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.

A weak front will lift northeast across the area late tonight
and early Friday with clouds and a few snow showers. A milder
flow and above normal temperatures follow late Friday into the
upcoming weekend. A storm system may will likely affect the
region early next week with mixed precipitation and rain.
Near term until 6 am Friday morning
Quick update to to tweak temps tds rh sky grids. Low level
moisture continues to hug the connecticut valley and the
mountains of me nh. At the same time weak disturbance spreading
high and mid level clouds into western zones and these will
continue to over-spead the region through the early morning
hours. Radar showing some weak returns associated with this
feature moving through the eastern great lakes but not much
showing in surface obs. May see a stray flurry in northern zones
after midnight but should not amount to much and low chance
pops in current forecast should be sufficient. No other changes
planned for current forecast attm.
a fairly strong short wave trough over the great lakes states
as of 20z will continue to move eastward tonight and cross the
region late tonight into early Friday. The airmass in advance of
this short wave is quite dry so we do not expect much in the way
of precipitation with it. However, we do think that forcing will
be strong enough to allow for a band of snow showers to cross
the region late tonight into early Friday morning. There could
be a coating in spots, perhaps even as far east as the coastal
plain. The best chance will be across northern nh. The passage
of this short wave trough and possible attendant snow showers
would be roughly between 09z and 13z.
In the meantime, mostly clear skies downwind of the mountains
will continue into this evening before clouds increase after
midnight. Across coos county nh northeastward into the western
me mountains, stratocu and sct snow showers should continue well
into the evening hours.
Short term 6 am Friday morning through Friday night
Any snow showers will quickly end early Friday morning followed
by partly sunny skies (there will be periods of clouds with
ample 850mb moisture around) with highs about 5 degrees warmer
The warm air advection regime continues Friday night as a
southwesterly low level jet strengthens. It should however
remain dry in most locations, except for the far northern zones
where snow showers will be possible.
Long term Saturday through Thursday
Scattered showers and mixed cloud cover will continue into the
weekend for the region, mainly in the mountains. A positively
tilting and shearing out system moving through central quebec
will push a cold front into northern sections on Sunday. Ahead
of the front timing will cause high temperatures to occur early
during the day Sunday for northern sections, with highs|
occurring in the afternoon for the central and southern zones.
Some warming into the 40s is likely for a few spots in SW flow
ahead of the front over southern nh SW me, but models have
trended cooler with time. Ensemble members are continuing to
show very cold air arriving for the border towns of northern nh
and maine during the evening Sunday and into Monday, with temps
early Monday morning in the single digits for the immediate
border area. The wedge of cold air will dam along the mountains
and foothills with teens and 20s most other spots.
On Monday and even into Monday night the cold wedge will
moderate quite a bit but we will be much closer to normal
values. Monday night into Tuesday a large closed low will
eject out of the great lakes region. Warm air advection
spreading over the colder air at the surface may initially
bring some light mixed precipitation to the region before
changing over to primarily a snow rain event. On Tuesday
increasing southerly flow temperatures will change precipitation
over to rain for a portion of the interior as well.
Aviation 04z Friday through Tuesday
Short term through Friday night ... MainlyVFR tonight through
Friday night. However, a period of MVFR conditions are possible
between 09z and 13z tonight. At hie, MVFR conditions will be
more prevalent this evening into tonight.
Long term... Possible MVFR conditions Saturday into Sunday with
scattered snow showers across northern areas... Mainly affecting
hie... OtherwiseVFR during this time period. Ceilings and
visibilities will be lowering Monday night into Tuesday as low
pressure forms along the mid atlantic region and moves north. Sw
to W winds will gust to near 20 knots or so Saturday before
decreasing. Gusty SE S winds are expected Tuesday.
Short term through Friday night ... Expect winds and seas to
remain below SCA thresholds through Friday. However, winds are
expected to increase Friday night as low pressure passes by to
the north. SCA will likely be needed for later Friday night.
Long term... Gusty southwesterly winds becoming westerly by
Saturday with speeds diminishing by the afternoon after being at
high SCA to borderline gale levels for the outer waters. Waves
also decrease from west to east to less than 5 ft by evening.
Strong gale force winds may develop next Tuesday into Wednesday
as low pressure develops to our west. Winds drop closer to sca
criteria for Thursday and Friday.
River flood warning for the kennebec continues as the river
fluctuates near flood stage because of tidal influence near the

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.
