01 May 2015 — PNW Migration Update

A high pressure ridge is building just off shore.  The leading edge is not quite here yet so the north winds associated with that are probably a day out.  While that bodes well for the weekend weather it will slow north bound birds down.

Last night under neutral conditions we had some heavy movement and that will bring the next pulse of migrants into the region.

No word on Western Wood Pewee or Willow Flycatchers yet for the Portland Metro area.
