Tornadic Conditions: Witnessed by Pro Radar Observers and Citizens Who Saw Orange and Purple Storm Clouds in Schaumburg

Storm clouds while Tornado Warning in effect, and storm damage in Schaumburg and Mount Prospect (full screen view shows orange tints coming through clouds that were caught on video in Arlington Heights).

The National Weather Service issued a Tornado Warning for northwest Cook County about 2:18 p.m. Sunday effective until 3:00 p.m. as doppler radar indicated a severe thunderstorm capable of producing a tornado with a cell that developed over West Chicago — southwest of Arlington Heights and surrounding suburbs. Doppler radar can indicate rotation in a thunderstorm cell. By the time the storm approached Rolling Meadows the storm dissipated and the Tornado Warning was canceled early — at about 2:42 p.m.

In the northwest suburbs, the storm did the most damage in Schaumburg near Schaumburg Road and Salem Drive. Some small trees were ripped up or broken at the base near Schaumburg Fire Station 51 and the Schaumburg Police Department.

On the east side of Volkening Park more trees were damaged. Some tree branches smashed into townhouses, and caused minor roof damage and a broken window. On the east side of Salem Drive, just north of Schaumburg Road, a large tree was uprooted. The relocated trunk pulled up the ground and exposed some underground cables and wiring. Firefighters responded and reported that the cables were data cables and telephone cables — producing no hazard.

Witnesses to the storm near Volkening Park reported seeing beautiful orange and purple clouds that turned dark before the storm hit. Tornadic conditions involve a deflection down of the jet stream overhead, which brings some unusual lighting down the tall tops of thunderheads.

In Mount Prospect a tree was uprooted on Pine Street, just north of Central Road. The large tree landed on two vehicles.

No injuries were reported. Some roadways were temporarily flooded.
