## extract

Hydrologic Outlook — Boone, IL; Cook, IL; De Kalb, IL; DuPage, IL; Grundy, IL; Kane, IL; Kendall, IL; Lake, IL; La Salle, IL; Lee, IL; McHenry, IL; Ogle, IL; Will, IL; Winnebago, IL; Lake, IN
Severity: Unknown. Certainty: Possible.
ESFLOT

Several rounds of showers and thunderstorms are possible starting
late Friday night and continuing into Monday across southern
Wisconsin, northern Illinois, and part of northwestern Indiana. High
moisture content in the atmosphere will lead to torrential downpours
where thunderstorms are most frequent, leading to the potential for
several inches of rain on a widespread basis.

The favored area for several rounds of showers and thunderstorms
Friday night through Monday will be near and north of Interstate 80
where several inches of rain have fallen in the past 24 hours. The
intersection of increasingly saturated soils and repeated downpours
may lead to areas of flooding and rises in river levels, including
along the Rock, Fox, DuPage, and Illinois rivers.

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.

Additional statements or outlooks may be issued by tomorrow morning.
