Synopsis for massachusetts and rhode island coastal waters.. A frontal boundary S of the waters will remain nearly stationary tonight through Fri. A series of weak low pres waves moving along this boundary will bring rounds of showers from time time tonight thru Fri, with embedded heavy downpours and possibly a few tstms. The last wave of low pres exits E of the waters Fri afternoon, afterwhich high pres builds in from the W Fri night and Sat.

Synopsis
Weak high pressure builds over the region providing dry weather
this evening. Then a stalled frontal boundary south of new
england begins to lift north overnight with low clouds, areas of
fog and scattered showers overspreading the region after
midnight. Low pressure will track along this front Tuesday
resulting in periods of rain, possibly tapering off late in the
day. A stronger low may impact the region late Thursday into
Friday with widespread rain and embedded thunderstorms and
downpours possible. Dry conditions return next weekend with a
warming trend Sunday into Monday.

Near term through Tuesday
345 pm update...

short wave energy and associated deep layer moisture from ms oh
valley trough begins to advect eastward tonight. Any showers should
hold off until midnight or after. Models agree on two short waves
impacting the region tonight and tue, however models differ on
amplitude of each wave. Thus forecast uncertainty here with hi res
guidance having stronger lift and deep layer moisture associated
with lead wave 06z-12z tonight, followed by a possible drying trend
tue afternoon. Meanwhile global guidance stronger with second wave
Tuesday and keeps threat of rain throughout the morning and
afternoon.

Could be some periods of heavy rain as pwats climb to near 2 inches
late tonight into Tuesday. Highest threat for heavy rain likely
across ct ri and south of the mass pike.

Short wave induces weak low pressure tracking south of new england
yielding onshore winds into southern new england. This will result
in dew pts rising from the 50s into the 60s tonight. Therefore a
mild night ahead.

Tuesday the combination of onshore flow and showers especially in
the morning along with overcast conditions will limit high temps to
the upper 60s and lower 70s.

Short term Tuesday night
Regardless of model solution, a drying trend should develop tue
night behind departing trailing short wave. Not much of an
airmass change so expect lows in the upper 50s to lower 60s.

Long term Wednesday through Monday
Highlights...

* a few showers possible wed, but mostly dry conditions
* showers and a few t-storms with locally heavy rain late thu
into fri
* drying out for the weekend with a warming trend Sun into mon
overview...

high amplitude pattern developing across canada through the end of
the week and into the weekend, but models differ on some of the
details. Omega block across central canada with persistent closed
low across eastern canada which eventually slides east of new eng
this weekend. This will be preceded by a robust shortwave Thu night
into Fri which will bring a period of wet weather then some
improvement into the weekend.

Wednesday...

generally zonal flow aloft with weak boundary south of new eng.

Deeper moisture and higher pwats south of new eng on Wed and models
are indicating a wedge of drier air from the east across sne. This
is reflected in ki and theta-e fields. With with no organized area
of forcing, expect mostly dry conditions although can't rule out a
few showers along the south coast and in western new eng along the
edge of the higher moisture. Some breaks of Sun expected but
considerable low level rh suggests more clouds than sun.

Thursday into Friday...

robust shortwave for this time of year approaches from the west on
thu moving into new eng late Thu night into fri. Ahead of the
shortwave, anomalous pwats approaching 2 inches move into sne.

Attending sfc low deepening below 1000 mb expected to track near the
south coast. Strong forcing for ascent combined with high pwats and
elevated instability will bring periods of showers and scattered t-
storms with locally heavy rainfall. Timing of heaviest rainfall
appears to be Thu night into early fri, but showers and a few t-
storms may develop Thu afternoon within low level theta-e ridge
axis. Near seasonable temps Thu but below normal Fri behind
departing surface wave.

Saturday into Monday...

mid level trough amplifies east of new eng Sat before lifting out.

Gfs might be too quick moving the trough to the east so leaned
closer to ECMWF solution. The weekend looks dry but will have to
watch a possible shortwave and sfc low cutting to the south of new
eng Sunday. Sat will be the cooler of the weekend days with sne
under influence of cyclonic flow and cooler temps aloft. Then
warming trend Sun into Mon as heights rise and some ridging aloft
moves in from the west. Some showers t-storms possible Mon as
moisture and instability increases ahead of next cold front.
