According to the National Weather Service, about an inch of rain fell in 20 minutes in Riverwoods, east of Buffalo Grove. Much of downtown Arlington Heights was without power. The Chase Bank drive thru was closed early and several restaurants had lost power for Friday night.

As the storm approached, students at Thomas Middle School and South Middle Schools, were moved to their homerooms and the gym just before the dismissal time of 2:45 p.m. and were not allowed to leave the buildings until the storm passed. Students at John Hersey High School were also kept inside the school building until the storm passed. An area along South Street near South Middle School was especially hard hit. A well-cared-for Linden tree at the northwest corner of Evergreen Avenue and South Street was uprooted and fell from west to east. The Linden tree fell into power lines and caused a power line to arc for a prolonged period on South Street just west of Evergreen Avenue. The arcing electricity melted and burned asphalt and heat-drilled a 2-4 foot hole in the street. Three ComEd crews de-energized the lines, worked to trim branches away from downed lines, discarded the downed lines, and installed news lines. Then they restored electricity, and moved on to their next assignment.

At Haddow Avenue and Hawthorne Street at least two trees had severe damage. One tree broke at the base, bringing down the whole tree along with a bald-faced hornets’ nest. Neighbor called public works to warn them about the nest. A public works crew responded with spray foam to kill the hornets in the nest before a tree removal crew would arrive later. Another tree nearby brought power lines across Hawthorne Street. A large branch fell across Hawthorne Street with power lines also across Hawthorne Street. With barricades at the street, several motorists drove up on the corner parkway lawn on top of downed power lines to get around the barricades.

The neighborhood just north of Recreation Park to about Euclid Avenue and west of Douglas Avenue was especially hard hit with large branches, whole trees and half of mature trees down from cracks or uprootings. East central Arlington Heights near Forrest Avenue and near Euclid Avenue and Gibbons Avenue also had several trees damaged. Areas near Stratford Avenue and Gibbons Avenue south of Euclid Avenue were peppered with small tree debris.
