              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
There wasn't much of any hope in opening tonight. We had gusts over 40 mph with high dust counts. When that died down we had high humidity, then freezing fog, then clouds and light snow. There was no accumulation but it was still lightly falling by 5:30, which was the cut off time for CU02.
Happily, arctic seems to have had no issues! So no problems tonight.
