<x-flowed> BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS 02186 WEDNESDAY DECEMBER 11 2002 CORRECTED FOR DATE...YESTERDAY, TUESDAY, DECEMBER 10TH.. DISCUSSION FOR TODAY AT 1 P.M. FIRST 1/3 OF DECEMBER AVERAGES ALMOST 10 DEGREES BELOW WITH TOTAL DEPARTURE OF MINUS 94 DEGREES... This has been our coldest early December since 1989 with a mean temperature of 25 but consider this: in 1989 the average for the first ten days was 19 degrees. There was a 20 day stretch where the temperature never got above freezing. Amazingly there was only a trace of snow for the first half of that month and yet there was 0.15 inch of rain!
