Winds turned ESE yesterday, as the latest low-pressure system and cold front approached from the west. This resulted in light to moderate migration across the Eastern and Mississippi flyways last night, with the heaviest migration occurring well to our south along the Gulf Coast and Florida Peninsula. Migration over New Jersey, however, was quite low an restricted to the western half of the state. Here’s the radar from 7:00pm last night through 5:00am this morning.

Easterly winds clearly favored inland locations last night, as no birds appeared to be moving into or out-of the eastern half of New Jersey during the last twelve hours. Based on this, I wouldn’t expect much in terms of noticeable change, except maybe at spring migrant traps along the Delaware river and into the northwestern portion of the state.
With southeast winds forecast againÂ tonight, we could see a second push of birds into the region by tomorrow morning. Most of this dependsÂ on the intensity of the precipitation associated with the passing cold front. Either way, easterly winds shouldÂ favor inland migrant traps on Monday morning.
