Special Weather Statement, NWS Boston/Norton, MA

Area Forecast Discussion
National Weather Service Taunton MA
501 PM EDT THU AUG 11 2016

.SYNOPSIS...

Excessive heat and humidity will affect much of the region
through Saturday before temperatures lower slightly early next
week. A few showers or thunderstorms are possible today and
Friday, mainly in western New England. Rounds of showers and
thunderstorms with locally heavy, much needed rainfall, are likely
through the weekend. Showers and possibly a few thunderstorms may
linger into next week as a stubborn nearly stationary front
remains close to or just south of the region.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
345 pm update...

With the heat and humidity across the region, instability has
built substantially. Focused especially in those areas with robust
available sub-tropical moisture, mainly S/W portions of New England
encompassing CT, RI, and S/W MA when you evaluate precipitable
waters from SPC mesoanalysis. Continued focus on H925-7 Q-vector
convergence coupled with diurnal heating able to break any cap
aloft around H85 across the region. Little mid to upper level
support, so still believe most activity will mainly consist of
heavy rain, absent of lightning, but as we have already seen
today, some of the storms take on an environment of their own and
blossom considerably. Trends continue the next few hours then go
downward as we progress into evening, in thinking. Continued heavy
rain wording and monitoring storms closely with their slower
motion potentially posing an urban and poor-drainage flooding.

Tonight...

Humidity the main story. Increasing SW flow per an isallobaric
response ahead of synoptics emerging out of the Great Lakes
Region. Dewpoints maintaining in the low to mid 70s overnight as
temperatures fall to values just a few degrees above. Monitoring
closely dewpoint values observed during max heating earlier today.
Looking for cross-over thresholds. In all, low clouds and dense
fog appear to be an issue, in combination when looking at ensemble
probabalistic guidance, over the Cape and Islands and perhaps
within sheltered valleys within the CT River Valley. Could see
areas of fog with visibilities down to a mile in places. Perhaps a
repeat of Wednesday night into Thursday morning.

Otherwise, shower and thunderstorm activity. Thinking that activity
weakens S/E though maintains given continued low level signals of
Q-vector convergence coupled with a low level inflow of sub-tropical
air. It's possible that activity maintains towards sunrise and
have trended this accordingly with chance PoPs in the forecast grids.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/...
Friday into Friday Night...

 - Heat advisories for much of S New England
 - Showers and thunderstorms possible late in the day

First off, heat rebuilds as humidity maintains. Expect a near-
repeat of heat index values across S New England. Rather than
getting cute with the hazard, evaluated it from a lay-persons
perspective. While some areas may not heat advisory-level
criteria, felt the successive day of heat and humidity warranted
the advisory to be posted over the same area as it was today.

Secondly, expected later-half of the day shower and thunderstorm
impacts. Strong mid-level impulse traversing W to E through the H5
quasi-zonal flow. Main show is over Northern NE CONUS with strong
low to mid level convergence, nearly deep-layer forcing, and decent
venting aloft. This along an accompanying surface cold front.
Thinking is that given the instability and environment that some
diurnally / orographically driven scattered activity develops
initially across S New England around midday into afternoon.
Otherwise expect upstream activity along a cold front over Upstate
NY and N New England to develop around midday and move S/E into S
New England towards evening.

Main concern is heavy rain given the abundance of moisture and the
parallel flow to the front. There is the possibility of some training
storms over one particular area with the W to E flow parallel with
the anticipated cold frontal boundary. NCAR ensembles exhibit decent
probabilistics when it comes to rainfall in a short period of
time. Not entirely confidence on one particular area, but
something to watch. Low confidence at this time to handle with any
headlines so will go with a mention in the Hazardous Weather
Outlook.

As to the evening and overnight period, anticipating activity to
remain ongoing, pushing S/E with the mean-layer flow, fueled from
the SW by sub-tropical moisture. More interestingly are the
indications of a back-door cold front dropping in towards morning
seemingly in response to mid-level energy traversing across the
region W to E and an isallobaric response. Low confidence at this
time and these sort of situations are tricky to pin down. A big
wrench in the forecast for the overnight period.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
HIGHLIGHTS...

* Hazy and hot conditions continue this weekend with heat
  headlines likely on Saturday

* Potential for rounds of showers and thunderstorms with heavy
  rainfall and a localized urban flood threat Saturday into
  Monday

* Lingering front could keep shower potential around into the mid
  and latter portion of next week

OVERVIEW...

Overall upper level pattern remains persistent with nearly
stationary Bermuda high pressure off the eastern seaboard through
most if not all of this timeframe. Tropical moisture will rotate
around the periphery of this high, interacting with a stationary
front in the nearly zonal flow aloft across New England to bring
periods of heavy rainfall. Weak waves on this front, and short
waves aloft, will bring periods of showers and thunderstorms
through the weekend into early next week.

With 12Z models signaling wide solution spread beyond Monday,
will be difficult to pinpoint the exact location, timing and
duration of any potential heavy rainfall. We have fairly good
confidence during the Sunday-Monday timeframe, with
showers/thunderstorms at times. On Monday, looks like low pressure
forms on another front across NY state. The big question here is
how far S will it move as the low crosses the region on Monday.
Right now, appears that the front will stall S of the region,
which will keep threat for showers in place though not a lot of
moisture to work with as somewhat drier air tries to slip in.

With the high humidities in place, as dewpoints hold in the
lower-mid 70s into this weekend, temperatures will not fall much
especially in urban centers at least Saturday and Sunday nights.
Record high minimum temperatures may be tied or set.

DETAILS...

Saturday...Moderate Confidence.

