              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Well, we didn't get much of any snow, the smallest of flurries for a few minutes, but we did get high winds (topping at 60 mph), lots of dust (you could smell it), freezing fog, and clouds, clouds, clouds. Things cleared up around 4:30 (the limit for the observer) but then the wind came back up at the humidity was still high.
No problems tonight
