Tornado Watch for entire Chicago area as severe storms race east; tornadoes, funnel clouds reported northwest
A tornado watch has expanded to the entire Chicago area as two rounds of severe storms that could spawn twisters and bring hail, flooding and straight-line winds up to 70 miles per hour race towards us from the west Friday evening.
A Tornado Watch has been issued for Boone, De Kalb, La Salle, Lee, McHenry, Ogle and Winnebago counties until 10 p.m. and for Cook, DuPage, Grundy, Ford, Kane, Kankakee, Kendall, Lake, Iroquois, Livingston and Will counties until 11 p.m.
A Tornado Warning is in effect until 8:45 p.m. for parts of LaSalle County. Another Tornado Warning is in effect until 9 p.m. for Lake County. A third Tornado Warning has been issued until 9:15 p.m. for parts of DeKalb and LaSalle counties.
A Severe Thunderstorm Warning is in effect until 9:15 p.m. in parts of DeKalb, LaSalle, and Lee counties. Another Severe Thunderstorm Warning has been issued for Cook and Lake counties until 9:30 p.m. A third Severe Thunderstorm Warning has been issued until 9 p.m. for Kane and McHenry counties.
A ground stop is in effect at O’Hare International Airport until 9:45 p.m. due to the storms.
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.
A tornado has been reported in Lena, Illinois, about 47 miles west of Rockford. That tornado reportedly damaged both the high school and elementary school, passing over while students were still inside. Law enforcement are warning people to stay away due to intensive storm damage.
In Machesney Park in Winnebago County, people snapped pictures of funnel clouds as the first round of storms raced through.
The second, later round of storms will arrive in a line that will impact the entire Chicago area, producing straight-line winds that could reach up to 70 miles per hour. They’re expected to arrive in the Chicago area around 8 p.m. and last for several hours. Storms should be tapering off by midnight.
The highest risk for tornadoes is in this later round of storms, in the western suburbs, between 8 p.m. and 10 p.m.
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.
A Flood Watch is also in effect for the entire Chicago area, as storms will bring 1 to 2 inches of rain 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.
