An evening like tonight is great for following the fall migration on radar. There is a slight northerly breeze with relatively clear skies. At approx. 8:36 PM there was very little to see on the Camano Island radar. At 9:24 it was a different story. By looking at the Doppler radar signature one could clearly see south bound objects on the radar. As the weather was clear, the objects, moving at 10 to 30 knots, must have been birds. I then looked at the Bismarck, ND radar where I could see a striking example of the south bound Doppler signature. I saved these images to disc as I can not attach them to a Tweeters post. I would be happy to forward them to anyone who is interested. In the mean time, here is a link to the NEXRAD radar page: http://weather.rap.ucar.edu/radar/ Click on your location of choice. A BASE REFLECTIVITY image, which will not show the Doppler signature and you will not see the migration. Click on the image and a VELOCITY image will come up showing the Doppler shift of the radar signal. Remember, a shift toward the blue indicates object moving toward the radar and a shift toward the red shows objects moving away from the radar. In this case the objects are moving to the south. Have another look next March, April and May for north bound birds.
