BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA WEDNESDAY, SEPTEMBER 23, 2020 ALL TIMES ARE IN EASTERN STANDARD TIME WARMER TODAY AS THE DROUGHT CONTINUES.... Today we observed a good visibility of 70 miles despite a smoke layer aloft. We were completely missed by some much needed rainfall too far to the east (refer to drought section below). Wind was about 15 mph on average from the northwest, becoming more westerly as the day went on. The highest gust so far today was 27 mph. Pressure continues to drop, but you wouldn't guess it looking at the sky. What's being seen is partial cloud cover, and a thin layer of smoke as well. The sun card has definitely been burning for the majority of the day. It has been 12 days since we've recorded any measurable rainfall (0.01" on the 11th). Only 0.51" has fallen for the month to date, which is 2.37 inches below normal. For the year, our deficit is running 4.58 inches below normal. The region continues to be generally in a moderate drought, however severe drought conditions are being observed across portions of south coastal Massachusetts and Rhode Island. -Drought section written by Matthew Douglas The high so far today is 77F, 8 degrees below the daily normal max of 69F.
