Area Forecast Discussion
National Weather Service Boston/Norton MA
208 PM EDT Mon Aug 24 2020

.SYNOPSIS...

Warm and humid conditions to continue through Tuesday.
Scattered thunderstorms are expected to develop again today, a
few of which may become strong to severe. Thunderstorms may be
more numerous on Tuesday ahead of a strong cold front, and those
may also become strong to severe. Dry, autumn feel across
southern New England on Wednesday. Unsettled pattern returns
late in the week and heading into the weekend with temperatures
trending upward.

&&

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

2 PM Update...

* Scattered strong-severe thunderstorms into early evening
  especially near and south of the MA Turnpike

Scattered strong to severe thunderstorms were beginning to
develop across southern New England. SPC Meso-Analysis is
indicating over 3000 J/KG of Cape across southern New England.
This partially a result of modest mid level lapse rates on the
order of 6 C/KM and even a bit higher. Despite marginal
effective shear of 25 knots, the amount of instability will be
enough to trigger scattered strong to severe thunderstorms
into early this evening.

The main threat will be localized damaging wind gusts given
DCape values on the order of 1000 J/KG. However, given modest
mid level lapse rates and a lot of instability the risk exists
for isolated reports of large hail. While the threat for
scattered strong to severe thunderstorms exists across the
entire region, areas near and south of the MA Turnpike have the
highest risk. This is where the best instability/forcing are
aligned.

Lastly, slow moving storms will be capable of producing heavy
rain and localized urban street flooding.

&&

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

Tonight:

Any leftover storms should be weakening and/or moving offshore early
tonight. Should see improving conditions as we move into the
midnight/early-overnight hrs. While generally clear for the
interior, will again see development of patchy fog and/or low
stratus overnight towards the South Coast and the Cape. Lows in
the 60s.

Tuesday:

** Strong to severe thunderstorms capable of gusty winds and hail
possible Tuesday **

While there are some uncertainties and limiting factors, Tuesday
still continues to look quite active. The very warm and humid
conditions presently across Southern New England will continue to
exist ahead of a powerful cold front and related strong mid/upper
level trough to support a risk for strong to severe thunderstorms.
SPC has maintained 15%/Slight Risk severe probabilities for Tuesday,
these probabilities maintained from the earlier Day-3 and Day-4
outlooks.

On the cold front itself, guidance continues to vary on exact timing
of the frontal passage thru Southern New England. This will need
some refining, but at the moment we could be looking at a late-
morning to mid-afternoon frontal passage. Given the strength of the
flow aloft, the front should be hauling fairly quickly through our
area and that may limit how much we can destabilize before the front
arrives. Still, storms which form are expected to get a boost from
strong forcing tied to the digging shortwave trough. With effective-
layer wind shear values around 40-45 kt and most-unstable CAPE
values conservatively around 1500-2000 J/kg, this is an environment
that supports severe weather in the form of gusty/damaging winds and
hail. While straight hodographs and shear values support organized
multicells and splitting-supercell types, the strength of the front
may make it difficult for storms to stay cellular long enough with a
favored linear mode. Though guidance varies on placement of frontal
storms, consistency in SPC's convective forecasts and the
instability/shear and forcing make a compelling argument to include
gusty winds and small hail in the forecast. Stay tuned!

Will again see temperatures rise into the mid to upper 80s on
Tuesday, only slightly cooler than prior days. Will also have
westerly breezes pre-frontal, with a sharp wind shift to northwest
arriving late in the day.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...

Highlights

* Will feel like autumn on Wednesday as a Canadian high nudges into
  the region.

* Appears unsettled late in the week and heading into the weekend.
  May see drier weather return by Sunday.

Tuesday night through Wednesday night...

Upper trough slides offshore Tuesday night into early Wednesday,
while a ridge builds from Manitoba into northern Ontario. The ridge
will keep building into northern Ontario through Wednesday. At the
surface a cold front will be offshore. Behind the front, a Canadian
high will nudge into the region from Ontario/James Bay.

Any leftover showers and thunderstorms will be winding down with the
front offshore. Skies will clear fairly quickly Tuesday evening into
early Wednesday, so could have strong radiational cooling across the
region with plummeting dew points. Have nudged low temperatures
toward the 25th percentile of guidance. Have kept from going cooler
as winds may stay up due to the tight pressure gradient across the
region from the departing front and high nudging in. Lows falling
into the upper 40s across far northwest MA and in the 50s elsewhere.

Will remain breezy across southern New England on Wednesday with the
tightened pressure gradient in place. Will be a big change from the
past couple of days with an autumn like feel and very comfortable
with dew points in the 40s to low 50s. Aloft will see 4 to 8 degree
Celsius cold air advection. This results in high temperatures in the
lower to middle 70s across the region. There may perhaps be a few
upper 70 degree readings across the CT River Valley being aided by
W/WNW downsloping at 925 hPa.

