An air quality alert has been issued for Wednesday.

Here it comes, lovers of summer. Warm and humid conditions are expected for the coming days, with highs to near 90 on Wednesday, the National Weather Service says.

An air quality alert has been issued for Long Island from 11 a.m. to 11 p.m. Wednesday, meaning an elevated level of the pollutant ozone is expected, the service said. Those who could be especially impacted are the very young and anyone with respiratory issues, such as asthma or heart disease, the service said in its alert.

Wednesday is looking at sunny skies with highs of around 89 at Long Island MacArthur Airport, with a tilt into the 90s not out of the question, said Jay Engle, weather service meteorologist based in Upton.

Should it arrive, this year’s first hit of 90 or above would be coming a little on the late side, with June 17 the average day to see the temperature move up and out of the 80s at the airport, said Samantha Borisoff, climatologist with the Northeast Regional Climate Center based at Cornell University. That’s based on data the weather service has from 1984 to 2015 for the airport.

The last time the airport hit 90 or above was Sept. 9, when 91 degrees registered, she said.
