Partly cloudy this morning, with thunderstorms developing in the afternoon. Look for a high of 81.This evening, Community Board 3 holds its monthly meeting at P.S. 20. A different kind of entertainment takes place several blocks away: the songwriter slam is back at the Nuyorican Poet’s Cafe. Today, we’ll have more on the aftermath of that incident in Columbus Park, in which a 64-year old man was arrested by officers from the 5th Precinct. And we’ll take a look at a new participant in the Seward Park redevelopment talks, an organization called the Project for Public Spaces.
