BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA DAILY DISCUSSION AND CLIMATE SUMMARY TUESDAY, DECEMBER 1, 2015 ALL TIMES ARE IN EASTERN STANDARD TIME NOVEMBER COMES TO AN END, SIGNIFICANTLY DRIER THAN NORMAL AND SEVENTH WARMEST ON RECORD The month came to a close overnight with temperatures dipping to a low of 30F. Clouds have filtered in from the south this morning ahead of showers forecasted for this afternoon. By the 1:00 PM EST observation a brief rain shower had brought a trace of new rain, with rain showers visible to the W. Skies had darkened with a thick overcast of altostratus overspreading the region. November precipitation was well below normal, with a 2.18 inch deficit. Another dry month has added to the annual deficit with now stands at 9.12 inches below normal. A trace of snow that fell on the last day of the month was not enough to reverse the small snow deficit for the month of 2.3 inches below normal and 2.6 inches below normal for the season. November 2015 also made the top ten warmest Novembers on record here at BHO, with a 24-hour corrected average monthly temperature of 46.1F, making it the 7th warmest November since records began in 1885. BHO Warmest Novembers, deg F (1885-2015): 1) 47.9 in 2011 2) 47.4 in 1975 3) 47.1 in 2006 4) 46.4 in 1948 46.4 in 1979 46.4 in 2009 7) 46.1 in 2015 8) 46.0 in 2001 9) 45.7 in 1953 45.7 in 1999 PRELIMINARY STATS FOR OCTOBER 2015 TEMPERATURE, Deg.
