BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA TUESDAY, MARCH 12, 2024 ALL TIMES ARE IN EASTERN STANDARD TIME (EST) SUNRISE: 0600E SUNSET:  1748E SUNNY AND WARM WITH BRISK BREEZE… Aside from some distant clouds, the skies have been largely clear today, making it a great day to enjoy some sunshine! Temperatures are above average for the time of year, beginning in the low 30s and quickly rising to the low 50s by the afternoon. The stiff breeze has been making it feel a bit cooler, however. This airmass is quite dry, as the dew point has remained in the upper teens to low 20s all day. Though not as active as yesterday, the winds remain noticeable. Our average so far is around 15mph, mostly out of the west-northwest. The peak gust to this point is around 37mph, taking place just before 1pm. Visibility has remained great today, with views holding at 80 miles! The maximum temperature so far today is 52F degrees, which is 9 degrees above the normal high of 43F. The minimum temperature since midnight is 33F degrees, which is 7 degrees above the normal low of 26F. ————————————————————– Today’s Observations: 7 A.M.
