Heavy migration over the northeastern and mid-Atlantic US will mean lots of influx and replacement into our region. Here’s the radar from 7:00pm last night through 5:00am this morning.

While I had expected the winds to turn more northwesterly last night, it appears that they stuck closer to northerly. This is supported by the velocity image which shows most movement heading N->S across the region. Since migration was heavy and widespread, most fall migrant traps across the region should be seeing some new birds today. Cape May is still a good pick since the regional map shows a good movement of birds down the east coast from New England; while interior locations will be good today for both migrant songbirds as well as diurnal raptors.
