BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA TUESDAY, JUNE 25, 2024 ALL TIMES ARE IN EASTERN STANDARD TIME (EST) SUNRISE: 0409E SUNSET:  1925E MOSTLY CLEAR SKIES WITH BRILLIANT SUNSHINE, WARMER…. We began the morning without a cloud in sight, but since then some cirrus have made an appearance to the west, along with fair weather cumulus popping up locally. Still, abundant sunshine has been the rule. We began the morning in the low 60s, rising quickly into mid 80s by the afternoon. The dew point has hovered right around 60F, so while it is certainly hot, it does not feel too sticky out there. The wind was more active in the early morning than it is now, with an average speed of 11mph so far. The flow is out of the northwest. The peak gust took place just after midnight, with a value of 26mph. Visibility has been hindered by haziness, with views dropping from 40 miles to 30 miles as the day has progressed. The maximum temperature so far today is 85F, which is 6 degrees above the normal high of 79F. The minimum temperature since midnight is 61F, which is equal to the normal low of 61F. ————————————————————– Today’s Observations: 7 A.M.
