First image is of the winds aloft at 850 mb (approx 5000 ft). Winds over the state were mixed. We had strong, up to 40 knot, winds off shore from the north which should bring some more migrants into the coastal areas. Inland the winds were light except in the gorge where we had westerlies up to 20 knots. It looks like these westerly winds extended the whole length of the Columbia last night. That may be a barrier to migrants to the north but may pull some interesting birds inland from the coast. Up north the winds were heavily favoring exodus, so maybe the next couple of days will bring in some migrant waves.
Second image is a snapshot of the base velocity showing north to south directionality at a peak of 15 to 20 knots.
Third image is an animated gif with snapshots every half hour of the base reflectivity above radar station RTX. Animation runs from around 8:00 pm pdst yesterday evening through 5:00 am pdst this morning. (Click on the thumbnails to view the full-sized images and animation.)
Sunset last night was at 7:52 pm pdst.
Density is still very light but the exodus bloom an hour or so after sunset was apparent. However, looking at the regional radar (image below), densities in the Puget Sound area continue to be much higher.
