BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA MONDAY, NOVEMBER 8, 2021 ALL TIMES ARE IN EASTERN STANDARD TIME SUNRISE: 0627E SUNSET: 1629E ....SOME MORNING CLOUDS GAVE WAY TO BRILLIANT SUNSHINE AND MILDER TEMPS.... Exceptional fall weather is occurring on this Monday with a boat load of sunshine and temperatures that are above normal for this time of year. I'm sure many decided to take lunch outdoors in an attempt to soak up the last vestiges of decent weather while it lasts. Visibility hasn't been great today however, with a bit of haziness in the air. We've been able to see only around 50 miles all day. Not really what you'd expected with such dry air in place, as dew points are still holding in the low-mid 30s. Not much of a breeze to speak of either today with wind speeds only averaging around 10mph. The peak gust so far today is 19mph, which occurred before sunrise this morning. The high so far today is 60F, 7 degrees above the normal max of 53F. The low since midnight is 38F, 2 degrees above the normal low of 36F. -------------------------------------------------------------- PRELIMINARY STATS FOR OCTOBER 2021 TEMPERATURE, Deg. F Avg.
