BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA THURSDAY, NOVEMBER 11, 2021 ALL TIMES ARE IN EASTERN STANDARD TIME SUNRISE: 0630E SUNSET:  1628E SEASONABLE WITH LIGHT WIND AND GREAT VISIBILITY.... We observed a thin overcast for most of the day, mostly consisting of almost transparent cirrostratus clouds. Visibility was great at 80 miles, and sunshine was abundant all day.   Wind was very light and calm at the 10 A.M. observation. The max gust so far today happened very early this morning. Dew points hung around in the mid 20's, making for a very enjoyable Veteran's Day.   November has been a dry month thus far with the first 11 days not even registering a trace of rain. After the past 4 consecutive months have had above normal rainfall, this continues to be a rather nice reprieve. The current monthly rain deficit is 1.46 inches. That's fine considering the annual total is 9.50 inches above normal.   The high so far today is 55F, 3 degrees above the normal max of 52F. The low since midnight is 40F, 5 degrees above the normal low of 35F. -------------------------------------------------------------- PRELIMINARY STATS FOR OCTOBER 2021 TEMPERATURE, Deg. F Avg.
