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.
Most of the base reflectivity signal present last night was either anomalous propagation (caused by the temperature inversion after sunset) or objects moving with the wind (south –> north; pollen, dust, etc.). These can be determined by looking at the velocity image, which only shows a small amount of movement from the north –> south. As for the region, the breaking point between migration and non-migration was around North Carolina, such that all points south of NC along the eastern flyway experienced moderate to heavy levels of migration. This should mean that most of the birds that entered our area over the weekend will still be around, waiting for you to find them!
Good Birding, and happy Labor Day.
