Synopsis for massachusetts and rhode island coastal waters.. A cold front stalls south of the waters today. Weak high pressure from canada builds across the waters today bringing a light shifting wind. Disturbances moving along the stalled front will bring periods of showers later tonight through Friday. Widely scattered Thunderstorms are possible on Tuesday.

Synopsis
A cold front that moved through southern new england last night
stalls south of the coast. Weak high pressure builds over the
region, bringing us dry weather today. The stalled front will
linger south of our area for much of the week. A series of
disturbances moving along the front will bring rounds of
showers during the week, along with embedded heavy downpours
and possibly a few thunderstorms. Dry conditions may return next
weekend.

Near term until 6 pm this evening
Early morning satellite imagery shows clearing skies over
northern ny and vt nh. This clearing is trending se, so we
expect clearing skies during the morning in
western central northeast sections, while clouds linger along
the south coast and parts of ri and SE mass until midday.

Cold front has moved through the region, with a light west-
northwest wind observed at most stations. The front is becoming
aligned parallel to the zonal upper flow, so we expect it to
stall south of the islands duirng the day.

High pressure will encourge light wind, but also a shifting
wind. Expect winds turning out of the east and southeast during
late morning and afternoon along the coast.

The developing Sun will encourage some mixing, with the layer
reaching to 850 mb. Temps at that level will be 10-12c, so full
mixing would support MAX sfc temps in the upper 70s and lower
80s. On the other hand clouds associated with the stalled front
may interfere with full mixing. We stayed close to existing
forecasts.

Short term 6 pm this evening through 6 pm Tuesday
The next upper shortwave crosses the region from west to east
tonight and Tuesday, with the best jet support... Right entrance
region... Passing late tonight and Tuesday. Expect increasing
pops during this time, with highest values reached along the
south coast and lower values along the northern mass border.

Absent a low level east flow or any above-surface southerly flow
and overrunning, we are calling this showers. Stability
parameters are mediocre for any thunder signal. But k index does
barely reach 30 along southern parts of ct-ri-se mass, so we
have indicated widely scattered thunder in this area Tuesday.

Dew points around 60 both tonight and Tuesday. This should keep
min temps 60 to 65. Little mixing depth Tuesday, but low level
temps will be equiv to 850 temps of 6-8c. So the forecast sfc
highs will be upper 60s to mid 70s.

Long term Tuesday night through Sunday
Highlights...

* bouts of rain, embedded heavier showers, possible thunderstorms
through Friday
* seasonable temperatures throughout, warming toward the weekend
* drying out Saturday Sunday
details...

Tuesday night and Wednesday...

continued unsettled pattern with quasi-zonal flow which allows a
quick progression of shortwaves through the region. Stalled frontal
boundary continus to linger in the vicinity laying w-e parallel to
steering flow. With this front, a quasi-stationary upper jet in
favorable position for synoptic lift, and precipitable water values
consistently above 1", a series of weak disturbances will bring a
chance of rain and isolated thunderstorms. The main lifting
mechanism is a surface wave of low pressure passing to the south.

Still some uncertainty on the track of this which will impact how
widespread rain chances are Tuesday night and Wednesday. Not a lot
of model consensus at this point so leaning toward a blend giving
chance pops throughout; highest likelyhood south of the ma ct
border. Highs hover just below normal, in the 70s... Cooler along the
coast.

Thursday and Friday...

should see a break in the rain, if briefly, on Thursday between
disturbances. Looking upstream a surface low which formed in the lee
of the rockies a day previous moves into the ohio valley,
strengthening as it moves toward new england late Thursday. This
being the strongest and most organized system of the week, we also
see a more amplified mid level trough axis approaching, ahead of
which moisture advection brings a plume of pwats ~2". It means
widespread potentially heavy rainfall and scattered thunderstorms
for southern new england sometime around late Thursday Friday.

Timing details are still uncertain and will depend on exactly how
wed-thurs plays out but by Friday night most of the rain should have
moved out.

Saturday and Sunday...

by next weekend we finally see a pattern change as flow becomes more
meridional in a western trough eastern ridge set up. Rising heights
and building surface high pressure should keep things dry and sunny.

Increasing subsidence will also help temperatures warm a bit, though
no major heat waves are expected for the 7 day forecast period.

Aviation 08z 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 ...

today... Moderate confidence on timing of lifting ceilings. High
confidence the remainder of the day.

Lingering ifr-lifr ceilings in eastern mass ri and parts of ct
this morning.VFR farther north west. Expect clearing skies and
conditions lifting toVFR. There is a chance that low ceilings
may linger at nantucket much of the day. Sea breezes will
develop, especially along the east mass coast, from late morning
through the afternoon.

Tonight... Moderate confidence.

Vfr to start, then conditions lower to MVFR ifr overnight. The
south coast will be most favorable for this, while the
transition may take longer farther north. Initially it will be
due to lowering ceilings. Later in the night, showers will move
into the region bringing lower visibility. Best chance for
showers will be along the south coast.

Tuesday... Moderate confidence.

Ifr ceilings ct-ri-se mass, MVFR ceilings to the north. Vsbys
3-5 nm in showers in the south, 5 to 10 nm in the north. Fog
along the southern areas may bring vsbys to 1-2 nm at times.

There is a slight chance of thunder in southern areas, mainly
along the south coast.

Kbos terminal... Moderate confidence in taf.

Kbdl terminal... Moderate confidence in taf.

Outlook Tuesday night through Friday ... Moderate confidence.

Tuesday night: MVFR ifr conditions possible. Chance shra,
patchy br.

Wednesday: MVFR ifr conditions possible. Chance shra, isolated
tsra.

Wednesday night: mainly MVFR, with areas ifr possible. Chance
shra, isolated tsra, patchy br.

Thursday: mainly MVFR, with local ifr possible. Shra likely.

Thursday night: mainly ifr, with areas MVFR possible. Shra
likely, slight chance tsra, patchy br.

Friday: mainlyVFR, with local ifr possible. Chance shra,
isolated tsra.

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.

Today...

high pressure in canada will bring light shifting winds today.

Northern waters will show clearing skies, while waters south of
new england will have variable sky cover. Winds will remain
below 20 knots. Lingering 5 foot seas in the southern outer
waters will diminish this morning. Small craft advisory
continues on the southern outer waters this morning.

Tonight...

another weather disturbance approaches from the west tonight.

Expect clouds to fill in again, and showers will develop later
in the night. Showers and fog will lower visibility overnight.

Winds and seas should remain below small craft criteria.

Tuesday...

the weather disturbance moves past southern new england,
bringing reduced visibility in showers and fog to the waters.

There is also just enough instability indicated to support
widely scattered thunderstorms over the waters south of southern
new england. Outside of any thunderstorms, winds should remain
below 20 kt and seas below 5 feet through the day.

Outlook Tuesday night through Friday ... Moderate confidence.

Tuesday night: winds less than 25 kt. Chance of rain showers,
isolated thunderstorms, patchy fog. Local visibility 1 to 3 nm.

Wednesday: winds less than 25 kt. Seas locally approaching
5 ft. Chance of rain showers, isolated thunderstorms.

Wednesday night: winds less than 25 kt. Seas locally