Wednesday night through Sunday...

Confidence in the forecast significantly diminishes during this
timeframe. The majority of Wednesday night into Thursday morning
will be dry, but there are hints that a decaying thunderstorm
complex slides southeastward into southern New England or the Mid
Atlantic for Thursday from the central Great Lakes. Given that this
is 48+ hours out and outside the window of CAMs (this complex would
have origins in the Upper Mississippi River Valley), have kept a
blended model approach. This keeps southern New England under slight
chance to chances of precipitation. Will need to see how things
evolve upstream in future updates, but there is a few hundred J/kg
of MUCAPE in place along with 45-50+ kts of 0-6 km shear.

Do expect temperatures and dew points to rise as flow becomes more W
to WSW aloft. Will be slightly warmer with readings in the mid to
upper 70s. Should still be comfortable with dew points in the 50s,
though southern portions of the region may creep into the lower 60s.

Lots of spread amongst guidance from Thursday through Saturday as
the remnants of Laura get pulled into the upper flow late in the
week. This may interact with a trough digging into the Great Lakes,
but there are timing and amplitude differences in the strength of
the trough. As stated earlier, appears that it will remain unsettled
with rain chances Friday and Saturday. May see a ridge build into
Ontario on Sunday and provide drier weather.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
Forecaster Confidence Levels...

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

18Z Update...

This Afternoon...Moderate confidence.

Scattered SHRA/TSRA will continue into early this evening with
areal coverage the greatest near and south of the MA Turnpike.
So while VFR conditions dominate, localized pockets of IFR-LIFR
conditions possible in any strong thunderstorms. Localized
strong wind gusts possible too. Low clouds/fog should mainly be
confined to ACK and parts of the Cape.

Tonight...Moderate confidence.

Scattered SHRA/TSRA should be winding down towards 00z, but can
not rule out a bit of activity lingering an hour or two longer.
Otherwise, VFR much of the evening but patchy ground fog may
develop late in the typically prone locations. Low clouds should
be confined to ACK and perhaps near the south coast and Cape
Cod. Light SW winds.

Tuesday...Moderate confidence.

Patchy ground fog should burnoff by mid morning, yielding mainly
VFR conditions. The main concern will be Tuesday afternoon and
evening with the potential for a few strong thunderstorms. Some
uncertainty on areal coverage, but a few may result in strong
wind gusts.

Tuesday night...High confidence.

Any left over convection should wind down early in the evening.
Otherwise, VFR with NW winds of 5 to 15 knots with some 20 to 25
knot gusts expected across portions of the coastal plain.

KBOS Terminal...Moderate confidence in TAF. Main concern is the
threat for scattered thunderstorms in the vicinity of the
terminal until about 00z.

KBDL Terminal...Moderate confidence in TAF. Main concern is the
threat for scattered thunderstorms in the vicinity of the
terminal until about 00z.

Outlook /Tuesday Night through Friday/...

Wednesday: VFR. Breezy.

Wednesday Night: Mainly VFR, with local MVFR possible.

Thursday: Mainly MVFR, with areas VFR possible. Breezy. Chance
SHRA, slight chance TSRA.

Thursday Night: Mainly VFR, with areas MVFR possible. Slight
chance SHRA, slight chance TSRA.

Friday: Mainly MVFR, with areas VFR possible. Chance SHRA.

&&

.MARINE...
730 AM Update...

Fog and stratus will linger across the ocean waters through
today and into tonight. Some locations may see the fog/stratus
burn off, but think overall most areas will remain socked in per
high res guidance.

Previous discussion...

Winds and seas on the waters to be below small craft advisory
thresholds. Gusts under 20 kt today from the SW with seas under 3'.
On Tuesday, strengthening low-level winds ahead of a strong cold
front could support borderline SCA gusts on the southern waters with
seas in the 3 to 4' range.

Areas of fog to dissipate over the waters early this morning, though
another round of fog/stratus is anticipated again tonight. Fog may
be locally dense at times. Thunderstorms, some strong, may threaten
the waters today but a better potential is on Tuesday.

Looking ahead, we may need to consider marine headlines into
Wednesday due to strong NW winds behind the cold front.

Outlook /Tuesday Night through Friday/...

Tuesday Night: Winds less than 25 kt. Seas up to 5 ft.

Wednesday through Wednesday Night: Winds less than 25 kt. Seas
locally approaching 5 ft.

Thursday: Winds less than 25 kt. Seas locally approaching 5 ft.
Chance of rain showers, slight chance of thunderstorms.

Thursday Night: Winds less than 25 kt. Chance of rain showers,
slight chance of thunderstorms.

Friday: Winds less than 25 kt. Chance of rain showers.
