very poor. Soybeans
were rated 8 percent poor or very poor. Winter wheat conditions show
13 percent poor or very poor. Spring wheat was rated 14 percent poor
or very poor. Oats was 4 percent poor or very poor, while sorghum was
rated 2 percent poor or very poor. Pasture and range condition was
rated 10 percent poor or very poor.

RIVER AND STREAMFLOW CONDITIONS:
Current 7-day average streamflows across the area are normal to above
normal.

FIRE DANGER IMPACTS:
Fire danger has been low across most of the area recently, due to
natural and rain-induced green-up. Fire activity has been fairly low
even in areas of D1 drought. Overall, fire danger will likely remain
low unless conditions begin to dry out and heat up across the area
over the next month.

CLIMATE SUMMARY...

The month of June saw below normal precipitation across northeast
South Dakota. An area from Spink county northward through Day and
Marshall counties only saw 50 to 70 percent of its normal rainfall.
Across central South Dakota, precipitation was generally above normal
for the month of June. As for temperatures, the entire region was
above normal. Although, these above normal temperatures were
maximized in the James River valley, where there was a pocket that
averaged 6 to 7 degrees above normal.

PRECIPITATION/TEMPERATURE OUTLOOK...

The latest 8 to 14 day outlook from the Climate Prediction Center
calls for near normal temperatures over western and central South
Dakota, with in increased probability for below normal temperatures
over eastern South Dakota and west central Minnesota. There is an
increased probability for below normal precipitation. The latest
one-month outlook shows an increased probability for above normal
temperatures, with equal chances for above or below normal
precipitation.

HYDROLOGIC SUMMARY AND OUTLOOK...

According to the latest Probabilistic Hydroligic Outlook issued by
the National Weather Service in Aberdeen, the James River across
Brown and Spink counties has only roughly a 10 percent chance of
reaching flood stage in the next 90 days.

NEXT ISSUANCE DATE...

Since no areas within the Aberdeen County Warning Area have D2
(severe) drought conditions, this will be the last Drought
Information Statement until conditions reach D2 again in the future.
