...SNOW DROUGHT CONTINUES FOR MANY AREAS...

SYNOPSIS...

Generally dry conditions have continued through the first half of the
winter as heavy snow events have been non-existent over the region.
Northeast South Dakota and west central Minnesota have been
exceptionally dry so far this winter, with minimal snowfall compared
to normal. Snow pack over this area is also minimal. A serious of
light snow events across central South Dakota over the past two weeks
has produced a few inches of snow cover, but moisture content has
been lacking. Because of all this, drought conditions have worsened
over northeast areas, whereas conditions have held steady over
central South Dakota.

D2 (Severe) drought counties: Western Corson.

D1 (Moderate) drought counties: Eastern Corson, Dewey, Stanley,
Jones, Campbell, Walworth, Potter, Sully, Hughes, northwest Lyman,
McPherson, Edmunds, Faulk, Brown, northern Spink, Marshall, Day,
northern Clark, Roberts, northern Grant, northern Codington, Big
Stone, Traverse.

D0 (Abnormally Dry) counties: Lyman, Hyde, Hand, southern Spink,
southern Clark, southern Codington, northwest Hamlin, southern Grant,
northern Deuel.

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, the month of January had topsoil moisture ratings
of 64 percent short or very short. This is an 11 percent increase
from December, and a 23 percent increase since November. Subsoil
moisture was rated 62 percent short or very short. This is a 6
percent increase from December, and an 11 percent increase since
November. These numbers continue to verify the continuing/worsening
drought conditions across the region.

AGRICULTURAL IMPACTS:
The latest Crop Progress and Condition report rated winter wheat
conditions at 21 percent poor or very poor.

RIVER AND STREAM FLOW CONDITIONS:
Rivers and streams across the region are frozen for the winter
season, but most of them were at near to below normal levels prior to
freezing.

FIRE DANGER IMPACTS:
A snow cover has developed over much of the region over the past few
weeks, therefore greatly diminishing fire danger. Although, northeast
South Dakota and west central Minnesota have minimal snow cover. If
melting occurs over the next few weeks with a continued lack of snow,
fire danger impacts may crop up sooner than usual.

CLIMATE SUMMARY...

Precipitation for the month of January was below normal across the
region, while temperatures were mostly above normal. Thus far in
February, precipitation is running below normal across northeast
South Dakota and west central Minnesota. Over central South Dakota,
precipitation is actually a bit above normal thus far, due to the
series of light snow events over the past couple weeks. Temperatures
have been well below normal during the first half of February.

PRECIPITATION/TEMPERATURE OUTLOOK...

The latest one-month outlook from the Climate Prediction Center shows
a higher probability for below normal temperatures and above normal
precipitation. The latest three-month outlook shows a higher
probability for below normal temperatures. As for precipitation,
higher probabilities for above normal precipitation show up over
northwest South Dakota.

HYDROLOGIC SUMMARY AND OUTLOOK...

According to the latest Probabilistic Hydrologic Outlook issued by
the National Weather Service in Aberdeen, the Big Sioux River in the
Watertown area has between a 25 and 50 percent chance of exceeding
flood stage in the next 90 days. All the other rivers and streams
across the area show very low chances (less than 5 percent) of
reaching flood stage in the next 90 days.

NEXT ISSUANCE DATE...

This product will be updated around March 13th or sooner, if
necessary, in response to significant changes in conditions.
