Severe weather threatens Chicago area with ‘all weather hazards at play' including hail, tornadoes

As severe weather and tornado watches threatened the Central Plains Tuesday morning, waves of strong to severe storms were expected to move into the Chicago area Tuesday afternoon and evening, the NBC 5 Storm Team said.

According to NBC 5 Meteorologist Alicia Roman, Tuesday during the daytime hours was expected to remain dry. High temperatures in the afternoon were expected to reach into mid-70s, but mid-60s along the lake.

By around 4 p.m. however, rain chances were expected, with an active weather pattern ramping up between 5 p.m. and 11 p.m.

During those hours, all of Northeast Illinois will be under a "slight" risk of severe weather, which ranks as level two of five on the Storm Prediction Center's five-level scale. Northwest Indiana will be under a "marginal" risk, which ranks as level one of five.

At that time, "all weather hazards will be at play," Roman stressed, including heavy rainfall, damaging wind gusts of 60 miles per hour or more, large hail and possibly even a tornado.

"The threat for a tornado is low, but it isn't zero," Roman added.