Stalled front draped across northern New England as low pressure
moves along it. Moisture pumping in around the western edge of the
Bermuda high, with PWATS up to 2.2 to 2.5 inches, will see
showers/ thunderstorms anywhere across the region. Looks like the
best shot will be near and N of the Mass Pike. Noting CAPES up to
1100-1500 j/kg, K indices in the upper 30s and LIs from zero to
-2. Have kept chance to likely POPs going. May see heavy rainfall
in any activity, which may produce localized flooding.

With the high humidity in place, and high temps reaching the mid
80s to mid 90s, heat indices will likely reach close to 105
degrees at some locations. Heat headlines will likely be needed.
Models continue to try and bring down a backdoor front of sorts,
which will make temps along the E Mass coast tricky. Looks like
highest readings will occur across the interior Merrimack valley
as well as the Conn valley.

Sunday and Monday...Moderate Confidence.

Nearly stationary front across northern New England will slowly
sag south during this timeframe. Models continue to signal low
pressure forming on this front, which will enhance the threat for
showers/ thunderstorms, mainly Sunday afternoon and night. PWATs
remain high, on order of 2.2 to 2.4 inches, so threat for heavy
rainfall and localized flooding continues. Still have lowered
confidence due to model spread on the timing of the low and front.
At this point, the low should move to the E of New England Monday
morning.

Temperatures will remain warm on Sunday, though not quite as high
as on Saturday, then turning a bit cooler Monday. Dewpoints will
remain high especially across south coastal areas before the front
finally passes.

Tuesday through Thursday...Low confidence.

With the front remaining close to our just south of the region
while sitting in the persistent H5 nearly zonal flow across the
northeast during this timeframe. Looks like the threat for showers
will linger, though surface system is weak and not a lot of
moisture convergence. 12Z models are starting to signal a weak H5
short wave in the flow that may try to kick the front far enough S
to end the light precip around the late Wednesday or Wednesday
night timeframe. Wide model solution variance, so this has quite a
bit of uncertainty.

&&

.AVIATION /21Z THURSDAY THROUGH TUESDAY/...
Forecaster Confidence Levels.

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

Short Term /through Friday Night/...

Rest of Today...High confidence.
SHRA/TSRA over S/W MA, CT, RI into early evening with TEMPO MVFR-
IFR conditions. IFR-LIFR lingers over the Cape and Islands, making
a return into the evening hours.

Tonight...Moderate confidence.
SHRA/TSRA activity dissipates. SW winds on the increase. Confidence
of patchy fog conditions in the sheltered areas of the CT Valley
especially wherever RA may have occurred earlier. Areas of fog and
low clouds impacting the Cape and Islands, thinking developing
during the evening period and persisting into Friday morning. Low
confidence on specifics.

Friday...Moderate confidence.
MVFR-LIFR may linger over the Cape and Islands. Attention shifts
across the interior as SHRA/TSRA are expected over Upstate NY into
N New England around midday shifting S/E into S New England into
the later-half of the day. TEMPO MVFR-IFR possible with any wx. SW
winds continue.

Friday night...Moderate confidence.
SHRA/TSRA may linger into the evening period but expect activity
to diminish around midnight. Low-end VFR conditions lingering with
the possibility of MVFR-LIFR down towards the Cape and Islands.

KBOS Terminal...Moderate confidence. Will hold SW winds throughout
and keep RA/TSRA out of the terminal.

KBDL Terminal...Moderate confidence. SCT SHRA/TSRA around the
terminal through the early evening hours.

Outlook /Saturday through Tuesday/...

High confidence in restrictions to CIGS/VSBYS, but moderate
confidence on exact timing of the conditions.

Saturday-Sunday...Expect showers/scattered thunderstorms at any
point during the day. Looks like best chance for MVFR-IFR
CIGS/VSBYS will occur near and N of the Mass Pike. Locally heavy
rainfall in any thunderstorms will also reduce VSBYS. Low
clouds/areas of fog after 01Z-02Z will reduce CIGS/VSBYS each
night, with LIFR conditions likely across coastal terminals, which
should improve to VFR mid-late morning each day.

Monday-Tuesday...Low clouds/fog with MVFR-IFR conditions early
each morning, which should improve to mainly VFR by mid-late
morning. Will still see showers/scattered thunderstorms Monday
morning, then threat for convection lessens from N-S during the
afternoon though showers will linger especially near and S of the
Mass Pike. Will see patchy MVFR-IFR CIGS/VSBYS in any
showers/thunderstorms. A few thunderstorms may linger near the S
coast Tuesday night.

&&

.MARINE...
Forecaster Confidence Levels.

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

Short Term /through Friday Night/...High confidence.

Increasing SW flow ahead of an area of disturbed weather for late
Friday into Friday night. Will see gusts up to around 25 kts
lending to stress over the waters generating waves up to 5 feet.
Small craft advisories posted accordingly.

Moderate confidence at this time that some shower and thunderstorm
activity will impact the waters overnight tonight, but a dissipating
trend is anticipated. Greater confidence of wet-weather impacts
is forecasted for the Friday night into Saturday morning timeframe.
It is during both these periods that there will also be the
accompanying possibility of dense fog at times with visibilities
significantly reduced, possible down to a mile or less.

Outlook /Saturday through Tuesday/...

Moderate confidence in trends with low confidence on exact
timing.

Saturday-Sunday...Mainly S-SW winds gusting to 20 kt on the
southern outer waters Saturday. Seas up to 5 ft on the southern
waters, mainly in swells. Visibility restrictions in areas of
nighttime and early morning fog, and in showers/thunderstorms at
times.

Monday-Tuesday...S-SW winds continue but will gradually diminish.
Seas mainly below 5 ft both days. May still see scattered showers/
thunderstorms at times with reduced visibilities. Patchy fog will
also reduce visibilities during each late night/early morning
period.
