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

Areas of dense fog reducing visibility down to a quarter mile or
less will last through 8 AM before clouds and thunderstorms move
in from the west. A Dense Fog Advisory is in effect for most of
the Outlook Area this morning.

A strong to severe storm system will move in from the west and
impact much of the Outlook Area this morning through midday.
Damaging winds, potentially up to 70 mph, will be the primary
risk. Brief spin-up tornadoes will be a secondary risk. Areas
along and south of the Highway 30 corridor are in a Slight Risk,
level 2 out of 5, for severe storms today. Locally heavy rainfall
and flash flooding will also be a concern.

More thunderstorms are expected to develop tonight. With the
potential for lines of storms to repeatedly develop and move
across the same areas, the primary concern tonight will be
torrential rainfall and flash flooding. Isolated severe storms
with damaging winds and hail will also still be possible. Most of
the Outlook Area is in a Flood Watch today through midday Friday.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

Rounds of strong to severe storms will be possible Friday and
Saturday as the area remains in an active storm track. There is a
Marginal Risk, level 1 of 5, for severe storms both days for much
of the area. Locally heavy rain and flash flooding will also be a
concern, especially Friday night if storms move across areas
already soaked from previous bouts of heavy rainfall.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is likely today and possible tonight.
