The risk of severe weather we've been talking about for a week will arrive this afternoon with all threats possible. During the overnight, the Storm Prediction Center released today's risk for severe weather,

The Chicago area could see strong-to-severe thunderstorms on Sunday, with isolated tornadoes and damaging winds possible.

Nearly 30,000 people remain without power Monday morning after powerful storms with winds as high as 80 miles per hour winds tore through northwest Indiana Sunday, leaving downed trees and damaged buildings and homes in its path.

Hail and massive wind gusts pelted the Chicago area as severe thunderstorms rumbled through Sunday afternoon. The system had prompted a tornado watch covering most of northeastern Illinois and northwest Indiana, but the National Weather Service canceled it by 3:15 p.m. with storms rolling out over Lake Michigan.

National Weather Service weather balloon releases — tracking temperature, pressure and wind speed — have been temporarily suspended in Omaha, Nebraska, and Rapid City, South Dakota, because of staff shortages and reduced at six other sites in the Midwest and Great Plains, according to agency memos.

A tornado warning was issued in northwest Indiana and most Chicago-area counties saw severe thunderstorm warnings on an eventful Sunday afternoon.

The Storm Prediction Center has areas southeast of I-55 in an "Enhanced Risk," this is a level 3 of 5 on their severe risk scale. Locations near and along I-55 are in a "Slight Risk" (level 2 of 5), and then north and northwest portions of Chicagoland are in a "Marginal Risk" (level 1/5).

Dramatic temperature swings and more rounds of serious storms are expected to roil Chicago much of the week, according to the National Weather Service.

Weather experts say to expect storms later Sunday and “seesaw temperatures and chances for severe weather” this week.
