First image is of the winds aloft at 850 mb (approx 5000 ft). Winds over the state were all out of the north. We had 20 knot winds along the coast which could bring some more migrants into these areas. Inland the winds were light but out of the north. The westerly winds up the Columbia have stopped for now. Up north the winds were heavily favoring exodus, so maybe the next couple of days will bring in some migrant waves. The strong westerly winds in the far north should stage some migrants for the central and Mississippi flyways.
Second image is a snapshot of the base velocity showing north to south directionality at a peak of 20 to 25knots, picking up 5 knots or so from the tail winds.
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 7:50 pm pdst.
Density is picking up and the exodus bloom an hour or so after sunset was apparent.
