No trans-Gulf migration was visible on the radar last night, while nocturnal migration proceeded at break-neck pace across the eastern half of the U.S. As a new set of low pressure cells approached from the Plains region, associated southerly winds triggered heavy migration up through the central region, including Wisconsin. Light migration was also evident up through interior California and into the Pacific Northwest.

Since I was ‘out of the office’ on this morning, the only content here is the radar.

Trans-Gulf migrants arrived along the Louisiana and East Texas coasts yesterday afternoon, followed my heavy migration up through the Central and Southeastern U.S. High pressure over the Northeast suppressed any major nocturnal flight last night. Migrants continued to march north across the western U.S. although densities were considerably lower than in the east. Fallout potential exists for southern Minnesota and southwestern Wisconsin this morning as low pressure brought some heavy precipitation to the region early today.

Migration was widespread yesterday, beginning with trans-Gulf movement hitting the TX/LA coast yesterday afternoon and followed by nocturnal migration across the eastern half of the U.S. and the Pacific Coast through the early morning hours. Strong westerly winds pushed birds to the Mid Atlantic coast and heavy storm activity over Texas and Oklahoma increased fallout potential for those area.

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.
