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

TUESDAY, NOVEMBER 29, 2022
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0652E
SUNSET:  1613E

MORE CLOUDS THAN SUN TODAY, COLDER BUT LESS WIND….

A lot of low level clouds, which appear to have been trapped
under an inversion, has been the theme today. As a result
of the lack of sunshine, the temperature has been quite slow
to rise today following a cold start. It has taken until
early this afternoon to finally reach 40F degrees.

Luckily, the wind has been on the lighter side today, thus
helping to keep the wind chill from being too uncomfortable.
The average wind speed for the day is around 9mph.

Visibility has been excellent all day despite the cloud cover.
The view has been 70-80 miles all day.

The high so far today is 40F, which is 5 degrees below the
normal maximum of 45F. The low since midnight is 28F, which is
2 degrees below the normal low of 30F.
