First image is of the winds aloft at 850 mb (approx 5000 ft). Winds over the state were, like last night, light and mainly out of the north.
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 7:58 pm pdst.
Density was undetermined as the radar was in precipitation mode all night. Exodus bloom an hour or so after sunset was apparent though.
