Partly cloudy today with a high of (brrrrr) only 33 degrees. 15-25mph winds will make it seem even colder. Last night, backers of a Chinatown Business Improvement District cleared a major hurdle — winning the endorsement of Community Board 3’s economic development committee. We’ll have a complete wrap-up later today. Tonight in the neighborhood, Kenneth Jackson (the Encyclopedia of New York City) makes an appearance at the Tenement Museum. Over at the Educational Alliance, it’s the opening of “Upcycled,” an exhibition featuring works created from plastic and consumer waste. Check out our Calendar for more events happening on the LES.
