Frames are every 1/2 hour for reflectivity and velocity, and every hour for the regional composite. Click on the thumbnail to view the full-sized animation.
On the regional composite you can actually see a large mass of birds (mix of green and dark blue signal) making its way into the region from the NNW. This is also evident on the Fort Dix reflectivity image, and is confirmed by the speed and direction on the velocity image. Birds were both entering and leaving the state last night, with a good push of birds downstate from the north as well. Observations across the state over the last few days indicate that the majority of current migrants are less affected by the westerly component to the wind, and seem to be correcting for the cross winds during nocturnal flight. For this reason I’m suggesting that inland sites, as well as coastal ones, should be birdy this morning. It will be interesting to compare composition at both locations to see which species or individuals (such as first-year birds) appear to be more affected than others. I look forward to your comments!
Good Birding
