DROUGHT INFORMATION STATEMENT

...A Small Area of Moderate Drought Continues across Northeast
Iowa...

SYNOPSIS...

Since mid-June, precipitation deficits of 4 to 6 inches have
developed across Allamakee and Winneshiek counties in northeast Iowa
and Fillmore and Houston counties in southeast Minnesota.  Due to
this, the U.S. Drought Monitor added a small area of moderate
drought (D1) with its August 15th release and it continued it with
their August 22nd release.  Due to the cooler-than-normal
temperatures (2 to 3 degrees) this month, this dryness is having
little impact at this time.

SUMMARY OF IMPACTS...

LOCAL AREA AFFECTED.

Abnormally dry (D1) to moderate drought (D1) across all or portions of
Allamakee and Winneshiek counties in northeast Iowa and Fillmore and
Houston counties in southeast Minnesota.

STATE /LOCAL GOVERNMENT ACTIONS.

No know actions are currently taking place.

SOIL MOISTURE CONDITIONS.

Northeast Iowa...

Topsoil moisture was rated 1 percent very short, 25 percent short,
and 74 percent adequate.   Subsoil moisture was rated 0 percent very
short, 19 percent short, 80 percent adequate, and 1 percent surplus.

Minnesota...

AGRICULTURE IMPACTS.

Iowa...

According to USDA`s National Agricultural Statistics Service during
the week ending August 20, 2017, much needed rain fell throughout
the state of Iowa.  Statewide there were 4.8 days suitable for
fieldwork.  Activities for the week included haying and hauling
grain.

Seasonally mild temperatures prevailed through most of the week
while rainfall was more widespread and frequent than in recent
weeks.  Weekly rain totals were generally below normal across the
east one-third of Iowa and above normal over much of the remainder
of the state.  The statewide average rainfall was 1.35 inches while
normal for the week is 0.97 inches.  The coolest weather in most
areas came on Sunday (13th) when highs were mostly in the seventies
statewide.  The remainder of the week was mostly cooler than normal
over the north and slightly above normal over the far south.
Temperature extremes ranged from afternoon highs of 92 degrees at
Donnellson on Tuesday and at Osceola on Saturday to a Saturday
morning low of 49 degrees at Cresco.  Temperatures for the week as a
whole averaged two to three degrees below normal across northeast
Iowa to about one degree above normal over the far south.

Minnesota...

According to USDA`s National Agricultural Statistics Service during
the week ending August 20, 2017, widespread rainfall limited
Minnesota farmers to only 2.6 days suitable for fieldwork. That was
the fewest days suitable for field work in any week since late May.
Activities for the week included harvesting small grains and
spraying crops in areas where possible.

FIRE DANGER HAZARDS.

As of the morning of August 23rd, low fire danger was reported
across Allamakee and Winneshiek counties in northeast Iowa and
Fillmore and Houston counties in southeast Minnesota.

As a reminder, citizens should always check with local officials in
their area before undertaking any outside burning.  Citizens are
liable for damages and suppression costs of any wildfire they may
start.

RIVER AND STREAM FLOW CONDITIONS.

The flow along the Turkey and Upper Iowa in northeast Iowa and the
Root River in southeast Minnesota was normal to above normal.

CLIMATOLOGICAL SUMMARY...

Since mid-June, rainfall totals ranged from 4.36 inches at Preston-
Fillmore Airport (Fillmore County) in southeast Minnesota to 10.91
inches at Calmar IA (Winneshiek County).  These rainfall totals were
anywhere from 4 to 6 inches below normal for the counties of
Allamakee and Winneshiek in northeast Iowa and Fillmore and Houston
in southeast Minnesota.  Due to the cooler-than-normal temperatures
(2 to 3 degrees) this month, this current dryness is having little
impact at this time.

PRECIPITATION/TEMPERATURE OUTLOOKS...

From August 24th through August 30th, temperature will average below
normal and precipitation will average near to above-normal. During
this time frame, the daily average temperatures range from 65 to 70
degrees and the normal precipitation is around nine tenths of an
inch.

Beyond this time frame the 8 to 14 day forecast (August 31st through
September 6th) from the Climate Prediction Center (CPC) calls for
enhanced chances of below-normal temperatures and near- to below-
normal precipitation.  During this time frame, the daily average
temperatures range from 63 to 68 degrees and the normal
precipitation is around nine tenths of an inch.

The CPC seasonal outlook for meteorological autumn calls for
enhanced chances of above-normal temperatures and equal chances of
above-, near-, and below-normal precipitation across the Upper
Mississippi River Valley.

HYDROLOGIC SUMMARY AND OUTLOOK...

Rainfall from today through early next week may result in some
improvements in the drought situation across parts of northeast Iowa
and southeast Minnesota.

NEXT ISSUANCE DATE...

This product will be updated on Thursday, August 31st.
