Area Forecast Discussion
National Weather Service Boston/Norton MA
105 AM EST Thu Dec 15 2022

.SYNOPSIS...

Quebec high pressure yields dry weather and easing winds tonight,
with moderating temperatures Thursday. Low pressure then tracks
along or near the southern New England coast Thu night and Fri,
delivering a chilly windswept rain, except heavy wet snow is
likely across the high terrain of western Massachusetts. Behind
this departing low, a drying and cooling trend this weekend,
along with blustery west to northwest winds. Dry weather likely
lingers into early next, but likely with colder than normal
conditions.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...

1 AM Update...

No changes in the latest update. Forecast remains on track.

10 PM Update...

Increased precipitation chances toward the latest NAMNest/NSSL
WRF guidance based on current observations of the shower
activity pushing in. Should see this activity diminishing by
roughly 05-07Z as it moves in. Rest of the forecast is on track.

Previous discussion...

Minor tweaks to the ongoing forecast this evening. Last couple
of runs of the HRRR and RAP were more potent with an offshore
band of showers set to move across the eastern MA coastal waters
into portions of eastern MA later this evening. Latest regional
radars also showed this band holding together pretty well,
despite likely overshooting the echoes to some degree. The
greatest risk for mostly rain showers should be across the
coastal waters, and towards the outer Cape and Nantucket.

Also brought temperatures and winds back in line with observed
trends. Gusty winds were diminishing a little bit faster.

Previous Discussion...

Gusty winds continue late this afternoon and evening as the
surface low offshore makes its closest pass between 4 and 7 pm.
This tightens the pressure gradient further and a 45kt+ jet
moves over the extreme eastern coast. Thus, for areas along
the coast like Cape Cod and the islands wind gusts will hold
steady or even slightly surge early this evening. Further
inland, after sundown surface temps drop and winds will cease to
mix down so should see a more rapid decrease of winds inland.
Tonight our blocking pattern begins to breakdown as the mid
level ridge approaches, as does high pressure at the surface
(leading to the end of gusty winds by sunup). On its way out,
though, a final shortwave rotates around the upper low and
brushes eastern southern New England. This, along with surface
winds veering to the northeast, will generate scattered ocean
effect rain showers over Cape Cod and potentially extending into
eastern Massachusetts as ocean effect snow showers; the window
for these rain and snow showers would generally be between 8pm
and midnight, give or take a few hours.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM FRIDAY/...

Thursday the trough-ridge-trough pattern continues its march
eastward, sliding the ridge axis across southern New England by
mid afternoon. This makes for a quiet and mostly dry day, with
light winds much of the day. The only exception to the dry
forecast may be for some scattered ocean effect rain showers
thanks to the northeasterly flow around the high. Best chance
for this precip will be over eastern MA and RI, with lesser
chance further west in MA and CT. So, even though the warm
frontal high clouds ahead of the approaching storm system will
only just be arriving by sunrise, surface northeast winds will
keep low level clouds around all day. Clouds thicken and lower
through the day and into the evening ahead of the approaching
system, while temperatures moderate a bit, especially for
eastern MA and coastal RI thanks to northeast flow off the
ocean, which is still in the 40s and low 50s. Highs here reach
into the low 40s.

While moisture (and cloudcover) increases on Thursday, the
appreciable precipitation (rain and snow, not counting the
previously mentioned ocean effect showers) should hold off until
Thursday evening as it will take some time to overcome mid level
dry air. The instigator of this is a low pressure that forms
over the mid Atlantic along the triple point of a parent low
over the Great Lakes. This low track up the northeast coast and
then over southern New England. Most guidance (with the
exception of the GFS) is honed in on a track over Cape Cod which
produces a cold rain scenario for much of the region, with heavy
heavy, wet snow over the higher terrain thanks to the moderate
antecedent temperatures. There is ample moisture to work with
given PWATs 1-2 standard deviations above normal, but again the
fly in the ointment will be marginal temperatures thanks to the
low level easterly flow. Warm advection aloft will initiate rain
and snow by 00Z Thursday, quickly overspreading the region. A
warm nose moves north rather quickly, so even some inland
locations that start off as snow should change to snow rather
quickly. For locations above 1,000 ft though, warmer air is
expected to be overcome by the strong easterly, upslope flow
which should induce some dynamic cooling. Easterly winds at 850
mb will be blowing at 40-45 kts. As we're just getting into some
of the high-resolution guidance, confidence in snow amounts by
sunrise Friday is rather low. Advisory level snows (3 to 7
inches in the Berkshires) are all but certain by 7 am (90%
probability in the EPS, 70% in the GEFS), with less certainty of
seeing warning criteria (7 inches or greater) by sunrise. The
struggle with this system will be a tight snowfall gradient
given the elevation dependent nature of it.

A Winter Storm Watch has been issued accordingly for the slopes
of the Berkshires as well as Hartford county, though only the
extreme northwest portion of Hartford county is expected to see
impacts from this system.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...

Highlights

* A windswept rain Friday, with heavy wet snow possible high
  terrain of western MA/CT

* Dry but trending colder & blustery this weekend into early next
  week

Precipitation...

Complex forecast for Friday into Saturday, with some lingering
uncertainty in the details. Temperatures in the lowest levels of
the atmosphere will marginally support snow, especially during
the daytime hours. Thus, accumulation snowfall across southern
New England will be very elevation-dependent. Expecting a sharp
gradient between where the snowfall accumulates significantly,
versus those that are mainly rain. A small change in temperature
could lead to a large change in snowfall. Will need to monitor
temperatures closely through this event.

At present, confined significant snowfall accumulations at
elevations at or above 1,000 ft. The consistency of the snowfall
for most should be heavy and wet, trending to a drier snowfall
at the highest elevations of southern New England. This may
change with later forecasts, so stay tuned.

Otherwise, expecting a significant precipitation event to begin
winding down from west to east during the day Friday, and
especially Friday night. Thinking there could be a brief final
burst of snow across the higher elevations when the colder air
surges south.

Strong East Winds...

Frontal wave is associated with a 65 kt low level easterly jet.
Model soundings suggest east winds may gusts up to 40-50 mph along
the coast. Wind Advisories may be needed for portions of the
coast, especially Cape Cod and the islands.

Coastal Flooding...astronomical tides are very low, and will
likely preclude any inundation or erosion issues.

Weekend and Early Next Week...

Frontal wave exits northeast Saturday, with a dry slot
overspreading our region. Thus, drying trend begins Saturday.
Mainly dry Sunday, but can't rule out a few flurries or snow
showers, as shortwave trough moves across the area. Behind this
trough, mainly dry with temperatures trending near or below
normal, along with blustery west winds.
