BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA MONDAY, AUGUST 24, 2020 ALL TIMES ARE IN EASTERN STANDARD TIME WARM AND HUMID WEATHER CONTINUES… After yesterday’s exciting weather conditions on Blue Hill, from the complete undercast in the morning to the severe thunderstorm that brought a strong wind gust, hail, and torrential rainfall in the late afternoon/early evening, today so far has been quite tranquil! To recap the events of yesterday, the severe storm brought a wind gust to 60 mph from the WNW at 4:46 P.M., estimated penny sized (0.50″ diameter) hail, and heavy rainfall totaling 2.21 inches. We also broke or tied a few records yesterday; First we set a new record high temperature for the day of 89 degrees. The previous record was 88 degrees set in 1918, 1947, 1949, and 1996. We broke the rainfall record for the date with 2.21″. The previous record was 2.09″ set back in 2010. Lastly we tied the peak wind gust record for the date with 60 mph, which also occurred back in 1940! Today so far has been very quiet with varying amounts of cloud cover mixed with sun. Humidity levels has been quite high with dew points hanging around in the upper 60s and low 70s, making it feel pretty uncomfortable outside. The wind has been very light most of the day, only averaging around 6 mph since 7 A.M. The peak gust so far has only been around 17 mph. The high so far today is 86F, 8 degrees above the daily normal maximum of 78F. The low since midnight is 67F, which is 6 degrees above the normal minimum of 61F. Today’s Observations: 7 A.M.
