Migration Weather Forecast

Thursday, Friday, Saturday & Sunday Nights

Right now the mid-Atlantic is under the influence of a strong high pressure system, bounded to the south by a low over Florida and associated front creating strong ENE flow across the southeastern US. This front has effectively become a barrier to any birds in the southeast that might want to migrate north. Over the mid-Atlantic, though, the high pressure system has set up a light to moderate south/southwesterly flow, which will trigger several nights of migration from the Carolinas and Virginia all the way up into the northeastern US. Clear skies are on tap until the end of the weekend, and even then, we're not expecting much. Therefore migration will be heavy and well dispersed across the landscape.

Birding Forecast

Friday, Saturday, Sunday & Monday Morning

Right now the birding forecast is looking pretty predictable... of course, all of this can change in a couple of days. Winds are forecast to be light to moderate out of the south/southwest, and coupled with clear skies, we should see some widespread migration across the mid-Atlantic throughout the weekend. Because no strong crosswinds nor heavy precipitation are forecast, you can expect the best birding conditions to be found in established spring migrant traps such as Higbee's Beach, Cape May (NJ; best on WSW winds), Belleplain State Forest, Garret Mountain, Sandy Hook (best on WSW winds) and Central Park (NY).
