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

WEDNESDAY, JULY 6, 2022
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0414E
SUNSET:  1924E

PARTLY CLOUDY WITH A COOL NORTHWESTERLY WIND
IN THE AFTERNOON….

We measured 0.12 inches total from rainfall yesterday, barely
chipping away at the rain deficit. The annual departure has
broke 7 inches! Drought monitor updated tomorrow.

Skies were partly cloudy with wind shifting from southwest
to northwest by noon. It’s breezy today with an average wind speed
around 15 mph and a max gust of 28 mph.

The dew point hit 70F this morning, making for a very oppressive
heat as temperatures climbed quickly into the low 80’s. However,
it dropped off considerably as the day went on. By the 1 P.M.
observation, the dew point was 60F with a cool breeze!

As the dew point fell off, visibility made a significant
increase from 35 miles to 80 miles by noon!

The high so far today is 82F, which is a degree above the
normal maximum of 81F. The low since midnight is 64F, which
is a degree above the normal minimum of 63F.
