Area Forecast Discussion
National Weather Service Boston/Norton MA
1006 AM EDT Wed Jul 17 2019

.SYNOPSIS...

A cold front will approach the region later today, with the
threat of scattered showers and thunderstorms, along with the
potential of heavy rainfall. As the front pushes across tonight,
the remnants of Barry with bring more showers with locally
heavy rainfall, along with scattered thunderstorms which will
continue through most of Thursday. Hot and humid conditions
settle in for Friday through Sunday with heat related headlines
likely. A cold front sweeps through the region Monday with
scattered showers and thunderstorm. High pressure then builds
over New England Tuesday bringing seasonable temperatures and
much lower humidity.

&&

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

1005 am update...

* A few strong-severe t-storms possible this afternoon into this
  evening along with a heavy rain/localized flood threat

An abundance of clouds were in place at mid morning across
southern New England along with a few spot showers. There was also a
small cluster of brief heavy showers and thunderstorms near the
southern RI coast.

This isolated activity at mid morning have developed in the
warm air advection pattern. However, the main show is expected
this afternoon into this evening as scattered showers and
thunderstorms develop ahead of an approaching cold front. While
clouds have limited heating this morning, we were starting to
see some breaks develop across the interior. This should allow
high temperatures to reach the upper 80s in many locales with a
few lower 90s also possible. Dewpoints of 70+ should generate
1500 to 2500 J/KG of Cape this afternoon. The big limiting
factor will be poor mid level lapse rates which will likely keep
this from being a widespread severe weather event. However,
with shear increasing to between 30 and 35 knots with 70+
dewpoints a few strong to severe thunderstorms are certainly
possible with localized damaging wind gusts the main concern. In
fact, an isolated wet microburst is also possible in this
environment. In addition...Pwats of 2+ inches will result
torrential rainfall with any thunderstorms and bring the threat
for localized flooding.

So in a nutshell...while a widespread severe weather event is
unlikely a few strong to severe thunderstorms are certainly
possible. The high Pwat atmosphere will be ripe for localized 1
to 2 inch per hour rainfall amounts and bring the risk for
localized flooding.

Lastly...the high dewpoint airmass will result in heat indices
reaching the middle 90s this afternoon. In fact, its not out of
the question that a few spots see heat indices into the upper
90s to near 100.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
* A few strong to severe thunderstorms possible this evening
* Heavy rainfall with localized urban & poor drainage flooding
  possible this evening through Thursday

Tonight and Thursday...

The front will slowly shift S into the region tonight as the
mid level steering flow becomes nearly zonal. Will see winds
shift to E-NE across N Mass mainly around midnight or so. Will
continue to see the threat of thunderstorms that may produce
gusty to possibly damaging winds through around 02Z, then should
subside somewhat.

However, the threat for heavy rainfall that may produce local
urban/poor drainage flooding will continue, focusing on N CT/RI
and SE Mass where the best moisture convergence and feed will be
situated. Most short range high res models bring the bullseye
of heavy rainfall across this portion of the region. Along with
this, the nearly zonal flow will bring the remnants of Barry
across central and southern areas overnight through midday
Thursday, enhancing the rainfall even more.

Current forecast QPF amounts could be from 1.5 to 2.5 inches
from this afternoon through Thursday, mainly from the Mass Pike
southward.

With E-NE winds behind the slowly moving cold front, low level
moisture will feed off the ocean, allowing the precip to linger
through the majority of Thursday from S of Boston across SE
Mass into RI and NE CT, but should see some diminishing precip
further N and W during the afternoon.

Highs on Thursday will mainly be in the 70s.

&&

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

Zonal flow across the northern half of the USA while subtropical
high pressure controls the southern half. Remnants of Barry in the
zonal flow will move east of Southern New England by Friday. Early
next week the subtropical high builds north over the Western USA,
while a trough digs over the Northeast USA.

