This Hazardous Weather Outlook is for portions of north central
Illinois...northwest Illinois...west central Illinois...east
central Iowa...northeast Iowa...southeast Iowa and northeast


Area rivers are experiencing flooding. Please see the
latest Flood Statements and Flood Warnings for details.


Confidence is increasing on the potential for widespread heavy rain
through the weekend. Parts of west central and northwest Illinois
remain favored for the heaviest amounts, potentially 2 to 3 inches
and locally higher, along with isolated flash flooding. These
amounts are now being reflected in the river forecast models and
place the Illinois tribs and the Mississippi River south of the Quad
Cities at the most risk of significant flooding. Moderate flooding
is possible into next week on the Rock River, as well as the La
Moine River, and the mainstem Mississippi from New Boston to
Burlington. There is still some uncertainty on the axis of heavy
rain, and those with interests along area rivers, streams and creeks
should check back for updates through the weekend.

Scattered thunderstorms are expected over the weekend. Isolated
severe storms are possible Sunday afternoon and evening, but
confidence remains low. If severe storms occur, the main threats
would be damaging winds, localized flash flooding, and possibly a


Spotter activation may be needed over the weekend for reports of
heavy rain, flooding, and severe weather.
