More migration to our south as heavy precipitation precludes any influx into Upper Midwest
As the latest cold front marches eastward, migration continues in earnest across much of the country southeast of the frontal boundary. Trans-Gulf migrants came in high over the Texas and Louisiana coasts yesterday afternoon, and more birds poured into Florida from the Caribbean as well. Migration also continued throughout the desert Southwest and along the California up through the Pacific Northwest. Northerly winds and heavy precipitation on the backside of the front precluded any migration across the Great Plains and Upper Midwest.

More birds push north from Texas to New Jersey as the latest front marches east
The latest frontal boundary extends from Texas to New Jersey as of last night, bringing southerly flow from Mexico’s Yucatan Peninsula all the way through the Mid-Atlantic region. Trans-Gulf migration was evident late yesterday afternoon across the Texas and Louisiana Gulf Coast, and birds could also be seen making landfall in Florida this morning as they left Cuba after sunset last night. Heavy precipitation associated with the northeastern edge of the front may have caused some localized fallout conditions in the Washington D.C. area this morning as well. The Upper Midwest was again too far north of the frontal boundary to receive the bulk of the migrants heading towards the region, although the light and variable winds over the area did allow some birds already here to push farther to the northwest into the forecast zone.
