11 Apr 2014 PNW Migration Update

Winds are out of the north as the high pressure ridge remains in place offshore.  But they are not proving to be overly restrictive.  Birds are on the move again.  Not quite as heavy as last night – probably due to the increased wind speed.

Barn Swallows are now in the area.  Black-thoated Grays, Empids, and Kingbirds are just to our south.  Ah, don’t you just love this time of the year!

Here is Paul’s archived National Radar Composite from yesterday.  Now, if you compare the “grand view” with the radar composite it just makes sense.

And here are the weather maps (click on any image to bring up a full gallery view)

Let me take just a bit here to talk about http://earth.nullschool.net,  This code is just amazing.  You can zoom in, zoom out, and rotate to anywhere on earth.  You can select the winds at eight different altitudes.  There are eight weather data overlays available.  There are eight earth projections available.  You can go back in time by 3 hr or daily intervals up to 5 days!  I am just simply blown away.   Cameron Beccario (@cambecc) is a freaking genius!  Here’s an update:  you can even switch the mode to observer ocean currents!
