Illinois...northwest Illinois...west central Illinois...east
central Iowa...northeast Iowa...southeast Iowa and northeast
Missouri.

.DAY ONE...TODAY AND TONIGHT

Heavy rain, embedded thunderstorms, and gusty winds will continue
through late morning. There is just a low chance that a storm or
heavier shower will produce damaging wind gusts. Some ponding of

gust 30 to 40 MPH initially from the south this morning. They will
then switch to the west by this afternoon and possibly gust up to
45 MPH, especially south of Interstate 80.

The heavy rain could lead to rises and flooding on area tributary
rivers. River flood watches continue for portions of the Rock and
Wapsipinicon Rivers.

A storm system may bring accumulating snow to the region Thursday
night through Friday. It is too early to determine snow amounts and

this morning. Any reports of an inch or more of rain would be
appreciated.
