15 September 2015 – PNW Migration Update

In spite of decent conditions, migration in the area remains tepid at best.

So, lets look elsewhere.  Today we’ll look at the national level and one curious spot. Nationally take a look at the Wind map, note the strong flows up the Central and Mississippi Flyways, and then note the paucity of migrants.  The east coast, with milder conditions, dominates the scene last night.  Since we showed Jacksonville recently i’m leaving that out, but it was jamming again last night with returns again pushing the 40 dBZ levels.

So, take a look at the loop from El Paso, TX from last night.  What i am curious about is the ring of returns that pops up for about an hour — just before avian migration takes place.  Look for it in the lower center of the frame over in Mexico.  I’m GUESSING, bats.  But, if anyone knows for sure – let me know.  Whatever they are, there are a ton of them dispersing from a single point.
