...SEVERE DROUGHT CONDITIONS ONCE AGAIN FOR A SMALL AREA OF NORTHEAST
SOUTH DAKOTA...

SYNOPSIS...

August has been very dry across northeast and north central South
Dakota, which has led to worsening drought conditions. Improvements
were noted by mid July as episodes of rainfall moved over northeast
South Dakota. Over the past few weeks though, dryness has once again
taken over, with hot temperatures as well. A small area of severe
drought is noted over northeast South Dakota, where longer term
dryness is a problem.

D2 (Severe) drought counties: Southwest Brown, northwest Spink,
northeast Faulk, eastern Edmunds.

D1 (Moderate) drought counties: Southern Brown, Edmunds, southeast
McPherson, eastern Walworth, eastern Potter, Faulk, northern Hand,
northern Hyde, Spink, northwest Clark, southwest Day.

D0 (Abnormally Dry) counties: Much of central and northeast South
Dakota.

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 August 12th, topsoil moisture
supplies was rated 38 percent short or very short. This is 20 percent
higher compared to conditions in early July. Subsoil moisture
supplies was rated 39 percent short or very short. This is 26 percent
higher than early July.

AGRICULTURAL IMPACTS:
The latest Crop Progress and Condition report for the state of South
Dakota showed corn condition 7 percent poor or very poor. Soybeans
were rated 9 percent poor or very poor. Sorghum was rated 3 percent
poor or very poor. Pasture and range conditions were rated 16 percent
poor or very poor.

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

FIRE DANGER IMPACTS:
Fire danger has been increasing over the past week or two as dry and
hot temperatures have been the story for the first half of August.
Fuels are drying out and have actually reached a critical state
across much of central South Dakota. During times of strong winds and
low humidity, high to very high fire danger has been noted. A few
grass fires have also occurred across the region.

CLIMATE SUMMARY...

So far for the month of August, Mobridge has only received a trace of
rainfall. Aberdeen has only received 0.06 inches of rain and Sisseton
only 0.09. Over the past 30 days, precipitation has only been 25 to
75 percent of normal over the D1 and D2 drought area. Longer term
precipitation deficits remain in this area. Going back 120 days, the
D2 drought area is about 4 to 6 inches below normal.

PRECIPITATION/TEMPERATURE OUTLOOK...

The latest 8 to 14 day outlook from the Climate Prediction Center
calls for an increased probability for above normal temperatures and
precipitation. The latest one-month outlook calls for equal chances
for above or below normal temperatures and precipitation.

HYDROLOGIC SUMMARY AND OUTLOOK...

According to the latest Probabilistic Hydrologic Outlook issued by
the National Weather Service in Aberdeen, there is generally a 20
percent or less chance for any of the rivers in the forecast area to
reach flood stage.

NEXT ISSUANCE DATE...

This product will be updated around September 17th, or sooner if
necessary, in response to significant changes in conditions.
