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

THURSDAY, MARCH 26, 2026
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0537E
SUNSET:  1803E

EARLY MORNING RAIN MOVES OUT, PARTIAL SUNSHINE AND MILDER WEATHER
TAKE OVER….

A touch of light rain moved through early this morning associated
with a warm front. Once this moved out, partial sunshine developed
late this morning, but has become more filtered early this
afternoon as high clouds stream across the area. It has also
turned quite mild with temperatures getting well above normal today.
Finally, spring has returned (for now)!

Temperatures have reached the low 60s by early this afternoon
which is a solid 15 degrees above normal for the date! Dew point
values have been in the low to mid 40s today, so it’s more “humid”
than it has been in recent days.

Winds have been pretty steady throughout the day, mainly out of the
southwest. The average speed for the day so far is around 16mph.
Gusts have been occasionally getting up around 30mph, with a peak
gust so far of 33mph occurring at 8:45am this morning.

The visibility is more limited today than yesterday. It was reduced
early this morning by rain and fog, down as low as 10 miles. It has
recovered some by early this afternoon, but it’s still somewhat
limited due to the increased level of moisture in the atmosphere.
The view at the 1pm observation is around 40 miles.

The maximum temperature so far today is 62F degrees, which is
15 degrees above the normal high of 47F. The minimum temperature
since midnight is 38F degrees, which is 8 degrees above the normal
low of 30F.
