An isolated severe storm possible over the next few hours into NW IL, with watch issuance unlikely. If a severe storm occurs in Lee, Ogle or Winnebago, main threat would be hail and damaging wind gusts
Isolated to widely scattered thunderstorms are possible this afternoon and evening, basically west of a line from Streator to Aurora to Lake Villa. This is the area that appears to have the greatest risk of a strong to possibly severe thunderstorm or two. As storms move eastward this evening, look for a weakening trend with a much lower risk of thunderstorms south and east of I-55 and into northwest Indiana.
