...DROUGHT CONDITIONS EXPANDING AND WORSENING ACROSS CENTRAL AND
NORTHEAST SOUTH DAKOTA...

SYNOPSIS...

Overall dryness continues to affect the region, especially from
central and into northeast South Dakota. Drought conditions have
expanded and continue to worsen across the area due to several weeks
of below normal rainfall. More recently, persistent hot temperatures
and low humidity have only exacerbated the situation.

The United States Drought Monitor has classified portions of north
central and northeast South Dakota in Severe (D2) drought, including
the counties of: Corson, northern Dewey, Campbell, Walworth,
McPherson, Edmunds, Faulk, western Brown, and northwest Spink.

Moderate (D1) drought conditions include the counties of: southern
Dewey, Stanley, northern Jones, northern Lyman, Potter, Sully,
Hughes, Buffalo, Hand, Hyde, eastern Brown, eastern Spink, Marshall,
Day, northern Clark, and western Roberts.

Abnormally dry (D0) conditions extend south to near the Nebraska
border and east towards the Watertown area.

SUMMARY OF IMPACTS...

STATE AND LOCAL ACTIONS:
Several counties have enacted burn bans over the past couple weeks
due to the drying conditions and increasing fire danger. A handful of
counties have either begun or completed the process of issuing
Drought Declarations.

SOIL MOISTURE CONDITIONS:
Calculated soil moisture anomalies from June 7th show deficits across
north central South Dakota ranging from 60mm to 100mm. Deficits
across the rest of South Dakota (except for the southeast) range from
20mm to 60mm. The June 5th USDA South Dakota Crop Progress and
Condition report indicate topsoil moisture supplies rated 54 percent
short or very short. Subsoil moisture was rated 52 percent short or
very short.

AGRICULTURAL IMPACTS:
There are many reports of winter wheat being cut for hay instead of
harvesting for grain - mainly central and northern parts of South
Dakota. Cattle may have to graze on spring wheat. Cattle are also
being sold, both yearlings and cow/calf pairs. This is happening in
mainly central and northern areas as well, where D2 drought
conditions exist. Cattle are now feeding on dry lots in many areas,
instead of out on pastures, due to short grass. This brings the risk
of possible dust pneumonia to calves especially. Alfalfa is not even
being cut once in central South Dakota.

The latest South Dakota Crop Progress and Condition report indicates
Alfalfa hay condition rated 65 percent poor or very poor. Pasture and
range condition rated 40 percent poor or very poor. Stock water
supplies rated 26 percent short or very short.

RIVER AND STREAM FLOW CONDITIONS:
Seven-day average stream flow compared to historical stream flow is
below normal at the Bad River near Fort Pierre. Below normal
conditions are also found at the Big Sioux River at Watertown and the
Little Minnesota River near Peever.

FIRE DANGER IMPACTS:
Persistent dry conditions and recent hot temperatures with low
humidity have increased fire danger across the region. After low to
sometimes moderate fire danger during spring green-up, days of high
fire danger are likely during dry and windy periods.

CLIMATE SUMMARY...

Much of central South Dakota, as well as portions of northeast South
Dakota have only seen 25 percent to 50 percent of normal
precipitation in the past 90 days. Across the D1 and D2 drought
areas, precipitation since the start of the year is running roughly
3.50 to 4.50 inches below normal.

PRECIPITATION/TEMPERATURE OUTLOOK...

The 8 to 14 day outlook issued on June 7th from the Climate
Prediction Center forecasts below normal temperatures across northern
and eastern South Dakota, with below normal precipitation forecast
west of Interstate 29. The latest 3 to 4 week outlook calls for equal
chances for above or below normal temperatures and precipitation.

HYDROLOGIC SUMMARY AND OUTLOOK...

The latest Probabilistic Hydrologic Outlook from the National Weather
Service in Aberdeen shows a less than 25 percent chance of rivers
reaching minor flood state across the D1 and D2 drought areas during
the next 90 days.

NEXT ISSUANCE DATE...

This product will be updated around July 1st or sooner if necessary
in response to significant changes in conditions.
