First image is the winds aloft at 850 mb (approx 5000 ft). 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 8:45 pm pdst.

20 to 25 knot northerly winds along the coast may bring some new shorebird activity.  10 to 15 knot winds over the valley may escort some early migrants to your neighborhood mud puddles.

Overall density is still rather light.
