Synopsis for massachusetts and rhode island coastal waters.. High pressure moving over the maritimes will bring northeast winds to the southern new england coast starting today. The winds may be joined by a few light showers, especially across the waters south of boston. Northeast winds will be gradually shifting to the east by midweek. A tropical depression may form off the coast of florida early next week. This system may track close enough to affect the coastal waters with 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 bring low clouds and light
showers to southeast new england through at least midday. High
pressure lingers over new brunswick through midweek, bringing
fair dry seasonable weather to most of southern new england. A
cold front then crosses from the west, bringing showers and
scattered thunderstorms late Wednesday and Thursday. Still have
an eye on the tropics at this time, with potential high surf
and dangerous rip currents for the atlantic-exposed shoreline
of southern new england.

Near term until 6 pm this evening
Surface high pressure moves over the maritime provinces of
canada. Its position will direct east-northeast winds across the
gulf of maine into southern new england. These winds will pick
up moisture from the gulf of maine and bring it onshore over
eastern massachusetts and rhode island. The result will be areas
of clouds and light showers drizzle that move over this area
during the morning, possibly lingering later near the south
coast. Clouds will clear over northeast ma, and break over much
of southeast ma and ri.

The maritime high will provide plenty of subsidence over
southern new england. Cross sections even over eastern ma show
dry air at and above 700 mb through the day. This suggests
interior sections, especially the ct rvr valley, should have a
dry day with partly to mostly sunny skies. The mixed layer
reaches to about 850 mb where temperatures are forecast at 8-9c.

This would support MAX sfc temps in the low to mid 70s, with
areas along the eastern coast struggling to break 70.

East-northeast winds will gust 20 to 25 mph over land in east
coastal areas, then diminish toward evening.

Short term 6 pm this evening through 6 pm Monday
Tonight...

clouds diminish a little, but remain in place over southern ri
and southeast ma. Cross sections show moisture lingering below
900 mb until Monday morning. Clearing skies farther inland due
to the subsidence from the maritime high.

Dew points remain low dry, ranging from the mid 40s in NW mass
to the 50s across much of southern new england. With light wind
from the high pressure, expect temperatures to the 40s over
western ma and the 50s to around 60 over the remainder of the
region.

Ene wind gusts 25 to 30 mph along the south coast, while winds
are light across northern and western mass.

Monday...

high pressure expands a little and brings drying clearing to the
south coast. Expect a dry weather day. Temperatures aloft at the
top of the mixed layer will be 8-10c, so daytime temperatures
should be in the 70s.

Long term Monday night through Saturday
Highlights...

* temperatures will remain cool into Tuesday, then will moderate
to near and above normal by late this week
* onshore winds will bring spotty light rain or showers at times
into mid week, best chances on Wednesday
* scattered showers will move across late Wednesday through
Thursday
details...

Monday night and Tuesday...

high pressure will remain across the region, with the center
anchored across eastern canada into northern maine. This will
keep a cool e-ne wind flow in place. 00z models indicating that
the high center may actually slip S across the region by
Tuesday, so the e-ne winds, which may gust up to 15-20 mph early
Monday night will diminish. This will allow good subsidence and
dry conditions during this timeframe. May still see onshore
winds along the immediate coast on Tuesday.

Temperatures will moderate to near normal levels on Tuesday with
the lighter winds. Expect highs mainly in the 70s, but may hang
near 70 along the immediate E coast.

Wednesday through Friday...

big question at this point will be the passing of the potential
tropical system around the mid to late week period. 00z models
starting to show more spread as the low shifts NE from off the
carolina coast, which lends to lower confidence. In the
meantime, a cold front tries to shift E out of the eastern great
lakes to western ny pa.

The western edge of the high will ever so slowly shift E wed,
but the circulation around the offshore system will keep winds
from the E or se. May also see some showers develop off the
ocean across E mass into ri during the day.

At this point, showers develop across western areas as the
front approaches Wed night through Thu as the front passes.

This could be slower, however, depending upon the timing and
track of the passing offshore system.

The early morning forecast still suggest that the tropical
system will pass well southeast of nantucket. The most likely
impact from this system may 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.

Aviation 08z Sunday through Thursday
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Monday ... Moderate confidence.

Today...

vfr most areas, although with patchy clouds. An area of
2000-2500 foot ceilings moves in from the east across eastern
ma and ri, with low clouds light showers drizzle. These low
conditions improve toVFR during the afternoon. East-northeast
winds become gusty across CAPE cod and islands, possibly the
south shore of eastern ma, then diminish toward evening.

Tonight...

high pressure over the maritimes will bring partial clearing to
the south coast, and mostly clear skies across the remainder of
southern new england. Light wind and temps near saturation will
allow patches of fog to form, causing a period of ifr CIGS vsbys
during the late night. East-northeast wind 10 to 15 kts.

Monday...

vfr with clearing skies along the south coast. East-northeast
wind gusting 20 to 25 kt along the coast.

Kbos terminal...

moderate confidence in low ceilings this morning.

Marine
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Monday ... High confidence.

Long-fetch E NE winds will produce wind gusts 20 to 30 kt and
seas building to around 5-6 feet. High pressure centered over
the maritimes will maintain the ene wind through Monday,
maintaining the rough seas on the outer waters through that
time.

Wind gusts of 20 to 25 kt are likely on the southern waters
with 25 to 30 kt possible on the southern outer waters. Wind
gusts diminish Monday as the maritime high pressure expands
south.

The small craft advisory continues in effect. We extended the
advisory period through the day Monday. No other significant
changes were made.

Outlook Monday night through Thursday ... Moderate confidence.

Monday night: winds less than 25 kt. Seas up to 5 ft.

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

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

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

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