Raging wildfires in the Western United States are having some impact on Iowa as the ash blows east. Brian Button of the Iowa Department of Natural Resources Air Quality Bureau tracks the stuff that floats in Iowa’s air.He says the computer models and monitors show a small amount of the ash in Iowa. Button says the particles that do make it here will make the sunsets appear brighter.He says the scattered particles in the air act as a device to scatter the light. The National Weather Service predicts the smoke from the wildfires will get worse in Iowa in the next few days.
