NOTE: The threat of fierce winds, severe thunderstorms and large hail has since diminished. You can find the latest information from the NBC 5 Storm Team here.
Residents are being urged to seek shelter as severe weather threatens several communities in the Chicago area.
Several severe thunderstorm warnings have already been issued in LaSalle and Grundy counties, with the storms churning to the northeast at 30 miles per hour.
Those warnings will last until 3:45 and 4:15 p.m., respectively, with wind gusts in excess of 50 miles per hour and large hail possible.
Forecasters are warning residents in northwestern Grundy County and east-central LaSalle County to seek shelter, as quarter-size hail could damage cars and could cause injury to those caught outside in the storm.
Most of northern Illinois and all of northern Indiana are currently at a “marginal” risk of severe weather, with “brief tornadoes” possible in areas near Interstate 80, according to officials.
