Area Forecast Discussion
National Weather Service Boston/Norton MA
323 PM EDT Mon Sep 21 2020

.SYNOPSIS...
Cooler than normal temperatures continue today with a gradual
warming trend Tuesday. A warming trend follows through the
weekend with above normal temperatures for much of that time.
Hurricane Teddy will pass well east of our coastline Tuesday as
it heads into the Canadian Maritimes. While we will remain dry,
it will bring a period of windy conditions along the coast,
especially Cape Cod and Nantucket where a wind advisory is
posted. Minor coastal flooding and some beach erosion may also
occur during the Tuesday afternoon and early evening high tide.
Otherwise, the prolonged period of dry weather continues right
through the week. An approaching cold front may bring showers
next Monday.

&&

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

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

1030 AM Update...

A strong high continues to plant itself over northern New
England today. Will remain breezy across Cape Cod and the
Islands due to the interaction between the high and distant
Hurricane Teddy southeast of the region.

Have increased high temperatures toward the 75th percentile of
guidance as the current situation is similar to yesterday, and
that performed pretty well. We also were just a touch too cool
compared to the latest obs. In addition, decreased dewpoints
based on the latest observations. The net effect is a drier RH
forecast across the region. Rest of the forecast remains on
track.

7 AM Update...

1038 mb high over northern New England providing a chilly
morning across much of the region. It's a shallow cold airmass
with higher elevations such as Worcester at 47 degs, not nearly
as cold as the valleys with Orange, MA at 29 degs. Also,
northeast winds across coastal Plymouth county, Cape Cod and the
Islands yielding temps only in the 50s at sunrise! Thus a large
range of temps this morning.

Airmass modifies some today so not as cool as yesterday along
with more sunshine helping to offset the cool temps.
Nonetheless highs today of 60-65 will fall short of the normal
highs of low 70s. Previous forecast remains on track so not
planning any major changes with this update. Earlier discussion
below.

===================================================================

* Sunny but still unseasonably cool today

A 1035+ MB high pressure system centered over northern New England
will continue to result in unseasonably cool temperatures today.
After another frosty morning away from the coast and urban centers,
sunny skies will allow for a nice day despite cooler than normal
temperatures. High temperatures should top out mainly in the lower
to middle 60s. A bit of a northeast breeze along the coast and
especially the Cape/Islands where winds will gust between 25 and 30
mph. Nonetheless, not a bad day in the sunshine at least away from
the gusty winds along the southeast New England coast.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/...
* Northerly Wind Gusts of 40-50 mph on Tue across the Cape/Nantucket

* Pockets of Minor Coastal Flooding/Beach Erosion late Tue
  afternoon/early evening along the eastern MA Coast, Cape & Islands

* Dangerously High Surf on Tuesday along ocean exposed beaches

Tonight...

High pressure will remain in control of our weather tonight. The
result will be mainly clear skies and another unseasonably chilly
night for most locations. Light winds inland from the coast will
allow for temperatures to bottom out well down into the 30s across
many locations. Some of the normally coolest locations may drop to
or just below the freezing mark. Additional frost headlines will be
needed where the growing season is still technically active.
Meanwhile, across the Cape/Islands the pressure gradient will be
increasing as a result of distant Hurricane Teddy. This will result
in northeast wind gusts of 20 to 30 mph developing after midnight
across the Cape/Islands and perhaps a bit stronger in Nantucket. The
NE winds blowing off the ocean may hold overnight low temps above 50
in many of these locations.

Tuesday...

Hurricane Teddy will be lifting north across the open Atlantic,
approximately 300 to 400 miles east of our coastline. While no rain
is expected from Teddy in our region, a very strong pressure
gradient will develop with high pressure across northern New
England. Bufkit soundings indicating good mixing on northerly winds
across Cape Cod and Nantucket. Therefore, we are hoisting a Wind
Advisory for the Cape and Nantucket for expected northerly wind
gusts of 40 to 50 mph. There is a low risk Nantucket could flirt
with high wind warning criteria, mainly for a period of sustained 35
knot wind gusts. At this point, we felt a Wind Advisory would be
more representative based on model consensus but something later
shifts will have to monitor.

