...DROUGHT CONDITIONS WORSEN ACROSS NORTH CENTRAL SOUTH DAKOTA...

.SYNOPSIS:

.Drought Intensity and Extent: According to the April 1st release of
the U.S. Drought Monitor, drought conditions across north central
South dakota have worsened into the Extreme (D3) category. Counties
in Extreme (D3) drought include Corson, northwestern Dewey, western
Campbell, and northwestern Walworth. Severe (D2) drought and Moderate
(D1) drought areas have remained relatively unchanged over the past
couple weeks. Counties in Severe (D2) drought include Stanley,
Potter, Sully, eastern Walworth, eastern Campbell, McPherson,
Edmunds, western Faulk, and northern Hyde. Moderate (D1) counties
include Jones, Lyman, Hughes, southern Hyde, Hand, eastern Faulk,
Brown, Marshall, northern Day, western Spink, Buffalo, Big Stone, and
Traverse. Abnormally dry (D0) conditions covered east central South
Dakota.

.Precipitation: Northern portions of South Dakota, especially the
north central region, continues to remain dry. Parts of Corson
county, which is included in the Extreme (D3) drought, have only
received 5 percent or less of normal precipitation during the month
of March. A larger portion of north central South Dakota has only
received 5 to 25 percent of normal precipitation in March. Looking
back at longer timescales of 60 and 90 days, much of north central
South Dakota still remains at 5 to 25 percent of normal. Since
October 1st, which is the start of the water year, most of northern
South Dakota is at 25 to 50 percent of normal precipitation. In terms
of inches, much of northern South Dakota is 2.25 to over 3 inches
below normal.

.Temperature: During the month of March, temperatures were anywhere
from 6 to as much as 10+ degrees above normal across the region.

.Hydrologic conditions: 7-day average streamflows compared to
historical streamflows for April 2nd reflect below normal conditions
across parts of northeast South Dakota. The Big Sioux River near
Florence is at the 23rd percentile, while the Little Minnesota River
near Peever is at the 15th percentile.

.SUMMARY OF IMPACTS:

.Agricultural Impacts: According to the March 29th release of South
Dakota crop conditions from the National Agricultural Statistics
Service, topsoil moisture supplies rated 22 percent very short and
44 percent short. Subsoil moisture supplies rated 20 percent very
short and 55 percent short. Most of these numbers are slight
increases from conditions one month ago, indicating continued drying
soils. Winter wheat condition rated 3 percent very poor and 18
percent poor.

.Hydrologic Impacts: Stock ponds and dugouts are dry or contain poor
water quality over parts of western and central South Dakota.

.Fire Hazards: Over the past two weeks, the Grassland Fire Danger has
reached VERY HIGH or even EXTREME levels, with several grass fires
reported.

.DROUGHT MITIGATION ACTIONS: None reported.

.LOCAL DROUGHT OUTLOOK: The latest one month outlook for April,
issued on March 31st from the Climate Prediction Center, shows
probabilities that favor above normal temperatures across the
northern plains. As for precipitation, probabilities show a nudge
towards above average for northeast South Dakota and west central
Minnesota, while the rest of the region has "equal chances" for
above or below normal precipitation. The latest seasonal drought
outlook calls for drought persistence across the area.

.NEXT ISSUANCE DATE: This product will be updated around April 30th,
or sooner if drought conditions change significantly.
