‘Potentially dangerous’ storms could hit Chicago with damaging winds and risk of tornadoes – NBC Chicago

The Chicago area remains at risk for severe weather Tuesday night, with the National Weather Service warning of the possibility of damaging wind gusts and the threat of tornado development late in the evening.

According to a hazardous weather forecast released Tuesday afternoon, NWS officials warned of an “elevated tornado risk” in association with the storms, which are expected to move through Iowa and Missouri before crossing the Mississippi River into Illinois this afternoon. .

Those storms could “overtake” the front heading into the region, robbing them of some fuel, but they are expected to retain their organization and hit the area with a variety of severe weather threats.

According to officials, these could include the development of tornadoes and wind gusts of more than 75 miles per hour in some locations.

The Storm Prediction Center still has all of northeastern Illinois and northwest Indiana at “enhanced” risk for severe weather, the third of five categories used to estimate the probability of severe storm development.

The SPC estimates there is approximately a 10% chance that parts of Chicago’s western suburbs, including McHenry, DeKalb, Kane, LaSalle, Kendall and Grundy counties, could see a tornado form within a 25-mile radius. . That chance drops to 5% in Lake, Cook, DuPage and Will counties, with a non-zero chance of tornadoes occurring elsewhere in the area.

The greatest risk of tornado activity exists along and west of Interstate 39, although tornadoes could form anywhere around the area.

The biggest threat is wind gusts, some of which could exceed 75 miles per hour. The SPC’s current estimate indicates a 30% chance that residents will experience wind gusts greater than 50 miles per hour within a 25-mile radius of their location.

The timeline for storm activity is between 7 p.m. and 1 a.m., according to officials, and colder temperatures will arrive behind the front as it moves.

Even if severe storms don’t impact specific areas, winds could still gust to 40 to 50 miles per hour, officials say.
