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

SATURDAY, MAY 28, 2022
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0412E
SUNSET:  1911E

WARM AND MUGGY WITH LIMITED VISIBILITY AND
RAINFALL TO THE WEST….

Today is showing some slightly unfavorable weather with
limited visibility and dew points in the mid 60’s. Skies
are mostly overcast with some breaks of sun throughout the
day. This is following some thunderstorms this morning that
left us with 0.23 inches of rainfall. There is more on its
way according to radar imagery, but the distant rainfall is
very hard to see; due to a 20 mile visibility from haze.

We experienced some very light rain showers between 8 and 9 this
morning, barely leaving a trace in the gauge.

The high so far today is 70F, which is the same as the
normal maximum of 70F. The low since midnight is 64F, which
is 12 degrees above the normal minimum of 52F.
