Marine Weather and Tides
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

352 pm edt Thu jul 20 2017
Widely scattered thunderstorms across the region will weaken
quickly after sunset tonight. Temperatures will slowly fall back
into the 60s for most locations. Friday temperatures tick up a
degree or two... As westerly... Offshore flow dominates.
Temperatures remain warm into the weekend. A low pressure
system may bring cooler weather and more potential for rainfall
Sunday night into early next week.
Near term tonight
Jet streak moving into the northeast is leading to a broad area
of upper divergence over the forecast area this afternoon and
into the evening. Given the warm and humid air mass in place at
the surface... There is sufficient instability for thunderstorms.
Areas of enhanced surface convergence... Like heating of the
terrain or sea breeze boundaries... Will be the most likely focus
for convection. There is also a S WV trof approaching that may
allow convection to persist across the NRN zones past the loss
of daytime heating... But otherwise diurnal cooling will signal
the weakening of most storms. Until that time any stronger
updraft could produce a strong wind gust or two given effective
shear around 35 to 40 kts.
Some patchy fog is possible late tonight... Especially any areas
that picked up a little rainfall today. With the boundary fairly
stagnant over the area... Low temps will be similar to the past
couple of nights.
Short term 6 am Friday morning through Friday night
Fri expect similar temps overall... As mid level temps remain
fairly consistent. Wly flow may allow for a little extra
downslope warming in the favored locations. Another weak wave
is forecast to approach the area during the day... And will
likely spark another round of widely scattered showers or
storms. We also take another step down in humidity... And fri
night should be a little cooler than the previous days.
Long term Saturday through Thursday
The models remain in decent agreement on the long wave pattern
through the first half of next week. Thereafter, we continue to
see big differences emerge regarding the degree of residual
troffiness here in new england downstream of the central conus
ridge. Overall, we're likely to see both heights and temperatures
run below average for much of the extended period. We begin the
period with a westerly flow and a broad low amplitude trough here
in new england. The weak ridging promised for Sunday in response
to digging upstream shortwave energy over the great lakes has all
but disappeared. The upshot is that the baroclinic zone will stall
further north over new england... And any clearing will be confined
to the international border area as well as our eastern maine zones
as high pressure over eastern canada briefly noses into the forecast
area. By the start of the new work week, this shortwave energy has|
carved out a sizable trough across the great lakes and northeast
conus. The trough axis will inch eastward across the region through
the first half of next week keeping the region seasonably cool
and unsettled. In the dailies... We begin the period with a cold
front stretching from our international border area through northern
maine into new brunswick. This cold front will settle south across
the region Saturday and Saturday night with clouds and scattered
convection. By Sunday morning... The boundary will be stalled
across southern new england with any clearing confined to the
international border area and our northern and eastern maine zones
as high pressure briefly noses in. Elsewhere... It'll be a mostly
cloudy day with the best chance for showers across southern and
western new hampshire. By Sunday night... The frontal zone will
ride back north with attendant cloud shield as well as increasing
pops and cool unsettled weather in response to evolving upper
trough. This cool unsettled weather is expected to linger through
the first half of the upcoming work week.
Aviation 20z Thursday through Tuesday
Short term... Widely scattered tsra will continue into the
evening... Weakening after sunset. Confidence is too low to
include at any of the terminals with significant lead time.
OtherwiseVFR conditions return tonight. Leb and hie will be
clear... Cool... And calm enough to see some fog possible after
midnight.VFR conditions continue fri... Though an afternoon wave
may spark some shra or tsra in the mtns. Hie could see
precip... But again confidence is low.
sat... Sct MVFR in -shra -tsra.
Sun - tue... Areas of MVFR in -shra -tsra with LCL ifr in coastal
stratus and fog.
Short term... Winds and seas are expected to remain below sca
winds and seas are expected to remain below small craft threshold
through the period.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. 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 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.
