              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
The skies didn't look promising before sunset but the clouds parted just as the sun set.  I opened, got focused, and my observer got on their target, and then the clouds rolled back in.  Since there was precip earlier in this system, and radar was showing precip just to our N, I was conservative and closed.
About an hour later the sky cleared again, but humidity was rising and close to limits.  I decided to wait and 20 mins later humidity went over the limits and the clouds came back.
We fought clouds and humidity for most of the night.  I finially re-opened around 03:40, but we still fought humidity and I just pushed the limits since the primary was warm.