Across the rest of the region, northerly wind gusts of 20 to 30 mph
with the strongest of those winds towards the coastal plain. Plenty
of sunshine will allow for high temperatures to reach the upper 60s
to the lower 70s.

&&

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...

Big Picture...

Closed circulation associated with Hurricane Teddy moves off to
northeast through Nova Scotia. Northwest flow takes over in New
England Wednesday, then weakens as upper high builds over the
Northeast USA through the weekend. Broad trough moves from the
Pacific Northwest Friday to New England Monday.

Contour heights build starting midweek, trending above normal late
week and then lowering again early next week. This suggests a
warming trend from midweek to the weekend, then cooling early next
week.

Model mass fields are similar through Saturday, then diverge Sunday
and Monday with the approaching shortwave. Forecast confidence is
high Wednesday through Saturday, then lowers to low-moderate by
Monday.

Details...

Tuesday night-Wednesday...

Teddy moves off to the northeast Tuesday night/Wednesday. Main
concerns will be along the coast with leftover winds and coastal
flooding/high surf. The pressure gradient will be less over the
interior, strongest along the MA East Coast. But the trend during
these 24 hours will be toward diminishing gradient and thus
diminishing wind.

A weak shortwave moves through the northwest flow aloft Wednesday.
Cross sections show moisture overhead between 700 mb and 925 mb and
drier air below 925 mb. The limited and shallow moisture underlain
by dry air suggests difficulty for showers. Will indicate some
clouds during Wednesday but otherwise dry weather.

May lower temps for Tuesday night in Western MA/CT due to lighter
winds, otherwise continue with a general range of 45-55. Daytime
mixing on Wednesday will reach to between 850 and 900 mb. Temps at
that level will be 9-10C, supporting sfc max temps in the 70s...mid
to upper 70s in most areas. Northwest winds in the mixed layer will
be near 25 mph.

Wednesday night through Monday...

High pressure builds over the region Thursday, then shifts offshore
Friday and the weekend. This is a dry weather pattern for that
period. There continue to be signs of a weak cold front from Canada
that reaches Northern New England by early Friday. This could bring
clouds and maybe an isolated shower to Southern New England early
Friday. But low probability, so will keep POPs below 15 pct for
now.

Temps at 850 mb will be 12-14C through the period, while 900 mb
temps will be equiv to 9-11C. Will keep max temps a little cooler
than 850 values would suggest. Values in the mid 70s to around 80,
but mostly 70s Sunday-Monday. Expect sea breezes Friday and Saturday
along the Mass East coast. Dew points rise into the 50s for much of
the period, and winds will be light. So min temps should be in the
50s.

Low level flow turns from the south Sunday, which may bring low-
level clouds/drizzle by Sunday night.

The Pacific NW trough approaches Monday, with cross sections showing
brief deep moisture while PW values climb to around 1.75 inches.
Upper jet leading the trough sweeps its right entrance region over
Srn New England, which would add supporting lift to the factors. On
the other hand this is a day 7 forecast and as noted above there is
lower confidence in the Day 7 mass fields. The forecast will
indicate showers for Monday, but with POPs limited to 30-40 pct.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
Forecaster Confidence Levels...

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

Through 00Z...High confidence.

VFR with any gusty NE winds across the interior decoupling.
Coastal locations could see some stratocumulus with cloud bases
around 4 kft. Remains gusty across Cape Cod and the Islands
with a strong pressure gradient in place due to the high over
New England and distant Hurricane Teddy. Gusts of 25-35 kts
across the Cape and Islands.

Tonight...High confidence.

VFR conditions persist. The majority of terminals will see light
NE winds shifting to the N. Cape Cod and the Islands will see
gusty winds persist with winds shifting to the N. Gusts of 25-40
kts.

Tuesday...High confidence.

VFR continues with strong northerly winds. Gusts 20 to 25 knots
across the interior, 25 to 30 knots near and southeast of the
Boston to Providence corridor, and 35 to 45 knots across the
Cape and Nantucket.

Tuesday Night...High confidence.

VFR continues with N winds shifting to the NW. Remaining gusty,
but will see the speeds diminishing as the night progresses.

KBOS Terminal...High confidence in TAF.

KBDL Terminal...High confidence in TAF.

Outlook /Tuesday Night through Saturday/...

Tuesday Night: VFR. Strong winds, mainly Cape Cod and Islands,
with gusts up to 45 kt.

