Marine Weather and Tides
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.
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.

Synopsis for the tidal potomac and md portion of the chesapeake bay.. An expansive area of high pressure will build eastward from the great lakes region through the weekend, moving off the new england coast early next week. An area of low pressure over the deep south will approach the region mid week. Small craft advisories may be needed late Monday into Tuesday.

Cool and dry conditions continue through the weekend as high pressure
becomes centered from the great lakes to the mid atlantic region.
Moisture will increase as low pressure tracks from the gulf coast
states northeast up along the east coast late Monday through Wednesday.
Near term until 6 am this morning
As of 830 pm edt Friday...
current analysis continuing to reflect a benign, quiet wx
pattern across the eastern third of the conus. Little change to
the going forecast, with clear skies and cold temperatures
overnight. Sfc dew pts are genly rising W the lighter winds and
even though actual temperatures overnight will be similar to or
slightly warmer than last night, the potential for at least
patchy frost will be greater. It is still fairly dry however,
and do not anticipate the frost to be widespread significant
enough to issue any frost freeze headlines, but will make
mention in the hwo once again. The timing would be from about 3
or 4am through 7 to 8 am, primarily over the more rural
locations of central va, interior eastern SE va well removed
from the coast, and interior md eastern shore. Lows will range
from around 32 f in the coldest spots to 33-38 f for the
majority of the cwa, and locally in the lower 40s immediate
coast of SE va NE nc.
Short term 6 am this morning through Monday night
As of 335 pm edt Friday...
cool high pressure builds in from the NW early in the period,
before sliding offshore Sunday into Sunday night. This will
bring a mainly clear sunny day on Saturday, with gradually
increasing clouds Sunday afternoon and night. N or NE winds 10
kt or less veer around to the sse Sunday through Sunday night,
bringing gradually moderating temps.
Have gone on the high side of guidance given sunny dry
conditions on Saturday, with expected highs in the upper 50s to
lower 60 at the coast, mid to upper 60s inland. Mainly clear and
not as cold Sat night, with lows mainly in the lower 40s.
Gradually increasing clouds but still partly to mostly sunny on
average with highs mainly ranging thru the 60s. Lows in the mid
40s to low 50s Monday morning.
By Monday morning, next weather system currently over the desert
southwest will have pushed east toward the gulf coast region.
Models are in general agreement that the trough will gradually
dampen, with the closed low opening up as the upper trough
traverses the southern tier of states over the weekend, with a
weak inverted trough developing over the southeast into Monday
morning. Given the antecedent dry conditions and the slow
evolution of this system, have kept Monday dry across the local
area, despite increase in cloudiness. May be a few light rain
showers possible across the i-85 corridor, but will hold pops at
slight chc or less. More clouds than Sun will keep temps a few
degrees cooler into the low to mid 60s across the SW tier.
Otherwise, partly sunny across the northern tier. Rain chances
steadily increase Monday night across the piedmont, with precip
spreading nne into the area into Tuesday morning. Lows mainly in
the upper 40s in the piedmont to low 50s across SE coastal
Long term Tuesday through Friday
As of 410 pm edt Friday...
rain will move into the area from ssw to nne during the day on
Tuesday as the upper wave and associated sfc low pres push E ne.
20 12z gfs ECMWF cmc are in good agreement that the area of light to
moderate rain will cover the entire CWA by late afternoon on Tuesday
and last through around 12z wed. Given the agreement between the
most recent suite of guidance, have increased pops to 60-70% for the
entire CWA tue-early wed. Due to the rain, high temperatures will be
be in the low 60s for the bulk of the CWA on Tuesday. After the sfc
low tracks through eastern portions of the CWA Wed am, the main area
of rain will exit the region. A few showers will still be possible
during the day, but temperatures should warm to near 70 on Wednesday
if the rain exits early enough (this looks more likely in southern
parts of the cwa).
12z GFS cmc track another sfc low weak cold front through the area
Thursday-Friday am, but ECMWF does not have a rainy solution. Thus,
have kept pops at or below 40%. Highs around 70 lows between 50-55
expected thu-fri. An upper trough amplifies over the eastern us
Friday pm into next weekend as sfc low pressure is forecast to
deepen over the northeastern us at the same time. This will set the
stage for another chance of rain late Friday as well as below
average temperatures next weekend.

vfr conditions through the 06z TAF period. Winds have
diminished significantly since sunset and now avg 5 kt or less

less than 10 kt, genly from the N to NW but will shift onshore
to the E NE near the coast in the aftn. Expect skc through most

no headlines in the short term tonight thru sun. High pressure
builds in fm the NW tonight. A northerly surge is expected
later tonight, but this surge will be sub-sca. High pressure
will then build over the region Sat and Sun resulting in benign
marine conditions. The high pushes off the SRN new england
coast early next week, as low pressure moves fm the gulf coast
states to off the SE coast Mon into wed. This will result in
increasing onshore flow. An E wind is expected to reach 10-15 kt
on mon, then 15-25 kt late Mon night Tue tue night. Onshore
flow will result in seas building to 6-10 ft by Tue night, with
4-5 ft waves in the mouth of the bay. Broad low pressure
crosses the region wed, with the wind becoming wnw in the wake
of the low.

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.
