Monday will be a good day to stay inside as an Air Quality Advisory Day is predicted for Lexington.
High temperatures and sunshine mean that ground-level ozone and particulate matter are expected to be high. The expected 106 reading on the air quality index scale means the air could be unsafe for active children and adults, and for others with chronic health conditions, such as asthma. Air pollution generally is higher in the last afternoon and early evening.
Charles Schaub, a senior transportation planner with the city, said that this is the first alert this year. There were none last year, he said, but there were eight in 2007.
