First image is of the winds aloft at 850 mb (approx 5000 ft). Winds over the state were mild and should have little effect on migration.  However, the conditions in Alaska and Canada look excellent for an exodus. Check your local migrant traps in the coming week things should be picking up a bit.

Second image is a snapshot of the base velocity showing north to south directionality at a peak of 20 to 25 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 8:18 pm pdst.

Density was up to 20dBZ and widespread.  Heaviest flight this season.  It’s officially fall!
