 Observing Specialist: J.Dembicky
 Happy Thanksgiving
 High humidity kept us closed at the start of the night.  Beautifully
 clear skies, considering they were predicting a snowstorm for today!
 Humidity stayed high but clouds started appearing after around 20:00 and
 we had clouds and clear sky all night with it finally clouding up
 completely around 4AM.  We gave up around 4:30 with light snow flurries.
