BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA DAILY DISCUSSION AND CLIMATE SUMMARY MONDAY, MARCH 17, 2014 ALL TIMES ARE IN EASTERN STANDARD TIME HIGH CLOUDINESS FROM LOW PRESSURE MOVING EAST TO OUR SOUTH COLDER ARCTIC AIR TODAY WITH A.M. LOW OF 13F TEMPERATURES ONLY IN MID 20’S EARLY AFTERNOON SNOW ON GROUND AT SUMMIT VERY PATCHY AND BEING RECORDED AS A TRACE FOR THE FIRST TIME TODAY A storm system which moved eastward into the Atlantic well to our south early today brought a late season significant snowfall event to the Middle Atlantic states.  While the high clouds had overspread our sky overnight only a few flakes of snow fell in a few places along the New England south coast. A reinforcing shot of Arctic air is following in the wake of the system headed out to sea to our south and temperatures are being held to the 20’s along with dew points in the single numbers below zero.  This comes after Sunday’s high reading of 34 degrees at mid afternoon. Although there are scattered patches of snow on the ground here at the summit, the snow cover on the ground has dropped to a trace today for the first time since February 3rd. Today’s Observations: 7 A.M.
