Area Forecast Discussion
National Weather Service Boston/Norton MA
1052 AM EST Wed Dec 4 2019

.SYNOPSIS...
Chilly and unsettled weather is expected through Thursday. A
passing disturbance aloft will increase clouds with some passing
light snow showers or flurries today into early tonight, with
another disturbance aloft passing south of Southern New England
on Thursday. A cold front passing through on Friday with light
snow showers will usher in dry, but unseasonably cold weather
for Saturday. A significant moderation in temperatures occurs
early next week with a period or two of rain Sunday night
through Tuesday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

1030 AM Update...

Mid and high clouds continue to cross the region at midday as
seen on latest GOES-East visible satellite imagery as a mid
level short wave moves across.

Noting spotty light precip on KBOX and NE regional 88D radar
imagery, with a few reports of spotty -SN earlier this morning
across portions of the CT valley as well as the E slopes of the
Berkshires. The precip is moving across dry air in the lower
levels, with dewpoint depressions of 7 to 13 degrees mainly near
and N of the Mass Pike, though a bit lower across N CT/RI/SE
Mass. So, could see some brief, spotty light precip as the weak
mid level trough moves across this afternoon.

Temps were in the lower-mid 30s across most areas at 15Z, except
the upper 30s to lower 40s on the islands with winds off the
milder ocean waters. These readings were pretty close to the
previous forecast.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...

Tonight:

Lead upper level disturbance lifts northward into Quebec, with
another such disturbance right on its heels. However this one
digs southward into the waters south of Long Island by Thursday
morning. Cyclonic flow aloft is maintained across Southern New
England regardless, with light WSW surface winds veering to WNW
through tonight and overnight. A considerable amount of clouds
will remain, with temperatures a bit slower to fall given the
anticipated extent of cloud cover. Could even see some lake
effect flurries late into the east slopes of the Berkshires,
though better potential is on the other side of the ridgeline.
Kept lows in the mid/upper 20s, though lower 20s in the
Berkshires/NW MA.

Thursday:

Another generally weak upper-level disturbance and weak frontal
system will pass to our north. This feature will mainly just
keep mostly to partial cloudiness across the area for the first
part of the day versus produce any precip. Best chance for any
snow showers is mainly to our N and W in lake effect bands.

NWly pressure gradient becomes tighter during the second half
of the day and with cold advection, most areas should turn
breezy/blustery. Looking for gusts in the lower 20s over the
North Shore, but into the 25-30 mph range across northern
CT/northern RI northward into central/western MA, with 30-35 mph
gusts out on the Cape.

Milder lows in the upper 30s to low 40s, with a few low-mid 30s
highs in the Worcester/Tolland hills and into the Berkshires.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...

Big Picture...

Two jet streams, north and south, in a near zonal flow with
shortwaves in each stream moving through the flow. A shortwave ridge
builds over us over the weekend, resolving the split jets into a
single jet which moves up through the Ohio and St Lawrence Valleys
early next week.

Normal 500-mb heights in this area in early December are in the
upper 540s and 550s. Forecast heights are in the 530s and lower 540s
Friday, but moderate to the 560s Sunday and early next week. Expect
cooler than normal deep-layer temps Friday-Saturday, moderating
to above normal temperatures by Monday.

Mass fields and thermal fields in the models are similar through
Monday but show some model-to-model differences next Tuesday. This
means moderate to high forecast confidence through the weekend,
with moderate confidence on Tuesday.

Daily Concerns...

Thursday night...

Upper trough moves off to the east. Surface high pressure builds in
with subsidence and resulting drying. Dew points will be 15-25F with
winds becoming light enough under the high to allow min temps in the
upper teens and 20s.

Friday-Saturday...

Zonal flow prevents any substantial moisture from moving north into
our area.  A shortwave moves east from the Great Lakes, pushing a
cold front across New England Friday night. Moisture cross-sections
show shallow moisture, mainly below 700 mb, and PW values around
0.25 to 0.50 inches. Lift in the moist layer is mediocre. Expect
increasing clouds Friday with a few light snow showers possible. The
front moves off to the east Friday night with winds shifting from
the northwest and clearing skies. Mixing reaches to 925 mb, where
level temps of -4C to -6C support max sfc temps in the 30s. The air
then dries Friday night with dew pts falling to the teens away from
the coast. Temps should fall to 15-25F.

