Area Forecast Discussion
National Weather Service Taunton MA
353 PM EDT Wed Aug 2 2017

.SYNOPSIS...
Scattered afternoon showers and thunderstorms are expected today
containing threats of heavy rain, gusty winds, and hail up to an
inch. Flash flooding is possible with heavy rain and slow moving
storms. A FLASH FLOOD WATCH is in effect. Scattered shower and
thunderstorm activity continues through the week. A cold front
will cross the region Saturday that may bring another round of
scattered showers and thunderstorms. A few strong storms are
possible. Behind the front, expect splendid late summer
conditions on Sunday with low humidity. Unsettled weather may
return early next week in the form of more scattered showers and
thunderstorms.

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
330 pm update...

*/ Highlights...

 - FLASH FLOOD WATCH in effect for areas N/W of Providence RI to
   Plymouth MA, roughly Route 44.

 - Slow moving thunderstorms presently ongoing, embedded heavy
   rain threats with rainfall rates of around 2-3 inches an hour

 - Main threat of heavy rain and localized flooding with
   expected slow storm movement.

 - Additional threats of gusty winds and hail up to an inch with
   any of the stronger storms.

*/ Discussion...

Storms impacting S New England. Numerous observations of rainfall
rates of around 2-3 inches an hour contributing to flash flooding
as storm movement has been nearly stationary, in some instances
back-building given the marginal shear environment supporting
multi-cellular storms with cold pool outflows. With higher lofted
cores, more likely impacts of large hail up to an inch and wind
gusts to 50 mph. These threats are likely to continue into the
evening hours by which point they are expected to dissipate with
the lack of daytime heating.

To reiterate...

Main threat will be heavy rain and localized flooding given the
very moist environment and slow movement of storms, as well as
the convective nature of the environment to be pulse- to multi-
cellular convection. Rainfall rates around 2-3 inches per hour
over one particular area, which has already been observed in
spots, contributing to flash flooding.

Secondary threats of hail up to an inch and damaging wind threats
with any cores that are able to be lofted high that immediately
come down.

Given wind and shear profiles, storm-associated cold pools are not
maintaining with some of the storms. Getting a lot of boundary
collisions across S New England, the confluence of which is
contributing to storm maintenance or initiation. This in addition
to daytime mixing. As has been stated earlier, as the energy within
the boundary layer becomes exhausted and the sun goes down, should
see convective activity dissipate.

Tonight...

Convection dissipating into evening, low clouds fill in overnight.
Anticipating with partial clearing after the storms and continued
light wind profile with abundant low-level moisture, that as a
result of nocturnal cooling, low clouds and fog should develop.
Higher confidence for those areas with higher dewpoints across
the interior, specifically the lower CT-River Valley and SE New
England. This as low drop down into the mid to upper 60s.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
Thursday...

Scattered showers and thunderstorms mainly over N/W MA and CT.
Low clouds and fog dissipating during the morning hours with the
early-August sun. Anticipating the burn-off towards the SE coast,
low clouds lingering the longest in and around the Newport RI to
New Bedford MA region. Heights rising within the mid-upper levels
out ahead of a stronger vortmax in associated with deeper mid-
level troughing across the Great Lakes Region. A bit more of a
cap across the region, limiting shower and thunderstorm activity,
however given the moist, unstable environment still in place,
some activity is expected, the area of greatest threat to the
N/W away from the more onshore, stable marine air, mainly atop
the high terrain with anabatic, convergent flow up the slopes.
Heavy rain the main threat given the weak shear and mean wind
profile. Storms likely once again to be the pulse-type and slow
moving given the weak steering flow.

Thursday night...

Convection dissipating again, expect the return of low clouds and
fog. Clearing into the evening, anticipating that all the low clouds
along the S-shore dissipated or become scattered, given the low
level moist profile and nocturnal cooling, low clouds and fog develop
once again. Higher dewpoint air over much of the region, feel there
is a risk of low clouds and fog over a majority of S New England.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...

Highlights...

* Typical summer warmth and humidity Friday and Saturday
* Scattered afternoon and evening showers/thunderstorms Friday
* Another round of showers/thunderstorms with a cold front during
  Saturday, a few may be strong
* Heat and humidity break Sat night into early next week

Overview...

Main H5 steering pattern across continues to signal an eastern
Pacific/Alaska high amplitude ridge with responding downstream
trough from broad cutoff H5 low across Hudson/James Bays through
Ontario to the mid Mississippi valley. Will start off with S-SW
winds and warm, humid conditions. With cold front well W of the
region, may see diurnal showers/thunderstorms during Fri across
central and western areas. The upper pattern remains relatively
progressive, so models continue to signal cold front moving
steadily E during Sat, but appears most of the energy will
remain N of the region as the short wave swings NE across
upstate NY into Quebec.

As the short wave lifts out of the region late this weekend,
generally a mainly zonal flow will bring dry and briefly cool
conditions. Another short wave may push E-NE across the Great
Lakes early next week. A weak surface reflection may push E, but
timing and track are in question due to wide model solution
spread. Overall, however, pattern looks to remain progressive
through the middle of next week.

