To radar watchers out there, does anyone care to comment on the reflectivity radar loops tonight for the area 10-20 miles northwest of Philadelphia?
1. On the ground, I've heard and recorded a lot of longer "tseeps" (20-50 for some minutes) - which is more than I've ever heard around here. I'd have to guess most sound sparrowish (white-throated and plus some short ones) - so nothing surprising given the time of year. 2. There's not much wind but what there is out of a southerly direction (it feels like Florida right now here) so not what I would think would be favorable for a heavy migration. Although if you look at the surface streamlines, it looks like we are on the edge of a change in wind direction/speed: http://homes.comet.ucar.edu/~guarente/birdweather/stream.htm The upper level wind direction is definitely out of the southwest. 3. There's rain in the area and I see a lot of green on the radar* (not blue) - so I'm having a hard time.
