There were a few flurries of snow on Friday, but not enough snow stuck in the city to make even a single snowball and throw it at someone who doesn’t believe in global warming. This weekend, there is a very small chance of snow (10% chance for flurries on Saturday night), but mostly the weather just looks frigid and windy.

There’s plenty to keep you occupied in the neighborhood, though, and you can find events on our calendar, including “Spacefest” at the Museum of Natural History all day on Sunday. Also, the Jewish Film Festival just started at the Film Society of Lincoln Center and you can get tickets here.

One big event this weekend is being put on by the folks at Occupy Wall Street, many of whom have stuck around in the city and live in Upper West Side churches. On Sunday at 6:30, the group will gather on the steps of the Cathedral of St. John the Divine on 112th Street and Amsterdam Avenue and march to Riverside Church on 120th Street and Riverside Drive. At Riverside Church, Patti Smith and Steve Earle will play music, and Yoko Ono and hip hop impresario Russell Simmons will give speeches.

Various institutions are putting on events to celebrate Martin Luther King, Jr. On Sunday, the Society for Ethical Culture on 64th is hosting a panel of activists representing different perspectives on Occupy Wall Street at 11:15 a.m. The JCC is hosting a Day of Service in the neighborhood starting at 10 a.m. on Monday, as well as a blood drive. Central Park is hosting special tours of Seneca Village, the African-American village that was razed to make way for Central Park, at 12:30 and 2:30 on Monday. And Symphony Space is hosting a free concert on Monday at 6:30.

Or if all of that sounds like way too much activity, there’s always the Giants game at 4:30 p.m. on Sunday. Go Blue!
