Cloudy skies this morning, with more rain expected this afternoon, beginning around 1 p.m. Expected high: 54 degrees. Today we’ll have our profile of Allegra LaViola, one of the galleries taking part in this week’s “Third Thursdays” nighttime art event. Also, as Community Board 3 continues to debate the future of the Essex Street Market, we take a look at the historical significance of the quirky 1940 market buildings. And the Festival of Ideas needs your input. We’ll explain. Remember to check out our Events Calendar and “Like” us on Facebook to stay connected to The Lo-Down throughout the day.
