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

WEDNESDAY, JANUARY 14, 2026
ALL TIMES ARE IN EASTERN STANDARD TIME (EST)
SUNRISE: 0711E
SUNSET:  1636E

DESPITE THE CLOUDY DAY, TEMPERATURES ARE WELL ABOVE NORMAL TODAY….

Today is the warmest day of the thaw, and likely to be the last
full day of it before winter returns later tomorrow. Skies have
been generally overcast all day. Cloud were thin enough during
the first half of the morning to allow for some filtered sun,
however they have since thickened leaving with a rather gray
day as we push through the early afternoon hours.

Despite the cloud cover, temperatures are running well above
normal today with readings reaching the upper 40s. This is around
15 degrees above the expected high for the date! Dew point values
are in the mid 30s, indicating a fairly decent increase in
atmospheric moisture compared to a couple of days ago.

The wind has been fairly steady out of the south-southwest today.
The average speed for the day so far is around 15mph. The peak
gust for the day so far is 36mph, which occurred just before
1:30am this morning.

Visibility has been mediocre today due to haziness. The view has
been limited to around 30-35 miles all day.

The maximum temperature so far today is 48F degrees, which is
14 grees above the normal high of 34F. The minimum temperature
since midnight is 39F degrees, which is 21 degrees above the
normal low of 18F.
