Marine Weather and Tides
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.

Synopsis for the tidal potomac and md portion of the chesapeake bay.. A cold front approaching from the north will stall near the waters through Wednesday. Low pressure will track along the boundary and pass near the waters Wednesday. The front will then drop farther south Thursday. High pressure will briefly build toward the waters from the ohio valley Friday before moving into the western atlantic over the weekend.

High pressure remains centered off the coast today. A frontal
boundary drops into the area tonight and Wednesday, then settles
near the virginia north carolina border Thursday. The front
drops farther south into the carolinas Friday as high pressure
builds over the new england coast.
Near term through tonight
As of 400 am edt Tuesday...
the current surface analysis places high pressure
centered over the deep south, and a cold front is situated near the
ny pa border. Mostly clear, warm, and humid early this morning with
temperatures ranging through the 70s and dewpoints in the low mid
70s. Surface high pressure will weaken today with a lee-side trough
developing over the piedmont as the mid-level high remains centered
near the carolinas. Becoming hot and still humid later this morning
into early aftn. High temperatures in the mid 90s from central va
through SE va and NE nc combined with dewpoints in the low mid 70s
will result in heat indices of 105 to 108f. By later this aftn, the
mid-level ridge will breakdown as the aforementioned front drops
swd. Showers tstms are expected to develop in vicinity of lee-side
trough by mid-aftn, with this activity potentially organizing and
dropping SE into central and SE va later this aftn through evening.
Modest buoyancy along with increasing mid-level flow will result in
a marginal severe risk per SPC outlook, with the main threat being
damaging wind gusts. Highs today will be in the mid 90s, with upper
80s low 90s at the immediate coast. Lows tonight will mainly be in
the low mid 70s.
Short term Wednesday through Thursday
As of 400 am edt Tuesday...
the frontal boundary remains over the region Wednesday, with
another round of aftn evening showers tstms expected. Again, the
severe risk is marginal with damaging wind gusts the main
threats. Highs Wednesday will mainly be in the mid 80s to low
90s (upper 70s at the immediate atlantic coast of the md ern
shore). Lows Wednesday night will generally be in the low mid
70s. The front settles near the va nc border Thursday, with the
best chc of showers tstms shifting into SRN va NE nc. Highs
Thursday will be in the mid upper 80s (with upper 70s around 80f
for the immediate atlantic md coast).
Long term Thursday night through Monday
As of 350 pm edt Monday...
models show strong ridging aloft remains over the southeastern
us and gulf coast states Thursday evening with a trough exiting
the northeastern us while a closed low and trough are entrenched
over the central us. The ridge over the southeast and gulf
coast will remain entrenched for the extended period and the
central us trough will lift into the great lakes and
northeastern us before it begins to shear out. At the surface,
the models show a cold front sinking south through the area
Thursday night into Friday before washing out on Saturday. The
question is how far the front GOES as the GFS and ECMWF get the
front well into the carolinas. The models often struggle with
how far south the fronts get this time of the year. So have held
on to some pops in the southern portion of the CWA Thursday
night into Friday thinking the front will linger a little closer
than the models currently show. Once the front dissolves on
Saturday, the flow will return to a southerly direction as the
high to the NE retreats and the low pressure over the great
lakes heads toward SE canada. This will allow the warmer and
more humid air to return to the area. Temperatures will rebound
from the mid to upper 80s on Friday to upper 80s to near 90 on
Saturday. This day should have the better chance for afternoon
storms with the added forcing of the upper trough.
For Sunday into Monday will see a return of the heat and
humidity as the ridge over the SE us remains in place with the
models trying to break it down on Monday with a cold frontal
passage. Right now the models show a much more vigorous trough
over the great lakes and northeastern us which would suggest|
that the front would go through and would like generate some
convection along the boundary. So have increased pops back to
chance levels on Monday after reducing values to slight chance
on Sunday. Temperatures each day should be in the low to mid
90s. But will have to see if this trend of the models persist or
if the ridging over the SE us maintains it hold on the weather
and the fronts continue to stall out near the va nc region.
Aviation 11z Tuesday through Saturday
As of 710 am edt Tuesday...
high pressure is centered over the southeast CONUS as of 11z,
with a trough swinging across the northeast. Mainly clear with a
few high clouds this morning with a SW wind of 5-8kt. Sct-bkn
cu of 5-7kft are expected to develop by this aftn, with sct
showers tstms developing and expanding in coverage from ric-sby
later in the aftn, then shifting toward phf orf by evening,
with a lesser chc at ecg. Any showers tstms have the potential
to produce brief MVFR or ifr conditions. The wind will become nw
5-8kt this aftn, with the potential for locally strong wind
gusts in tstms. Showers tstms should diminish in coverage and
intensity later tonight.
A weak cold front will settle over the area Wednesday with
another round of aftn evening showers tstms expected across the
region. The boundary shifts farther S by Thursday, with the best
potential for aftn evening showers tstms mainly over SRN SE va
and NE nc. Mainly dry conditions are expected Friday as high
pressure over coastal new england results in onshore flow. The
potential for aftn evening showers tstms returns Saturday.
As of 440 am edt Tuesday...
no headlines in the short term today thru Wed night. Winds will
become W then NW at 10 kt or less this morning, as a weak
boundary crosses the waters. A weakening cold front then sags
south over the waters late this aftn into Wed morning, turning
winds to the NE (but still less than 10 kt). The meandering
front slowly lifts back north late wed, with onshore flow
gradually becoming SE by late wed, then ssw Wed night. This
same front then drops back south across the waters on thu, with
nnw winds around 10 kt becoming NE then E late Thu aftn into fri
morning. E winds 10-15 kt later Fri morning into Fri evening. Waves
1-2 ft thru Thu night, with seas 2-3 ft.
As of 800 pm edt Monday...

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.
