BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA SATURDAY, NOVEMBER 9, 2024 ALL TIMES ARE IN EASTERN STANDARD TIME (EST) SUNRISE: 0628E SUNSET:  1627E REMAINING BREEZY WITH ABUNDANT SUNSHINE…. Skies have largely been clear today, with just a few stratocumulus well off in the distance, particularly offshore. Following the passage of a weak cold front yesterday, the dew point has dropped into the mid 20s. Combined with the breeze, today’s conditions are not ideal for fighting the many wildfires in the area. Smoke plumes could be seen to the N-NNE and E this morning, with some others to our S-SSW becoming apparent by noon. After a warm spell the past several days, temperatures have returned to a more seasonable level. The low this morning was in the upper 30s, with temperatures slowly rising to the low 50s by the early afternoon. As before mentioned, the dew point has dropped off significantly compared to yesterday as an even drier air mass moves in. Winds were very active yesterday, and though they have slowed a bit, it has remained breezy. The average speed to this point is 16mph, mostly out of the north-northwest. Our peak gust occurred early this morning around 1:20am, with a speed of 40mph. Visibility has been excellent thanks to the low dew points, and has held steady at 80 miles. The maximum temperature so far today is 50F, which is 2 degrees below the normal high of 52F. The minimum temperature since midnight is 38F, which is 2 degrees above the normal low of 36F. November began quite warm, with two monthly top five temperatures and the latest 80 ever observed. This information was compiled by our chief scientist, Mike Iacono: BHO Warmest November Temperatures, deg F (1885-2024): 1) 81 on 2 Nov 1950 2) 80 on 6 Nov 2024 3) 78 on 2 Nov 1982 4) 77 on 4 Nov 1987 77 on 1 Nov 2024 6) 76 on 5 Nov 1994 ————————————————————– Today’s Observations: 7 A.M.
