TODAY’S STORM LEAVES US WITH RECORD-BREAKING SNOWFALL
ATOP GREAT BLUE HILL….
Today’s nor’easter provided us with 27.5 inches of snowfall and
1.83 inches of liquefied precipitation as of 7 P.M. The previous
snowfall record for this date is 8.0 inches in 1943, and is thus
replaced in major fashion. Another record broken is the highest
snowfall for the month of 25.2 inches, set on January 27th, 2015.
The storm yielded snowfall rates of almost 3 inches per hour,
and blizzard conditions were seen for at least 4 consecutive hours.
Average wind speeds exceeded 25 mph from the north for most of the
day, and frequent gusts over 40 mph were seen. The highest gust
seen so far today was 55 mph. The max gust record for the calendar
date is 72 mph from the northwest, set in 1973.
Visibility was negligible, with 4 miles being the highest visibility
at the 7 P.M. observation. The lowest visibility was very close to
zero, as near whiteout conditions were observed.
The high so far today is 28F, this is 6 degrees below the normal
high of 34F. The low since midnight is 10F, which is 7 degrees
below the normal minimum of 17F.
