...DROUGHT CONDITIONS HOLD FAIRLY STEADY OVER THE PAST MONTH...

SYNOPSIS...

Periodic episodes of precipitation across the region have prevented
widespread worsening of drought conditions. Although, there have
been stretches of dryness and above normal temperatures over
portions of the area, keeping moderate or severe drought conditions
in place. Much of central South Dakota is still feeling the effects
of long term dryness which started back in Spring.

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

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

D0 (Abnormally Dry) counties: Eastern Spink, northern Clark, eastern
Day, Marshall, western Roberts.

SUMMARY OF IMPACTS...

STATE AND LOCAL ACTIONS:
Various counties still have burn bans in place due to the continued
dryness. Although, a handful of counties have lifted their bans over
the past few weeks due to improving conditions.

SOIL MOISTURE CONDITIONS:
The September 18th USDA South Dakota Crop Progress and Condition
report indicates topsoil moisture is 48 percent short or very short.
This is an 18 percent improvement from about a month ago. Subsoil
moisture is 63 percent short or very short. This is a 12 percent
improvement from nearly a month ago.

AGRICULTURAL IMPACTS:
The latest Crop Progress and Condition report rated corn at 28
percent poor or very poor. Alfalfa was rated 63 percent poor or very
poor. Soybean condition shows ratings of 19 percent poor or very
poor. Sorghum is rated 29 percent poor or very poor. The report also
showed sunflowers rated 29 percent poor or very poor. Pasture and
range conditions are 58 percent poor or very poor while stock water
supplies are 56 percent short or very short.

RIVER AND STREAM FLOW CONDITIONS:
As of September 20th, 7-day Average Streamflow was below normal for
the Grand River at Little Eagle and for the Big Sioux River near
Castlewood.

FIRE DANGER IMPACTS:
The lack of vegetation greenness across central South Dakota
continues to bring episodes of high to very high fire danger whenever
strong winds combine with low relative humidity.

CLIMATE SUMMARY...

Precipitation totals over the last 30 days ending September 20th are
below normal across most of the forecast area. The largest departures
from normal are showing up across far northeast South Dakota and also
over the Pierre area.

PRECIPITATION/TEMPERATURE OUTLOOK...

The 8 to 14 day outlook issued on September 20th from the Climate
Prediction Center calls for near normal temperatures and below normal
precipitation. The one-month outlook issued on September 21st shows
a higher probability for above normal temperatures over the entire
forecast area, while the precipitation outlook favors below normal
for eastern South Dakota into west central Minnesota. The latest
3-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 October 21st or sooner if
necessary in response to significant changes in conditions.
