Give an early hello to summer, why don't ya?

Under clear blue skies with light southwest winds, it hit a high of 80 degrees Wednesday afternoon at Long Island MacArthur Airport, the National Weather Service said.

News 12 Long Island meteorologist Rich Hoffman said the warm conditions will last through the weekend, with humidity levels also climbing.

"With temperatures above normal . . . it will feel like summer," Hoffman said.

On the downside, the state Department of Environmental Conservation and state Department of Health issued an air quality health advisory for Long Island and New York City, to be in effect Thursday from 10 a.m. through 10 p.m.

Such advisories are issued when there are concerns over pollution levels.

"People, especially young children, those who exercise outdoors, those involved in vigorous outdoor work and those who have respiratory disease (such as asthma) should consider limiting strenuous outdoor physical activity when ozone levels are the highest (generally afternoon to early evening)," the DEC said in a news release.

With the warmth and high humidity also comes the chance of rain, including thunderstorms.

Hoffman said clouds move in Wednesday night and linger Thursday and Friday as daytime highs for both days reach into the low to mid-80s.

Showers or thunderstorms are likely Thursday into the nighttime hours, and again Friday toward evening.

Overnight Wednesday into Thursday morning there's a chance for patchy fog as lows drop into the low to mid-60s.
