              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I closed at 21:45 due to a line of storms with precipitation showing up on the radar to our west.  I could see lightning and rain falling in the basin when I closed.
Rain started around 22:20 and we never re-opened for the remainder of the night.
I closed things down at 05:00
