DROUGHT INFORMATION STATEMENT

...SLIGHT IMPROVEMENT, BUT OVERALL NO MAJOR CHANGES TO SEVERE
DROUGHT CONDITIONS IN SOUTHERN WISCONSIN...

.SYNOPSIS:
The September 16th Drought Monitor continues to indicate Severe
Drought (D2) across eastern Walworth county and for all of Racine
and Kenosha counties. The only change to the drought monitor this
week was a reduction of Moderate Drought (D1) along Highway 14 in
Iowa and western Dane counties and along the I-94 corridor in
eastern Dane, Jefferson, and western Waukesha counties due to
heavy rain along a stalled frontal boundary at the beginning of
this week. Otherwise, Moderate Drought (D1) continues across far
southern portions of Iowa, Dane, Jefferson, Waukesha, and
Milwaukee counties as well as all of Lafayette, Green, Rock, and
western Walworth counties. There is also a pocket of Moderate
Drought (D1) for portions of northern Dane and Jefferson counties
and southern portions of Columbia and Dodge counties with a
little extension into far southwestern Washington county.
Abnormally dry (D0) conditions exist across northern Iowa, central
Sauk, northern Columbia, northern Dodge, Washington, Ozaukee
counties as well as along the I-94 across central Dane, Jefferson,
northern Waukesha, and Milwaukee counties.


.Precipitation:
Most of southern Wisconsin saw precipitation ranging from 0.1 inch
to around 2.0 inches within the last week. The heaviest rain fell
between Sunday and Monday along the Highway 14 and I-94 corridor
from Iowa county into Waukesha county with most locations seeing
1.0 to 2.0 inches. A few isolated spots in Jefferson County saw
locally higher amounts greater than 2.0 inches. However, areas
along the WI/IL border where much of the moderate and severe
drought persists has missed out on the much needed precipitation
and continue to experience long term dryness. 180 day
precipitation in those areas continue to see 4.0 to 10.0 inches
deficits. There are still positive 30 day precipitation anomalies
for western Iowa and southwest Walworth counties along with near
normal rainfall along the Highway 14 and I-94 corridors from Iowa
into western Waukesha counties. Drought conditions in some of
those areas improved in recent weeks. Otherwise, 30 day
precipitation deficits range from 0.5 to 2.0 inches across parts
of the moderate drought areas.


Hydrologic Conditions:
Streamflows across much of southern Wisconsin are in the normal
and above normal categories. However, areas in Severe Drought
(D2) in southeastern Wisconsin are seeing below normal streamflow.


.Summary of Impacts:
As of September 12th in south-central Wisconsin 23% of topsoil is
rated very short, 28% is rated as short, and 49% is rated as
adequate. In southeast Wisconsin 53% of topsoil is rated very
short, 19% short, and 28% adequate. In south-central Wisconsin
21% of subsoil moisture is rated very short, 26% short and 53%
adequate. In southeast Wisconsin 54% of subsoil moisture is rated
very short, 16% short, and 30% adequate.


.Drought Mitigation Actions:
None reported.

.Local Drought Outlook:
Next chance at precipitation will be Friday, September 17th with
amounts ranging up to 0.5 an inch as a cold front pushes through
the region and then this upcoming weekend looks dry. There will
be another potential for precipitation early next week with a
deepening system over the region. The week two outlook, valid
September 23-29, indicates a signal for slightly below normal
precipitation for most of southern Wisconsin, but there remains a
degree of uncertainty in these extended outlooks. The outlook for
the September- October- November time frame shows little signal
one way or the other.

.Next issuance date:
The next outlook will be issued September 23rd after the release
of the updated Drought Monitor.
