Today's forecast: tense, icy and awkward!

On the TODAY show Thursday morning -- a month and a half after the departure of co-anchor Ann Curry -- Al Roker made a cutting remark live on the plaza in NYC's Rockefeller Center.

As the weatherman, 57, and Curry's replacement Savannah Guthrie looked on, Matt Lauer interviewed three members of USA's gold-medal-winning rowing team about their victory traditions -- including tossing a teammate into the water.

"The tradition here in New York is you throw her in the Hudson River," Lauer joked.

As Lauer began to wrap up the interview, Roker then decided to chime in with a quip of his own: "Which is different than our tradition, which is to throw one of us under the bus, but that's another story . . ."

Lauer and Guthrie, 40, laughed nervously.

Roker worked alongside Curry, 55, during her 15 years on the show. She was fired back in June after just one year as co-anchor.

A show insider told Us back in June: "Matt Lauer is 100 percent behind Ann leaving," a source tells Us Weekly. In the days leading up to her emotional on-air farewell, Curry and Lauer, 54, "were really icy to each other."
