BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA FRIDAY, AUGUST 14, 2020 ALL TIMES ARE IN EASTERN STANDARD TIME MOSTLY CLOUDY AND COOLER THAN DAYS PAST ATOP GREAT BLUE HILL…. Today was mostly cloudy, but with the majority of cloud cover being thin and high cirrostratus. A nice sea breeze was blowing in from the northeast at around 15 mph, keeping weather conditions favorable at the observatory. Visibility was limited by haze, only reaching 35 miles. The air has dried out as the day went on, with a humidity of 46% and a dew point of 58 at the 1 P.M. observation. This is notably dryer than earlier this week, when dew points were in the 70’s. The summit of Blue Hill is reaching a drought, with the monthly rain total being 1.61 inches below normal. Supporting evidence is the annual rain deficit of -3.53 inches. The high so far today is 82F, 2 degrees above the daily normal maximum of 80F. The low since midnight is 68F, 6 degrees above the normal minimum of 62F.