Wednesday: VFR. Breezy.

Wednesday Night through Saturday: VFR.

&&

.MARINE...
* Dangerously High Seas of 15-20+ feet Tue into Tue night for the
  eastern MA coastal waters

* Storm Watches Nantucket Sound points south and east with Gale
  Warnings for most other open waters

Today and tonight...High confidence. High pressure over northern New
England will continue to result in cool advection over the waters.
This should generate NE wind gusts of 20 to 30 knots and perhaps bit
stronger southeast of Nantucket especially later tonight. 7 to 10
foot seas across the open waters.

Tuesday...High confidence. Hurricane Teddy will pass hundreds of
miles east of our waters. That being said, a strong pressure
gradient with high pressure over northern new England will result in
strong Northerly winds and dangerously high seas for mariners. We
opted to go with a Storm Watch Nantucket sound and our outer-waters
east of Provincetown to Nantucket. Northerly wind gusts of 40 to 50
knots with seas reaching 20+ feet. Later shifts can decide if its
worthy of a Storm Warning or convert to a strongly worded Gale
Warning. Across most of our other waters, opted for Gale Warnings
for northerly wind gusts of 30 to 45 knots. This will be a dangerous
storm for mariners, especially in our waters east of the outer-Cape
and Nantucket.

Outlook /Tuesday Night through Saturday/...

Tuesday Night: Low risk for gale force winds with gusts up to
45 kt. Rough seas up to 23 ft.

Wednesday: Low risk for Small Craft Advisory winds with gusts
up to 30 kt. Rough seas up to 15 ft.

Wednesday Night: Winds less than 25 kt. Areas of seas
approaching 5 ft.

Thursday through Saturday: Winds less than 25 kt. Seas less than
5 ft.

&&

.FIRE WEATHER...
1030 AM Update...

Increased high temperatures and lowered dew points at bit across
southern New england. The net effect is minimum relative
humidities lowering to 20 to 30 percent across the interior and
35-45 percent across coastal locations. The rest of the forecast
remains on track.

* Fire Weather Concerns Especially on Tuesday

We continue with the special weather statement for today. The
unusually prolonged stretch of dry weather continues and minimum RH
values will drop to between 25 and 35 percent across much of the
interior and 40 to 45 along the southeast coastline. It will be a
bit gusty near the coastline too.

There are even greater fire weather concerns on Tuesday and it is
possible we may need to consider Fire Weather Headlines. Distant
Hurricane Teddy should generate 20 to 30 mph wind gusts over most
areas but between 40 and 50 mph for Cape Cod and Nantucket. Minimum
RH values will drop to between 20 and 30 percent in most locations
with 35 to 45 percent across the Cape and Islands.

&&

.TIDES/COASTAL FLOODING...
* Coastal Flood Advisory In Effect Tuesday Afternoon/Early Evening

* High Surf/Dangerous Rip Currents especially on Tue

High astronomical MLLW tides of 11.6 feet are on tap for this
afternoon. This may result in splash over and minor pockets of very
minor coastal flooding/beach erosion along the eastern MA coast
given gusty NE winds. Based on this in combination with local
matrices and the Stevens Institute guidance have opted to continue
the Coastal Flood Statement for the eastern MA coastline including
Nantucket.

There is more of a concern on Tuesday as distant Hurricane
Teddy results in some pressure falls and the potential for
northerly wind gusts of 40 to 50 mph across the Cape/Nantucket. This
combined with very highs seas of 15-20+ feet offshore may result in
pockets of minor coastal flooding along the eastern MA coast. This
is especially true on the north facing coastline across Cape Cod Bay
and Nantucket Sound given the wind trajectory will be favorable.
This will likely bring a 1 to 2 foot storm surge. While we are not
expecting a significant/damaging coastal flood event, inundation on
vulnerable shoreline roadways will likely occur within a few hours
of the high tide along with beach erosion. A coastal flood advisory
has been issued for the eastern MA coast, Cape and Islands
for the Tuesday afternoon and early evening high tide.

Lastly, High Surf Advisories remain in place through Tuesday across
all ocean exposed beaches. The worst of the conditions will be on
Tuesday when very high offshore seas may result in extremely high
breakers on beaches. Dangerous rip currents expected too.
