Drought Information Statement
National Weather Service Quad Cities IA IL
405 PM CDT Thu Sep 14 2017

...Drought intensifies over eastern Iowa, northwest Illinois and
northeast Missouri...

SYNOPSIS...
A multi-month period of drier than normal weather starting last
winter has evolved into moderate to severe drought across parts of
Iowa. Abnormally dry conditions cover parts of northwest Illinois
and northeast Missouri.

Temperatures last week ended up a few degrees below normal, but no
rain fell hence the expansion of the drought area.

LOCAL AREA AFFECTED...
Within our service area, moderate drought extends roughly from
Vinton, Iowa to Cedar Rapids with a second area southwest of a line
from Sigourney to Wapello. Severe drought exists over much of
Jefferson, Van Buren and Henry counties. Outside of these areas,
conditions are rated abnormally dry.

SUMMARY OF IMPACTS...

STATE/LOCAL GOVERNMENT ACTIONS.
Iowa State University Extension and Outreach Service drought page:
https://www.extension.iastate.edu/topic/dealing-drought-2017

SOIL MOISTURE CONDITIONS.
USDA reports for southeast Iowa indicate topsoil moisture is 83%
short or very short, and subsoil moisture was 86% short or very
short. In northwest Illinois the reports were 78 and 62%
respectively.

AGRICULTURAL IMPACTS.
Roughly about half of the Iowa corn and soybean crop respectively
statewide is rated fair to very poor. Corn and soybean development
is running behind normal due to the cooler weather. Crop condition
was slightly better in Illinois.

RIVER AND STREAM FLOW CONDITIONS.
Streamflows in southeast Iowa and northeast Missouri are running
generally below normal in most areas. Elsewhere streamflows are near
or even above normal.

GROUND WATER IMPACTS.
Some improvement to shallow groundwater levels has been noted in
parts of southeast Iowa.

FIRE DANGER IMPACTS.
Burn bans are not currently in effect in southeast Iowa, but they
are in effect for Mahaska, Monroe and Wapello counties. Recent and
forecast dry weather will promote rapid curing of native vegetation.

CLIMATE SUMMARY...
Fairfield Iowa (representative of the drought area)
Since Jan 1 - actual precipitation is 16.08, normal is 28.38. Only
3.51 inches has fallen during the summer (June-July-August) making it
the driest summer on record. Normal summer rainfall totals 12.86
inches. No rain has yet fallen in September. 2017 is running slight
wetter than the driest year on record, 1988.

PRECIPITATION/TEMPERATURE OUTLOOK...
WEEK 1: There is a chance of rain this weekend, but if rain occurs,
amounts are not expected to significantly impact the drought. There
are indications of a switch to a wetter pattern next week, but
whether rainfall will be sufficient to impact the drought is not yet
known.

WEEK 2: Odds favor above normal precipitation and temperatures
(September 22-28).

The outlook for September-October-November favors near to above
normal temperatures, with no indication either way of drier or
wetter than normal conditions.

HYDROLOGICAL OUTLOOK...
A lack of rain will keep rivers at low levels or slowly falling in
the drought areas.
