Seven hundred and two days and counting.
That's the stretch, as of Monday night, of no-90-degree days at Long Island MacArthur Airport.
If that holds through the night of June 30 it will mark the longest stretch of no 90s in the three decades the National Weather Service has maintained the Island's official records at the airport.
Of the coming days, Tuesday has the best chance of hitting 90, with the National Weather Service forecasting a high of 89 at the airport, as of Monday night.
Weather service meteorologist Jay Engle said, "It's right on the fence" of reaching 90 degrees Tuesday. But Bill Korbel, meteorologist with News 12 Long Island, said, "We are not going to see 90 tomorrow [Tuesday] at MacArthur Airport. . . . Maybe in towards the Nassau-Queens line it could get close, but the ocean influence and some showers and thunderstorms will keep that from happening elsewhere on the Island."
The longest 90s-free period lasted nearly two years -- or 709 days -- from July 6, 2003, to June 13, 2005, according to the Northeast Regional Climate Center, based at Cornell University in upstate Ithaca.
The last time the airport saw 90 was July 20, 2013, when it registered 90 degrees on the nose.
Since then, the highest was 89 on June 18 last year, said Jessica Spaccio, a climatologist with the center.
Behind this dearth of 90-degree days, said Brett Anderson, senior meteorologist with AccuWeather, is a persistent weather pattern that frequently finds a ridge over the West Coast that leads to the jet stream's dipping down into the eastern United States, delivering cooler air from Canada.
Though MacArthur is the official marker, other spots on the Island could have hit 90, said Joe Pollina, a National Weather Service meteorologist based in Upton, pointing to areas closer to the city. Both Kennedy and LaGuardia airports saw highs Sunday of 90, he said.
Looking ahead to the next several days, weather service meteorologists forecast highs in the upper-80s Tuesday, creeping down to the 70s by Sunday.
Apart from Tuesday's possibility, a longer view out to at least July 4 shows little chance for crossing the 90-degree line, Anderson said. "I see nothing to show the stretch of no-90s would end anytime soon."
