The winds were light last night; more easterly to the south and more southwesterly to the north, creating an interesting signature across the radar.

So the northern half of New Jersey experienced the bulk of the migration last night, with birds traveling in a typical SW->NE direction over Sandy Hook and into Manhattan and Long Island, NY. Sandy Hook and Garret Mountain, therefore, should be the best bets for new arrivals this morning.
Further south, though, migration was on a more S->N trajectory, although not as prominent as it had been in previous nights, when east winds had been stronger. Some birds can actually be seen crossing between Lewes, DE and the Cape May peninsula last night, unlike the night before. Still, the bulk of migration in the south entered New Jersey well north on the Delaware Bay shore such that any appreciable migration activity will be most likely in those locales.
