HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE CHICAGO IL
219 PM CDT THU APR 16 2026
...ANOTHER ROUND OF THUNDERSTORMS EXPECTED FRIDAY AFTERNOON AND
FRIDAY NIGHT...
ADDITIONAL THUNDERSTORMS ARE EXPECTED FRIDAY AFTERNOON AND FRIDAY
NIGHT ACROSS NORTHERN ILLINOIS AND NORTHWEST INDIANA. ATMOSPHERIC
CONDITIONS ARE FAVORABLE FOR SOME OF THESE STORMS TO PRODUCE LOCALLY
HEAVY RAINFALL.
MANY RIVERS ACROSS NORTHERN ILLINOIS AND NORTHWEST INDIANA REMAIN
ELEVATED. SOIL MOISTURE ALSO REMAINS ELEVATED IN MANY AREAS,
ESPECIALLY IN NORTHERN ILLINOIS ALONG THE WISCONSIN BORDER. THUS,
ANY HEAVY RAINFALL THAT OCCURS COULD LEAD TO FLOODING OF RIVERS,
CREEKS, URBAN AND LOW-LYING AREAS. RIVERS SUCH AS THE ROCK, FOX AND
DES PLAINES WHICH ARE ALREADY IN FLOOD IN SOME LOCATIONS, MAY BE
ESPECIALLY PRONE TO RAINFALL WHICH COULD EXACERBATE ONGOING FLOODING.
THIS OUTLOOK MEANS THAT ELEVATED WATER LEVELS AND POTENTIAL IMPACTS
ARE POSSIBLE, BUT NOT YET CERTAIN. PERSONS SHOULD CLOSELY MONITOR
FORECASTS INCLUDING THE POSSIBILITY OF FLOOD WATCHES, WARNINGS, AND
ADVISORIES.
THIS OUTLOOK WILL BE UPDATED BY FRIDAY MORNING.
