BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA TUESDAY, OCTOBER 15, 2024 ALL TIMES ARE IN EASTERN STANDARD TIME (EST) SUNRISE: 0558E SUNSET:  1701E MUCH IMPROVED WEATHER COMPARED TO OVER THE WEEKEND, STILL ON THE CHILLY SIDE HOWEVER…. Skies started the day clear with only a few clouds of various types and heights, however as the morning progressed, the mid and upper level clouds increased in coverage with low level clouds following suit by late morning. All in all there has been a mix of sun and clouds today, which is still much better than the damp and dreary conditions experienced for parts of the long holiday weekend. Temperatures started the day down in the mid 30s, which is nearly 10 degrees below the normal low for today’s date. Readings have recovered nicely into the low to mid 50s early this afternoon, but this is still also below normal for the date. Dew point readings have been generally in the mid to upper 30s all day, adding a chill to the air. The wind has been busy today, compared to the light values through most of yesterday. A west-northwesterly breeze today has been averaging around 12mph for the day so far. Frequent gusts exceeding 20mph have been occurring throughout the day, with a peak gust thus far of 27mph occurring during the 1pm observation period. Visibility has excellent all day, holding at around 80 miles. The maximum temperature so far today is 54F, which is 7 degrees below the normal high of 61F. The minimum temperature since midnight is 35F, which is 9 degrees below the normal low of 44F. ————————————————————– Today’s Observations: 7 A.M.
