central Iowa...northeast Iowa...southeast Iowa and northeast

.DAY ONE...TONIGHT

Rounds of moderate to heavy rainfall are possible late tonight,
mainly along and south of Interstate 80. Additional heavy rain
will produce elevated levels on small creeks and streams, ponding
of water in urban areas, on roads, underpasses, as well as other
poor drainage areas and low lying spots. Isolated flash flooding
is possible late tonight, especially across portions of Hancock,
McDonough, Bureau, and Putnam Counties where the heaviest rain
fell earlier Saturday. Isolated non-severe thunderstorms are
possible late tonight.

Many area rivers are rising due to recent heavy rain and
additional rain forecast through Sunday night. Please see the
latest Flood Statements and Flood Warnings for details.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

Widespread rain and embedded thunderstorms will continue Sunday
morning through Sunday evening. Through Sunday night, widespread
rainfall amounts of 3 inches or more are possible over parts of
west central into northwest Illinois. River flood watches and
warnings continue for many area tributary rivers and the
Mississippi River. Those with interests along area rivers,
streams and creeks should check back for updates through 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, and possibly a tornado. Isolated flash
flooding is also possible Sunday and Sunday evening.
