BLUE HILL METEOROLOGICAL OBSERVATORY MILTON, MASSACHUSETTS ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA SUNDAY, MARCH 10, 2024 ALL TIMES ARE IN EASTERN STANDARD TIME (EST) SUNRISE: 0604E SUNSET:  1745E HEAVY RAIN OVERNIGHT BRINGS OVER 1″ OF WATER, DRIER, BUT MILD CONDITIONS BEING OBSERVED TODAY… Just a note; Here at BHO we do not use DST, thus all times within our discussions will continue to be in EST. We do this for continuity purposes, as well as to keep our record keeping/reporting simplified. A quick moving, but potent system moved through the region overnight and early this morning bringing with it another bout of heavy rainfall and gusty winds. Rainfall totalled 1.28″, and marks the 3rd 1+ inch event within the first 10 days of the month. The monthly precipitation total is now up to 4.33″, a solid 2.76″ above what we’d normally expect by today’s date. The rain and drizzle tapered off by 9am this morning, and the clouds broke soon after. A mix of sun and clouds has been the theme since. Temperatures have been on the mild side today with readings in the mid-upper 40s. The wind became gusty overnight, and has remained that way through today so far. The average speed so far for the day has been around 18mph. Frequent gusts of 20-30mph have been occurring during the daylight hours, however gusts over 40mph were observed during the overnight hours into early this morning. The peak gust so far for today is 43mph, occurring at around 5am this morning. Visibility has improved markedly from this morning. We started the day in dense fog and visibility under 1/4 mile. The view has reached up to 80 miles by early this afternoon. The maximum temperature so far today is 49F degrees, which is 7 degrees above the normal high of 42F. The minimum temperature since midnight is 38F degrees, which is 13 degrees above the normal low of 25F. ————————————————————– Today’s Observations: 7 A.M.
