21 February 2017 – (PNW) Migration Update

… (PNW) in parentheses because we can’t see squat on the radar through the heavy cloud cover.

But, birds are moving north and HERE is a great example from the Anzo Borrego.

Update: it occurred to me that you might need to subscribe to the San Diego Region Birding list; not something everybody might want to do.  So HERE is a direct link to the video.

14 February 2017 – Ready or Not, Here They Come

Sheesh!  I think this is the earliest 20 dBZ pulse i have seen.  Right up the middle of the Valley.  Probably water fowl coming off the NWR’s headed north.

04 November 2016 – PNW Migration Update

Light north winds but clear skies, even with migration winding down, we still have a few migrants moving south.

With RTX off line we’ll take a look at the other two regional radars today; ATX in Seattle and LGX on the coast at Gray’s Harbor.

20 October 2016 – PNW Migration Update

It might be the winds out of the south or it might be that we’re getting a little long in the tooth, but the migration last night was pretty weak.  Best action was up against the spine of the Cascades.

26 October 2016 – PNW Migration Update

Strong winds out of the south and widespread rain developing over night; pretty crappy conditions for migrants.  But at low levels, especially early in the evening, some birds were on the move.  Taking a look at both the Base Reflectivity and the Hydrometeor Classification loops we can see, even in adverse conditions, some birds continue to pound south.  Probably the strong flying waterfowl.

25 October 2016 – PNW Migration Update

As expected from what we saw yesterday the south winds continued through the night with scattered rain cells.  And, very low levels of migrants passing through.

So lets take a look at the National Composite because there has to be some action going on somewhere.  Looking at the wind map we can see the Central Flyway pretty much shut down and the best conditions are in the Mississippi and southern Atlantic Flyways.

And the radar shows:
