09 October 2013 Migration Report

As the low passes through, the ridge continues to build in behind pushing the winds out of the north and bringing a flood of migrants.  It was one of those signature nights the migrants wait for.  Streaming across the Strait, torrents of birds along the coast, and a deluge down the I5 corridor.  We are dripping with birds tonight!

Here is the local KRTX Reflectivity loop.
Here is the Regional loop
Here is the Seattle KATX loop.
Here’s Paul’s National Composite

This weather looks to hold for the next 48 to 72 hours.  It may get cold but the winds aloft will continue out of the north and the skies should  be clear — perfect fall conditions for the trip south.

Here is the 850mb winds loop.
Here is the Vorticity Forecast

A reminder about these links:  The regional level loops will break in a few days, NCAR does not archive the images past that.  Paul’s loop will remain in perpetuity — he’s like that.  The forecast links are dynamic and constantly updated.  That is; if you go to past posts and follow those links, they will look just like today’s link.

BONUS!!  Left click and open the links below for full animated .gifs of the THREE regional Reflectivity Loops.  Yes, THREE.  Whereas NCAR does not archive the Langley Hill radar College of DuPage does. Not only that, but that is where the .gif downloads are from.  Sweet, sweet, sweet!
