Current winds at all altitudes over the Delmarva and south NJ are out of the SW while only upper-level winds over the most northern part of the state (Southern NY, really) remain out of the NW. Migration has already begun and WSB participants should expect migrants throughout the region tomorrow AM. Coastal sites will see good density and diversity, as will interior migrant traps such as Garret Mountain. See the pervious forecast for more detail as everything still holds. Good luck and good birding!!
