What's New / NOTES
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Synopsis for massachusetts and rhode island coastal waters.. A wave of low pres will emerge off the mid atlantic coast tonight and track east northeast across our southern waters on Mon. The low will move away from the region on Tue and be followed by high pres for Wed. The high will move east of our waters by Thu. For information on possible hazardous weather beyond the 24-36 hour forecast period, please visit www.weather.gov/boston and follow the current hazards link above the map on the left.

Synopsis
Rain moves off the s-coast this morning behind which conditions
improve. Partly cloudy with near-seasonable temperatures. Cooler,
damp conditions are forecast for Monday and Tuesday. High pressure
in control will bring dry and pleasant weather Wednesday and
probably into much of Thursday. Another low pressure system will
likely bring showers isolated thunderstorms to the region Thursday
night and or Friday, perhaps lingering into Saturday. Temperatures
will be below normal for most if not all of the coming week.

Near term until 6 pm this evening
4 am update...

an improving trend. Weak wave low is passing to our S along a quasi-
stationary frontal boundary roughly W to E off the nj coast. SW flow
of sub-tropical moisture ascending along and ahead, per latest radar,
a widespread area of rain that is flirting with the immediate S coast.

Have adjusted pops according. Should see this area of rain clear out
during the early morning hours. Clouds diminishing, anticipate partly
cloudy conditions beneath a cooler airmass aloft resulting in highs
around the upper 70s to low 80s. E onshore winds contributing to
cooler conditions along the coast, perhaps gusting up around 20 to
25 kts immediately behind the aforementioned low for a brief period
of time early this morning. Comfortable overall in comparison to
days past. Dewpoints dropping overnight and will continue to do
so with the N E winds during the day, some places falling into
the upper 40s with daytime mixing.

Short term 6 pm this evening through Tuesday night
Tonight through Tuesday night...

a prolonged period of cool, damp weather. Potent open wave h5 trough
sweeps through the region Monday night into Tuesday. In advance, an
interior surface low emerges Sunday night over the E great lakes,
transferring energy towards the coast and offshore across regions
of better baroclinicity Monday. Per an isallobaric response, a wedge
of high pressure settles in- between brought about by stout NE flow.

More stable, cooler airmass via a cold air damming setup, amplified
as the interior surface low weakens across the W foothills of the
appalachains Monday night and the low offshore deepens. Reminiscent
of winter, atypical as is the amplified trough pattern for mid-summer.

An over-running setup. The kinked frontal pattern across the region
with cooler, more stable air, will keep better thunderstorm chances
well S W throughout the forecast, though can't rule out some rumbles
of thunder over S W portions of new england with possible elevated
instability. Nothing strong to severe. Main concern is with torrential
rainfall. Period of heavy rain given available forcing upon deepest,
most pronounced column moisture is forecast Monday with collocation
of sub-tropical moisture influx undergoing lift along the kinked
frontal boundary beneath some weaker ascent associated with lead
shortwave energy. Will need to watch closely upon low-level convergent
winds to the front. The rest of the timeframe looks to be cool and
damp, especially Monday night into Tuesday as the mid-level dynamics
sweep the region with stronger mid- level forcing acting upon remnant,
available moisture, though more continental rather than sub-tropical.

Light showery weather is to be expected along with an abundance of
low clouds, perhaps some patchy fog.

Clearing out Tuesday night in wake of the h5 trough. Subsidence
prevailing as cooler, drier air settles S brought in by N flow
becoming light with increasing high pressure up to around 1025.

As model solutions vary, especially with respect to the magnitude
of low level convergent forcing along the frontal profile from the
ne with the GEFS suggesting +3-4 standard deviation above normal
and both the ec NAM hinting at least a 30 mph inflow, will keep it
conservative and keep close to the latest SREF output. Upstream
convective elements transitioning along the quasi-stationary boundary
s at the start of the forecast period late Sunday into Sunday night,
indications of mesoscale convective systems across pa and ny, but
then it would appear the pattern across the NE CONUS becomes more
synoptic with energy pinwheeling.

Chance to likely pops, highest Monday. Will hint at the chance of
thunder towards SW ct Monday. No special wording just yet on heavy
rain given the uncertainty and low confidence spatially as to where
heavy rain will occur.

Long term Wednesday through Saturday
Highlights...

* dry and pleasant Wed and probably into much of Thu afternoon
* unsettled wet weather likely returns by Thu night and or fri
* temps will remain below normal through the end of the week
details...

Wednesday into Thursday afternoon...

high pressure will build across the region Wed and slide east of our
area by thu. The result will be dry weather Wed and probably into
most of Thu afternoon. Temperatures should rebound from early in
the week, but still average a bit below normal for late july. Highs
should mainly be in the middle 70s to lower 80s Wed and Thu afternoons
with comfortable humidity.

Thursday night through Saturday...

a rather impressive shortwave for late july will dive southeastward
from the great lakes and carve out another northeast trough. The
approaching shortwave will likely bring a period of showers and
perhaps isolated thunderstorms to the region. Specific timing is
uncertain with most guidance currently focused on Thu night fri,
but it is possible some activity lingers into sat. Temps should
remain below normal with highs mainly in the 70s to the lower 80s.

Kbos terminal...VFR. Strong E flow developing this morning. Will
hold gusts up to 20 kts but not out of the question to see gusts

Monday morning.

High - greater than 60 percent.

Short term through Tuesday night ...

today...

e NE winds to which potentially early this morning there may be
a burst of 20 to 25 kts across the E waters. As of 4a, isle of

feet.

Tonight...

continued E flow with gusts up around 20 kts, as high as 25 kts
along the s-coast forecast. Seas no greater than 4 feet.

widespread rain with embedded heavier showers. Could be some
visibility restrictions out on the waters. Continued breezy NE flow
with gusts up to 25 kts. Seas building to 5 feet on the S SE outer
waters.

Monday night into Tuesday...

MVFR-ifr CIGS linger with -shra dz. Lower conditions possible Monday

especially across E ma. Seas up to 5 feet on the E outer waters.

Tuesday night...

diminishing below 5 feet.

Outlook Wednesday through Thursday ...

Wednesday and Thursday... Moderate confidence.

Winds and seas should remain below small craft thresholds wed
into Thu morning with high pressure in control. As the high
pressure system moves east of the waters, south to southwest
winds may gust to between 20 and 25 knots by Thu afternoon.
