              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Clouds got thick around 03:40, I decided to close the enclosure at 04:00 under completely cloudy skies.  We were seeing radar returns to our west but nothing too threatening, just prudent to close under cloudy skies.
By 04:40 we were now seeing radar returns just to our west moving this way.  We called it a night at this point.
