BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA WEDNESDAY, OCTOBER 9, 2024 ALL TIMES ARE IN EASTERN STANDARD TIME (EST) SUNRISE: 0551E SUNSET:  1711E ANOTHER VERY PLEASANT FALL DAY IN PROGRESS UNDER MAINLY SUNNY SKIES AND SEASONABLE TEMPERATURES…. Today is once again featuring plenty of sunshine with some building diurnal cumulus clouds popping up thanks to a cool pool of air aloft over the region. The air isn’t quite as clear as it was yesterday as the visibility lowered a bit from 80 miles early this morning to 70 miles by early this afternoon. Nonetheless, it’s still a great day for any outdoor activities. Temperatures started the day in the mid 40s again today, but warmed into the low to mid 60s by early this afternoon. The dew point has been fairly steady in the low 40s all day. Winds have been fairly steady today averaging around 9mph mainly out of the west-northwest. It has become a bit gusty early this afternoon, again thanks to the aforementioned mixing from aloft. The peak gust so far is 24mph, which occurred around noon-time. The maximum temperature so far today is 63F, which is 1 degree below the normal high of 64F. The minimum temperature since midnight is 46F, which is 1 degree below the normal low of 47F. ————————————————————– Today’s Observations: 7 A.M.
