...Moderate to Severe Drought Conditions Now Exist Across Portions of
Northeast Illinois and Northwest Indiana...
Many areas of northern Illinois northwest and Indiana have
received significantly below average rainfall since the beginning
of spring. For example, Midway Airport in Chicago, Illinois, has
recorded just 2.72 inches of precipitation since April 1, which is
7.1 inches below the 30-year average and the second lowest since
the early 1900s. Similar rainfall deficits are present across much
of northeast Illinois and far northwest Indiana. Drought conditions
have thus further deteriorated across much of the area.
Severe drought conditions are now present across portions of far
northeastern Illinois and far northwestern Indiana, including the
Chicago metropolitan area. Severe drought conditions are now
present in multiple areas in northern Illinois and northwest
Indiana, including the Chicago metropolitan area. Moderate drought
conditions cover corridor from west central Illinois through
northern Indiana outside of the severe drought area.
SUMMARY OF IMPACTS...
Volunteer observers across the area indicate lower than typical
water levels in ponds and streams. Reports also indicate that some
lawns have gone dormant. There has also been stress to trees and
shrubs. Limited impacts to agriculture have been reported,
including reduced growth rates. Data available from the Illinois
State Water Survey, USGS, and NCEP indicate that soil moisture,
groundwater, and surface water levels remain below normal.
Over the last 30 days, rainfall in northeast Illinois and
northwest Indiana has ranged from 5% to 75% of average. The most
significant rainfall deficits over the last 30 days were located
near the Chicago metro area, including Cook, DuPage, Will, and
Lake (IL) counties.
There are only very limited chances for rainfall over the next 7
days, with amounts across the greater Midwest region generally
forecast to be less than 0.5 inches. Dry and warm conditions are
forecast next week, with highs in the 80s.
The Climate Prediction Center`s (CPC) 30-Day Outlook indicates no
strong signal for above or below average preciptiation over the
next 6-10 days or the next 7-14 days.
HYDROLOGIC SUMMARY AND OUTLOOK...
For most rivers in northern Illinois streamflow values are below
average for this time of year. Multiple small streams are near the
lowest observed streamflow levels for mid-June. Without additional
rainfall, river and stream levels will remain below average or
At many locations, groundwater and soil moisture remain below
average. Without additional rainfall, soil moisture and groundwater
levels will remain at low levels.
