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

MONDAY, MAY 16, 2022
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0422E
SUNSET:  1900E

THE FEEL OF SUMMER WITH WARM AND HUMID CONDITIONS….

Yesterday we set a new record high minimum with a low of 62F
being recorded. This beat the previous record of 58F set in
1896, 1961, and 2004.

As for today, the feel of summer has returned with
temperatures reaching the low to mid 80s. With dew points
in the lower 60s, there is a rather humid feel to the air.
The one saving grace here on the hill, we have a nice
southerly breeze blowing upwards to 20-25mph.

Adding to the summery look, the sky is filled with cumulus
congestus clouds, some of which have built up to become
towering cumulus and even cumulonimbus. Showers and
thunderstorms have developed across central parts of the
state with a rather vigorous thunderstorm currently passing
well to the WNW and NW of Blue Hill at the 1 P.M. observation.
It is not close enough however that any thunder has been
heard.

Visibility has been limited today. This morning due to thin
fog, and the balance of the day due to haziness and pollen.
Maximum value was only around 40 miles.

The high so far today is 83F, which is 16 degrees above the
normal maximum of 67F. The low since midnight is 58F, which
is 10 degrees above the normal minimum of 48F.
