Synopsis for massachusetts and rhode island coastal waters.. A cold front approaches the waters overnight with a few showers and Thunderstorms moving along it through Fri morning, namely across the south coast. The front moves offshore during the day Fri. Canadian high pres builds over the waters Fri and Sat bringing dry weather and less humidity. A stiff northeast wind develops Sun and persists through Tue as the high shifts over the maritimes.

Synopsis
A cold front along the south coast this morning moves well
offshore during the day. Showers along the front will move
offshore with the front. Drier less humid air moves in from the
northwest. Canadian high pressure then provides dry weather
tonight and Saturday with a cool night and a mild afternoon.

Onshore flow Sunday will yield cooler conditions along with a
few showers possible. Cool weather likely lingers into early
next week.

Near term through today
Closed low over quebec with progressive-tilt trough sliding down
over the northeast usa. The flow on the progressive side of the
trough was wsw-ene early this morning, but is forecast to turn
more directly w-e during the day.

North to northwest surface winds at all stations except ack at 2
am. Dew points in the low to mid 50s extend to the mass pike,
with low 70s dew points along the south coast. Based on this, we
would place the cold front at or near the south coast. Further
progress will be slow until the local upper flow turns more w-e
this morning.

Radar shows most showers from mass bay through southern ct to
southcentral pa and moving ene with the upper flow. These will
linger in place until morning, then move offshore as the upper
flow turns.

Once the flow turns as noted above, expect clearing
skies... Soonest in northern ma and latest along the south coast.

Cross sections show drying aloft and at the surface, but a
lingering moist layer around 850 mb. The mixed layer is expected
to reach a little past 850 mb, so there should be some diurnal
cu formation over the interior. The dry air should limit the
extent. Temperatures at 850 mb will be 10-12c, so we expect max
sfc temps of 76f to 82f. Best of all, dew points will be in the
upper 40s and 50s everywhere this afternoon evening.

Short term tonight through 6 pm Saturday
A fair weather period, quite welcome to most after the recent
spell of humidity. High pressure over northern ontario builds
east, reaching the maritimes late Saturday. This brings a light
north flow to new england tonight, turning to a northeast flow
by Saturday afternoon.

With dew points upper 40s and 50s, expect min temps tonight in
the 50s most places... With upper 40s in the cold spots and
around 60 in large urban areas. The developing northeast flow
will play havoc with mixing, but daytime heating and 8c at 850
mb suggest sfc temperatures into the 70s. If anyone stands a
chance at 80, it will be the ct valley of hartford-springfield.

Long term Saturday night through Thursday
4 pm update ...

highlights...

* cooler than normal temperatures expected Sunday and Monday,
with spotty light rain or showers at times
* temperatures moderate by mid week, with another chance for showers
Tuesday through Thursday
details...

Saturday night and Sunday...

the weekend looks overall pleasant and cooler, with a very
comfortably dry airmass in place. A large area of high pressure at
the surface moves east from southern canada into northern new
england and remains anchored there through the weekend. While some
lingering weak troughing and cold pool aloft remain, high pressure
and an especially dry column should keep rain chances to a minimum.

Best chance of some showers will be on Sunday as moist low level
advection increases on north easterly flow which could allow for
some shallow showers... Can't rule out a pop up shower for most of
the region but the best chance would be along the south and east
coasts and coastal plain. Speaking of northeasterly flow around that
surface high, the pressure gradient tightens on the southern end,
bringing gusty northeast winds on Sunday (and to a lesser extent
on Monday), mainly along the south coast into CAPE cod where
winds could gust to 25-35 mph.

Comfortable conditions both days under a deep cold pool. H85 temps
down around 6-8c will support below average high temperatures in the
70s each day... 60s along the east coast on Sunday given increased
onshore flow. Dewpoints remain comfortable in the 50s.

Monday through Thursday...

Monday looks to remain mostly dry with continued influence of high
pressure and only a slowly moistening atmospheric column. Winds
along the south coast remain gusty but start coming down. It's not
until Monday night Tuesday that we really see signs of a warm
frontal feature ahead of two incoming low pressure systems... One
moving from the great lakes into canada, and another potentially
approaching southern new england up the east coast. High degree of
uncertainty on how these features play out and interact with each
other, but the general idea will be increasing moisture as dewpoints
surge back into the upper 60s Tuesday, into the 70s by Wednesday
into late week. Overall an unsettled pattern with at least periodic
rain chances Tuesday through Thursday as several frontal boundaries
and shortwaves move through. Not much instability for thunder, at
least through mid week given cool northeast flow. Temperatures
remain a bit below normal Tuesday, in the 70s, before rebounding
into the low 80s by mid-late week as warmer subtropical air is
pulled up the coast downstream of the trough.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
