Today, look to the sky.

With the familiar roar of planes and fighter jets coming and going from Long Island MacArthur Airport in Ronkonkoma and Republic Airport in Farmingdale, more than a dozen superstars of the stratosphere will be en route to Jones Beach for the FourLeaf Credit Union Air Show Saturday and Sunday.

Organizers boast that this year will have the most military performers in the show's 21-year history as it pays tribute to Memorial Day. Performances run from 10 a.m. to 3 p.m. both days. The show is free, but Jones Beach State Park charges $10 per vehicle.

Performers from each branch of the military include the headliner U.S. Air Force Thunderbirds, F-35 demonstrations by the U.S. Navy and Marine Corps and the U.S. Army’s Golden Knights paratroopers. It will also feature civilian stunt planes and World War II Warbird Thunder acrobatic planes from the American Airpower Museum in East Farmingdale.

“We can celebrate the individuals that gave their lives to their countries by thanking them, by honoring them,” said George Gorman, State Parks regional director for Long Island. “So, this has turned into an air show on Memorial Day weekend that is so patriotic and enjoyable by everyone.”

The show is expected to attract 250,000 people over the weekend after drawing more than 30,000 people on Friday.

Though Friday’s rehearsal show stalled early due to drizzly cloud cover, the weekend forecast looks more promising.

The forecast calls for mostly sunny skies Saturday, with a chance of isolated showers in the afternoon. Temperatures Sunday could reach the mid-60s, according to the National Weather Service.

Organizers are urging beachgoers to arrive early Saturday and Sunday. In past years, when the show reached capacity, authorities have closed parkways and roads surrounding Jones Beach.

State Park and air show websites will announce if parking fields are full or if the show reaches capacity.
