BLUE HILL METEOROLOGICAL OBSERVATORY
MILTON, MASSACHUSETTS
ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA
SUNDAY, FEBRUARY 6, 2022
ALL TIMES ARE IN EASTERN STANDARD TIME
SUNRISE: 0653E
SUNSET: 1704E
MOSTLY SUNNY WITH LIGHT WINDS AND GOOD VISIBILITY ATOP
GREAT BLUE HILL….
We observed very chilly, yet clear conditions this morning,
with skies filling in with some low and upper level clouds
in the afternoon. Visibility was 75 miles on average, and
glaze ice on most surfaces has melted off due to bright
sunshine. Despite that, we still measured an inch of snow
depth on the summit at the 1 P.M. observation. Wind was
light and northwesterly with a max gust of barely 13 mph.
The high today was 25F, this is 10 degrees below the normal
high of 35F. The low since midnight is 15F, which is 13 degrees
below the normal minimum of 18F.
