It was a nice night for a “white” wedding — or an engagement, at least.

Paul Schwartz’s plans to propose to his longtime girlfriend, Jaclyn Quinn, last night during a romantic stroll in Central Park were almost iced by the snowstorm that struck the city.

The Astoria, Queens, lovebirds went to see the Christmas Tree in Rockefeller Center, when Schwartz coaxed his chilly girlfriend to go to the Park.

“The storm almost ruined my plans, but I was able to convince her,” said Schwartz, who works for the Mets.

Quinn didn’t have to think twice before saying yes.

“It was really beautiful,” she said.
