Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

Update for aviation
Prev discussion... Issued 713 pm edt Sun mar 24 2019
a band of scattered light showers sprinkles has developed over
northern al. Hi-res has this moving into extreme north ga through
this evening. With dry air in place, not quite sure enough
moisture will make it to the ground, but there is enough of a risk
to add a 20 pop across extreme north ga through 06z. No other
Significant large hail event possible Monday late afternoon and
short term tonight through Monday night ...
main concern in short term period is threat for strong severe
convection Monday afternoon and early evening.
Latest guidance still indicate that strong to severe hail event
on tap for Monday late afternoon and evening. As mentioned
previously, steep lapse rates with MLCAPE approaching 1000 j kg
and strong deep vertical wind shear all coming together, best
combination of shear and instability over westcentral ga and atl
metro areas. Hail up to or even larger than 2 inches expected.
Can't rule out some brief quasi-linear storms and multicells, but
expecting to see mostly cells and supercells with weak rotation.
A little concerned that 12z href (high res ensemble forecast from
spc) shows some decent updraft helicity potential in and near atl
metro 21z-00z. Can't rule out brief weak tornado in spite of very
weak low level vertical wind shear. Storms should move out and or
dissipate by 10pm.
Precip amounts coming in a bit higher than prev forecasts, but
total amounts still less than 1 in. No issues with flooding
expected as soil conditions have dried considerably in the last 2
weeks. Could see significant rises on creeks streams in fast-
response urban basins in atl metro, especially if storm becomes
slow moving supercell and tracks over a favorably-oriented shaped
Otherwise, expect moderating diurnal ranges for temps with warmer min
temps and a little cooler MAX temps due to increased low level
moisture and clouds precip. Fire danger will be much reduced in
long term Tuesday through Sunday ...
as the long term portion begins, will see a secondary closed upper|
low drop through alabama and ga. Although instability will be very
limited with this system, it has a very cold core with -24c at
500mb. Would not be surprised at all to see some small
hail graupel emerge from this despite the lack of thunder. Will
increase pops slightly for Tue afternoon, but otherwise forecast
for this part of the extended looks on track.
Clearing conditions with no rain expected until weeks end and into
the weekend. Will await the new ECMWF but as of now significant
differences exist with the GFS diving upper low into the 4 corners
and keeping there while the ECMWF is much more progressive in
bringing a front through the area. Think low to mid range pops
that the grids show currently is on target until models resolve
No other changes to the extended made other than loading in some
of the new guidance for temps and dewpts which are not off that
far from the previous versions.
for the most part,VFR through the forecast with loweringVFR ceilings
and potential for MVFR conditions associated with heavier showers
and thunderstorms this afternoon into the evening. Surface winds
staring calm or light ssw then wsw around 10 kts and becoming wnw
late today and tonight.
Atl confidence... 06z update...
high confidence for ceilings to start then low to medium
confidence for ceilings and thunderstorms after 13z.
High confidence for winds.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
