Area forecast discussion, Nov 28, 9:29 PM EST, 5 hours 5 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
929 PM EST Sat Nov 28 2020
.SYNOPSIS...
Clouds continue to clear overnight. Plenty of sunshine is
expected for Sunday. Strong low pressure lifts through the Mid
Atlantic on Monday. This will bring the potential for strong to
possibly damaging winds and heavy rain Monday and Monday night.
Above normal temperatures early in the week trend seasonably
cold midweek, then normal late week.
&&
.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
930 PM Update...
Large high pressure building south of the region will continue
to result in mainly clear skies/light winds tonight. This will
allow for decent radiational cooling conditions and chillier
temperatures than the last two nights. Lows should bottom out in
the upper 20s to the middle 30s by daybreak, although a bit
milder along the southeast New England coast where winds will
not decouple.
&&
.SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/...
Sunday...
High pressure builds in allowing for a mostly sunny end to
Thanksgiving weekend - perfect weather for any late fall yard
clean up. Seasonable temperatures are expected in the low and
middle 50s across most of southern New England. The one
exception will be those living along the higher terrain of
western Massachusetts - there temperatures might not make it out
of the middle and upper 40s. High pressure allows for light west
winds generally less than 7 knots.
Sunday night...
High pressure will move east of Nova Scotia. Expecting increasing
cloud cover ahead of our next weather player. Increased cloud
cover will keep temperatures a tad warmer than Saturday night.
Low temperatures will generally be in the 30s, but there will be
some mid to upper 40 degree readings along the coastal plain.
While the night will be mostly dry a robust system will be
moving up from the Mid-Atlantic for Monday. A few showers could
start as early as 4am to 6am.
&&
.LONG TERM /MONDAY THROUGH SATURDAY/...
Big Picture...
Merging of northern/southern shortwaves creates a closed low over
the Midwest Monday, turning the upper flow along the East Coast from
the south and drawing up plenty of moisture from the Gulf of Mex.
Closed low lingers to our west through Tuesday, then migrates north
into Canada, where it continues to affect our weather through
Friday. Shortwave over the Pac Northwest coast evolves into another
Midwest closed low by Friday-Saturday.
Contour heights at 500 mb look near normal for Dec 1 most of the
long term period. Heights are lower/colder than normal for Wednesday
as the upper low moves past.
Mass fields are similar in handling the first Midwest closed low,
but continue to show differences in the end of week closed low.
Forecast confidence is moderate-high through Thursday, then low
confidence Friday-Saturday.
Details...
Monday...
Developing Midwest closed low aloft and southerly flow along the
east coast will draw surface low pressure up the Appalachians into
Central NY. The low brings a slug of moisture north with it.
Precipitable water values reach 1 to 1.25 inches per the GFS and
1.25 to 1.5 inches per the NAM. Either is above normal, with the NAM
values being near maximum values for the date. Strong low level jet
is also noted, with both GFS and ECMWF forecasting 60-70 kt at 925
mb late Monday and Monday night.
Expect Monday to feature increasing clouds with rain showers
developing toward midday and local downpours late in the day and at
night, including right around the time of evening rush hour. South
to southeast surface winds increase through the day, and expect wind
gusts 35 to 45 kt in the late afternoon and at night. This may
eventually require a Wind Advisory, but too soon for that at this
time. Best chance of the wind and rain will be in RI and Ern Mass,
including the Central Hills. Finally, convective parameters show a
brief increase Monday evening/night with Total-totals in the upper
40s to around 50 and Lifted Index near zero. This suggests a chance
of thunder during the evening/early night. Expect showers to
diminish around midnight. The low level jet pulls out to the
northeast at that time, so winds should then diminish overnight.
A second shortwave rotates around the upper low and across New
England Tuesday. Expect a second period of showers during the day,
although with a little less wind from the south-southwest.
Overall rain totals for this storm are expected in the 1.5 to
2.5 inch range.
With shallow mixing, we used the 950-mb temps of 10-14C to generate
max temps each day. Highs will be in the upper 50s and lower 60s,
with Monday night mins in the 50s.
Tuesday night through Thursday...
The passage of the second shortwave will swing a cold front through
the region late Tuesday/Tuesday night, with colder air pouring in
during Tuesday night. Showers will end, and temperatures will drop
into the 30s overnight.
Cyclonic flow around the upper low will linger Wednesday and
Thursday. The upper cold pool and associated moisture will generate
a period of clouds Wednesday but no showers. The upper low and cold
pool move off to the northeast Thursday, so diminishing clouds,
while temperatures struggle to reach near normal. Mixing to 900-mb
generating max sfc temps in the 40s to around 50 each day, possibly
a couple of degrees milder Thursday.
Friday-Saturday...
Surface high pressure maintains dry weather Friday. The second
Midwest closed low takes control at that time and feeds another area
of lift and burst of moisture up the east coast. Expect increasing
clouds Saturday morning with rain late Saturday or Saturday night.

Wednesday: VFR. Windy with local gusts up to 30 kt.
Wednesday Night through Thursday: VFR. Breezy.
&&
.MARINE...
Tonight...High Confidence. A weak cold front will result in NW
wind gusts increasing into the lower 20 knots tonight. We opted
to keep conditions just below SCA thresholds with seas in the
open waters mainly between 3 and 4 feet and gusts below 23kts.
Sunday...High Confidence. High pressure centered to our south will
keep winds/seas below small craft advisory thresholds.
Outlook /Monday through Thursday/...
Monday: Moderate risk for gale force winds with gusts up to 45
kt. Local rough seas. Chance of rain showers. Local visibility 1
to 3 nm. Gale Watch has been issued.
Monday Night: Moderate risk for gale force winds with local
gusts up to 45 kt. Rough seas up to 16 ft. Rain showers, slight
chance of thunderstorms. Visibility 1 to 3 nm.
Tuesday: Low risk for gale force winds with gusts up to 40 kt.
Rough seas up to 16 ft. Rain showers.
Tuesday Night: Moderate risk for Small Craft Advisory winds
with gusts up to 30 kt. Rough seas up to 17 ft. Chance of rain
showers.
Wednesday: Moderate risk for Small Craft Advisory winds with
gusts up to 30 kt. Rough seas up to 14 ft.
Wednesday Night: Moderate risk for Small Craft Advisory winds
with gusts up to 25 kt. Rough seas up to 10 ft.
Thursday: Moderate risk for Small Craft Advisory winds with
gusts up to 25 kt. Areas of rough seas.
&&
.TIDES/COASTAL FLOODING...
Increasing southeast wind Monday with gusts around 40 kt
possible. Winds turn more from the south or southwest Monday
night and Tuesday. This will drive the seas up against
southern-facing coasts and may generate splashover in those
areas. Working against this is the relatively low astronomical
tide levels...the max tides were in mid November and next in mid
December.
Nonetheless, guidance suggests some South Coast locations just
below flood stage Monday afternoon and Tuesday. This will need
to be monitored.
