BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA WEDNESDAY, JUNE 26, 2024 ALL TIMES ARE IN EASTERN STANDARD TIME (EST) SUNRISE: 0409E SUNSET:  1925E HOT AND MUGGY WITH MIX OF SUN AND CLOUDS…. It has turned out to be another hot day today, and despite the rising dew point temperature, a steady breeze is making the heat more tolerable. Mid and high level clouds filled a good portion of the sky through the morning, with cumulus making an appearance by the early afternoon. Last night remained on the warmer side, as we only briefly cooled to 69F early this morning. Thereafter, temperatures rose quickly into the low 80s by 10am, and have continued to slowly climb into the mid 80s since. The southwest flow is advecting some moisture in our direction, as the dew point has reached the upper 60s. The wind has been steady today, with an average speed of 14mph out of the southwest and now the west-southwest. The peak gust to this point is 28mph, taking place at 2:31am this morning. The visibility has been fair, holding at 30 miles due to haziness. The maximum temperature so far today is 87F, which is 8 degrees above the normal high of 79F. The minimum temperature since midnight is 69F, which is 8 degrees above the normal low of 61F. ————————————————————– Today’s Observations: 7 A.M.