High pressure builds in Saturday with dry air and mixing again to
925 mb. Winds in the mixed layer will be around 20 kt, so expect
gusts to that speed. Temps in the mixed layer will support max sfc
temps in the mid 20s to lower 30s.

A few mid clouds Saturday night, as the leading edge of milder air
moves north above the surface. Colder air lingers at the surface
with readings falling to the teens and lower 20s.

Sunday through Tuesday...

Surface high pressure moves offshore Sunday. Upper shortwave ridge
builds over our area early, then shifts offshore Monday and Tuesday.
This suggests sufficient subsidence for a dry sunny day Sunday. Warm
advection will limit the depth of the mixed layer, but low level
temps aloft support max sfc temps of 35 to 45.

Moisture increases in the developing south-southwest flow aloft
during Sunday afternoon, so expect increasing clouds at that time
and cloudy skies Sunday night through Tuesday. After an evening cool-
down, expect increasing clouds and warm advection to bring rising
temperatures Sunday night. Moisture deepens Monday and Tuesday with
PW values climbing over 1 inch. With the lack of a ridge or
other feature to hold in the cold air, this looks to be
primarily rain. But if the rain moves in before the cold surface
air can be removed, then there could be an initial period of
sleet or freezing rain in Western and North central MA Sunday
night before a change to rain. As this is well in the future, it
will need to be monitored.

&&

.AVIATION /16Z WEDNESDAY THROUGH SUNDAY/...
Forecaster Confidence Levels...

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

Short Term /through Thursday/...High confidence.

Through this afternoon...Mainly VFR conditions. CIGS may lower
to 2500-3000 ft during the afternoon as weak weather system
moves across. May see light snow showers or flurries but not
expected to cause VSBY restrictions.

Tonight through Thursday: Continued BKN/OVC VFR ceilings. W-WSW
winds initially early tonight 5-8 kts become WNW/NW tonight. WNW
winds then increase to 8-12 kts with gusts 20-25 kts Thursday,
near 30 kt towards the Cape.

KBOS Terminal...High confidence in TAF.

KBDL Terminal...High confidence in TAF.

Outlook /Thursday Night through Sunday/...

Thursday Night: VFR. Windy with local gusts up to 30 kt.

Friday: MVFR/IFR conditions possible. Breezy. Chance SHSN.

Friday Night: Mainly VFR, with local IFR possible. Windy with
local gusts up to 30 kt. Slight chance SHSN.

Saturday: VFR. Windy with local gusts up to 30 kt.

Saturday Night through Sunday: VFR. Breezy.

&&

.MARINE...
Short Term /through Thursday/...High confidence.

Small Craft Advisories continue on the outer waters mainly for 5
foot seas, which will subside during the afternoon.

This afternoon...Winds shift to W-SW 10-15 kt with gusts to
around 20 kt early, then will gradually diminish toward evening.
Seas to around 5 ft which will subside during the afternoon.

Tonight...W-SW winds around 10 kts early become northwest
around 10-15 kts, gusts 20-22 kts on southern waters. Seas 2-4
ft.

Thursday...NW winds increase on Thursday. Likely to need small
craft advisories for most waters. Low prob of gale force gusts
southern waters during the afternoon. Seas build to 5-7 ft on
offshore waters, 2-4 ft coastal waters.

Outlook /Thursday Night through Sunday/...

Thursday Night: Low risk for gale force winds with gusts up to
35 kt. Local rough seas.

Friday: Low risk for Small Craft Advisory winds with gusts up
to 30 kt. Areas of seas approaching 5 ft. Chance of rain
showers, chance of snow showers. Local visibility 1 to 3 nm.

Friday Night: Low risk for gale force winds with gusts up to
30 kt. Areas of seas approaching 5 ft. Chance of snow showers.
Visibility 1 to 3 nm.

Saturday: Low risk for gale force winds with gusts up to 30 kt.
