Marine Weather and Tides
Bay St. Louis, MS

Version 3.4
What's New / NOTES
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.

345 am cdt Wed jun 20 2018

Short term
Satellite imagery shows an upper ridge spreading westward across the
eastern gulf of mexico. Although subsidence will moving into the cwa
from the gulf, still will have enough moisture in place and daytime
heating to produce a few showers and thunderstorms. Expect more
farther inland and little to none in the coastal areas.

An upper level trough will move across the central plains today and
into the mid upper mississippi valley Thursday. This will cause the
ridge over the gulf to retreat slightly. A gradient in convective
coverage will likely exist with highest pops in northern forecast
zones and lowest along the coastline. Have increased pops to near
60% in SW mississippi with 30% or less from new orleans southward.

Long term
The aforementioned upper low will lift northeast ending this week,
thus allowing the ridge over the gulf to spread north over the
region this weekend. Subsequently, rain chances will drop quite a
bit and temps should be on the rise. Kept previous pops of 20% and
slightly increased high temps into the lower 90s.

Aviation
Some tempo MVFR ceilings possible this and Thursday morning but all
sites should be inVFR conditions for most of this TAF cycle. There
will still be a lower chance of a TS today but chances are too low
to show in any one TAF set.

Marine
Pressure gradient continues to weaken further and winds are
responding as they drop to around 10 knots for most areas with a few
still registering from 10-15kt. Seas will also stay at 3 feet or
less through the remainder of the week.

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.
