316 am edt Tue mar 19 2019

Synopsis
Cool high pressure builds across the northeast today and
tonight. As it moves offshore tomorrow a southwest wind will
bring warmer air back into the area for Wednesday and Thursday.

A cold front approaches from the west Thursday into Friday, but
it will stall as it arrives into northern new england. Low
pressure developing over the carolinas will track north along
this front and bring precipitation to new england mainly on
Friday. Whether this comes as wintry precipitation or as rain
depends on where the front ends up.

Near term today
High pressure building in today so expect a mostly clear sky
with temperatures pretty similar to yesterday. Generally should
see highs in the 30s to near 40 degrees.

Short term tonight through Wednesday
High pressure axis crosses the forecast area tonight which
should set the stage for the best radiational cooling night of
this air mass. Should see temperatures falling into the teens
and single digits, with subzero possible in the coldest
locations up north. For low temperature forecast I used a
combination of prior forecasts as well as knowledge of how the
last few nights temperatures have panned out.

With the high off to the east on Wednesday a southwest flow will
allow temperatures to warm up. More widespread 40s are likely on
Wednesday, and we could even see 50 degrees in southern new
hampshire.

Long term Wednesday night through Monday
00z operational models and ensemble guidance in relatively good
agreement with low pressure developing along the mid atlantic
coastline on Thursday. Solutions diverge there after however as
we move into Friday.

This storm will be driven by a closed upper low allow for rising
heights in the intermountain west, followed by the development
of significant troughing in the east. Whether or not short waves
phase during the late week cyclogensis period will be crucial to
this forecast.

The european model has done a decidedly westward shift from the
12z run while the canadian run has an intense low forming, but
well off the coast Thursday night into Friday. This westward
shift would allow warm air to quickly enter southern areas and
preventing much if any snowfall over that portion of our
forecast area. The elevated, northern terrain should receive the
most accumulating snowfall for this system which is typical for
this time of the year.

Confidence levels remain relatively low, both in terms of ptype
and precipitation amounts with this system. Confidence levels
will increase once the track and intensity forecasts become more
stable from model to model and run to run.

In any event, strong westerly winds will follow Friday night
through Saturday with scattered upslope snow showers continuing.

These will mainly be confined to the north. Below normal
temperatures for this time of the year will return to the
region.

Aviation 07z Tuesday through Saturday
Short term... With high pressure moving by we should see very few
clouds and light winds through Wednesday.

Long term... Conditions lowering to ifr in rain and snow with the
greatest chance for all snow over the elevated terrain in the
north Thursday. The low ceiling and visibilities will continue
into Friday. Scattered snow showers thereafter will be limited
mainly to areas of upslope high terrain.

Marine
Short term... High pressure crossing the gulf of maine will bring
light winds and seas. A southwest flow begins behind the high on
Wednesday.

Long term... Gale force southeasterly winds possible Thursday
night, followed by more strong, gusty winds developing from the
west Friday and Saturday.

Me... None.

Nh... None.

Marine... None.

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.
