Pro

The freeze line across the stations upstream of this region, station by station, so you see shallow water locking up before the birds arrive on it.

Pro

Last night's NEXRAD read on whether birds actually moved: how much lifted off after sunset, which way it tracked, and how fast it flew under its own power once the wind at that altitude is subtracted out.
