Marine Weather and Tides
Boston, VA

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

area forecast discussion

1004 am edt Mon may 21 2018

Today will be a pleasant spring day, with a fair amount of
sunshine, and warm temperatures. A frontal complex, will
approach the area late tonight, then move through on Tuesday.

This system, will bring our next shot of showers and a few
thunderstorms. Dry weather will return for Wednesday to

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

fog burned off by 9 am. A thin overcast will remain for the rest
of the day before thicker clouds come in this evening. Upped
temperatures a few degrees to be closer to guidance which has
been close on days like today. Rain showers move in after

415 am update... Goes-east imagery, surface observations, and
web cams, all show areas of stratus clouds and fog, across much
of cny and nepa early this morning. We expect it will take until
the 8-9 am time frame to burn the low clouds and fog off.

Thereafter, we should enjoy filtered sunshine through thin high
cloudiness for much of the day. Such insolation, combined with
the beginnings of low-level warm advection, should allow highs
to climb well into the 70s for most locales.

Short term 6 pm this evening through Tuesday night
430 am update... Things quickly go downhill tonight, as the next
short-wave approaches from the ohio valley, along with an
associated surface low from the central great lakes region, and
a warm frontal boundary. Deepening moisture and increased forced
ascent should bring a period of steadier rain into the forecast
area from west-east after midnight. Some elevated instability
could sneak into our far western and southern zones in the pre-
dawn period, so we inserted the mention of isolated thunder in
these areas. Lows by daybreak Tuesday will range in the 50s.

On Tuesday, the above mentioned surface low is progged to track
right across ny state, with the warm front sluggishly crossing
the finger lakes region and portions of nepa. It is these areas
that should at least briefly emerge into the warm sector, with
some developing instability (perhaps on the order of 500 j kg
ml cape) and thunder potential. Farther to the east, it is
quite possible (perhaps likely), that the warm front will not
make it, with an occluded frontal passage by early evening.

Thus, these latter areas (namely the western catskills,
portions of the poconos, and places otherwise east of the i-81
corridor in cny) will be cooler and more stable, with only a few
rumbles of thunder anticipated, at worst. Overall, clouds and
precipitation will keep temperatures down on Tuesday, as
compared to what we'll see this afternoon. Afternoon highs
Tuesday will range from the lower 60s over the higher terrain of
the catskills, to the lower 70s over parts of the finger lakes
region, as well as the wyoming lackawanna valleys in nepa.

Tuesday night, any lingering early evening showers should
quickly push off to the east, as the trailing cold occluded
surface boundary sweeps through. Clouds may be slow to depart
though, with weak mixing post frontal passage, and the
likelihood of trapped moisture below a subsidence inversion
aloft. Our western areas (the finger lakes central southern tier
regions of cny) will likely be the first to see partial
clearing in the pre-dawn hours Wednesday. Lows by daybreak
will again range in the 50s.

Long term Wednesday through Sunday
325 am update...

little change from prior forecast, with generally dry and
pleasant period Wednesday through Friday, followed by increasing
chances for showers and perhaps thunder over the weekend.

Canadian gem is still fairly wet Saturday, but trend in ecmwf
and especially GFS is towards holding things off one more day.

Second half of the weekend looks more unsettled than the first.

Previous discussion...

warmer Wednesday with fewer clouds as high pressure builds in
late in the day. Highs in the 70s.

A large area of high pressure moves across the area Thursday
then weakens Friday off the coast. Both days will be dry. Highs
Friday get into the upper 70s to around 80.

Rain showers and possibly thunderstorms return for the weekend
probably starting Saturday afternoon. An upper level trough
moves slowly out of the plains with a surface cold front ahead
of it. There will be a deep southerly flow of moisture from the
gulf into the ohio valley and northeast us. This will keep
temperatures in the 60s and 70s with some humidity.

Aviation 14z Monday through Friday
10am update...

valley fog is gone andVFR expected the rest of the day into
tonight. Fog burned off between 11 and 1320z.

12z update...

moisture from recent rains, along with mostly clear sky and
decoupled near calm wind, allowed for solid fog development
night for all terminals except ksyr overnight. Lingering
restrictions will be possible initially at 12z but rapid
improvement will occur. Dry high pressure will provide for a
very quietVFR day with just some scattered high clouds above 20
kft agl. Winds generally variable or light northwest around or
less than 5 knots, then becoming southeast tonight. Clouds will
develop and gradually lower tonight, with rain and perhaps minor
restrictions arriving at several terminals towards 12z Tuesday.


Tuesday through Tuesday night... Occasional restrictions in
periods of showers and thunderstorms.

Wednesday through Friday... MainlyVFR.

Bgm watches warnings advisories
Pa... None.

Ny... None.

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
