Upper winds are S to SW at 25 to 30 kts - the kind of weather that really
propels migrants northward, although it usually does add up to birds on the
ground as migrants take advantage of the boost to penetrate well inland
before they land. South of Brownsville and south of Corpus Christi are some
large kettles of kettle-and-glide migrants, probably raptors (Broad-winged
Hawks and Turkey Vulture are numerically dominant at this stage of the
season). Some of these targets may represent waders and other coastal
species.
A good deal of the observed reflectivity is dust, pollen, insects and
other aerial detritus.
