Yesterday's front worked its way across the region. It was reinforced by a
secondary disturbance which brought rain and thunderstorms to the upper
Texas and Louisiana coasts this morning. Presently a squall line is
approaching New Orleans and a small flight of trans-Gulf migrants is
approaching the Mississippi delta from the SE. Otherwise the NEXRAD
coverage of the western Gulf coast in the TX/LA region is clear of
trans-Gulf migrants. This may be deceptive as migrants bucking heavy
weather over the Gulf almost always fly "down on the deck" which renders
them invisible to radar as they are literally flying "under the radar".
There is considerable radar evidence of diurnal migrating birds (probably
raptors, Anhingas, Am. White Pelicans, swallows, etc. especially southwest
of Corpus Christi. Birding should be good along the coast through
tomorrow.
