ANZ200 716 Am Edt Sun Aug 25 2019
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. Expect
dry and seasonable conditions to continue through mid week as
high pressure shifts slowly offshore. A cold front may bring
showers into central and western areas Wednesday night and
Thursday. However, this will be dependent upon the track of a
potential tropical system that may pass well southeast of
nantucket around mid to late week, which could produce high
surf and dangerous rip currents along the immediate shoreline.

Near term until 6 pm this evening
720 am update...

bands of showers have been moving westward across CAPE cod and
the islands, as well as been developing along the E coast of
mass and have been pushing inland since around sunrise as seen
on NE regional 88d radar imagery. Noting a few of this showers
have brief downpours, but have been moving steadily W before
dissipating not too far inland.

As suggested by the previous forecaster, a lot of dry air aloft
which should mix down and keep skies partly to mostly sunny
across central and northern areas. Across E coastal mass and
ri, should see the showers dissipate as they shift west. May see
a few more spotty showers through late this morning, then
should end as drier air starts to filter s.

Have updated near term to bring conditions current.

Previous discussion...

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, which will pick up
moisture and bring it onshore over eastern massachusetts and
rhode island. The result will be areas of clouds and light
showers 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 during
the afternoon.

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
8c-9c. This would support MAX sfc temps in the low to mid 70s,
with areas along the east coast will struggle 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.

E-ne 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 12z 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
2000-3000 foot ceilings moves in from the east across eastern
ma and ri, with low clouds and light showers. These low
conditions improve toVFR around midday, possibly during the
afternoon along the S coast. 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
visibility 1 to 3 nm.

Thursday: winds less than 25 kt. Areas of seas approaching
