Yeah…sorta what I thought. I’ve seen this on social media quite a bit and how they try to “forecast” the migration (millions of birds per night) using what appears to be the ducting rings of clutter. It all seemed like voodoo to me. It’s like they’re using some kind of forecast prog algorithms to predict nightly inversions and say those areas have the highest migration rates.
The real bird sigs are more random. It seems like something was lost in translation between the met/radar experts and the bird scientists/programmers.
@radarman
I see this bird migration stuff from CornellLab a lot and I see UMass-Amherst as one of the contributors. Are they honestly using ground clutter from radiation inversions for this? That’s the impression I get from their daily tracking loops and examples. I thought maybe you would know more.

Way ahead of here. The grass has been up a few days and there’s some clover growing in the pawpaw patch. But that about it.
The forsythia is just starting to bloom.
Like Ditty said…they pulled it off. But with a 32C 5 min ob only you either need to wait for the 18/00z 6hr highs, the prelim climate report that comes out around 5p, or for BOX to announce it.
Next week is shit for all. Although I will add that we may get a couple of decent NW flow days late week once the core of the cold passes. Anything with sun is a plus.
