Area Forecast Discussion
National Weather Service Boston/Norton MA
353 AM EST Sun Dec 8 2019

.SYNOPSIS...
Strong high pressure over southern New England this morning will
shift off the coast during the afternoon, which will start a
return flow of increasingly milder and more moist air. Scattered
showers late tonight will turn into a soaking rain Monday into
Tuesday. Strong southwest winds are expected in southeastern
New England and all coastal waters late Monday afternoon and
Monday night. A cold front moves through Tuesday night, and
there might be some snow Tuesday night into Wednesday although
confidence is very low at this point. Dry weather returns late
Wednesday with colder temperatures for Thursday. Another coastal
weather system may bring a mix of precipitation Friday or Saturday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
340 AM update...

Wow...what a frigid start. With clear skies, light wind, and a
snow pack, temperatures dropped to -3 degrees at Orange, MA and
to -6 degrees at Jaffrey, NH as of 3 AM! Single digits
prevailed across most of northern and western MA.

Strong high pressure over southern New England this morning will
move eastward and off the coast by this evening. Skies will be
sunny this morning, then high level cirrus and eventually some
mid level altocumulus clouds will work their way across the sky
late in the afternoon. Although winds will turn to a southerly
direction, they will be light and it will still be a cold day.
Expecting highs only in the lower to mid 30s, except near 40 on
Cape Cod and the Islands.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/...
340 AM update...

Tonight...There is increasing southwestly flow aloft, with a
925 mb low level jet max of 50 knots noted from southeast NH to
eastern ME late. Low level warm advection pattern will cause
temperatures to slowly rise overnight. Low levels saturate
toward daybreak Monday. Low cloudiness develops in CT and
spreads northeastward overnight. SREF shows high probabilities
of ceilings lower than 1000 ft. With increasing moisture in the
low levels but still relatively dry air aloft most of the night,
this spells more of a chance of some drizzle. Actual showers
may develop by 3 or 4 AM. Temperatures in northwest MA could
still be only in the mid 30s, so cannot rule out a few flakes of
snow mixed in with any rain showers there, but it would be very
short-lived. Temperatures should be in the 40s across RI and
southeast MA by daybreak Monday.

Monday...
** Rain and Wind **

Warm advection on strong south to southwest winds will lead to a
rain, with embbeded heavier showers, across the entire region on
Monday. Expecting 1 to 1.75 inches of rain before Monday night,
when additional rain will occur (see below). A very strong low
level jet will be working its way from the NJ coast to Long
Island during the morning, reaching southern RI and the southeast
MA coast very late in the afternoon. The NAM has been the
strongest, with 80-90 kt at 2000 ft whereas other models are
more like 60-70 kt. The big question is how much will mix down
to the surface. This is tough because temperatures will soar to
the mid and upper 50s in southeast MA and southern RI. That,
combined with forecast lapse rates of 6C/km in the 925-700 mb
layer, would make it likely that at least half would reach the
surface. That would translate to wind gusts of 40-50 mph by 4 or
5 PM on Cape Cod and the Islands. Since the bulk of the winds
would be Monday night, have held off on a Wind Advisory at this
point, but either a Wind Advisory or High Wind Watches or
Warnings may be issued later today. We have already issued Gale
Warnings for all coastal waters...mariners take note.

Coincident with the arrival of the aforementioned low level jet,
an isolated rumble of thunder cannot be ruled out along the
south coast toward evening.

Even in northwest MA, temperatures will rise into the lower 50s,
which will melt much of the remaining snow. Per discussions
yesterday, there is 1 to 2 inches of water equivalent in the
snowpack, which, when added to the falling rain, could lead to
rises in river levels, but we are not expecting river flooding
at this time. There will, however, likely be some urban and poor
drainage flooding.

&&

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
Big Picture...

Broad upper trough digs over the Plains and Great Lakes Monday night
and Tuesday while an upper ridge sits over the Western Atlantic.
This creates a southwest flow aloft across the Eastern USA and
brings milder air into Southern New England. The upper trough moves
east midweek, crossing New England Thursday. Less agreement on the
pattern for Friday-Saturday, but possibly a trough digs over the
Plains, then sweeps east to New England over next weekend.

Above normal 500-mb heights Tuesday fall below normal Thursday-
Friday before increasing again on Saturday. So the deep layer is
expected to be mild Tuesday, then falling below normal late week
with signs of a recovery by Saturday.

Mass fields and thermal fields in the models are similar through
midweek but then show some model-to-model differences late in the
week. This means moderate confidence through Tuesday, then
diminishing to low confidence by Friday and Saturday.

Daily Concerns...

Monday night-Tuesday...

Two features of note Monday night. One is a strong southerly low-
level jet moving up the coast over Southern New England. This
provides an inflow of moisture with PW values between 1 and 1.25
inches as well as low level forcing and lift. The second is a strong
150-kt upper jet moving east from the Plains and eventually curving
up over Southern New England. The left exit region of this jet moves
over us Monday evening and night, also generating lift. Temperatures
will be above freezing through the lowest 10 thousand feet, so high
confidence the precip type will be rain/showers.

Low level south to southwest winds reach 60 kt within a couple of
thousand feet of the surface, with highest values just offshore.
Lapse rates will be near moist adiabatic in a shower-filled warm
sector. Expect strong wind gusts to be brought to the surface, with
gusts of 35 to 45 kt. Values similar to this are forecast at 1000 mb.
Thus expect strong gusty winds Monday night and Tuesday.

Guidance also suggests the precipitation comes in two segments: one
Monday night followed by a break Tuesday morning and then a second
segment of rain/showers late Tuesday and Tuesday night. Total
rainfall during this time will be roughly 1 to 2 inches.

Temperatures in the warm sector are indicated by 12C temps at 950
mb. If we have a lapse rate close to isothermal at night, expect
nightime min temps in the lows to mid 50s. A similar temperature
aloft with a dry adiabatic lapse to the surface would suggest
max temps around 60 during the day Tuesday. Will show upper 50s
and around 60 in the coastal plain, and mid 50s in
Western/Central MA

Tuesday night...

Cold front sweeps through Southern New England Tuesday evening and
early night. After it moves through, indications are that it turns
parallel to the upper flow just as we move under the right entrance
region of the upper jet. This should keep the front nearby
overnight and maintain support for precipitation much of the
night. With colder air moving in aloft, this may mean a
changeover to snow with potential of a couple of inches. Cross
sections show the deep column of moisture dries out by 12Z
Wednesday, suggesting a diminishing chance of snow by sunrise.

Wednesday-Thursday...

Upper trough and associated cold pool move across New England on
Wednesday. This should push any lingering precipitation offshore.
Cold pool instability may generate some clouds and scattered
rain/snow showers during Wednesday, with best potential in Western
and Central MA and areas north of the MA border.

High pressure then builds in with cold and dry weather Thursday.

Friday-Saturday...

GFS shows another coastal system moving up from the south Friday,
spreading precipitation into Southern New England with continues
into Saturday.  The ECMWF is slower with the coastal system, moving
precipitation ashore on Saturday. GFS temperatures are borderline,
with potential for both rain and snow. The ECMWF temperature show
predominently rain. Expect a mix of precipitation on one or both
of the days, but with low confidence.
