Mayor Bill de Blasio and NBC weatherman Al Roker on Monday found closure over school closures and a spat that played out publicly over Twitter earlier this month.

De Blasio appeared on the "Today" show to cut the ribbon on NBC's new plaza in midtown Manhattan. A friendly Roker introduced the mayor.

"We'll get this out of the way. We had a little, little chat about school closings and snow, and we want the best for the schoolkids and our city," Roker said.

"That's right," de Blasio said. "And now look, I think together, letting people know what's going on with the weather, letting people know how they can be safe, that's something we do together."

De Blasio pointed out that snow is coming back to New York in the next few days and presented Roker with a Department of Sanitation hat emblazoned "DSNY."

He invited Roker "to come out and join us for snow clearance."

"I'd love to do it," Roker said. "My dad was a bus driver and he used to drive a snow-clearing bus."

"New York's Strongest," he said, evoking the department's nickname.

Roker had criticized de Blasio via Twitter over the mayor's decision to keep schools open despite a heavy snowstorm on Feb. 13.

He said he had predicted that morning that de Blasio would close schools due to the storm.

"Talk about a bad prediction. Long range DiBlasio [sic] forecast: 1 term," the media personality wrote in his tweet.

De Blasio on Sunday made light of the feud, tweeting at Roker and the "Today" show, "Long-term forecast: sunny."

In subsequent tweets on Feb. 13, Roker had accused de Blasio of putting kids' safety at risk -- including that of Roker's daughter, who attends a city public school -- and slammed the call to open schools in the morning but close them early as lacking common sense.

The mayor later that day at a news conference shot back at Roker, "It's a different thing to run a city than to give the weather on TV."

Roker on air Feb. 14 said his concern was for children's safety, but expressed regrets over his Twitter insults.

"I'm very passionate about the weather," he said.

"I made a prediction that there would be only one term of his administration. I apologize for that. That was a little below the line."
