BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA SATURDAY, JUNE 22, 2024 ALL TIMES ARE IN EASTERN STANDARD TIME (EST) SUNRISE: 0408E SUNSET:  1925E COOLER AND GLOOMY WITH ONSHORE FLOW…. Following thunderstorms yesterday evening, which left us with 0.90″ of rain, conditions have been rather gloomy so far today. We spent almost the entire morning in the clouds, which have only just begun to lift. Low clouds still fill the sky as of the 1pm observation. Temperatures bottomed out last night in the low 60s, and began to slowly rise, reaching the upper 60s. Then, around 9am, the wind picked up out of the northeast, causing the temperatures to fall back into the mid 60s, where they have remained since. The dew point has followed a similar trend. Winds were very light to calm through 9am, after which they picked up a bit. The average for the day is only 5mph. The peak gust to this point is a bit sad, only 16mph occurring a bit after noon time. Visibility has been rather poor through the day today, mainly due to fog and persistent low clouds. So far, this has ranged from 1/16 of a mile to as much as 10 miles by the afternoon. The maximum temperature so far today is 69F degrees, which is 9 degrees below the normal high of 78F. The minimum temperature since midnight is 62F, which is 2 degrees above the normal low of 60F. ————————————————————– Today’s Observations: 7 A.M.
