First image is of the winds aloft at 850 mb (approx 5000 ft). The winds up in BC are favoring inland exodus tonight.  However as they hit the gorge they will probably put down as there are some 25 knot westerlies to contend with.

Second image is of the surface winds and pressure.  The high pressure system off the coast has weakened but there are still some northerly winds along the coast that could entice some migrants to take to the skies.

The RTX radar was down last again night.