Details...

Friday...
With broad, diffluent SW flow aloft, the cold front should
remain well W of the region closer to the mid level trough. Also
noting low pressure off the mid Atlantic coast which should
slowly pass well SE of the region. With general instability
across the region, expect scattered afternoon/evening showers
and thunderstorms to develop. PWATs generally 1.5 to 1.7 inches,
so may see some locally heavy downpours. Scattered showers may
linger Fri night across central and western areas ahead of
approaching front.

SW winds gusting up to around 20-25 mph along the S coast. Away
from the S coast, temps will top off in the lower-mid 80s.

Saturday-Saturday night...
Cold front steadily pushes E during this timeframe. Best shot
for showers/thunderstorms will occur during the day Sat,
especially across western areas where likely POPs remain in
place, with scattered activity further E. Good instability
noted, with SLIs from zero to -2 and K indices in the lower 30s.
Also noting PWATs in the 1.7 to 1.8 inch range across western
areas, so may see spotty heavy downpours during the day.

Back edge of precip should push E starting Sat evening across
the CT valley, with a few lingering thunderstorms through around
midnight across the E. Expect improving conditions after 06Z-
08Z across E Mass/RI as drier air works in.

Sunday-Monday...
Cold front well offshore by Sunday morning, then broad high
pressure works in. This will be cooler conditions especially
across the interior. H85 temps will be down to +10C to +12C
Sunday morning, coolest across the E slopes of the Berkshires
where high temps will only reach to around 70 (about 10 degrees
below normal). Temps will range to 75-80 across the coastal
plain.

On Monday, the high will shift offshore in fast nearly
progressive mid level flow. Some question on timing of next
approaching low, with leading edge may push into western areas
Mon night.

Tuesday-Wednesday...
Low confidence for Tuesday as low pressure may pass across the
region. Carrying chance POPs for now with timing and exact track
issues in place. Low may push offshore by Tue night, then
another high may approach Wed. For now, have continued with
below normal temps both Tue and Wed.

.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
Forecaster Confidence Levels...

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

Short Term /through Thursday Night/...

Rest of today...
SCT SHRA/TSRA ongoing N/W of PVD-GHG, will continue into evening.
A FLASH FLOOD WATCH is in effect. +RA definite along with MVFR-
IFR impacts. Also expecting gusty winds radiating outwards from
storm centers. Continue TEMPO wording VRB15G25KT. Stronger storms
will also contain a risk of hail. Otherwise, breezy S winds with
possible gusts near 20 kts for SE coastal terminals.

Wednesday night...Moderate confidence.
SHRA/TSRA dissipate after sunset. VFR mostly however expect IFR-
LIFR CIGs and VSBYs to develop once again. Higher confidence for
the lower CT-River Valley and interior SE New England terminals.
Light S winds overall.

Thursday...Moderate confidence.
IFR-LIFR CIGs and VSBYs erode towards the S-coast, lingering
possibly into the midday hours for places like UUU-EWB. SCT
SHRA/TSRA develop over the N/W interior, mainly across the high
terrain. TEMPO MVFR-IFR with any wet-weather. Otherwise VFR with
breezy S winds, gusts up to 20 kts.

Thursday night...Moderate confidence.
SCT SHRA/TSRA dissipate into evening. VFR initially again but
expect IFR-LIFR CIGs and VSBYs to develop, more widespread over
S New England terminals into Friday morning. Light S winds.

KBOS Terminal...TSRA impacting the terminal, winds are VRB at this
time. Should see as activity dissipates into evening that winds
return more S. For now, present activity will result in MVFR-IFR
impacts and the continuation of airport weather warnings.

KBDL Terminal...TSRA impacting the terminal, winds are VRB at this
time. Should see as activity dissipates into evening that winds
return more S. For now, present activity will result in MVFR-IFR
impacts and the continuation of airport weather warnings.

Outlook /Friday through Monday/...

Friday...High confidence.
Mainly VFR. May see sct SHRA/TSRA across N central and western
areas Fri afternoon/evening, then taper back to SHRA across the
CT valley Fri night. Patchy late night/early morning fog with
local MVFR-IFR VSBYS.

Saturday...Moderate to high confidence.
Sct-numerous showers/sct TSRA with local MVFR-IFR conditions.
Some +SHRA possible over central and western areas through early
afternoon. Leftover patchy early morning fog. Light S-SW winds
shift to W across central and western areas Sat afternoon.

Saturday night-Sunday...Moderate confidence.
Leftover SHRA/TSRA over central and eastern areas Sat evening,
should push offshore by 04Z-05Z. Otherwise, VFR conditions. W-NW
winds 5-10 kt.

Sunday-Monday...Moderate confidence.
VFR conditions Sunday. Scattered showers move from W-E during
Monday, but timing in question. Local MVFR CIGS/VSBYS.