Normal 500-mb heights for mid July are 580 to 582 Dm. Forecast
heights build to 591 Dm over the weekend, then trend to normal or a
little lower early next week as the upper trough digs in. From this,
we expect above-normal temperatures Friday-Saturday-Sunday, then
expect warmer than normal temperatures through the weekend, then a
trend to near normal temperatures early next week.

General agreement among the model mass and thermal fields through
the weekend. The fields early next week show a similar general
pattern with small differences. Overall forecast confidence is
moderate-high, but confidence in timing of the cold fronts Sunday-
Monday is low-moderate.

Concerns...

Thursday night and Friday...

Remnants of Barry pass south of Southern New England Thursday night.
Winds are initially from the east and northeast, then turn from the
north after the remnants move past. The east flow is a wet pattern
is a wet pattern, especially in Eastern MA and potentially in
Central MA and RI. Expect continued showers and scattered
thunderstorms the first half of the night, diminishing to no
precipitation in Western MA and Northern CT after midnight. PW
values remain at 2 inches or more across RI and Eastern MA the first
half of the night, then diminish overnight. This means continued
potential for downpours in this area through midnight, then
diminishing showers after midnight.

Cross sections show lingering low-level moisture for clouds over all
of the region Friday morning. So expect clouds to start Friday, and
possibly some drizzle or widely scattered showers in Coastal MA
Friday morning. But expect drying at cloud-level and warming temps
aloft suppressing further shower development...700 mb temps climb
above 10C...and so we should see clearing during the day. With dew
points in the 60s, expect min temps Thursday night in the 60s.
Increasing sun Friday will allow mixing to 850 mb, tapping
temperatures of 18-20C which would support max sfc temps of upper
80s to mid 90s. We bumped guidance values up 3-5F to line up this
these values.  The temperatures and humidity will generate heat
index values in the 90s.

Friday night through Sunday...

High pressure builds surface and aloft, cresting over Southern New
England Saturday and then pulling south on Sunday. Temps at 700 mb
crest about 13C Saturday, which should suppress anything that tries
to form a shower. PW values fluctuate, but stay close to 2 inches
through the weekend. So the airmass will have a good supply of
moisture in it and surface dew points 70F to 75F. With dew points at
that level, expect overnight min temps Friday night and Saturday
night will be in the 70s to near 80, warm and muggy both nights.
Mixing to 850 mb will tap temperatures of 21-23C, supporting max sfc
temps of 95-100F. Heat index values will be above 100F most places
and above 105F in some inland areas.

Sunday starts quite warm aloft, but with the relaxing ridge we
should see temps aloft lowering with time. Temps at 700 mb start the
day above 10C, but lower just below by late in the day. This heat
dome should suppress convection for at least the first half of the
day. The question is whether the heat aloft diminishes enough to
allow showers/tstms later in the day. Best chance for this would be
across the northern half of Massachusetts. We have chance pops in
this northern area during the afternoon/evening. Temps at 850 mb are
forecast at 20-22C, which translates to another day well into the
90s at the surface. This brings the heat index to 95-100, similar to
Friday.

Monday-Tuesday...

Cold front sweeps south from Canada Monday, with potential for
showers/tstms. PW values linger between 1.5 and 2 inches until the
front moves through, showing potential for downpours. High
pressure then moves in behind the front Tuesday, bringing rain-
free and less humid air.

&&

.AVIATION /14Z 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/...Moderate confidence.

Today...

VFR conditions will dominate outside of scattered showers and
thunderstorms mainly this afternoon and evening. However, some
IFR conditions in low clouds may impact the southeast New
England coast at times, especially this morning as high dewpoint
air continues to stream into the region.

