* WHAT...Very cold wind chills of 15 to 25 degrees below zero
expected.

* WHERE...Portions of central, east central, north central, and
northeast Illinois and northwest Indiana.

* WHEN...Until noon CST /1 PM EST/ Sunday.

* IMPACTS...The dangerously cold wind chills as low as 25 below zero
could cause frostbite on exposed skin in as little as 30 minutes.

Use caution while traveling outside. Wear appropriate clothing, a
hat, and gloves.

Breezy northwest winds in combination with the new and fluffy
snowpack will lead to areas of blowing and drifting snow during
the overnight hours. Meanwhile, very cold temperatures will cause
any snow that blows over roadways to stick. The net result will be
localized areas of hazardous travel conditions, especially in open
and rural areas.

If planning to travel tonight, go at safe speeds and leave plenty
of distance between the car in front of you. In addition, bring an
emergency kit that includes extra clothing, and notify someone
where you are going and when you plan to arrive in case you get
stuck.

Recent reports from river ice spotters and river gauges indicate
that some melting of ice has occurred over the last few days, but
isolated areas of heavy river ice coverage continue. Very cold
temperatures this weekend will cause river ice to expand in
coverage. Ice jams will be possible in isolated areas along the
Rock, Fox, Des Plaines, and Kankakee rivers into early next week.
Ice jams may cause rises on area rivers with little warning.

Warmer temperatures may return to the area by late next week, which
could begin a slow melt of river ice.

This outlook means that elevated water levels and potential impacts
are possible, but not yet certain. Persons with interests along area
rivers should closely monitor the latest forecasts.

This outlook may be updated by tomorrow afternoon.
