21 April 2017 – PNW Migration Update

Well, a relatively clear night with light winds out of the south and you would expect a surge of migrant activity.  But it was really rather muted.  We did get a smattering of 20+ dBZ returns; i just expected a much deeper and widespread response.

Arrivals, or increased reporting: Vaux’s Swifts and Wilson Warblers.

Two notes — another well organized low is headed our way (read, more rain) and there was a pretty interesting flight path down the Columbia and out to the coast that can be seen in last night’s loop; i don’t recall seeing that before.
