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


Showers and a few thunderstorms today may lead to flooding along
streams and low lying areas. Conditions are already saturated
due to heavy rainfall over the past couple days and frozen
ground. A flood watch remains in effect for much of the outlook
area today.

Some freezing rain may produce some light ice accumulations on
elevated and untreated surfaces through mid afternoon across
portions of southeastern Iowa and far northeastern Missouri.

Another round of wintry mix including freezing rain, may be
possible along and east of the Mississippi River across west
central Illinois up toward and northeast of the Princeton
Illinois area after dark this evening, and linger through at
least mid evening.

Flooding along area rivers is expected to develop today and
intensify over the next several days. Please see the latest river
flood warnings and statements for details.


Two separate storm systems will move through the area Wednesday
night through Friday morning. There is some uncertainty regarding
the track of each storm which will determine precipitation type.

The first storm may produce light snow Wednesday night that
changes to rain on Thursday.

Thursday night into Friday morning the second storm system has
the potential to produce snow, sleet, and freezing rain.

Friday night through Saturday night two more storm systems will
move through the area. The tracks of both storms are uncertain but
the potential is there for rain changing to snow at night.

Flooding is expected on many area tributary rivers. Please see the
latest flood statements and warnings for details.


Spotter activation is not expected. However, reports of rainfall
amounts greater than one inch, freezing rain, and flooding will
be appreciated.
