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.

Synopsis for the tidal potomac and md portion of the chesapeake bay.. A cold front will approach from the west today and cross the waters tonight. Low pressure will develop offshore Wednesday. High pressure will return for late in the week. A small craft advisory may be needed for the waters late Tuesday night through Thursday.

High pressure will slide offshore today into tonight. A cold
front crosses the area Wednesday morning with low pressure
moving northeast along the coast Wednesday afternoon and night.
A second surge of arctic air pushes across the area Wednesday
night into Thursday before temperatures moderate into next
Near term until 6 pm this evening
Current WV imagery and model analysis depicts a potent upper
trough digging across the midwest, with broad SW flow aloft from
the gulf coast across the mid-atlantic and into coastal new
england. At the surface, 1040+ mb high pressure is retreating to
the NE over ERN canada, but the surface ridge axis still
extends well to the SW into the mid-atlantic. Meanwhile, an
inverted trough is located off the coast, and light NE flow
associated with this feature has pushed a marine layer inland
with fog and stratus covering much of the area with the
exception of the far WRN piedmont. Temperatures early this
morning range from the upper teens over the piedmont to the low
30s along the coast.
High pressure will gradually erode today with the inverted
trough still lingering off the coast. Therefore, fog and stratus
will be slow to erode this morning, and mixing will be limited
today. This will offset modest mid-level WAA and high
temperatures today will only rebound to the low mid 40s, which
are near seasonal averages.
Short term 6 pm this evening through Thursday
The potent upper trough will pivot sewd tonight across the ohio
valley and into the cumberland plateau, with the cold front
pushing across the mountains and into the piedmont by 06-12z
Wednesday. The vigorous upper level feature will continue to
trundle ewd across the region Wednesday as the cold front
gradually pushes through the region with snow overspreading the
region and affecting the commute Wednesday morning across wrn
and central portions. 16 00z gfs ECMWF nam cmc demonstrate
decent agreement with this feature, with some slight timing
differences in the latter stages, mainly 18-00z Wednesday with
the ECMWF cmc slightly slower. Given this, pops have been
increased to categorical across the piedmont after 06z tonight
into midday Wednesday, and for central and s- central va
Wednesday morning. Likely pops have been maintained for SE va ne
nc, with likely pops for the middle peninsula northern
neck lower ERN shore tapering to chc for the lower md ERN shore.
Model consensus supports QPF of 0.2-0.3" across the piedmont
and s- central va and northampton nc, bordered by 0.1-0.2" from
central va to SE va and NE nc, with 0.1" or less farther ne.
Expect some variability in slrs, but generally ratios of 12-15:1
are expected during the highest pops, which supports 2-4" of
snow across the piedmont, with 1-3" for the i-95 corridor of
central and s-central va into northampton nc. Given this, a
winter weather advisory has been issued for these locations
generally beginning late tonight and extending into Wednesday
aftn. There is the potential for a narrow band of negative epv
over the SW piedmont and there could be a very narrow corridor
of 4-6" of snow. This would be very localized and hard to pin-
down, so there is no need for a watch or warning at this time.
We will need to watch for sharpening axis of f-gen oprh depicted
by the high-res NAM as it may portend to a period of moderate
snow even into hampton roads Wednesday aftn. No advisories have
been issued yet for hampton roads, but may eventually be
necessary as it could affect the aftn commute. High temperatures
will generally be 30-35f, but will likely fall into the
mid upper 20s across the NW half of the area during the aftn.
The sky will clear quickly Wednesday night as a quick shot of
arctic air surges into the region. Shallow mixing is expected to
persist overnight, which should inhibit temperatures from
plummeting too far. Still cold nonetheless with lows in the mid
teens inland to the upper teens low 20s for coastal SE va NE nc.
Mid-level WAA resumes rather quickly Thursday with 850mb
temperatures of -2 to -4c at 12z warming to +4-6c by 21z. A cold
start to the day, limited mixing, and mid-level WAA should
result in rather stable lapse rates and surface high
temperatures should only reach the upper 30s to low 40s.
Long term Thursday night through Monday
Pattern change looks to occur during the medium range period with a
significant warmup expected through the upcoming weekend early next|
week. It will still be on the cold side Thu night with sfc high
pressure centered across the deep south, and one last upper trough
moving SE through the great lakes and off the new england coast fri
morning. Mostly clear skies will prevail over the local area with
lows mainly in the 20s though depending on remaining snow cover,
some upper teens will be possible across interior southern va.
Latest gfs ECMWF cmc depict the upper trough moving well off the new
england coast Fri with a broad upper level ridge building over the
eastern CONUS Fri aftn through the weekend. Expect continued dry
conditions with warming temperatures, highs in the upper 40s lower
50s fri, rising well into the 50s (possibly near 60f) sat, and into
the 60s (except at the immediate coast eastern shore) for sun. Lows
fri night Sat am in the mid 20s to mid 30s, and Sat night Sun am in
the 30s to around 40f. Some timing differences arise by sun
night mon, but overall expect increasing clouds ahead of the next
front Sun night and will carry a chc for showers Mon mon night. Mild
with lows in the 40s and highs Mon mainly in the 60s.
Aviation 09z Tuesday through Saturday
Wide variety of conditions tonight with primarily ifr to lifr
ceilings for the eastern half of the CWA and mainly clear
skiesVFR west of i-95. Fog has also formed mainly east of i-95
across the area of low ceilings, fog may be locally dense at
times. Conditions slowly improve during the day today with lower
ceilings expected to linger near the coast through the early
afternoon. Conditions will deteriorate once again Tuesday night
as a potent upper level trough brings thickening and lowering
clouds. Light winds will average 5 knots or less for the most
part which will tend to keep an onshore flow at the immediate
coast, but shifting to the S well inland.
Outlook: expect flight restrictions on Wed with snow showers as
clipper and associated cold front crosses the region. Clearing
wed night with breezy N winds near the coast. PredominateVFR
then likely Thu Fri as the trough ejects NE offshore.
Marine dense fog advisory is in effect until 10 am est for all
the waters minus the northern ocean zones. Cams sfc obs continue
to show visibilities under 1 nm. Fog will slowly dissipate
through the morning.
High pressure centered over eastern canada and ridging to the
ssw along the piedmont has resulted in nne winds of 10 to 20
knots across the waters this morning. Seas range generally range
from 4 to 7 feet and waves range from 1 to 2 feet (up to 3 feet
at the mouth of the bay). Scas have been extended for the
coastal waters as seas will remain at or above 5 feet,
especially out 20 nm, today. Winds are expected to diminish this
afternoon as a weak surface ridge settles near the coast. A
surface cold front crosses the the coast Tuesday night with
strong CAA lagging behind until the upper trough arrives
Wednesday evening into Thursday. Winds become NW Wednesday and
increase to 15 to 25 knots by Wednesday evening. Scas were
extended over the coastal waters through Thursday due to current
seas and anticipated wind seas with the next event. Scas will
likely be needed for the bay as well Wednesday night into
Thursday. High pressure settles over the area by Thursday
afternoon and Thursday night, and then slides off the southeast

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.
