INDIANA (AP) _ Strong thunderstorms rumbling through northwest Indiana have blown the roof off a home, flipped over a semitrailer and left thousands of customers without power.
 
  Winds up to 60 mph and golf ball-size hail were reported Wednesday night from Gary to Fort Wayne. The National Weather Service says more than an inch of rain fell within 20 minutes at Huntertown, near South Bend.
 
  Volunteer Fire Chief Graham Federico tells The Times a home at Lakes of the Four Seasons lost its roof, but no one was injured. Trees and power lines were down throughout Lake County.
 
  The Northern Indiana Public Service Company reported about 35,000 power outages , most in Lake County.
 
  State police reported two overturned vehicles on Interstate 65, including one semi. Minor injuries were reported.
