BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS 02186 SUNDAY DECEMBER 29 2002 DISCUSSION TODAY AT 11 A.M. Cold and calm here at BHO yet overcast as high cirrus obstruct about 5/8 of our blue sky. Temperatures rebounding this morning here at the Observatory from 24F into the lower 30's at this hour. Winds are relatively light averaging only 14 MPH out of the west. Overnight we received a very small amount of snowfall that could be seen on the snow-boards as well as in the standard gauge; however, the precipitation was not enough to be measured thus a trace of snow. For the year at BHO, our precipitation is 2.74 inches above average and with only 2 more days left in 2002, precipitation will remain above average due to this very wet December where we have received 6.76 inches of liquid precipitation.
