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


There is an enhanced risk for severe thunderstorms south of
Interstate 80 and west of the Mississippi River late tonight.

There is a higher chance for thunderstorms mainly after 5 AM in
the western portion of the outlook area. This round of storms may
become severe, with damaging wind gusts the primary threat.
Isolated, brief tornadoes cannot be ruled out at this time. These
storms will also produce torrential rainfall as they pass by,
producing ponding of water and sharply reduced visibility.


There is an enhanced risk for severe storms along and south of
Interstate 80 Tuesday morning.

A line of thunderstorms is still expected to move across portions
of the Outlook area Tuesday morning. The primary threats from
these storms will be damaging winds, frequent lightning and
torrential downpours. Latest indications suggest that most of the
line of severe storms will occur along and south of Interstate 80
Tuesday morning. There is also at least a low chance for isolated
flash flooding by high rainfall rates in areas of repeated storm
activity. Current expectations are that the brunt of the severe
storms will exit east of the Outlook Area by 10 AM.

There is a chance of thunderstorms again late Tuesday night through
Wednesday, mainly across southeast Iowa, northeast Missouri, and
west central Illinois. The threat for severe weather appears low
at this time.

Additional storm chances will exist over the latter half of this
weekend. It is too early to determine the threat for severe
weather with these storms.


Spotter and amateur radio activation will be needed late tonight
and Tuesday morning.
