BLUE HILL METEOROLOGICAL OBSERVATORY
MILTON, MASSACHUSETTS
ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA
MONDAY, FEBRUARY 6, 2023
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0652E
SUNSET: 1705E
BACK TO THE THEME OF WINTER 2022-23, MAINLY CLOUDY AND MILD…
Clouds have been dominating the sky today with only some
filtered sunshine at times through mainly high and mid
level clouds. Despite the lack of sunshine, temperatures
have still warmed nicely into the mid to upper 40s.
The wind started the day out of the southwest, but has
gradually veered to the north and north-northeast as we
reach the afternoon hours. Wind speeds were light this
morning, but have since freshened with the wind shift.
Gusts of 20-25mph have been frequently occurring since
late morning. A rather large ocean storm passing well off
to our east is the culprit for the clouds and increasing
wind.
Visibility hasn’t been great today. 40 miles is the most
we’ve been able to see, but has slipped to around 35 miles
early this afternoon.
Today marks the 45 year anniversary of the Blizzard of ’78!
30.7 inches of snow was recorded here at Blue Hill over
the course of the 2 day storm. 13.0″ fell on the 6th, and
another 17.1″ fell on the 7th. Also a peak gust of 84mph
was measured out of the northeast on the 6th! Today is
quite a contrast to what happened during that event.
The high so far today is 46F degrees, which is 11 degrees
above the normal maximum of 35F. The low since midnight is
35F degrees, which is 17 degrees above the normal minimum
of 18F.
