10/29/2011 7:00 AM 0.49 T M T M Precipitation was a mixture of rain and snow. There was only a light dusting of snow on grassy areas so I was unable to get an accurate snow measurement.
10/30/2011 7:00 AM 0.72 0.2 M 0.2 M Snow is confined to grassy areas and deck. Snow is too shallow and icy to get a core sample. The majority of precipitation was in the form of rain yesterday.
10/31/2011 7:00 AM 0.00 0.0 M 0.0 M Frost on the ground this morning but most of the snow melted yesterday except for some shady areas.
