BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA FRIDAY, AUGUST 7, 2020 ALL TIMES ARE IN EASTERN STANDARD TIME A FAIRLY QUIET DAY - MOSTLY CLOUDY SKIES AND A FEW SPRINKLES ATOP GREAT BLUE HILL... Not a whole lot to write home about today as we close out the first full workweek of August. Skies have been predominantly cloudy for the duration of the day occasionally ejecting a sprinkle here and there, but no measurable precipitation. The ceiling has been comprised primarily of mid-and high-altitude clouds so visibility has not been too poor- ranging anywhere from 40 miles to 65 miles. A bit of a break in the heat today as temperatures bottomed out in the upper-60s early this morning, and only mustering 79 degrees by 1PM. We will likely dial up the heat (and humidity) yet again by the time Sunday rolls in, so enjoy these more  manageable temperatures and dew points for another few days. Winds continue to be rather gentle with a peak gust of 14 MPH thus far.    The high so far today is 79F, which is 2 degrees below the daily normal high of 81F. The low since midnight is 68F, which is 5 degrees above the daily normal low of 63F. PRELIMINARY STATS FOR JULY 2020 TEMPERATURE, Deg. F Avg. Max. 83.5 [+2.7] Avg.
