Two rounds of storms in Chicago area bring tornado watches, warnings; flood risk through the morning

A tornado watch remains in effect for part of northwest Indiana as the threat of tornadoes from two rounds of severe storms has otherwise ended for the Chicago area.

A Tornado Watch is in effect until 2 a.m. Saturday for La Porte County.

A Severe Thunderstorm Warning is in effect in La Porte County until 12:30 a.m. Saturday.

The storms also prompted multiple tornado warnings and watches and severe thunderstorm warnings in northern Illinois, but all of those have since expired.

The first round of storms raced across northwestern Illinois, but curved north before they reached the Chicago area and veered off into Wisconsin instead of into the Chicago area. The second of storms reached the Chicago area Friday evening, prompting multiple tornado warnings that have since expired.

This line of storms could cause severe damage from high winds. Brief spin-up tornados, flash flooding and hail are also risks.

Thunderstorms could drop anywhere from one to three inches of rain, again inundating our already-soaked ground and raising the overall flood risk, as well as creating potential for some flash flooding.

Storms should be tapering off by midnight.   

A tornado was reported in Lena, Illinois, on Friday afternoon about 47 miles west of Rockford. That tornado reportedly damaged both the high school and elementary school, passing over while students were still inside. No deaths or major injuries were reported.

In Machesney Park in Winnebago County, people snapped pictures of funnel clouds as the first round of storms raced through.

Flood Watch is also in effect until 5 a.m. Saturday for the entire Chicago area, as storms will bring 1 to 2 inches of rain for most places, and as high as 3 inches in some areas.  

A Flash Flood Warning also is in effect until 2 a.m. Saturday for Boone, Lake, and McHenry counties.

More than 51 million people are under the threat of severe weather tonight from Texas to Wisconsin. In Illinois, the water level of the Des Plaines and Fox rivers are already high and those communities are already dealing with flooding, a situation Friday night's storms will only worsen.

The National Weather Service has issued a Flood Warning for areas along the Fox River until further notice. 

ComEd said it is taking proactive steps ahead of Friday night's weather, especially with such high winds expected. They said they are assessing conditions and staging crews based on the forecast to respond to reported power outages as quickly as possible.
