...No Change in the Drought Situation across Northeast Iowa &
Southeast Minnesota...

SYNOPSIS...

Through June 1st deficits have grown to 3 to 7 inches across
Allamakee, Howard and Winneshiek counties in northeast Iowa and
Fillmore and Houston counties in southeast Minnesota.  This has
resulted in abnormally dry (D0) to moderate drought (D1) conditions
developing in these counties. Fortunately, the cooler-than-normal
August temperatures (2 to 3 degrees) have limited the impacts.

In the September 5th release of the U.S. Drought Monitor, severe
(D2) to extreme drought (D3) was found in south-central and
southeast Iowa.  Moderate drought (D1) was found in northwest
Minnesota; northwest into central Iowa; northeast Iowa; central
Illinois; and a small portion of southeast Minnesota.  Abnormally
dry conditions (D0) were found across southern Lower Michigan and
southwest Iowa.

SUMMARY OF IMPACTS...

LOCAL AREA AFFECTED.

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

STATE /LOCAL GOVERNMENT ACTIONS.

No actions are currently taking place.

SOIL MOISTURE CONDITIONS.

Northeast Iowa...

Topsoil moisture levels rated 13 percent very short, 27 percent
short, 59 percent adequate and 1 percent surplus.  According to the
August 29, 2017 U.S. Drought Monitor, areas of south central and
southeast Iowa have been in a severe drought for 5 consecutive
weeks. Subsoil moisture levels rated 17 percent very short, 31

AGRICULTURE IMPACTS.

Iowa...

According to USDA`s National Agricultural Statistics Service during
the week ending September 3, 2017, it was a cool dry week in Iowa.
Statewide there were 6.2 days suitable for fieldwork. Activities for
the week included haying, hauling grain, chopping corn silage,
seeding cover crops, and harvesting seed corn.

Temperatures were below normal throughout the week except at a few
western Iowa locations. Monday (28th) and Friday (1st) were the
coolest days in most areas with daytime highs in the seventies.
Temperature extremes for the week ranged from Friday (1st) morning
lows of 41 degrees at Cresco and Elkader to a Saturday (2nd)
afternoon high of 86 degrees at Albia. Temperatures for the week as
a whole averaged from four to seven degrees below normal over the
east to slightly above normal in the far northwest with a statewide
average of 3.0 degrees subnormal.

Most of the week`s rain came on Sunday (27th) when rain was
scattered nearly statewide with some very small areas of heavy rain
in the Dubuque and Burlington areas. There were some thunderstorms
on Monday over extreme eastern Iowa, with some localized heavy rains
around Burlington.  There were some isolated showers on Thursday
(31st), Friday (1st) and Saturday (2nd) but with rain totals mostly
under one-tenth of an inch.  Asbury in Dubuque County reported the
most rain for the week with 3.31 inches while Burlington saw 2.72
inches. Much of central and south central Iowa saw little, if any
rain.  The statewide average rainfall amount was 0.11 inches while
normal for the week is 0.88 inches.

This was the state`s driest week in 12 weeks (mid-June).  At
Fairfield the summer rainfall total (June-August) was only 3.51
inches.  This was their lowest summer rain total among 137 years of
records at that location (old record 3.77 inches in 1911).  The
Ottumwa Airport recorded even less rain for the summer with 3.38
inches, but this amount ranked a distant second behind 1911`s 1.80
inch total at that location.

Minnesota...

According to USDA`s National Agricultural Statistics Service during
the week ending September 3, 2017, warm and dry conditions in
western Minnesota aided small grain harvest and row crop
development. There were 5.0 days suitable for fieldwork. Field
activities included harvesting small grains, hauling manure and
readying equipment for dry bean and sugar beet harvest.

FIRE DANGER HAZARDS.

As of the morning of September 5th, low fire danger was reported
across Allamakee, Howard, 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 June 1st, rainfall totals ranged from 6.32 inches at Preston-
Fillmore Airport (Fillmore County) in southeast Minnesota to 13.65
inches just northwest of Hokah MN (Houston County).  These rainfall
totals were anywhere from 3 to 7 inches below normal for the
counties of Allamakee, Howard, and Winneshiek in northeast Iowa and
Fillmore and Houston in southeast Minnesota.   Some of the
precipitation deficits include:  3.38 inches at Preston MN, 3.35
inches at Cresco IA, and 5.53 inches at Caledonia MN.Due to the
cooler-than-normal August and early September, temperatures (2 to 3
degrees), this current dryness is causing limited impacts.

PRECIPITATION/TEMPERATURE OUTLOOKS...

From September 7th through September 13th, temperatures will average
near normal and precipitation will average below normal.  During
this time frame, the daily average temperatures range from 60 to 65
degrees and the normal precipitation is around nine tenths of an
inch.

Beyond this time frame the 8 to 14 day forecast (September
14th through September 20th) from the Climate Prediction Center
(CPC) calls for enhanced chances of above-normal temperatures and
below-normal precipitation.  During this time frame, the daily
average temperatures range from 57 to 62 degrees and the normal
precipitation is around eight 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 little rainfall expected through the next week, no improvement
is expected in the drought situation across parts of northeast Iowa
and southeast Minnesota.

NEXT ISSUANCE DATE...

This product will be updated on Friday, September 15th.
