First image is of the winds aloft at 850 mb (approx 5000 ft). Winds over the state, and the whole Pacific Flyway, were light and variable at 5 to 10 knots.

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 7:30 pm pdst.

Density was decent but reflectivity readings did not get up into the 20 dBz range last night.  New birds should be in the area today, but spread out.
