Heavy precipitation over NJ appears to have precluded any nocturnal migration over NJ last night, despite the prevailing southeast winds. Otherwise migration was light in the surrounding region. Here’s the radar from sunset last night through 5:00am this morning.

Light migration was apparent over VA, Washington DC, western PA and NY, all of which was on a strong SE->NW trajectory. With little movement over NJ, expect conditions to remain stable from yesterday across the interior part of the state with some birds shifting locally to find better foraging habitat. Otherwise expect less birds along the coast as they head inland on SE winds, while those of you watching the ocean may be treated with the odd tern, phalarope, or a continuation of the jaeger show which has been keeping us quite entertained here in Cape May.
Looking ahead, it appears as if the southeast wind will continue at least through Thursday, but then should turn more southerly as we enter the weekend, just in time for the NJ Audubon/CMBO Cape MAYgration festival beginning today and running through next week! I’ll be leading a workshop (Fri and Sat) on using radar and weather to predict birding conditions, and there are plenty of other great forums, guided walks, and speakers to satisfy birders of every level and interest.
