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
Missouri.

.DAY ONE...TODAY AND TONIGHT

Isolated thunderstorms will be possible north of Interstate 80
this afternoon. These storms are not expected to be severe.
Thunderstorms of more scattered coverage are expected to develop
later tonight, especially along and south of the Interstate 80
corridor. There is a low chance that some of these storms will be
able to produce large hail. The Storm Prediction Center has
placed areas generally along and south of a line from Cedar Rapids
Iowa, to just southeast of the Quad Cities in a marginal risk for
severe weather tonight.

Areas that experience repeated storms tonight may get locally
heavy rainfall of over an inch which may produce ponding of water
on roads and in drainage ditches.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

Periods of showers and thunderstorms will continue Saturday and
Saturday night. Areas south of Interstate 80, from Williamsburg to the
Quad Cities, are most favored for severe storms Saturday afternoon and
evening. The main threats are damaging winds to 60 mph and isolated
tornadoes.

Widespread heavy rain is also expected through Saturday night. Pockets
of more than 3 inches are possible. Repeat thunderstorms and high
rainfall rates could produce flash flooding.

Patchy frost is possible early Monday morning, especially north of
Interstate 80.

.SPOTTER INFORMATION STATEMENT...

There is a low chance that spotter activation will be needed
tonight. Spotter activation is more likely for Saturday afternoon
and evening.
