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.

short term today through Sunday ...
to our north, a weakening closed low is pushing into the ohio valley
this morning. While this low will track north of our area today,
midlevel energy has begun to bring an increase in shower coverage
over alabama and north georgia. Coverage of showers should continue
to increase relatively quickly through the remainder of the morning,
initially across north georgia and transitioning south and eastward
through midday into the afternoon. The potential for isolated
thunderstorms will begin to increase around sunrise and transition
into central georgia by afternoon. Instability will increase into
the 1000 j kg range this afternoon, but shear is unimpressive, and
no strong severe thunderstorms are expected.
While rain chances will generally decrease from north to south
through the afternoon, the isolated shower and thunderstorm
potential will return across far north georgia this evening as the
aforementioned dampening low traverses the appalachians. Any
isolated convection will then gradually taper off through late
evening as the low exits east. The associated weak surface front
will push into central georgia and stall. The remainder of Saturday
night into Sunday morning will be dry until the stalled front begins
to lift back northward as a warm front late Sunday. As this occurs,
shower and thunderstorm coverage will begin to quickly increase by
Sunday evening. This will lead into a much more active and stormier
period Sunday night into Monday.
Temperatures will remain above normal today through Sunday with
highs generally in the 70s and low temperatures Sunday morning
ranging from the upper 40s far north georgia to the upper 50s to
near 60 in central georgia.
long term Sunday night through Friday ...
a fairly aggressive system making its way into our area for the
beginning of the extended forecast. High pressure builds back
into the region for the middle to end of the 7 day forecast.
The cold front that moves through the area today moves back
northward as a warm front Sunday night with the next cold front
directly on its heels. Beginning Sunday night Monday morning,
moist southwesterly flow sets up across the area as the warm
front moves into central portions of the state. Instability
indices increase across the state as a a strong piece of southern
stream energy interacts with the warm front. This will produce
periods of locally heavy rainfall and some isolated to scattered
thunderstorms. Currently, the axis of heaviest rainfall is progged
to be across central and south ga. Another bout of moderate to
locally heavy rainfall is possible Monday night into Tuesday as
the cold front moves through.
As far a S the possible severe weather from this system the
models are coming into a bit of better agreement as far as timing
and intensity. Instability peaks Sunday evening then weakens
Sunday night through early Monday morning. This should keep any|
thunderstorms to a minimum but would not be surprised to see
strong thunderstorm during this time frame. The mid level lapse
rates stay fairly steep... And some surface instability will be
present so can not rule out a severe storm. Instabilities
increase during the day Monday with MUCAPE increasing into the
800-1800j kg range and shear and lapse rate values staying up as
well. There is not as much deep moisture present but with a
secondary cold front sweeping around the parent low and daytime
high temps in the 60s and 70s... The atmosphere will be primed for
severe storms to develop. SPC also agrees and has placed the
majority of the state under a slight risk for day 3 with NW and
west central ga under a 10 percent hatched area for significant
severe weather. Will be keeping a close eye on this over the next
behind the cold front, for the latter half of the week, colder than
normal temps will return. Will most likely have to issues some
frost freeze products Wed thu.
scattered showers and a few thunderstorms have begun to overspread
the area this morning. As rainfall coverage has increased, so have
MVFR ceilings. Best window for showers and isolated -tsra
activity will be through around 15z at atl area sites with window
a bit later at mcn csg. Primarily MVFR ceilings this morning will
likely trend towards ifr ceilings by mid-morning as showers push
eastward. Ifr ceilings should scatter and lift through the
afternoon and evening hours. There is some potential for at least
MVFR clouds to return by Sunday morning, especially at csg mcn.
Winds will remain on the west side through the period at 5-11kts.

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.
