Upper Midwest and Northeast
Northerly flow and slightly cooler temperatures following the passage of a cold front brought moderate to very heavy flights to the Midwest and Northeast on Friday and Saturday nights. Following the passage of this front, high pressure returned to the region and quieted the movements substantially by Sunday night. Another frontal passage through the region brought moderate to heavy flights in the Midwest and mid Atlantic on Monday and Tuesday nights, with the extent of these flights reaching the coast by Wednesday night. Note that some coastal movements on Wednesday night were very heavy, particular in New Jersey and DelMarVa. Another disturbance moving through the eastern Great Lakes on Thursday night spawned a new round of moderate to heavy flights, as the remainder of the region farther east saw little movement in primarily unfavorable southerly flow. Note that some localized flights occurred in the mid Atlantic, where conditions were locally favorable for the large number of migrants from previous nights’ to take flight.

American Wigeon, Ryan Schain
Gulf Coast and Southeast
Moderate to very heavy flights occurred across the region during the period. These movements occurred in several waves, but much of the region participate in the action and experienced excellent migration nights. The pulses of favorable conditions moved in two to three waves through the southeast, alternating with locally unfavorable conditions where migration was minimal. By the end of the period, movements were increasingly restricted to coastal areas from the Carolinas into Florida and west along the Gulf Coast through Texas.

Bufflehead, Ryan Schain
West
Light to moderate flights were scattered across the west last weekend. Additionally, a local flight in the Pacific Northwest on Tuesday night that reached moderate to locally heavy intensities was a bright spot in what was otherwise a mostly quiet remainder of the period across the region. Note that some areas of the southern Rockies saw more intense flights, in some places moderate to locally heavy, particularly last weekend and to end the period on Thursday night.
