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

THURSDAY, MARCH 9, 2023
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0607E
SUNSET:  1743E

A MIX OF SUN AND CLOUDS, BUT MORE SUNSHINE THAN PRIOR DAYS…

Clouds dominated this morning, but have broken significantly
early this afternoon to allow for a decent amount of sunshine.
Temperatures are responding nicely with readings reaching
the upper 40s. With much lighter winds than the last few days,
it actually feels quite nice out there today.

As mentioned, the wind is much lighter today with an average
speed for the day so far around 12mph, with a decreasing trend.
We had some gusts this morning over 20mph, but they have come
down as we move into the afternoon hours.

Visibility has been excellent with views of 70-80 miles all
day.

The high so far today is 47F, which is 5 degrees above the normal
maximum of 42F. The low since midnight is 32F, which is 7 degrees
above the normal low of 25F.
