An Air Quality Alert is in effect for the State of Iowa until 4pm Friday (7/30).  The National Weather Service says smoke from wildfires in the western US is moving into Iowa thanks to northerly winds from a cold front.  Smoke is expected to remain in most of the state through most of the day.  Meanwhile, fine particle levels are expected to be in the Orange air quality index category.  That’s a level that’s considered unhealthy for sensitive groups like the elderly, people with respiratory or heart disease and children.  The Iowa DNR recommends if you’re in one of those sensitive groups, you should limit the amount of time you’re outside until the air quality improves.
