Here’s the radar from sunset last night through 5:30am this morning.

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.

Upper level winds last night were out of the NW, while surface winds remained light and variable, which could explain why migration was light to moderate and appeared concentrated at lower altitudes. Birds appeared on the radar just after sunset, with density peaking around midnight, and tapering off soon thereafter (most birds had landed well before sunrise). Movement was in a SW–>NE direction, and no precipitation was present to cause fallout conditions. The best bets today will be spring migrant traps such as Garret Mountain, Sandy Hook, the Delaware Bay shore, and possibly Cape May (given the more westerly wind component in South Jersey), but given the “light to moderate” levels of migration, don’t expect huge numbers at any location… right now we’re striving for quality over quantity!

Good Birding
