              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started with increasing clouds and storms approaching us. By 20:00 we were entirely clouded out, with radar returns all around us. We ended up in a cloud. It did not start raining on site until 00:00.  High humidity and scattered rain plagued us the rest of the night. Thundserstorms started at 04:00. We never opened.
