Synopsis
High pressure over the great lakes builds into new england
today, then moves offshore this evening. This will bring a
period of dry and seasonably cool weather to the region. Low
pressure then tracks along the coast Sunday with a wind-swept
rain, except freezing rain ice for the interior Sunday morning.

Strong to damaging winds develop Sunday night, peaking around
Monday, then gradually diminishing into Tuesday. A mostly quiet
week thereafter, watching a potential storm for next weekend.

Near term until 6 pm this evening
10am update...

overall forecast remains on track. Main update this morning will
be to lower temps a bit based on two issues. One is the colder
start this morning, the other is the ci shield which is
gradually becoming more dense with time. Still, seasonable highs
are expected, mainly in the low 40s and upper 30s with filtered
sunshine becoming more fully ovc as the day GOES on.

Timing of precip, etc still looks good at this time, so will not
make any changes to it with this update.

Short term 6 pm this evening through 6 pm Sunday
Looking at another round of wintry mess late tonight into
Sunday. The biggest threat will be from freezing rain, although
there could be some light snow or sleet at times, too. Have
posted a winter weather advisory where we have the greatest
confidence in light icing. Most areas should see up to a tenth
inch of icing, but could see up to two tenths towards NW ma,
where icing should persist longer. It's possible this advisory
could be expanded, should confidence in freezing rain increase
farther south and east.

Eventually warm air will win out, transitioning all
precipitation to simple rain across all of southern new england.

This rain should then persist though most of Sunday morning,
then gradually end from SW to NE during Sunday afternoon.

Winds increase late tonight into Sunday as a secondary low
pressure passes by. Gusty winds should be confined to the
immediate coast, including the CAPE and islands, through Sunday.

With lots of clouds and an increasing SE to SW flow,
temperatures should remain above normal through this period.

Long term Sunday night through Friday
* highlights ...

- strong, damaging winds starting Sun night, peaking mon
- low confidence in wet weather potential mid week & next
weekend
Sunday night through Tuesday...

strong and potentially damaging winds move in starting Sunday
night, peaking during the day Monday, and diminishing through
the day Tuesday. As the low strengthens over southeast canada
it drags a cold front through southern new england late Sunday
as the mid level trough and cold pool moves overhead. Post-
frontal winds turn out of the wnw and begin to increase as the
pressure gradient tightens on the back side of the low. Between
the deepening low and incoming high pressure this gradient
tightens bringing sustained winds up mainly after midnight and
peaking Monday afternoon 25-35 mph. At the same time good caa
aloft will promote very efficient mixing up to 700-800 mb
depending on the guidance. Either way model soundings indicate
potential for damaging wind gusts to mix down from a 55-60 kt
850mb jet. Expecting fairly widespread wind advisory criteria
with gusts of 50-55 mph. Certainly possible we could reach high
wind warning criteria in the berkshires and along the coastline
with gusts approaching 60 mph. A gale watch is in effect over
the waters, but it may well be upgraded to a storm watch soon.

Potential impacts include power outages and downed limbs trees.

After Monday afternoon evening winds decrease through the night
into Tuesday but will still be gusty given continued efficient
mixing; likely we'll see gusts 35-40 mph through Tuesday
afternoon. High temperatures drop ~10 f on Tuesday, into the
upper 20s which, with gusty winds will feel like teens to single
digits.

Wednesday through Friday...

mid level flow remains rather zonal across the CONUS for much of
late week. While models show little agreement in details beyond
Friday, no very big or impactful storms are likely. High
pressure crests on or about Wednesday with dry weather
persisting. Beyond that the GFS brings a weak clipper-like
system through Wednesday night while the ec keeps any wet
systems out of sne through the rest of the week, so trending the
forecast to a drier eps solution. Focus then shifts to late next
weekend and another potential wet system.

Aviation 18z Saturday through Thursday
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Sunday ... High confidence.

Through midnight local...

vfr. Gradually lowering CIGS and precip approaching from the
w-sw, but it should remain out of the area until after midnight
for all but the very far W ma ct terminals. Winds light and
variable, but with a slight bend to the east thanks to sea
breezes until the overall wind takes over.

After midnight into late Sunday...

gradual drop to predominantly ifr with timing off a bit in the
tafs possible. Mid of fzra pl especially interior ma ct through
the early morning hours, with all rain expected especially after
15z. Some light ice accums possible especially at terminals in
higher terrain. Mix of br dz will allow the ifr conditions to
linger into Sun evening. Some llws especially across SE ma.

Sun night...

improvement toVFR as br dz ends during the evening. However
winds will be gradually increasing through the overnight hours
with gusts as high as 30 kt out of the w-nw by sunrise mon.

Kbos terminal... High confidence in TAF if any pl fzra is
observed it would be very short lived, with little to no
accumulation expected.

Kbdl terminal... High confidence in taf.

Outlook Sunday night through Wednesday ...

Sunday night:VFR. Strong winds with gusts up to 45 kt. Slight
chance ra.

Monday:VFR. Strong winds with gusts up to 50 kt.

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.
