                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
Opened in twilight and got as much data as we could before a heavy cloud bank with
radar returns moved over us. After that wave hit the ridge radar returns continued
over the mountains for several hours. Rained a little onsite near midnight. Fog
and/or high humidity the rest of the night.
