Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

728 am edt Fri mar 22 2019
A late season winter storm will affect the area through
Saturday morning with valley rain and snow, and heavier mountain
snows. Mainly quiet and seasonable weather returns by Sunday
before a cold front ushers in much colder air for Monday into
Tuesday of next week. By later in the work week temperatures
Near term through tonight
All winter storm warnings and winter weather advisories remain
in effect for through Saturday morning...
as of 710 am edt Friday... The forecast remains on track in
regard to temperatures dewpoints and expected overall rain snow
totals as of 700 am. I did adjust pops somewhat to incorporate
latest hrrr guidance which is handling the current evolution of
pcpn pivoting north and west across our area better than prior
guidance. This shows some waxing waning of coverage through the day
as primary system consolidates offshore. Have a great day.
mainly a persistence forecast in regard to the overall weather
theme over the next 42 hours as deepening coastal low pressure
lifts northeast through the region. Still a complex evolution of
this system as competing upper closed lows consolidate over
time while current surface center near kacy transfers energy
further east near the benchmark which will take over as the
primary. A such most of the forecast effort overnight was to
tease out small scale details in p-type pop wind fields. Our
idea of increasing coverage of valley rains or mixed rains snows
and higher elevation snows today still looks good with highest
probabilities of accumulations generally above 1000 feet. The
devil lies in the details of course and given p-type will be
heavily governed by near surface temperatures any dynamical wet
bulb cooling processes could cool values just enough to cause
some variability at times in the valleys. Similar to last night
i leaned on the colder side of guidance and have a hard time
buying met mav guidance showing temperatures rising into the
lower 40s for example at kbtv on developing northerly flow this
afternoon. Used a multi-model blend including some raw model
output and 20% of our prior official data to yield highs ranging
through the 30s today depending on locale.
By later this afternoon and especially into this evening the now
consolidated and fairly deep surface low center will be pushing into
the gulf of maine or near the maine mid-coast. This will allow back
side deformational processes to blossom while winds trend
north northwesterly and increase steadily under a tightening
pressure gradient. Surface temperatures will begin to slowly cool
allowing a transition to all snow over time. As the night progresses
the snowfall will take on an orographic character as the surface low
begins to pull slowly away and become heavier at times. Our
messaging continues to highlight this period (600 pm to 800 am) as
the most impactful when the combination of moderate to locally heavy
snow and gusty winds lead to difficult travel and isolated power
outages. Our storm total snowfall was modified slightly to show a
sharper orographic character but the overall idea remains the same
with advisory areas seeing 2-7" and warning areas receiving a
general 6-12". The northwestern slopes of the adirondacks and spine
of the greens should see the heaviest totals from 10-18". Low
temperatures again a blend of guidance similar to that used for
today's highs - upper teens to mid 20s.
Short term Saturday through Sunday
As of 345 am edt Friday... On Saturday occluded surface low
pulls away fairly quickly given the lack of downstream blocking
and progressive nature of the upper flow pushing in from the
west northwest. Steadier light snows early taper off by mid-day
if not sooner with skies trending partly to mostly sunny from
mid afternoon onward. Highs will be on the chilly side from the
upper 20s to mid 30s under an abating but still gusty northwest
Quiet weather then returns for Saturday night into Sunday as surface
high pressure builds to our south and synoptic flow trends
southwesterly over time. Low temperatures to bottom out in the upper|
teens to mid 20s (near normal) with highs on Sunday returning,
albeit briefly, to milder levels in the 40s. By later in the day on
Sunday a strong polar front will approach the region from the north
along with increasing clouds and chances for rain snow shower
Long term Sunday night through Thursday
As of 345 am edt Friday... A cold front moves southward from
canada into the region Sunday night rather quickly and is south
of the CWA late Monday morning. Precipitation will be light and
scattered and mainly across northern counties with a mix of rain
and snow showers early on depending on elevation before
trending to all snow early Monday morning. QPF will not be
significant with up to a tenth of an inch of precip with an inch
or so of snow in the north to a trace in the south. Mountains
could be a bit more with a few inches of snow possible. High
temps will be in the 30s.
Tuesday and Wednesday will be cold and dry as a canadian airmass
moves south under high pressure and northwest flow aloft. Skies will
be mainly sunny but highs will in the mid 20s to lower 30s Tue and a
bit milder on Wed with highs mostly in the 30s. The coldest morning
looks to be Wed with lows from 5 to 15.
An upper level ridge moves across the region late Wed and into thu,
which will bring a reprieve from the cold as temperatures return to
seasonal levels by Thursday with highs in the 40s near to near
Aviation 12z Friday through Tuesday
Through 12z Saturday... A mix of MVFR to lifr currently across
the cwa. We will see a trend toward more widespread ifr lifr
cigs vsby after 15z. N-nw winds will increase to around
10-12kts areawide Friday afternoon and then see gusts of
20-25kts and some isolated 30kts after 21z. All stations can
expect periods of brief heavy snowfall which will bring
conditions to lifr. Anticipate increasing impacts to aviation
ground ops from the middle of the of the TAF period onwards
(late aftn- eve Friday through Sat morning).

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.
