We’re expecting showers today with a high of 64. The rain should continue into the evening, but taper off in the late night hours. `New York City’s new Schools Chancellor has been spending a lot of time in the neighborhood. Tonight the charm offensive continues when Dennis Walcott convenes a town hall at P.S. 20 on Essex Street. Also tonight, the city will detail plans for the East River waterfront between Pike Slip to Pier 35, in an appearance before a Community Board 3 committee. And historic preservation expert Andrew Dolkart will be speaking at the Tenement Museum. More details on these and many other events on our Calendar.
