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.

area forecast discussion
national weather service new orleans la
412 am cdt Fri jun 22 2018

Short term
A very typical june july pattern setting up across the area. Warm
and muggy with a few sh TS around although we will see less over
the next several days than we have been. Sea breeze will also be
a feature we should see almost daily. Heat index readings will
also begin to be watched but so far the highest seen over the next
few days is around 106f.

There is a hint of deeper moisture moving in from the east by
next weekend which could boost our rain chances and it will likely
be needed by then.

Aviation
Expect MVFR toVFR conditions to prevail. Some light fog and low
cigs are possible during the morning hours at a few sites. These
places will see the MVFR conditions through the morning hours before
conditions improve to mostlyVFR across the entire area. There is an
outside shot of an isolated shower or storm this afternoon across
the far northern portions of the forecast area. Confidence is not
high enough to include in TAF at this time.

Marine
Onshore flow continues for today and lasting through the weekend.

High pressure still remains centered just off to the east of the
area allowing for the continued onshore flow. There could be some
tightening of the gradient tonight. This could result in winds
rising into the 15 to 20 knot range and seas climbing into the 3 to
5 feet range. This will be sort lived as the gradient relaxes
Saturday. Going into next week the high settles more over our
waters and conditions lighten up. The wind field will turn much
lighter and more variable. Seas should also decrease to 2 feet or
less due to these lighter winds.

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.
