Area Forecast Discussion
National Weather Service Boston/Norton MA
246 PM EDT Fri Jun 17 2022
.SYNOPSIS...
Much cooler this weekend with well below normal temperatures,
along with a few showers at times Saturday night into Sunday.
Drier conditions with near normal temperatures should return for
early next week.
&&
.NEAR TERM /THROUGH TONIGHT/...
The greatest forecast challenge through the late afternoon and
evening hours remains the coverage and severity of thunderstorms
that are currently draped across southern New England ahead of a
potent cold front. The cold front, which is currently draped across
northwestern MA, will continue to slide southeast. For much of
the morning and early afternoon, the greatest instability was
actually behind the line of storms, which, in addition to mid
level dry air, inhibited severe potential. A few storms pulsed
up over the last few hours, generating small hail and wind gusts
up to 40 kt, but began to die back when their updrafts were met
with the aforementioned limitations. While it took awhile for
the stratus deck to erode across southeast MA and RI, models
suggest that an area of greater instability is beginning to
build ahead of the current line of storms. It is expected that
our strongest storms of the day will occur as the convective
line moves into this region of MU CAPE values greater between
1000 and 1500J/kg. In general, the convective threat will
persist through 22 or 23Z this evening.
The convective window this afternoon continues to be very brief, as
thunderstorms are not expected to impact any general area for more
than an hour or two. The progressive cold front will quickly bring
an end to convection. We have already seen this occur across
portions of NW MA, where dewpoints have fallen upwards of 12
degrees in an hour at some observation stations.
A wind shift from the W/SW to the NW will be observed as the cold
front swings through, which has, again, already been observed across
northwest MA. Gusty NW winds will usher in MUCH colder and drier air
for the weekend. As dry air rushes in behind the front, rapid
clearing is anticipated. Overnight lows are expected to drop to
between 55 and 65 degrees; coolest across areas where the front has
already cleared, and warmest across the Cape and Islands.
&&
.SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/...
A steep trough digs into the region overnight; as an
unseasonably cold airmass settles over southern New England;
much cooler air is on tap for the weekend . Both 850 and 925mb
temperatures are dismally cold, with 850mb temps anticipated to
range between -1 and 3C... brr! Temperatures will be coldest
across the highest terrain, where some localities will struggle
to reach 60F on Saturday. Eastern MA and coastal RI will be
among the warmest spots tomorrow, as temperatures aloft are not
quite as cold; high temps will reach closer to 70F across the
coastal plain.
The day will begin with sunshine, but clouds will increase as the
day goes on as an increase as low and mid level moisture pivots into
our region thanks the cyclonic flow around a low centered to our
north and east.
Winds will also be gusty again tomorrow, as a somewhat generous low
level jet parks itself over southern New England for the weekend.
925mb winds range from 25 to 30 kt across the higher terrain, while
SE MA, the Cape, and Islands find some relief from the breeze in a
LLJ "donut hole"; gusts in these locations will be generally below
20 kt Saturday. It is not often that Nantucket experiences the least
gusty conditions of the entire CWA!
Surface dewpoints continue to plummet through the period, and will
settle into the low and mid 40s by early Sunday morning. Thankfully,
clouds and blustery NW flow will keep us from radiating overnight.
Lows will tumble back into the upper 40s to mid 50s Saturday
night, coolest across NW MA and warmest along the coast.
Shower chances increase overnight Saturday into Sunday as well,
primarily across eastern MA. Areas to the west of Worcester
look to remain dry.

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Highlights...
Highlights...
* Chilly nights this weekend. An unseasonably cool Sunday but temps
start to moderate for CT valley.
* Tranquil weather with moderating temps to start the new work week.
Details...
Still expecting a changeable weather pattern during this portion of
the forecast. We start out with the core of an anomalous cold pool
aloft just moving offshore of the southern New England coast Sunday
morning. The mid level flow over the North Atlantic looks rather
blocky and meridional for most of this time, so am not expecting
this cold pool to move quickly off to the east. That said, this
feature should at least be able to move far enough away from our
region where its influence on our weather will be greatly diminished.
At the surface, thinking an approaching warm front essentially
stalls mid week to our west, then occludes as its paired cold front
catches it and squeezes the warm sector of a low pressure in Canada
farther south.
Temperature-wise, most of southern New England is expected to be 5-
10 degrees below normal Sunday, transitioning to near normal Monday
and Tuesday. Not seeing signs of the truly oppressive heat gripping
much of the central part of the USA reaching here this week. Am
thinking temperatures will trend slightly above normal Wednesday
into Friday next week.
Thinking most of next week will remain dry across southern New
England, with only an approaching front the most likely focus for
any showers. Not entirely convinced this front will even reach our
region until late next week. Humidity should be slowly increasing as
next week progresses. As it does, cannot completely dismiss the
possibility of popup afternoon showers, especially across interior
southern New England, Tuesday into Thursday. Stuck with the
NationalBlend precipitation chances during this time, as it is a
larger ensemble. The greatest risk of any showers will be along and
west of I-91 in CT and MA.

.MARINE...
Forecaster Confidence Levels:
Low - less than 30 percent.
Medium - 30 to 60 percent.
High - greater than 60 percent.
Winds shift to W tonight with gusts to 20 kt then a period of
NW gusts 20-25 kt expected Sat. Poor vsbys expected this
afternoon/evening over south coastal waters in areas of dense
fog, improving later tonight. While winds look to die back
inside of a "donut hole" of the LLJ across our southeastern
waters on Saturday, heightened waves look to persist through
much of the weekend, so small crafts will likely need to be
extended to account for such through most of Saturday and
Sunday.
Outlook /Sunday through Wednesday/...
Juneteenth: Winds less than 25 kt. Seas up to 5 ft. Chance of
rain showers.
Sunday Night through Monday: Winds less than 25 kt. Areas of
seas approaching 5 ft.
