Kingsboider note: Although bird migration is a tough thing to explain, basically birds need the tailwinds to propel their flight and further their distance to facilitate or maximize thier efficient body fat metabolism. Hence south winds in spring, north winds in fall for favored flight. Weather systems are factor in how it stops birds in their tracks or divert their plans as well as how good was the weather the night before, one hour after sunset for birds to orient themselves to the setting sun. There aren't any absolute theorems so I don't like predicting.I go out every day anyway ( if i was retired ;)> ) during the peak period.

From the side bar menu ------> "Bird migration forecast" a fellow named Dave in Cape May has a blog that tracks the radar tracking of migration and prognosticates daily migration trends. Good to check the weather and wind direction during the evenings at dusk to supplement his blog called Woodcreeper.