Isolated showers mainly across southeast New England at mid
morning with a small cluster of embedded thunderstorms across
near the southwest RI coast. Broader area of showers/thunder
over Western NY and Western PA will approach our area during the
afternoon and into the evening. Additional SCT SHRA/Isold TSRA
will develop from N-S during the day, some that may produce +RA
and possibly gusty winds. IFR- LIFR conditions with any +RA.
Lower confidence on exact timing of impacts. W-SW winds 5-10 kt,
gusting up to 20 kt at times along the S coast. SCT-BKN CIGs
becoming OVC late.

Tonight...
SCT-LKLY SHRA/CHC TSRA through most of the night. Continued +RA
threat with IFR-LIFR conditions. W-SW winds 10 kt or less,
shifting to E-NE from Cape Ann around 04Z S to near outer Cape
Cod toward daybreak. CIGS lowering to IFR-LIFR with local IFR
VSBYS in patchy fog along the S coast, Cape Cod and the islands
and possibly into the CT valley around or after midnight. OVC
conditions overall.

Thursday...
CAT SHRA across NE CT/RI/S coastal Mass Thu morning, with LKLY
SHRA mainly near/S of the Mass Pike along with SCT TSRA.
Conditions slowly improve, but SCT SHRA/Isold TSRA may linger
inland, with better shot for SHRA/TSRA across E Mass/RI with
onshore flow lingering. E-NE winds around 10 kt with some gusts
up to 20 kt along E coastal terminals.

KBOS Terminal...
High TAF confidence this morning, then moderate confidence this
afternoon and tonight. May see a few TSRA this afternoon and
evening, along with possible +RA and gusty winds.

KBDL Terminal...
High TAF confidence this morning, then moderate confidence
this afternoon and tonight. Main concern will be for a few VCTS
this afternoon into tonight with possible +RA and gusty winds.

Outlook /Thursday Night through Sunday/...High confidence.

Thursday Night: Mainly VFR, with local IFR possible. Slight
chance SHRA.

Friday through Saturday Night: VFR.

Sunday: VFR. Slight chance SHRA.

&&

.MARINE...
Forecaster Confidence Levels...

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

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

Today...
High pressure pushes further offshore this morning. Meanwhile, a
cold front approaches from the St Lawrence Valley. This will
result in SW winds of 10 to 15 knots with gusts up to 20 knots
across the southern waters. However, both wind gusts and seas
should remain below small craft advisory thresholds. Potential
for a few strong thunderstorms with localized strong winds later
today into this evening, especially across the near shore
waters.

Tonight...
A cold front will push S during the night, with SW winds
shifting to E-NE across the eastern waters to outer Cape Cod,
but will remain SW across the southern waters. Showers and
isolated thunderstorms continue, which will be locally heavy at
times. Areas of fog develop, mainly across the southern near
shore waters to E of Cape Cod.

Thursday...
Winds gradually shift to E-SE across the southern waters during
the day, with E-NE winds 10-15 kt across the eastern waters.
Gusts up to 20 kt Thu morning on the eastern waters. Threat for
showers with locally heavy rainfall, along with a few
thunderstorms continues mainly from about Boston Harbor
southward, though will start to diminish during the afternoon.

Outlook /Thursday Night through Sunday/...High confidence.

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

Friday: Winds less than 25 kt.

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

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

Sunday: Winds less than 25 kt.

...A FEW STRONG TO SEVERE THUNDERSTORMS ALONG WITH A LOCALIZED
FLOOD THREAT EXIST THIS AFTERNOON AND EVENING...

A cold front approaching southern New England will result in
scattered showers and thunderstorms developing around mid
afternoon persisting into the first part of the evening. A few of
the thunderstorms may become strong to severe and produce
isolated/localized wind damage. In addition...torrential rain may
result in 1 to 2 inch per hour rainfall rates with the stronger
thunderstorms. This may result in localized flooding, particularly
if the activity occurs over urbanized centers. Lastly...these
thunderstorms are expected to contain dangerous cloud to ground
lightning.

Please keep an eye and if you have outdoor plans be prepared to
seek an indoor shelter if threatening weather approaches.
