2nd UPDATE, 11:15 A.M.: The nearly sold-out Jake Gyllenhaal/Ruth Wilson 70-minute two-hander Constellations also has jumped on the inclement-weather discount bandwagon. At Tuesday’s 7 P.M. and Wednesday’s 2 P.M. matinee, select seats will be available for $100 when you say the secret passwords “Winter Weather Discount” at the box office, or via TelechargeOffers.com by using code CLSNW15, or by calling 212-947-8844.

UPDATE, 10:15 A.M.: Shows are beginning to promote “snow day” specials. Honeymoon In Vegas, at the Nederlander Theatre, is hawking $79 orchestra and front mezzanine seats to gamblers who mention the “storm special.”

There’s snow business on Broadway tonight as most shows return to their normal schedules while NYC emerges from the Blizzard That Wasn’t. The exception is Disney’s two big family shows, Aladdin and The Lion King, which will take a second night off, according to company spokesman Dennis Crowley. Disney decided Monday to cancel the second night in deference to folks traveling with kids through the bad weather which has hit areas outside book of mormonManhattan much stronger than Gotham herself. As for the rest, with the Street already socked by the usual January blues and several big-name closings, the decision to return to business was welcome. But it’s probably a great night for intrepid theatergoers to get on the no-show lines for The Book Of Mormon, Bradley Cooper’s The Elephant Man and Jake Gyllenhaal and Ruth Wilson’s Constellations, whose SRO status might be breachable this evening.
