...Abnormally Dry and Drought Conditions Expand...

SYNOPSIS...

Since late July (the last 45 days), very little rain has fallen
along and south of the Interstate 90 corridor.  Rainfall deficits
during this time frame range from 3 to 5.50 inches.  Due to this
dryness, the abnormally dry (D0) conditions have expanded across
southwest and west-central Wisconsin, north-central Iowa, and south-
central Minnesota.

There were even larger rainfall deficits (4 to 8 inches) found in
Fillmore and Houston in southeast Minnesota, and Allamakee, Howard,
and Winneshiek counties in northeast Iowa since June 1st.  Due to
this, the moderate (D1) drought was expanded in these counties. In
addition, a small area of severe (D2) drought was added to Allamakee
County

.SUMMARY OF IMPACTS...

LOCAL AREA AFFECTED.

Moderate (D1) to severe (D2) drought across Allamakee
County.

Abnormally dry (D0) to moderate drought (D1) across all or
portions of Howard, and Winneshiek counties in northeast Iowa and
Fillmore and Houston counties in southeast Minnesota.

Abnormally dry (D0) across all or parts of Chickasaw, Clayton,
Fayette, Floyd, and Mitchell counties in northeast Iowa;  Mower,
Olmsted, and Winona counties in southeast Minnesota; and Buffalo,

AGRICULTURE IMPACTS.

Iowa...

According to USDA`s National Agricultural Statistics Service during
the week ending September 10, 2017, it was another dry week in Iowa
with only localized showers during the week ending. Statewide there
were 6.8 days suitable for fieldwork. Activities for the week
included cutting hay, chopping corn for silage, seeding cover crops,
hauling grain, and preparing for grain harvest.

Pasture conditions declined to 41 percent poor to very poor due to
continued dry conditions slowing growth.

It was a very dry week across Iowa with mostly below normal
temperatures. Very light rain fell over portions of north central
and northeast Iowa on Monday (4th) and Tuesday (5th) with Britt
reporting the most rain with only 0.13 inches. The statewide average
rainfall was 0.03 inches while normal for the week is 0.84 inches.
This was the driest week since mid-February.

Meanwhile, temperatures were above normal on Sunday (3rd) and again
the next Saturday (9th). In between unseasonably cool weather
prevailed for the work week, especially on Tuesday (5th) and
Wednesday (6th) when daytime highs were only in the sixties in most
areas. Temperature extremes for the week varied from a Sunday (3rd)
afternoon high of 88 degrees at Oskaloosa to a Thursday (7th)
morning low of 35 degrees at Stanley (Buchanan County). The
statewide average temperature was 4.0 degrees below normal for the
week.

Minnesota...

According to USDA`s National Agricultural Statistics Service during
the week ending September 10, 2017, Minnesota farmers have nearly
completed small grain harvest and have begun harvesting dry edible
beans and corn for silage. There were 6.2 days suitable for
fieldwork, the second most of any week this year. Field activities
included fall tillage, spreading manure, and seeding cover
crops.

Wisconsin...

According to USDA`s National Agricultural Statistics Service during
the week ending September 10, 2017, there were 5.6 days suitable for
fieldwork for the week.  Dry and cool conditions continued this
week, with overnight temperatures in the 40s statewide.  Rains were
light and scattered, allowing wet fields to dry, while the southwest
continues to need rain. Haying continues, and the oat harvest is
moving slow in many areas. Late-planted corn and soybeans were still
struggling to mature in some areas.  There were some reports of
white mold in soybean fields.

Vernon County could use a good rain. Pasture growth has slowed down.

FIRE DANGER HAZARDS.

As of the morning of September 12th, low fire danger was reported
across northeast Iowa, southeast Minnesota, and western Wisconsin.

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.

Normal flows continue along rivers and streams in northeast Iowa,
southeast Minnesota, and western Wisconsin

.CLIMATOLOGICAL SUMMARY...

During the last 45 days (July 30 to September 12), the rainfall
deficits have ranged from 3 to 5.5 inches along and south of the
Interstate 90 corridor. Guttentberg Lock and Dam 10 IA (0.64
inches), Lancaster 4 WSW WI (0.71 inches), Prairie du Chien WI (0.71
inches), and  Decorah IA (0.98 inches) did not even receive an inch
of rain during this time period.

Since June 1st, the rainfall deficits in the drought areas southeast
Minnesota and northeast Iowa range from 4 to 8 inches. The highest
deficit was 8.03" in Caledonia, MN (Houston County).

PRECIPITATION/TEMPERATURE OUTLOOKS...

From September 15th through September 20th, temperatures will
average above normal and precipitation will average below normal.
During this time frame, the daily average temperatures range from 57
to 62 degrees and the normal precipitation is around 7 tenths of an
inch.

Beyond this time frame the 8 to 14 day forecast (September
21st through September 27th) from the Climate Prediction Center
(CPC) calls for enhanced chances of above-normal temperatures and
precipitation.  During this time frame, the daily average
temperatures range from 54 to 59 degrees and the normal
precipitation is around 8 tenths of an inch.

The CPC seasonal outlook for October through December 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...

With below normal rainfall expected through the next week, no
improvement is expected in the drought situation across parts of
northeast Iowa and southeast Minnesota or the abnormally dry
conditions across southwest and west-central Wisconsin.

NEXT ISSUANCE DATE...

This product will be updated on Thursday, September 21st.
