Synopsis
Dry, windy and cold conditions prevail through tonight. Milder
temperatures arrive Sunday, but it will turn colder again Monday
into the middle of next week.

Near term through tonight
Satellite imagery shows the trough well to our east, with mostly
clear skies prevailing. This continues overnight with dry
conditions and lows in the upper 20s. The main thing tonight
will be the winds. Given a tight pressure gradient on the back
side of the low and a 30-35kt LLJ at 925mb we continue to see
west winds gusting to 30-35 mph in spots. Winds will remain
elevated through the evening and into the overnight hours,
coming down steadily as the pressure gradient relaxes. Dry
overnight with lows dipping into the upper 20s.

Short term Sunday through Sunday night
Sunday and Sunday night...

under a weak shortwave ridge we'll see a very nice Sunday. Dry,
with plenty of Sun to start. Some high level then mid level
moisture begins to move in by afternoon so we'll see increasing
clouds from west to east during the latter half of the day. A
good warmup in store as temperatures will be 10-15 degrees
warmer than today, in the mid to upper 50s. This puts us about
10 degrees warmer than average for late march. Temperatures
along the south coast will be cooler, in the low 50s as west
winds become southwest and advect in a cooler marine influence.

Sunday night our next weak, moisture starved shortwave moves
through bringing a cold front in the early hours of Monday
morning. We still stand a chance of seeing some showers out of
this, but have trended pops down. Latest runs of the NAM and ec
have trended progressively drier with not enough moisture to
even get widespread light showers. For now keeping a slight
chance of mainly rain showers given the mild airmass (lows in
the low 40s overnight)... Could see some snow in the highest
terrain of western ma. If we see anything not expecting much in
the way of qpf.

Long term Monday through Friday
* dry through the week with high pressure building over the region
* colder weather follows through mid week, then temperatures look to
rebound late next week
details...

Monday...

light precip associated with the frontal passage may linger into the
late morning hours but will dissipate soon there after as dry air
pushes into the region. Monday will be cooler following the frontal
passage, but CAA looks slow to enter the region so temperatures will
likely be near normal in the mid 40s. Radiational cooling will be a
factor Monday night with clear skies and light NW winds. Models show
850 mb temps overnight dropping to near -15c, allowing
temperatures at the surface to cool into the teens and 20s.

Tuesday through Friday...

models show dry conditions through the week as a high pressure
begins to build over the region Tuesday, keeping skies clear but
temperatures below normal through Wednesday. Radiational
cooling will continue to be a factor through Wednesday evening,
keeping overnight lows well below normal.

As the high pressure shifts offshore Wednesday night, winds will
shift to the s-sw, returning temperatures above normal through the
end of the week.

Saturday...

as the high pressure departs new england Saturday, a low pressure
system approaches from over the great lakes bringing the next chance
for precipitation. Global models are not yet in agreement on timing,
but precipitation type will likely be rain given both the gfs
and ECMWF are signaling that 850 mb temperatures will not drop
below freezing after the frontal passage.

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.
