Area Forecast Discussion
National Weather Service Taunton MA
727 AM EDT Wed Sep 6 2017

.SYNOPSIS...
A slow moving cold front will push farther east today and tonight,
bringing showers and embedded thunderstorms with the threat for
localized flash flooding.  The cold front then moves offshore
Thursday, followed by drier and seasonably cool weather into the
weekend, then warming on Monday and Tuesday of next week.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
*** Localized flash flooding possible Today & Tonight ***

7 am update...
Some modest convection has fired this morning along an axis of
weak convergence within a very moist airmass ahead of a slowing
cold front in NY. This first wave will shift out of the region
this morning, but given the approaching front, providing more
convergence for the afternoon. Will maintain POPs through the
day as they stand, given guidance is not handling this first
round well. On/off SHRA and isolated TSRA will be the status
quo through the day until stronger frontal wave arrives tonight
given conditionally unstable soundings.

Previous discussion follows...

Watching an area of convection with cooling cloud tops south of
Block Island. This is associated with the first of several
impulses/jet-speed maxes within the amplifying warm conveyor belt
along the eastern seaboard. These wind anomalies of +2 to +3
standard deviations above climo will act on an airmass characterized
by PWATs of 1.6 to 1.7 inches this morning. This will be sufficient
to generate localized heavy downpours with the focused this morning
across southeast MA including Cape Cod and the islands.

Second area for potential heavy rain today especially this afternoon
will be farther west across CT into western-central MA associated
with a slow moving cold front entering the area. Main forcing
mechanism here will be strong low level frontal convergence within a
subtropical airmass. Thus locally heavy downpours are possible here
as well.

Other concern today is a very low prob for a few strong T-storms in
the high shear/low cape environment. Area of interest is across
eastern MA where models projecting CAPES up to 1000 j/kg. This
instability coupled with strengthening low level jet, low LCLs and
high dew pts provides some support for potential rotating storms.

Otherwise expecting a warm and muggy day with temps in the 70s and
dew pts well into the 60s to near 70.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
Tonight...

Appears most impressive low level jet and moisture plume pushes
across the region 03z to 09z from south to north. The 00z ECMWF
advects PWATs up to 2.3 inches across southern New England
overnight. This combination of strong wind anomalies acting on
anomalous moisture plume along with strong frontal convergence. Thus
flash flood threat continues across RI and eastern MA into the
Worcester Hills. Threat exist westward into CT and western-central
MA, however bulk of the guidance including the 00z NCAR ensembles
simulate heaviest rainfall across RI and eastern MA.

Another warm and muggy night as most of the region remains in the
warm sector.

Thursday...

Any heavy rain showers/T-storms early Thu morning will be confined
to RI and eastern MA and will move offshore rapidly from west to
east as dry slot races eastward across the area. However some of
this early morning heavy rain could impact the morning commute.
Breaks of sunshine likely develop during the afternoon given rapidly
drying thru the column as negative K indices overspread the region.
Seasonably warm with highs in the 70s.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Overview and model preferences...
Meridional pattern remains in place across the CONUS through
the end of the week, especially as lifting trof (which is
currently nearly 4 std deviations deeper than climatology)
shifts into the Maritimes in response to building ridge. The
ridge building likely somewhat due to interaction from Irma,
which yields a rather complex scenario, however am continuing to
note rather good synoptic agreement that the mean trof base
will be E of S New England, suggesting drier air from upstream
ridging will dominate sensible wx details in spite of the
cyclonic curvature to the flow. Beyond the weekend, after
influence from this trof has shifted E, agree with the previous
forecaster that a quick moving shortwave currently wrapped in
the Aleutian vortex will be the next to watch as it could
interact with the remnants of Irma. Given that there continues
to be at least moderate agreement through the weekend in the
synoptic pattern, will maintain the consensus blend.

Details...

Fri into Sat...
The combination of enhanced CAA and a little bit of trapped
moisture beneath a dry will allow two weak shortwaves, rotating
through the slowly lifting longwave trof across New England to
yield predominantly diurnally driven SHRA and cloud cover both
Fri and Sat. H5 temps drop to an average of -20C leading to SLIs
near 0, TT in the 50s and moderate mid-lvl lapse rates each
afternoon. POPs and skies will reflect this thinking, peaking
late afternoon each day. Far from a washout, just mainly a few
showers to dodge. H85 temps continue cooling, from around +5C on
Fri, to between +3C to +4C. Highs each day below normal. W
component to the flow will help, but Fri, low-mid 70s are likely
the warmest, while by Sat, highs will hold in the upper 60s to
low 70s. Afternoon dwpts, mainly upper 40s and low 50s suggest
these are the floor for overnight mins.

Sun and Mon...
Trof shifts E allowing less cyclonic flow and peak influence of
ridging along with 1015hPa high pres, mainly dry conditions
under dry soundings. H85 temps gradually warm as the high pres
crests then shifts E late Sun, averaging about +7C to about +9C
on Mon. Highs likely remain generally below normal as a result,
low 70s Sun followed by mid-upper 70s on Mon. Overnight lows
still comfortable given low dwpts in the upper 40s and low 50s.

Tue through Wed...
Complex scenario given interaction between the wave currently
wrapped up near the Aleutians, which is likely not being sampled
well, and Irma, which still has track errors yet to be
resolved. High pres remains in place initially, but if this wave
properly captures Irma's remnants, this could yield a similar
scenario to Harvey's remnants. Confidence low, especially with
timing or even if high pres could suppress any N motion. Stay
tuned for now.

&&

.AVIATION /12Z 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/...

Today...

Risk of showers and T-storms increase as the day progress with
greatest risk during the afternoon and night. Areas of IFR/MVFR
may give way to some VFR later this morning and afternoon before
categories once again lower late this afternoon and evening. A
few strong storms are possible with brief heavy downpours and
gusty winds.

After 00z...

Scattered showers and T-storms in MVFR conditions. Some of the
rainfall will be intense.

Thursday...lingering MVFR conditions in early morning showers
gives way to afternoon VFR and light winds.

KBOS Terminal..Moderate confidence in TAF.

KBDL Terminal...Moderate confidence in TAF.

Outlook /Thursday Night through Sunday/...

Thursday night...Moderate confidence.
Conditions improve to VFR especially as winds shift to the W.
Gusts to 25 kt linger through the overnight hours.

Friday-Saturday...High confidence.
VFR except early AM fog and some afternoon showers. Winds shift
around to the N and NW.

Sunday...High confidence.
VFR, less likely for SHRA.

&&

.MARINE...
Forecaster Confidence Levels...

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

Short Term /through Thursday/...

Persistent SSW wind 10-15 kt with gust at times up to 25 kt. Vsby
limited in scattered showers/T-storm and fog.

Improvement Thu with wind shift to the west along with sharp
increase in vsby.

Outlook /Thursday Night through Sunday/...

Westerly winds Thu night into Fri remain around 25 kt but then
gradually subside and shift to the NW Sat and Sun, but remaining
at or below 20 kt.

Seas 5-8 ft on the outer waters will gradually subside into Sat,
but may require that some small craft advisories linger until
then.

Quiet boating weather for Sun.
