Synopsis for massachusetts and rhode island coastal waters.. A cold front south of new england moves farther offshore today. Canadian high pressure moves to the maritimes by late Saturday and lingers there into the first part of next week. A tropical depression is likely to form by early next week off the coast of florida. The system may track close enough to the effect the coastal waters by the mid to late next week with elevated seas. 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
Large high pressure over the great lakes will continue to
transport drier and less humid air into new england and
eventually a fall-like airmass this weekend. Expect mild
afternoons and cool nights with dry weather Saturday followed by
possibly a few showers Sunday especially eastern ma into ri, but
a washout is not expected. High pressure settles over the
canadian maritimes early next week supporting dry cool weather
here along with breezy conditions across CAPE cod and the
islands. Meanwhile we'll be watching a potential tropical system
tracking from the bahamas to well south of new england early to
middle of next week.

Near term until 8 pm this evening
215 pm update...

1026 mb high over the great lakes continues to advect a dry
airmass (dew pt down to 49 at psf) across the region. Southwest
flow continues advect some warm advection cloudiness over
southern new england, so some sunshine thru mid high clouds.

Otherwise not too shabby weather by late aug standards with
temps in the 70s to around 80 and dew pts in the 50s.

Short term 8 pm this evening 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
Highlights...

* expect much cooler than normal temperatures Sunday and Monday
especially along the east coast
* onshore winds will bring spotty light rain or showers at
times into mid week
* temperatures return to near normal levels around mid week
* another chance for showers Wednesday into Thursday
details...

Saturday night through Monday...

with a large high pressure area extending across quebec and
northern new england, a return northeasterly wind flow will
bring cool temperatures across the region especially along east
coastal areas into early next week.

With the onshore wind flow, the long ocean fetch will bring
increasing low level moisture westward. So, can not rule out
periods of spotty light rain and or showers at times mainly over
the weekend. By Monday, it appears the southern extend of the
large ridge will start to shift into N mass, which will bring
drier conditions across the entire region with good subsidence.

So, any spotty precip early should end, though clouds may linger
across eastern and S coastal areas through the day.

Expect daytime highs mainly in the lower to mid 70s, but may
not break 70 along the immediate E coast as well as outer cape
cod and nantucket.

With the long fetch across the western atlc, will see E to ne
winds gusting up to 25-30 mph along the E coast both Sunday and
Monday.

Monday night through Thursday...

the large high center across the maritimes will begin to shift
e during this timeframe as a cold front slowly shifts out of the
great lakes. Winds will diminish somewhat as the pressure
gradient relaxes, then will veer to se-s by later Wed into thu.

Increasing uncertainty as to how quickly the ridge will shift
further offshore along with the timing of the approaching cold
front. At this point, the ridge will keep dry conditions in
place on Tuesday, except for spotty light showers mainly near
the S coast. Deepening layer moisture as well as slowly but
steadily increasing dewpoints will approach starting later
Tuesday and continue through Thursday. Expect highs on Wed to be
close to seasonal levels, then upward to around 5 degrees above
normal on thu.

The approaching cold front will bring a more organized shot for
showers starting late Tuesday night across the E slopes of the
berkshires, then slowly shifting E Wed and thu. Timing of the
actual front still in question due to the exit of the maritime
high pressure.

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.
