Synopsis for massachusetts and rhode island coastal waters.. High pressure over the maritimes will build south over the waters early this week. This will bring slowly diminishing wind and seas during that time. A tropical depression may form off the coast of florida early this week. If the tropical system tracks close enough to our waters it could bring elevated seas by mid week. A cold front will approach the waters from the west on Thursday. 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
High pressure over the maritimes will build over southern new
england today and maintain dry pleasant weather through Tuesday.

Possible showers Wednesday and Thursday ahead of a cold front.

Still keeping an eye on the track of a potential tropical system
offshore late this week, which could produce high surf and
dangerous rip currents along the immediate shoreline.

Near term until 6 pm this evening
High pressure centered over the maritimes is building south
across new england. This is diminishing the wind over southern
new england and decreasing the onshore flow of moist air and
resulting clouds. It is also increasing the subsidence and
resulting drying of the air.

Most of the low clouds that lingered over ri and SE mass had
dissipated by 230 am. Another area of clouds was becoming
uncovered over georges bank... This was trending west and the
current trend would bring it to the outer CAPE and nantucket
around 930 am. That assumes it doesn't dissipate from subsidence
along the way.

Aside from the question of clouds over the CAPE this morning,
the overall trend for southern new england is subsidence sunny
skies dry air courtesy of the northern high pressure. Gusty
east-northeast winds will be strongest on the islands, weakest
in northern massachusetts. Gusts on the CAPE and islands may
reach 20-25 mph.

Solar mixing is expected to reach near 850-mb, where
temperatures will be 8-10c. That suggests MAX sfc temperatures
today will be in the 70s. Along the eastern mass coastline, a
few spots may top out in the upper 60s.

Short term 6 pm this evening through 6 pm Tuesday
High pressure remains in control tonight and Tuesday. Light
winds will allow temperatures to radiate tonight. Dew points
will be 45 to 55, so min temps should range from the mid 40s
inland through the 50s. The radiational cooling may also bring
areas of fog. Favored areas include the ct river valley of mass,
and the normal fog-developing spots region-wide.

Subsidence should maintain clear or mostly clear skies during
the day Tuesday. Deeper subsidence may limit the mixed layer to
just 925-mb. Temps at 925 mb will be about 16c, equiv to 8-9c
at 850 mb. That would support MAX sfc temps in the 70s.

Long term Tuesday night through Sunday
Highlights...

* temperatures will remain below normal Tuesday, then will
moderate to near and above normal by late this week
* scattered showers will move across our region sometime late
Wednesday into Thursday ahead of a cold front.

Details...

Wednesday through Friday...

the biggest question remaining to be answered will be how close
a potential tropical system comes to southern new england during
this time. Latest model guidance has trended ever so slightly
west, but still well within the margin of error for a forecast
this far out. Still expecting a cold front to slowly approach
from the west late Wednesday into Thursday. At this point,
expecting scattered showers with the cold front. Instability is
too poor to warrant a mention of thunderstorms in the forecast.

Rainfall chances would be significantly higher if the ocean low
pressure comes even closer to our region. Time will tell. The
most likely impact from this coastal system would be a period
of rough surf along ocean-exposed beaches.

There may be another front that might approach late this week,
but timing is very much in question.

Near to above normal temperatures should prevail during this
period.

Saturday and Sunday...

high pressure should be in control. Current forecast is for dry
weather. Above normal temperatures Saturday, with below normal
temperatures Sunday as this high pressure moves in.

Aviation 07z Monday through Friday
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Tuesday ... High confidence.

Today...

high pressure over new brunswick will maintain mostly clear
skies across the region and east-northeast winds today with
strongest winds gusting 20 to 25 kt across the south coast and
islands. The high will build south over our area late today,
diminishing the wind.

There is some concern about an area of clouds over the ocean
near georges bank, moving west. If these clouds hold together
they should reach outer CAPE cod and nantucket about 930 am and
affect the CAPE and islands with 2500 foot ceilings through the
rest of the morning. This will need to be monitored.

Tonight...

high pressure over the region will bring clear skies and light
wind. Radiational cooling will bring areas of fog, especially
over the ct river valley in mass. And in the regular fog spots
of SRN new england. Ifr CIGS vsbys in any fog.

Tuesday...

high pressure continues to bring mostly clear skies and light
wind. Thin cirrus will move in from the west, most likely over
ct and western ma.

Kbos terminal... High confidence in taf.VFR clear with ene wind
around 10 kt.

Kbdl terminal... High confidence in taf.VFR clear with a light
ene wind.

Marine
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Tuesday ... High confidence.

High pressure over the maritimes is building south over the
waters. But it continues to generate east-northeast winds over
the southern new england waters with strongest winds south of
the islands with gusts to 25 kt. The persistant wind has built
seas to 5-7 feet
as the high builds farther south today, the winds will diminish
with light winds on all waters tonight and Tuesday. Seas will
linger at 5-7 feet today and tonight, then diminish during the
day Tuesday. We will maintain small craft advisories through
that time.

Outlook Tuesday night through Friday ... Moderate confidence.

Tuesday night: winds less than 25 kt. Areas of seas approaching
5 ft.

Wednesday: winds less than 25 kt. Areas of seas approaching
5 ft. Chance of rain showers.

Wednesday night: winds less than 25 kt. Areas of seas
approaching 5 ft. Chance of rain showers. Local visibility 1 to
3 nm.

Thursday: winds less than 25 kt. Areas of seas approaching
5 ft. Chance of rain showers.

Thursday night through Friday: winds less than 25 kt. Seas
locally approaching 5 ft.
