Synopsis
Dry and seasonably cold conditions today and Friday, then a
warming trend this weekend with continued dry weather. A storm
system will affect the region sometime Monday night into Tuesday
with mostly rain and coastal wind, but there is a risk of some
mix ice across the interior. Blustery and colder weather follows
next Wednesday.

Near term through tonight
630 am update...

still some lingering low clouds across the CAPE islands which
may persist for a few hours per low level rh fields. Meanwhile,
area of high clouds streaming north along the south coast,
ahead of coastal low to the south. These clouds should move
offshore by midday, otherwise lots of sunshine today across
sne.

Expect temps to only reach the lower-mid 20s across the e
slopes of the berkshires, ranging to the lower-mid 30s across
the coastal plain.

Short term Friday
Tonight and Friday...

as the h5 cutoff low finally pushes offshore tonight, NW winds
will diminish as the surface ridges builds E across the region.

Skies will remain mainly clear early.

Noting another h5 short wave in the fast flow out of the great
lakes, which will cross the region around or after midnight.

Little if any moisture with this system, and what there is should
pass across northern new england overnight. Will see mid level
clouds move across, then start to lift NE toward daybreak. May
see some brief lower clouds across portions of NW mass during
the pre dawn hours. Expect lows mainly in the teens, ranging to
the lower-mid 20s along the coast.

The short wave will quickly push to the maritimes Friday
morning, taking the clouds with it though some scattered high
clouds may linger across central and N mass during the day.

Winds will be mainly w, so expect temps to run close to seasonal
normals, topping off in the upper 20s to lower 30s across
central and western areas, ranging to the mid 30s along the
coast.

Long term Friday night through Wednesday
Highlights...

* dry and mild this weekend
* another storm will bring mostly rain and gusty coastal winds
mon night Tue with a risk of some interior mixed precip ice
mild and dry conditions expected this weekend under zonal flow
and rising heights. Temps should reach well into the 40s both
days with the chance of a few 50 degree readings sat. It will
be a bit breezy Sat with potential for 25-35 mph SW gusts near
the coast which will temper the milder temps but less wind
Sunday.

Some light precip in the form of rain snow showers possible mon
in the developing warm advection pattern, but models have
trended a bit slower with timing of next storm, with greatest
impact likely sometime late Mon night into tue. Deep mid level
trough low approaching from the west is expected to lift ne
across the gt lakes and into SE canada. A robust pre-frontal low
level jet will likely bring a decent slug of rain to sne with
potential for heavy rainfall and strong coastal wind. Pwat and
low level wind anomalies are 2+ sd which is pretty good for a
day 5-6 forecast. Exact timing of the rain and wind is uncertain
and there also remains enough uncertainty with thermal profile
that some interior mix ice possible at the onset. ECMWF is more
robust with the colder air but it will take awhile for these
finer details to be resolved.

As storm exits, blustery and colder weather will likely follow
next Wednesday.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
