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 Wednesday ...
surface high pressure over the western atlantic and eastern
seaboard is causing low level moisture clouds to increase
across the forecast area. This low level flow will also aid
the potential for enough upward vertical motion to allow for
mainly small chances for light rain across much of the forecast
area favoring only slightly the far NE mountains and the southern
portion of central ga.
A weak cold front is forecast to move across the area tonight and
the first portion of Wednesday. This will continue mainly small
chances for light rain overnight favoring east and central ga and
portions of central ga on Wednesday.
The increase of low level moisture today will allow for areas
of fog tonight and will need to monitor for dense fog potential.
Forecast high temperatures are running within 1-3 degrees of
normal today and Wednesday. Forecast low temperatures are running
4-8 degrees above normal tonight.
Overall confidence is low to medium.
Long term Wednesday night through Monday
Models in the long term continue to vary from run to run on the
evolution of thanksgiving day system but fortunately have more
agreement among themselves than at any point in the last several
days. Both indicate a developing area of low pressure by the start
of the extended period over the gulf of mexico. The GFS is
slightly stronger and further north with the system than the ecmwf
but overall deep moisture profiles are very similar with this run.
By Wed night, precipitable water values in excess of 1.4 inches
are moving into portions of central ga in increasing favorable
isentropic upglide environment.
Given the good model agreement, will go with likely pops for the
extreme southern tier but give a sharp gradient to pops with less
than 20 for the atlanta metro. It should be noted though that it
would take very little in surface low displacement northward to
go from nothing to near washout for areas along i20 on|
Model differences continue through Friday with GFS faster with the
progression of low and ECMWF remaining displaced southward
although both models show a florida peninsula track. This should
allow drier air to be drawn in on the north side of the system
Friday into the weekend effectively ending rain chances. Fairly
benign pattern thereafter with just a dry front to contend with
before high pressure builds in for the remainder of the period.
Aviation 06z update... Increasing potential for MVFR and
possibly ifr ceilings this morning along with patchy to areas of
light rain and drizzle during the day. Confidence for ceiling
heights and rain drizzle chances are low and will need to be
monitored. Some improvement during the day to high MVFR toVFR
ceilings. Surface winds light and variable or light se-ne.
Potential for low clouds and fog tonight.
Atl confidence... 00z update...
high confidence for winds today.
Low to medium confidence for all other elements.

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.
