BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA WEDNESDAY, APRIL 10, 2024 ALL TIMES ARE IN EASTERN STANDARD TIME (EST) SUNRISE: 0511E SUNSET:  1821E IT TURNED OUT TO BE A NICE DAY WITH SUNSHINE AND MILD TEMPERATURES…. Today has turned out to be better than expected with plenty of filtered sunshine up until about noon-time. Clouds are now increasing and thickening as more mid and high level clouds are being introduced to our skies making for overcast conditions by the 1pm observation. The temperature has reached the low to mid 60s once again early this afternoon, so it has been quite a pleasant day. The dew point has been holding in the mid 30s, so the air is still on the dry side. The wind has been fairly steady today, mainly out of a southerly direction. It’s been averaging at around 12mph so far for the day. It does get gusty at times with values reaching between 25-30mph. Visibility has been limited today due to haziness, with the view generally between 35-40 miles. The maximum temperature so far today is 65F degrees, which is 11 degrees above the normal high of 54F. The minimum temperature since midnight is 38F degrees, which is 2 degrees above the normal low of 36F. ————————————————————– Today’s Observations: 7 A.M.
