              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out with storms all around us. There was one hell of a lightning show to the east!! We were able to open around 9pm as the storms were firmly staying to the east at that point. However, the humidity starting creeping up, then clouds, then danger clouds. We closed at midnight once we could no longer punch through the clouds. The rain started back up around 3am and, once it stopped, we had high humidity and clouds the rest of the night.
no problems tonight.
