04 March 2016 – PNW Migration Update

A very interesting night.  We had some decent southerly winds aloft and only isolated cells of disturbance.

There was widespread low level migration across the region.  There were also two interesting heavy returns past the 20 dBZ level.  The first arising from the Sauvie Island/Ridgefield area.  OK, those are waterfowl.

But the second is that same odd return originating from Linn and Marion Counties east of I5 and heading straight for Mt. Hood.  We saw this earlier this season.  I pulled up the HC loop and we can see a DS (Dry Snow) return with the same time stamp and trajectory.  So i am really not sure what is going on here.

Anyway, nice to have some clear air and see our feathered friends heading north.  First Ospreys are being reported in the metro region.

Speaking of friends,  David Irons just started a blog which you can find HERE.  David is one of the best birders on the planet and i am looking forward to seeing what he does with this.  And David, if you come across this post — get an RSS link so i can get your posts to show up in my reader; much easier for me to follow along without having to check in every now and then.

Here is today’s gallery:
