A series of weak fronts are moving across the country bringing with them southerly winds to their east, and northerly winds to their west. This has meant a mix of migration across the Eastern Flyway, depending on where the frontal boundary falls before sunset. Currently there is a front bisecting the mid-Atlantic from the northeast to the southwest, causing migration conditions in western New York and Pennsylvania but not along the extreme east coast from Virginia up through eastern New York.

Another cold front is forecast to cross the region between Tuesday and Wednesday, and high pressure is forecast to build in behind it which would set us up for another big push of migrants. If the wind forecast for Wednesday night is correct (for strong northwest winds over the Great Lakes and west over Pennsylvania and southern New York), we could see some interesting diversity into the coastal states by Thursday morning.

Good Birding
