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...THIS AFTERNOON AND TONIGHT

Scattered thunderstorms are expected late this afternoon and
evening. Latest indications suggest the best chances for storms
are in the counties south of Interstate 80, and especially along
and south of a line generally from Fairfield Iowa, to Princeton
Illinois. A few storms could be severe with the main risks being
damaging winds and large hail.

Widespread coverage of showers and storms is still not
anticipated, so several locations will receive little to no rain.

Later tonight, patchy to areas of fog may develop after midnight
and toward dawn, with some chance of locally dense fog reducing
visibilties down to a quarter mile.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

Thunderstorms are possible across the outlook area from late
Sunday through Tuesday. It is still too soon to determine the
potential for severe weather, but heavy rainfall may be possible.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed this afternoon and evening,
especially south of Interstate 80.
