Mount Prospect police and firefighter/paramedics responded about 5:16 PM Saturday to a report of a tree blown down on a house at 1110 Hemlock Lane Mount Prospect, IL. Police and firefighter/paramedics received a report that a tree was down on a house.

Firefighters on the scene reported a tree down on a house, and requested the building department respond to check for structural damage.

A roof was blown off of a brick building in Chicago on South Evans Avenue near 73rd Street. Much or all of the roof was blown into the roadway. No injuries were reported.

Paramedics in Chicagoland were called for several elderly people who suffered lacerations or musculoskeletal injuries from falls when winds blew them over.

Wind gusts of 45 to 60 mph were observed across northern Illinois and northwest Indiana Saturday April 2, 2016.

The peak wind gusts at both Chicago O’Hare Iand Rockford were 54 mph. The strongest wind gust observed over land was 60 mph at Pontiac and over water was 61 mph at the Chicago Harrison-Dever Crib.

Numerous snow showers, at times mixed with graupel, moved over northern Illinois and northwest Indiana through the day. These snow showers with graupel were what the NWS calls convective showers — similar processes to convection…or thunderstorms. The convective snow showers produced brief but heavy snowfall rates, which brought visibility down to zero in some locations. Combined with the winds the convective snow showers brought near white-out conditions.

The skies began to clear about 2 p.m.

Arlington Heights had one significant power outage on the south side Saturday afternoon with a blown transformer at Arlington Heights Road and Seegers Road.
