Synopsis
High pressure will maintain dry weather and warmer than normal
temperatures through the weekend. Precipitation chances will
increase by the middle of next week.

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

as forecast well by the narre, areas of low cloudiness and fog
were forming across southern new england... Mainly south of the
mass pike. We have issued a special weather statement for the
fog in eastern ct, ri, and southeast ma valid through about 8
am. Some of the fog was locally dense, especially from plymouth
to new bedford and on upper CAPE cod from falmouth to hyannis.

The fog should lift a few hours after sunrise. Temperatures were
off to a chilly start, with upper 30s to mid 40s across much of
the region.

After areas of fog lift, skies will become sunny today. A weak
upper level short wave trough will move across new england late
this afternoon and early this evening, accompanied by some
high level cirrus clouds. At the surface, a weak, dry cold
front associated with this trough will be approaching the region
during the day. South-southwest winds ahead of this front will
become gusty this afternoon, reaching 35 kts at 925 mb, which
could translate to a few gusts to 25-30 mph possible at the
surface, especially in the late afternoon. Have continued on
the higher side of guidance for maximum temperatures this
afternoon... Mainly in the lower 70s but cannot rule out a few
mid-70s readings in the ct valley and in eastern ma. Cooler over
cape cod and the islands.

Short term 6 pm this evening through 6 pm Friday
Tonight... Weak front shifts to the east. Clear skies. Winds
shift to the W and weaken overnight. Lows mainly in the 40s
except some 50s CAPE and islands.

Friday... Strong high pressure centered over the appalachians
will provide bright sunshine. Northwest winds may gust to near
20 mph during the afternoon. High temperatures are only
expected to be slightly cooler... In the upper 60s to around 70.

Long term Friday night through Wednesday
* above average temperatures with dry conditions lasting into Monday
* precipitation chances are increasing for the middle of next week.

19 00z guidance remains in excellent agreement through this weekend.

High pressure in control with dry weather and above normal
temperatures continuing.

Some detail difference begin to arise with the handling of a closed
mid level low across the southern tier of the usa early next week.

These detail differences are almost entirely the result of timing
differences in breaking down the strong mid level ridge along the
eastern seaboard. The primary impact of this closed low will be to
provide energy ahead of a cold front toward the middle of next week.

Given the strength of the downstream ridge, will favor the less
progressive guidance, which would be closer to the 00z ecmwf.

That said, it is becoming increasingly likely our region will see
some light precipitation sometime late Monday night into Wednesday,
with the most likely timeframe currently being around Tuesday. This
could change over the next several days as the timing of a slow-
moving front becomes clearer.

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

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Friday ... Generally high confidence.

330 am update...

areas of ifr conditions -- ceilings and visibilities -- in low
clouds and fog, mainly south of the mass pike early this
morning. The fog will be locally dense, especially along the
south coast from new bedford to plymouth and on upper CAPE cod
from falmouth to hyannis. Expecting any areas of fog to
dissipate by mid-morning, withVFR and clear skies taking hold.

Just a few cirrus clouds as a front approaches from the west
late in the afternoon.

Sw winds may gust to 23-27 kt this afternoon, especially toward
21z.

Vfr conditions tonight and Friday. Winds shifting to the w
tonight and diminishing, then NW Friday with gusts up to 20 kt.

Kbos terminal... High confidence in taf.

Kbdl terminal... Moderate confidence in TAF this morning, then
high confidence through Friday.VFR conditions. However, there
is a low risk for localized ifr ceilings developing around
daybreak, especially to the east of the airport.

Outlook Friday night through Monday ...

high confidence.VFR.

Marine
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Friday ... High confidence.

Today and tonight... S-sw winds increase this afternoon with
gusts to around 25 kt likely over all waters by late afternoon
and a slight increase in outer seas to near 5 ft. These winds
persist into the overnight but slowly diminish as they shift to
the W late tonight. Small craft advisories are in effect for
all waters.

Friday... Nw winds may gust to 20 kt and seas are forecast to
slowly subisde to 3 to 4 ft.

Outlook Friday night through Monday ... High confidence.

Great boating weather as high pressure prevails through this
upcoming weekend with sub small craft advisory conditions.

Fire weather
Ahead of a very weak cold front, s-sw winds will gust 20-25 mph
across much of the region this afternoon. There is a chance of
a few gusts to 25-30 mph by 4 or 5 pm. Relatively mild
conditions (highs in the low-mid 70s) and continued dry
dewpoints in the mid 40s to low 50s will yield min rh values
between 30 and 35 percent. With an overall recent lack of
precipitation, there could be an elevated fire weather risk for
today. A special weather statement has been issued highlighting
this risk.

On Friday, NW winds will be a little less, closer to 20 mph, but
the minimum rh will be closer to 30 percent. Thus there could
again be some risk of elevated fire potential.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
