BLUE HILL METEOROLOGICAL OBSERVATORY
MILTON, MASSACHUSETTS
ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA

TUESDAY, NOVEMBER 10, 2020
ALL TIMES ARE IN EASTERN STANDARD TIME

WARM WEATHER CONTINUES, BUT MISSED THE RECORD FOR TODAY…

The big story of the last few days has certainly been
the warmth that has overspread the region. We got close
to tying the record for today, but fell just short with
a high of 74 degrees. As such the record of 75 degrees
set in 1931 still stands!

The 4 previous days records are as follows…

11/06/20: DAILY RECORD HIGH MAXIMUM TEMPERATURE OF 72F,
BREAKS PREVIOUS RECORD OF 71F SET IN 1959 AND 2015

11/07/20: DAILY RECORD HIGH MAXIMUM TEMPERATURE OF 75F,
TIES PREVIOUS RECORD OF 75F SET IN 1938

11/08/20: DAILY RECORD HIGH MAXIMUM TEMPERATURE OF 73F,
BREAKS PREVIOUS RECORD OF 72F SET IN 1938

11/09/20: DAILY RECORD HIGH MAXIMUM TEMPERATURE OF 74F,
BREAKS PREVIOUS RECORD OF 72F SET IN 1975

In addition to the warmth, an abundance of sunshine has
been observed today with mainly clear skies dominating,
the only clouds have been a few cirrus off in the distance.

Once again we’ve had alot of smoke and haze in the air
limiting the visibility. 15-20 miles was all we could
muster this morning, but has improved to around 50 miles
this afternoon.

The maximum temperature so far today is 74 degrees, this
is 22 degrees above the normal high of 52 degrees. The
minimum temperature since midnight has been 54 degrees,
this is 19 degrees above the normal low of 35 degrees.
