This Hazardous Weather Outlook is for portions of North Central
Illinois...Northeast Illinois and Northwest Indiana.



Weather hazards expected...

Elevated Thunderstorm Risk...with an associated:
Limited Damaging Wind Risk...up to 60 mph.
Elevated Flooding Risk.
High Swim Risk

DISCUSSION...

Scattered thunderstorms will occur this morning, gradually
shifting south. By early afternoon, the thunderstorm potential
should be mainly south of Interstate 80, with scattered
thunderstorms likely there this afternoon. A few of these may
produce strong to damaging wind gusts. In addition, temporary
heavy rainfall rates are likely with any storms today, and if
any do track over the same areas, could result in localized
flash flooding.

Increasing northerly winds today will result in building waves
along the Lake Michigan shore by early to mid afternoon. This
will create dangerous swimming conditions especially from
Chicago south and east.



Monday...
High Swim Risk
Friday and Saturday...
Limited Thunderstorm Risk.

DISCUSSION:

Breezy northerly winds over Lake Michigan on Monday will
continue to build waves along Illinois and Indiana beaches.
This will result in dangerous swimming conditions.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated, though there may be
a couple severe storms south of I-80 this afternoon.

GENERAL STORM MOTION OF THE DAY:

Moving toward the east at 25 mph.
