...Heavy rainfall possible this weekend...

A slow-moving storm system moving into the area by late this
weekend has the potential to produce heavy rainfall across the
area. This system may bring renewed flooding to the area,
especially if heavy rainfall occurs in the Des Plaines, Fox, and
Rock River Basins which continue to run at elevated levels. The
flood potential exists from primarily Saturday night through at
least early next week.

Over the last week, 2 to 6 inches of rainfall has occurred across
portions of far northern Illinois and southern Wisconsin, with
5 to 10 inches over the last two weeks. This wet weather has
contributed to elevated soil moisture and water levels.

Several rounds of rainfall will be possible from Saturday
afternoon through Sunday evening. Widespread rainfall amounts of
one to three inches are possible across the region, with localized
amounts of three to five inches. However, the exact location of
heaviest rainfall remains uncertain at this time. If repeated
rounds of heavy rainfall occur, flash flooding and subsequent rises
on area rivers would be possible.

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.
