...DROUGHT CONDITIONS EASE FOR SOME...WHILE CENTRAL SOUTH DAKOTA
REMAINS DRY...

SYNOPSIS...

Periodic rainfall events over the past month have allowed drought
conditions to ease a bit over portions of the James River valley into
south central South Dakota. Although, overall dryness has continued
over north central South Dakota, where moderate to severe drought
conditions persist.

D2 (Severe) drought counties: Western Dewey, western and northern
Corson, western Campbell.

D1 (Moderate) drought counties: Southeastern Corson, eastern
Campbell, eastern Dewey, western Walworth, western Edmunds, Potter,
Sully, Hughes, Stanley, Jones, northwestern Lyman.

D0 (Abnormally Dry) counties: Eastern Walworth, Lyman, McPherson,
eastern Edmunds, Faulk, Hyde, Hand, Buffalo, Brown, Spink,
southwestern Marshall, western Day.

SUMMARY OF IMPACTS...

STATE AND LOCAL ACTIONS:
The South Dakota Game, Fish and Parks has completed the annual
pheasant brood survey and the results show a significant decrease in
the statewide pheasants-per-mile (PPM) index from 2016. The 2017
statewide PPM index is 1.68, down from last year`s index of 3.05.
During the very severe drought conditions, pheasant nesting success
and chick survival was reduced due to less cover and a reduction in
insects for chicks to feed on.

SOIL MOISTURE CONDITIONS:
The October 23rd release of the South Dakota Crop Progress and
Condition report indicates topsoil moisture is rated 35 percent short
or very short. This is a 13 percent improvement from about a month
ago. Subsoil moisture is 49 percent short or very short. This is a 14
percent improvement from a month ago.

AGRICULTURAL IMPACTS:
The latest Crop Progress and Condition report rated winter wheat at
46 percent poor or very poor. Sorghum condition is rated 33 percent
poor or very poor. Pasture and range condition is rated 52 percent
poor or very poor, while stock water supplies are rated 46 percent
short or very short.

RIVER AND STREAM FLOW CONDITIONS:
As of October 22nd, 7-day Average Streamflow was below normal for the
Grand River at Little Eagle. Across northeast South Dakota and west
central Minnesota, conditions are average to above average.

FIRE DANGER IMPACTS:
The lack of vegetation greenness across the region due to dryness and
the changing of the seasons has led to periods of high to very high
fire danger whenever strong winds combine with low humidity. Central
South Dakota continues to see a higher frequency of days with high to
very high fire danger.

CLIMATE SUMMARY...

Over the past 60 days, the largest precipitation departures are
showing up over north central South Dakota where they are about 50 to
75 percent of normal. This is the area of Corson and Dewey counties
where they are still seeing D2 (Severe) drought conditions.
Elsewhere, deficits are a bit lower, with a surplus of precipitation
over northeast South Dakota and west central Minnesota.

PRECIPITATION/TEMPERATURE OUTLOOK...

The 8 to 14 day outlook issued on October 23rd from the Climate
Prediction Center calls for increased probabilities for below normal
temperatures and above normal precipitation. The latest one-month and
three-month outlooks all show equal chances for above or below normal
temperatures, as well as above or below normal precipitation.

HYDROLOGIC SUMMARY AND OUTLOOK...

The latest Probabilistic Hydrologic Outlook from the National Weather
Service in Aberdeen shows very 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 November 23rd or sooner if
necessary in response to significant changes in conditions.
