.WHAT HAS CHANGED...
Small Craft Advisory remains in effect for the southern waters
through at least tomorrow morning.

&&

.KEY MESSAGES...

- Scattered showers tapering off tonight. Mainly dry conditions
  Wednesday with scattered showers and storms arriving overnight
  into Thursday. 

- Still unsettled Thursday with showers and thunderstorms, with a 
  low chance that some storms could become strong. 

- Mix of clouds and sun with diurnally driven spot showers
  Friday into the early part of Labor Day Weekend, but drier
  weather most of the time. Dry and seasonable Sunday and on the
  Monday holiday, with onshore breezes.

.DISCUSSION...
KEY MESSAGE 1...Scattered showers tapering off tonight. Mainly
dry conditions Wednesday with scattered showers and storms 
arriving overnight into Thursday. 

Expect scattered showers for the remainder of the afternoon, 
decreasing in coverage this evening as higher pressure builds in 
from the west. Can't rule out a few isolated showers overnight, 
otherwise most locations remain dry. 

High pressure remains in place Wednesday supporting mainly dry 
conditions with temperatures in the upper 60s and low 70s. A surface 
low pressure system tracks across Canada bringing a series of fronts 
across the region later Wednesday through Thursday. A warm front 
pushes into southern New England Wednesday night accompanied by 
advection of a plume of above normal moisture. Precipitable water 
values rise to 1-1.8" overnight. Lift provided by the jet positioned 
to the west and warm front will support the return of showers and 
perhaps some embedded storms. There is uncertainty regarding the 
finer details such as timing and thunderstorm probabilities due
to spread across model guidance. Showers/storms more likely 
arrive in west and central portions of southern New England 11 
PM to 2 AM arriving in the I-95 corridor 09-12Z. There are 
indications of marginal elevated instability that accompanies 
the plume of richer moisture. This may support a few embedded 
thunderstorms. This has been reflected across the simulated 
reflectivity in the high-res guidance, some more aggressive than
others. This has led to lower confidence on how widespread 
embedded storms/heavy downpours will be. Steering flow appears 
strong enough to support quicker storm motion which would limit 
the risk for flash flooding. If there are embedded storms and 
downpours, can't rule out the potential for poor drainage/urban 
flooding in the more vulnerable spots.

KEY MESSAGE 2...Still unsettled Thursday with showers and thunderstorms,
with a low chance that some storms could become strong. 

Carrying over from Wednesday night is a continued risk for showers 
and thunderstorms into Thursday, as a stronger shortwave impulse 
moves through. The main question mark is on if storms could become 
strong in this timeframe. Although the airmass is plenty humid and 
mid and upper level wind fields are seasonably strong, considerable 
cloud cover could temper how much destabilization occurs. GFS-
based CAPE profiles show about 800-1600 J/kg of most-unstable 
CAPE with moist-adiabatic mid-level lapse rates also tempering 
instability. It's still debatable if storms could become strong 
but the chances seem low with more tempered instability favored.
Still, Thursday looks to be a washout with good chances for 
rains during the daytime hours, with more substantial clearing 
taking place Thursday evening.

KEY MESSAGE 3...Mix of clouds and sun with diurnally driven spot showers
Friday into the early part of Labor Day Weekend, but drier 
weather most of the time. Dry and seasonable Sunday and on the 
Monday holiday, with onshore breezes.

Still under cyclonic flow aloft for Friday into the early part of 
Labor Day Weekend. This will keep weather pattern somewhat unsettled 
with a mix of clouds and sun. Spot showers are possible Friday 
and Saturday afternoon but drier weather prevails most of the 
time. much of the time. Broad high pressure then works in from 
the north Sunday into Labor Day, leading to onshore breezes, but
with partly sunny skies and dry conditions.

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
Forecaster Confidence Levels...

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

00z TAF Update: 

Tonight: Moderate to high confidence. 

Lowest categories tonight (MVFR-IFR) should be confined to
PVD/ORH line westward under moist ESE flow; this is where
categories are currently the lowest and should stay that way
into the Wednesday early morning period. MVFR-VFR categories for
BED, BOS and the Cape and Islands should trend BKN/OVC VFR for
much of the overnight. Light E/SE winds. 

Wednesday...High confidence.

VFR after 15z, however, mid-level clouds remain throughout the day. 
Easterly to east-southeasterly wind prevail. 

Wednesday Night...High confidence in trends, moderate confidence in 
timing. 

Showers returning overnight with embedded thunder, ceilings lowering 
to IFR/LIFR. Southeast winds. 

KBOS Terminal...High confidence in TAF. BKN/OVC VFR
ceilings/visbys with light ESE winds tonight. MVFR ceilings
return around or after 00z Thursday.

KBDL Terminal...Moderate confidence in TAF. MVFR-IFR in stratus
and mist, not likely to improve until mid morning Wednesday, 
then VFR. MVFR ceilings return around or after 00z Thursday.

Outlook /Wednesday Night through Sunday/...

Thursday: Mainly VFR, with local IFR possible. Breezy. SHRA
likely, chance TSRA.

Thursday Night: VFR. Chance SHRA.

Friday through Friday Night: VFR. 

Saturday: VFR. Breezy. Slight chance SHRA.

Saturday Night through Sunday: VFR. Breezy.

.MARINE...
Forecaster Confidence Levels...

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

Through Wednesday Night...High confidence.

Scattered showers across the water this afternoon and evening, a
few showers moderate at times. Low chance for an embedded
thunderstorm. Easterly flow less than 25 kts across the eastern
waters. There is potential for a period of SCA gusts (~25 kts)
this evening and overnight for the southern waters tonight with
seas 3-5 ft. A SCA is in effect for the southern waters through
Wednesday morning. It is possible this may need to be extended
if 5 ft seas linger across southern outer waters off Block
Island Wednesday. 

Outlook /Wednesday Night through Sunday/...

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

Thursday Night: Winds less than 25 kt. Seas locally approaching
5 ft. 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: Winds less than 25 kt. Areas of seas approaching
5 ft. 

Saturday Night: Low risk for Small Craft Advisory winds with
gusts up to 25 kt. Local rough seas. 

Sunday: Low risk for Small Craft Advisory winds with gusts up
to 25 kt. Areas of rough seas.
