Hi everyone, I've had a few people ask me for the sites where I check the nexrad images for indications of migration. The best site is: http://weather.radar.gov
I do have another spot bookmarked with the really long URL below: www.rap.ucar.edu/weather/radar/displayRad.php?icao=KUSA&prod=n0r&b kgr=black&endDate=20050421&endTime=-1&duration=0 What I like about this one is that it is a composite map that let's you look at the entire country at one time. I don't know of any radar sites for Mexico but I'm sure they're out there somewhere. One person did mention that the gulf coast of Alabama has seen a couple of fall out mornings so there is at least some movement in the eastern gulf area. I don't know if there have been any big lift offs from the Yucatan Peninsula headed to Texas. A good site for a basic introduction to Radar Ornithology is the Journey North website: http://www.learner.org/jnorth/weather/radar/index.html Again tonight it looks like northward movement in the central U.S. but further east than last night. This may be due to a cold front moving south through the Dakotas and Minnesota. I hope this helps folks find good images for their area.
