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

FRIDAY, OCTOBER 28, 2022
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0613E
SUNSET:  1643E

FAIR WEATHER, AND A LITTLE CHILLY ON THE SUMMIT….

Today we observed 85 miles of visibility on average,
as dew points persisted in the mid 30’s. The weather
was comfortable with a cool northeasterly breeze around
10 mph on average. The max gust so far today is 20 mph.

Cloud cover was overcast today, mostly consisting of
upper level clouds.

The drought monitor shows great improvement as most
areas of Massachusetts are reaching normality with the
rainfall this month. There is still a moderate drought in the
Boston area and a severe drought in most of Essex county.

The monthly rain total is 5.69 inches, which shows a 0.92 inch
surplus on the month. On the year, our total is 33.68 inches.
This gives us a deficit of 9.76 inches so far this year.

The high so far today is 50F, which is 6 degrees below the
normal maximum of 56F. The low since midnight is 36F, which
is 3 degrees below the normal low of 39F.
