Synopsis for massachusetts and rhode island coastal waters.. A cold front south of new england moves farther offshore today. Showers along the front will also move farther offshore. Canadian high pressure moves to the maritimes by late Saturday and lingers there into the first part of next week. This brings fair weather and less humidity for much of the forecast period. Winds become northeast Saturday afternoon and increase in speed Sunday and Monday. 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
A wave of low pressure tracking along a cold front south of the
islands will bring a period of light rain to the south coast of
massachusetts and rhode island the remainder of the morning.

Then clouds will thin and give way to some breaks of afternoon
sunshine as this wave of low pressure moves offshore. A fall-
like airmass will then invade southern new england tonight into
the weekend as large high pressure moves from the great lakes
today into the maritimes by Sunday. Mild afternoons and cool
nights will be featured. Dry weather Saturday with possibly a
few showers Sunday especially eastern ma into ri, but a washout
is not expected. Cool maritime high pressure remains in control
early next week 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.

Near term until 8 pm this evening
10 am update...

back edge of rain shield now confined to the south coast of
ma ri and continuing to move southward as post frontal airmass
surges southward. Thus trend toward drier and less humid weather
this afternoon. Back edge of cloud shield over northwest ct into
central ma along with cloud shield thinning. So continue to
expect clouds thinning and giving way to afternoon sunshine from
northwest to southeast this afternoon. Previous forecast
captures this trend well so no major changes with this update.

Previous discussion...

once the flow shifts, expect clearing skies, earliest 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 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.
