Birds were on the move over the Northeast last night. The radar loop is from sunset last night through 8:30am this morning, and shows a moderate amount of migration over New Jersey. There is some anomalous propagation present, due to the significant difference in earth and air temperature after sunset (resulting in temperature inversion) but the velocity still shows objects moving across the radar at speeds +10-20kts faster than the prevailing winds (ie. birds).
Hopefully Bill gets a good day up on the hill…wish I could be there!
