Spring, er, winter, is here at last

WINTER to spring: Flake off.

The snow refused to call it quits Monday as 3 inches fell across the city, disrupting commutes, grounding flights and postponing the Yankees’ home opener.

According to Port Authority officials, 91 flights were canceled and 113 delayed out of LaGuardia Airport. Newark saw 22 cancellations and 110 delays and JFK axed 26 flights, with another 74 stalled by the flakes.

Snow began sticking at Yankees Stadium in the Bronx at 5:30 a.m. The Bombers were set to take on the Tampa Bay Rays at 1:05 p.m., but the storm put a stop to that. The teams will make up the game at 4:05 p.m. Tuesday, with gates opening at 2 p.m.

The storm, which swept from Ohio up to the Northeast, left a mix of slush and snow in the city, with only about an inch sticking in colder locales.

National Weather Service meteorologist David Stark blamed a string of back-to-back cold fronts from Canada for the lingering wintry feel. The last time the city saw April snow showers was in 2006, according to the meteorologist, and it was less than an inch.
