...DROUGHT CONDITIONS GENERALLY HOLDING STEADY...

SYNOPSIS...

Snowfall events so far this winter have generally been on the light
side with very little precipitation. Therefore, drought conditions
have held steady over the past month and a half. Typically, drought
conditions do not change very much during the winter months unless
significant precipitation occurs. Snow pack across the region is
minimal as well due to the lack of significant snow events.

D2 (Severe) drought counties: Western Corson

D1 (Moderate) drought counties: Eastern Corson, Dewey, Stanley,
Jones, Campbell, Walworth, Potter, Sully, Hughes, northwest Lyman,
McPherson, Edmunds, northwest Faulk, western Brown.

D0 (Abnormally Dry) counties: Eastern Hughes, Lyman, Hyde, Hand,
Buffalo, Faulk, eastern Brown, Spink, Clark, Marshall, Day, western
Codington, northwest Hamlin.

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 reprt, the month of December 2017 had topsoil moisture
ratings of 53 percent short or very short. This is a 12 percent
increase from late November. Subsoil moisture was rated 56 percent
short or very short. This is a 5 percent increase from conditions
seen in late November.

AGRICULTURAL IMPACTS:
The latest Crop Progress and Condition report rated winter wheat
conditions at 36 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 before
freezing.

FIRE DANGER IMPACTS:
Lack of snow cover during much of December led to some days of
moderate to high fire danger whenever humidity was low and winds were
strong. Grass fires were reported well into December with Fire
Weather Planning forecasts being issued throughout the month from
National Weather Service offices. This activity ran much longer than
normal due to the continued dry conditions and above normal
temperatures which persisted well into December.

CLIMATE SUMMARY...

The month of December gave below normal precipitation for most areas,
along with above normal temperatures. Around Christmas, the pattern
changed to favor colder than normal temperatures, which have
generally persisted into January. Snowfall totals for the season
continue to run below average.

PRECIPITATION/TEMPERATURE OUTLOOK...

The latest one-month outlook from the Climate Prediction center calls
for higher probabilities for below normal temperatures. As for
precipitation, there is an increased probability for below normal
across eastern South Dakota into west central Minnesota. The latest
three-month outlook shows a higher probability for below normal
temperatures. For precipitation, much of the area shows "equal
chances" for above or below normal, although there is a slightly
higher probability for above average across western and far northern
South Dakota.

HYDROLOGIC SUMMARY AND OUTLOOK...

The latest Probabilistic Hydrologic Outlook from the National Weather
Service in Aberdeen shows very low chances for many of the rivers
across the County Warning Area reaching flood stage in the next 90
days. Although, the Big Sioux River in the Watertown area has a 25
percent to 50 percent chance of reaching minor flood stage in the
next 90 days.

NEXT ISSUANCE DATE...

This product will be updated around February 11th or sooner if
necessary in response to significant changes in conditions.
