Details for the city’s first We Overcame Winter celebration were released Thursday as weather forecasts promised a Sunday hitting 60 degrees or higher:

The free party is to be held from noon to 3 p.m. Sunday at Riverside Press Park at Memorial Drive and River Street, said organizers of the spontaneous celebration of spring thought up by citizens.

The idea: citywide dance party meets a beautiful day at the park with friends, family and games and entertainment for all ages. Residents are encouraged to bring things to do, from frisbees to musical instruments.

“We are ready to shake off the winter blues and celebrate,” said a press release from organizers and Cambridge Arts Council. “On Sunday we’ll come together as a community to celebrate the fact that we survived this especially tough winter.”

The event has been in the works for weeks, just waiting for the perfect Sunday, organizer Karin Freed said. It was thought up at the tail end of a stubborn, record-breaking season, when 110.6 inches of snow fell through March 5 and frigid temperatures and rushing winds lingered even longer, sustaining the suspense of when temperatures would finally be right.

“One of the best parts about living in a city like Cambridge is that when you have an idea for something like this, you can actually make it happen. I first mentioned my idea for WOWcambridge! on Facebook a few months back, and before I knew it, I had a city councillor and the Cambridge Arts Council helping me make it a reality,” Freed said, referring to city councillor Nadeem Mazen. “I can’t wait for the whole city to spend the day together outside, breathing one giant sigh of relief that spring is finally here.”

Other event partners include Ken Field and the Second Line Social Aid & Pleasure Society Brass Band, and children’s play organizer Knucklebones.

Julie Barry, director of community arts at the Arts Council, said she was thrilled to partner with WOWcambridge! on “this wonderful initiative in celebration of community, arts and spring.”
