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

SATURDAY, JULY 9, 2022
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0416E
SUNSET:  1922E

ALMOST CLOUDLESS WITH GREAT VISIBILITY ….

Skies were clear today for the most part with some passing
cumulus and cirrus clouds. Visibility was great at 80 miles,
and a light sea breeze persisted as the day went on. Wind
was on the lighter side, barely reaching 20 mph this morning.

We continue our dry stretch with a deficit of a half inch
on the month and almost 7.5 inches on the year. Most of
the state is in a moderate drought save the Berkshires
and Cape Cod. These areas are still rated as “Abnormally
Dry”, according to the drought monitor.

The high so far today is 78F, which is 4 degrees below the
normal maximum of 82F. The low since midnight is 65F, which
is a degree above the normal minimum of 64F.
