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

FRIDAY, APRIL 22, 2022
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0452E
SUNSET:  1834E

HAPPY EARTH DAY – ANOTHER SUNNY, ABOVE AVERAGE DAY…AND
YES, WINDY TOO!

While yesterday was gusty out of the south, today is once
again windy – this time out of the NW averaging 15 MPH.
Gusts over 30 MPH have been frequent. Thankfully temperatures
have found their way into the mid-60s under mostly sunny skies
making the wind a bit more tolerable. With the abundant sunshine,
stiff winds, and very dry air, there is an elevated fire danger
today.

Visibility is excellent with an average of about 80 miles.

The high so far today is 65F, which is 6 degrees above the
normal maximum of 59F. The low since midnight is 46F, which
is 5 degrees above the normal minimum of 41F.
