Wind Advisory for Much of Northern Illinois in Effect 6PM Wednesday to 3AM Thursday; Additional Storms Possible

TODAY SUNRISE: 7:18 AM SUNSET: 4:24 PM

Chicagoland weather radar shows a thunderstorm line from Peoria to the northwest tip of Illinois at about 5:25 p.m. The fast-moving (54 knots) thunderstorm line is moving northeast and the southern tip, if it stays intact, would likely pass through the northwest suburbs within 60 to 90 minutes (6:30 p.m. to 7:00 p.m.). At least one computer model forecasts weakening of severe weather east of I-39. The radar image has shown slight weakening in a 30-minute period observed. Also the tops that would be headed toward Arlington Heights are only 18,000 feet. The thunderstorm risk ends by 10:00 p.m. but high damaging winds are possible until about 2:00 a.m.

A Tornado Watch is in effect until 8:00 p.m. for several counties in northwest and western Illinois including the Peoria.

Satellite images show two main areas of clouds — one in eastern Illinois and one in west-northwest Illinois.

Peak winds with gusts of about 51 MPH are expected about 10 p.m.
