Synopsis
Damp weather continues Tue and Tue night as low pressure tracks
over or near the region. Although Tue should be milder than
Monday. High pressure brings dry but chilly weather Wed and thu.

More unsettled weather is expected late Fri into sat. High
pressure builds in Sunday into early next week.

Near term /through Tuesday/
00z update...

much of forecast looks on track. The nearly stationary front at
23z extended along the south coastal new england shoreline,
northeastward through the CAPE cod canal. Weak surface low
circulation was along the front and near the CAPE cod canal,
moving ne. Radar at 23z showed the back edge of scattered
showers at the CAPE cod canal, and should push east of cape
cod/islands by 02z.

One unknown continues to be the extent of dense fog overnight.

Will continue to monitor conditions, but with calm winds and
plenty of moisture, areas of fog are likely.

Lows above freezing all locations in the mid to upper 30s.

Short term /Tuesday night through 6 pm Tuesday/
Tuesday... Over-running with light rain or drizzle. Temps near
50 for highs. Warm front south of long island with plenty of
mixture keeps it cloudy and damp. Pops of likely to
categorical, but the key here is for light rain which I was able
to get into the grids.

Not a lot of sunshine anticipated, despite southern new england
getting into the warm sector of a low pressure in southeast
canada. MAX temperatures should be above normal, in the upper
40s and 50s. Could be warmer if clouds and rainfall are delayed
until late in the day. Low risk of a isolated thunderstorm or
two toward the south coast due to elevated instability.

Long term /Tuesday night through Monday/
No significant changes at this time.

Highlights...

* showers linger Tuesday night as cold front passes through
* cooler but dry weather for Wed and thurs
* unsettled weather returns Friday into Saturday
pattern overview...

12z model consensus continues to show an active weather pattern
for the period. Split flow aloft will continue through the
period with a few shortwaves moving through the flow. Partial
phasing of the two streams will occur across the great lakes and
northeast on Tuesday. This will result in the development of a
low pressure system east of the region late Tuesday into
Wednesday. High pressure and upper level ridge will follow
Thursday into early Friday. The next upper level low/trough
deamplifies as it moves into the mid/upper ridge axis across the
eastern u.S. A coastal low is forecast to develop and quickly
move east in the aforementioned region of this phasing. The
spread has decreased for this timeframe but the still question
in strengthen and location of this system will determine p-types
and QPF amounts.

Details...

Tuesday night... High confidence.

Weak shortwave will move over the region on Tuesday with surface
low pressure over northern new england. Along the cold front,
guidance develops a secondary low pressure system just south of
southern new england by Tuesday night. This wave of low pressure
will bring showery weather Tuesday evening into the overnight
hours. Cannot rule out some isolated thunder with this system as
tt increase above 50 and li's drop below 0. This is strongest
in the conservative ec.

Precip chance will quickly come to an end from west to east
during the overnight hours as CAA takes a hold of the region.

Wednesday into Friday... High confidence.

Trough overhead as upper level low deepens as it moves towards
the canadian maritimes. This puts the region in northwest flow
through the period resulting in dry but breezy conditions.

Clouds may be stubborn on Wed over the CAPE and islands given
northerly flow across the waters. In fact could have some ocean
effect rain/snow showers over the outer cape! Despite cold
advection, the environment should be well mixed, so max
temperatures will be close to normal.

Northwest flow continues on Thursday with an area of high
pressure building in new england. Anticipate increasing
sunshine and lighter winds. Dry and seasonable conditions should
persist through Friday with high pressure in control.

Friday night into the weekend... Low confidence.

Split flow remains over the region with the next southern stream
wave interacting with the northern stream. Still some model
spread in this system leading to a low confidence forecast. The
ec has become more progressive with this approaching coastal low
developing it over 1-95 while the GFS keeps the system
suppressed. The UKMET is more in between the two systems, but
the GEFS and eps continue to show the system south of sne.

Overall a chilly rain with potential for wet snow/sleet at times
on the northern portion of the precip shield. All guidance
suggest system should be or moving offshore by Sunday, thus
drying trend possible second half of the weekend.

Aviation /00z Tuesday through Saturday/
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term /through Tuesday/... High confidence.

overnight. Light winds.

Tuesday... Ifr conditions likely in areas of rain and fog. Chance
for lifr.

Kbos taf... Moderate confidence. Ifr to lifr through much of the

Kbdl taf... Moderate confidence. Ifr to lifr through much of the
period.

Outlook /Tuesday night through Saturday/...

Wednesday into Thursday... High confidence. Gusty n/w winds
Wednesday withVFR conditions into Thursday.

Friday... Moderate confidence. VFR and dry to start but likely
lowering to MVFR or possibly ifr Fri night in rain/wintry precip.

Saturday... Moderate confidence. MVFR or possibly lower in rain/wintry mix.

Marine
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term /through Tuesday/... Moderate confidence.

Rough seas across the eastern outer coastal waters are more
likely than the southern outer waters. Continued the small craft
advisories for those waters. A few gusts to 25 kt are also
possible this evening.

Tonight... A weak frontal boundary sweeps the waters, with light
west winds developing. This will allow seas to subside and small
craft advisories to conclude.

Tuesday... Light south winds with frontal boundary north of the
region. Vsby reduced at times in rain and fog.

Outlook /Tuesday night through Saturday/...

Tuesday night... Moderate confidence. Winds becoming northeast late
tue night as front slips south and wave of low pres tracks along the
front south of new england. Vsby reduced at times in rain and fog.

Wednesday into Thursday... High confidence. Gusty north winds near
Wednesday into early Thu then diminishing as high pressure builds
into the area later thu.

Friday... High confidence. Quiet weather with high pressure over the
area early fri. However increasing east-southeast winds Fri night as
low pres approaches from the west. Also vsby lowering in rain and
fog Fri night.
