I wish I had more time to comment- but I’m late for some morning birding! Here’s the radar from sunset last night through 6:30am this morning.
Frames are every 1/2 hour. Click on the thumbnail to view the full-sized animation.
Check out the trajectory across the radar (using the velocity loops), the intensity (using the base reflectivity), and the extent (using the regional composite), and you’ll see that migration was moderate and typical of a spring flight across most of the mid-Atlantic. These conditions are good for the tried-and-true spring migrant traps, as well as anywhere that experienced rain in the early morning hours. Get out there and see what’s around, and make sure to come back and let us know what you saw!
Good Birding
