BLUE HILL METEOROLOGICAL OBSERVATORY
MILTON, MASSACHUSETTS
ELEVATION 635 FEET, 10 MILES SSW OF BOSTON, MA
MONDAY, JULY 25, 2022
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0430E
SUNSET: 1911E
HEAT WAVE ENDED AT 6 DAYS WITH RECORD HEAT YESTERDAY…
We couldn’t quite make it to 90F today and as such the heat
wave has ended here at Blue Hill. Either way a 6 day heat
wave is quite respectable for this part of the country.
Even though we didn’t make it to 90F today (high was 88F),
the dew point has been holding steady in the mid 70s all
day, so it’s been oppressively humid today. As a result,
it’s been quite uncomfortable for any outdoor activity.
Some light rain showers did move through between noon and 2pm,
but only produced a trace. We’re hoping some storms will move
through later this afternoon/evening to bring some more
substantial rainfall to the area.
The yearly rain deficit has now reached 8.77″ below normal!
Most of the area from the Greater Boston Areas and points north
northwest are under a severe drought. Remainder of the state
continues under moderate drought except for western Berkshire
county where it’s abnormally dry.
The high so far today is 88F, which is 6 degrees above the
normal maximum of 82F. The low since midnight is 75F, which
is 11 degrees above the normal minimum of 64F.
Looking back at yesterday, the high reached 99F degrees which
set a new record for the date, beating the previous record of
96F set back in 1987. We also tied the record high minimum
temperature of 73F, also set in 1952.
The 99F degrees is the highest temperature recorded here at
Blue Hill since July 22nd, 2011 when it also reached 99F. Here
is a list of highest maximum temperatures since the year 2000.
