Upper level low could cause showers & storms to develop overnight into early Tue mainly S & E I-57. Upper level low will move overhead aft, & therefore some shower or storm development aft, along I-57 eastward corridor, with maybe another lower chance along the I-39 corridor. pic.twitter.com/bLJu3UXNhY— NWS Chicago (@NWSChicago) July 30, 2018
