Widely scattered thunderstorms this Friday afternoon/evening to have little or no impact on area rivers/streams

Weather

There will be about a 10 to 20 percent chance of thunderstorms occurring within 12 miles of a given location ahead of a cold front that will move southeast across northern Illinois this Friday afternoon into northwest Indiana this evening (see brown-shaded area on the thunderstorm outlook map below). The National Storm Prediction Center has the Chicago area in a Marginal Risk for any of the thunderstorms possibly producing damaging winds or large hail (dark green-shaded area on the severe weather outlook map below).

Chicago-area rivers will be largely unaffected by the widely scattered t-storms – continuing a slow steady decline. The segment of the Illinois River from Starved Rock to LaSalle will fall from Minor Flooding today to below flood Saturday morning.

The Hydrologic Summary of river stages and flood forecast issued earlier this Friday morning by the Chicago National Weather Service is provided below.
