Trans-Gulf migration into the Texas coast was followed by widespread nocturnal migration across most of the country last night. Notable exceptions were the areas under the control of high pressure such as New England and the Four Corners region of the Southwestern U.S. Migration was heaviest up the central U.S. from Oklahoma to southeastern Wisconsin, and east to the Ohio Valley and Appalachian Mountains.

Last night was the moment we’ve all been waiting for: the levee has finally broken! Low pressure over the Great Lakes brought a series of frontal boundaries over Point Pelee last night setting up a strong southwesterly flow across the forecast region. While we would have preferred a more southerly flow (as had been forecast in previous days), the magnitude of migration to the south means that plenty of birds were over Pelee at daybreak this morning.
Looking at both the Detroit and Cleveland radars it is clear that migration density was high and birds were moving fast with a strong tailwind. The velocity images indicate SSW->NNE movement across the region, and little precipitation was present to knock birds down last night. This means birds will be widespread across the forecast area today with excellent concentrations only at tried and true spring stopover hotspots. Point Pelee will be good today, as will Rondeau and Long Point. Warming temperatures today should bring more birdsong to the region as well.
In a few words: GET OUT THERE AND BIRD!
