INDIANAPOLIS (AP) _ A long line of thunderstorms that could spawn straight-line winds with speeds comparable to a tornado is making its way toward Indiana.
 
  National Weather Service meteorologist Marc Dahmer says the massive storms building in Iowa are expected to push into northwest Indiana about 8 p.m. Wednesday, then bear down on the Indianapolis area late Wednesday night before continuing east.
 
  Dahmer says the storm front could create a huge, long-lasting mass of storms called a derecho, with straight-line winds of up to 70 mph. 
 
  He says a derecho’s winds can be comparable to those of an EF-1 tornado.
 
  The Storm Prediction Center in Norman, Okla, says the risk of severe weather in Chicago and Indianapolis is roughly 45 times higher than on a normal June day.
