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.

short term today through Thursday ...
a broad scale view of the CONUS around 0730z this morning depicts an
area of low pressure centered roughly near the mt dakotas border
with quasi zonal-flow located downstream across the midwest and gl
regions. Weak ridging still evident over the far southeast with a
stronger ridge building across the ca az mexico baja vicinity. In
the lower levels... Nearly stationary boundary still evident across
the oh valley westward into the central plains. Weak high pressure
still located south of the boundary across the southern us with a
weak low offshore N carolina and associated troughing present down
the leeward side of the appalachians.
This morning a very weak shortwave trough across northern al central
tn is associated with some isolated shower activity to our west. As
this shortwave pulls NE over the next several hours... Rain chances
should remain north and west of the area. As we go more into the day
today... Most of the area will be protected by whats left of the
mid upper ridge. However..Current moisture over northern ms has
potential to make it into north georgia this afternoon in the form
of isolated to scattered showers and thunderstorms. Elsewhere... Very
isolated afternoon evening single cell convection is expected given
strong daytime heating... Tho somewhat drier air under the ridge
should actually keep most of the area dry today.
By tonight... Previously mentioned low across mt dakotas will dig
south into the mid ms valley and strengthen as it encounters the
stationary sfc boundary. This along with a lifting shortwave over tx
will pull tropical moisture north northeastward over weakening se
ridge. As the ridge breaks down further through the day
Thursday, an open lane for moisture transport will exist. This
should allow for much better convective coverage by Thursday
afternoon, particularly across north georgia. Evidence of mid
level flow increasing to near or just over 25-30kts should support
the potential for clusters of storms to develop and thus
increasing the chance to see some isolated strong severe activity.
long term Thursday night through Tuesday ...
extended period begins with short-term ridge really losing its
hold over the region as low pressure traverses the midwest and
approaches the state. Steady stream of moisture remains present
over the region through late week and into the weekend as parent
low enters the ohio valley region and disturbances swing through
the base of the trough. Have generally gone with likely pops over|
far north georgia and good chance elsewhere as these features will
enhance precip coverage. Expect best coverage to still be
associated with daytime heating, but it's unlikely precip activity
will completely shut off through the overnight periods.
Upper level zonal flow remains over the region in the wake of the
low. By early next week, weak, broad high pressure sets back up
with plenty of moisture trapped under the ridge. As a result,
expect seasonal thunderstorm chances each day.
Temperatures will remain warm through the extended period. Highs
in the upper 80s to mid 90s will combine with dewpoints in the 70s
to produce heat index values in the upper 90s to low 100s,
particularly over portions of central and eastern georgia. During
prolonged periods outdoors, take frequent breaks and drink plenty
cumulus deck sct040-050 should develop during the afternoon across
most of the TAF sites. Clouds should dissipate during the early
evening. Only isolated thunderstorms possible this afternoon and
evening and probability too low to include in tafs. Will watch and
see if and where they develop. Winds should remain mainly nortwest
to north and diminish after 00z. Winds becoming more southwest
tomorrow. Expect an increase in shower and thunderstorms development

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.
