BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA FRIDAY, NOVEMBER 1, 2024 ALL TIMES ARE IN EASTERN STANDARD TIME (EST) SUNRISE: 0618E SUNSET:  1637E MORNING CLOUDS FOLLOWED BY AFTERNOON SUN, BREEZY CONDITIONS…. This morning started with mostly cloudy skies and some thin fog in the area. As the cold front moved past us, scattered showers were observed in the area, but no precipitation for Blue Hill. The afternoon has brought partly cloudy skies with very breezy conditions. Temperatures are again warmer than normal. Our overnight low is currently 22 degrees above normal which will be a record minimum temperature if it holds. We also have beat our record high of 75F as well, so it’s been a warm start to the month. Winds have been very busy today, with a strong breeze out of the west-southwest averaging at around 15mph. The peak gust so far for the day is 34mph, which occurred just before noon. Visibility has been impacted by the rising dew points and general hazy conditions in the area. The afternoon clearing dropped the dew points enough to give us a 60 mile visibility by the 1pm observation. Unfortunately, we had a smoke plume develop ENE of the observatory in the early afternoon hours. The maximum temperature so far today is 76F, which is 21 degrees above the normal high of 55F. The minimum temperature since midnight is 60F, which is 22 degrees above the normal low of 38F. ————————————————————– PRELIMINARY STATS FOR OCTOBER 2024 TEMPERATURE, Deg. F Avg. Max. 64.7 [+3.7] Avg.
