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.

Short term today through Friday
The upper ridge builds over the southeast today... Keeping a very
warm air mass in place. Still no real triggers for convection except
diurnal heating so isolated to scattered thunderstorms can be
expected. Afternoon pops have been kept in the low chance range. A
front should sink into the tn valley late tonight... So have held on
to low pops through the overnight hours for north and west areas.
Better chances for convection expected for Friday as the surface
boundary pushes into north ga.
Afternoon temperatures should again be very warm today. Nudged the
numbers up a degree or two especially for east central areas. This
puts heat index values 105 to 107 in a small area over the east
central counties for a couple of hours this afternoon. Too
borderline for a heat advisory. Suspect the dew points may mix out
to be lower than forecast. Also... Any convection that develops could
affect these values.
Long term Friday night through Wednesday
A trough of low pressure will dig into the great lakes region to
start the long term, pivoting through nova scotia by late Sunday.
At the surface, a trailing front associated with the trough will
start to move through the region, eventually stalling across
central ga by Saturday afternoon. High pressure will build into
the northern half of the region through the remainder of the
weekend, before the front gradually lifts north Monday into
Tuesday. Another trough and surface front will approach from the
north by mid-week.
Expect residual scattered showers and thunderstorms Friday
evening well ahead of the surface front approaching from the
northwest. The front will cross the northern portions of ga
Saturday morning, eventually becoming stalled in central ga. This
will be the catalyst for thunderstorm development during the
afternoon and evening hours. With surface high pressure building
in from the north, the front remains stationary through Sunday,
perhaps shifting ever so slightly northward. This will once again
be the axis by which we see better coverage for convection during
the afternoon. The mid-level ridge starts to build back into the
region by early Monday with the surface high slowly moving off the
mid-atlantic coast. So, while this isn't typically the set up for
widespread convection, the stationary boundary will still be
enough convergence to generate thunderstorms by Monday afternoon.
This may wreak havoc for those wanting to witness the solar
eclipse. As it stands, it looks like the better cloud and
precipitation coverage will be along and south of i-20 as models
are trying to place the front in this general vicinity. However,
any little deviation in this surface feature or upper level
pattern could mean different cloud and precipitation coverage.|
Based on the current model trends, the location that has the
lowest probability of precipitation and cloud coverage is across
the far northern tier of ga.
The ridge aloft will quickly break down by Monday night Tuesday
morning as an upper trough dives down toward the eastern conus.
Impulses in the mid-levels will allow for better coverage of
showers thunderstorms Tuesday into Wednesday, especially across
Temperatures will be around normal through the period; albeit a
bit above normal Sunday with less clouds. Temperatures during the
eclipse (Monday) look to stay steady an hour before the maximum
obscurity (between 1pm-2pm), then drop a couple degrees up to 30
minutes after MAX obscurity (3pm). Temperatures are expected to
rebound quickly after the eclipse. The temperature drop will be
less for those under cloud cover precipitation. This drop in
temperature should not impact the high temperature expected during
expect aVFR forecast through the period with diurnal cumulus.
Have included only a vcsh in tafs for now... Thunderstorms should be
isolaterd to scattered and will have to watch and see which sites
may be affected since proabailities are low. Winds should remain
on the west side.

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.
