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

Some patchy dense fog, reducing visibilities down to a quarter
mile or less, will continue through 8 AM CDT across portions of
southeastern Iowa, far northeastern Missouri, and west central
Illinois.

Scattered thunderstorms may develop this afternoon across areas
north of Interstate 80 and west of the Mississippi River. There is
just a low chance of severe weather with these storms.

A larger area of thunderstorms is expected to move eastward across
the Outlook area from mid evening and into the overnight. There is
a chance for some severe storms tonight, especially south of
Interstate 80. Large hail and damaging winds will be the main
threats. An isolated tornado will be possible along the Iowa-
Missouri border region. Locally heavy rainfall will be likley
under any passing thunderstorm cluster.

Flooding will continue along portions of the Mississippi River
into next week.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

More thunderstorms may fire across portions of the area Sunday
afternoon. The better chances for stronger storms will occur
across west central Illinois into central Illinois, if enough
daytime heating can occur after morning clouds and storms
decrease.

Thunderstorm chances will continue off and on across portions of
the Outlook area for much of next week. It is too early to
determine any severe weather risk for this period.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed for portions of the Outlook Area
by tonight.
