ANOTHER CHILLY DAY, BUT WITH LESS WIND AND PLENTY OF SUNSHINE….

We have another nice day in progress with plenty of bright sunshine
with only a few high thin wispy clouds floating by, and a few low
to mid level clouds off in the distance.

It’s another chilly day with temperatures only reaching the low 40s
so far today, after early morning readings in the mid to upper 20s.
With much less wind today, it doesn’t feel all that bad out there in
the sun. The dew point has been gradually rising from the mid to
upper teens early this morning to the mid 20s by early this afternoon.

Although the wind has been lighter than in recent days, it’s still
been fairly steady out of the north-northeast to northeast. The
average speed for the day so far is around 11mph. The peak gust for
the day is 23mph, which occurred at 11:19am this morning.

Visibility has been holding at around 80 miles all day, so it’s been
another day with a spectacular view!

The maximum temperature for today since midnight is 43 degrees, this
is 8 degrees below the normal high of 51F. The minimum temperature
since midnight is 27F degrees, which is 7 degrees below the normal
low of 34F degrees.

OVERCAST SKIES AND COOLER TODAY FOLLOWING EARLY MORNING
THUNDERSTORMS….

An area of thunderstorms moved through the region early this
morning bringing Blue Hill its first thunderstorm day of the
year. Rainfall for the “event” totaled 0.58″, 0.30″ of which
fell within 1 hour between 4-5am. The activity moved out by
the 7am observation, and skies have been cloudy since, although
they have been thinning a bit in the last hour or so.

Temperatures are much cooler than yesterday with readings
only reaching the mid to upper 50s so far. This is due largely
to the lack of sunshine as well as the onshore flow.

The wind has generally been on the light side, but occasionally
does get a little gusty. The average speed has been around
8mph for the day so far, again mainly out of an easterly
direction, but it has become more southerly in the last hour
or so. The peak gust for the day so far is 23mph, which occurred
just after 12:30pm.

Visibility has been gradually improving as the day progresses,
from around 30 miles early this morning to around 50 miles by
early this afternoon.

The maximum temperature so far today is 58F degrees, which is
5 degrees below the normal high of 63F. The minimum temperature
since midnight is 47F degrees, which is 4 degrees above the
normal low of 43F.

Applications are now open for “Launch Your Career in Meteorology” 2024, a summer meteorology program for youth.

Join us at the Blue Hill Observatory on July 22 to July 26, 2024 for an exciting immersive week learning about meteorology and potential career paths from veteran meteorologist, Tim Kelley.

Our immersive summer meteorology workshop is for students who have an interest in the weather and wish to explore careers in meteorology and atmospheric science with professional meteorologists and scientists.

Participants in our week-long immersion workshop will:

  • Receive inspirational guidance from Tim Kelley, Veteran New England Meteorologist.
  • Experience an immersive understanding of meteorology through on-site discourse in the mornings followed by afternoon field trips.
  • Learn to accurately observe and forecast the weather.
  • Examine proven broadcasting techniques from local meteorologists.
  • Prepare and record a personal forecast in a TV studio.

Who can apply?

  • While we recommend the program to students ages 14 to 18 years old, other ages may also apply. Due to the immersive component of the program we can accept only eight participants each year.
  • Tuition for the workshop is $695. A financial aid program has been established by a generous donor. More details are shared within the application below.

Questions about the program may be directed to Don McCasland by email or phone: dmccasland@bluehill.org or 617-696-0562.
