What's New / NOTES
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.

GMZ400 Synopsis For Lower Atchafalaya River La To High Island Tx Out 60 Nm Including Sabine And Calcasieu Lakes And Vermilion Bay 900 Pm Cst Sat Feb 24 2018
Synopsis.. Gusty south winds will gradually decrease this evening as a cold front begins to push into the area this evening. With winds relaxing, a brief period of patchy sea fog is possible after midnight tonight into Sunday morning for the nearshore coastal waters west of cameron. The cold front is expected to stall near or just offshore the coastline Sunday morning, and remain nearly stationary through the day Sunday. Showers and Thunderstorms will accompany the front tonight and continue through the day Sunday before coming to an end Monday as the front is finally driven out of the area. A brief period of light to modest offshore flow will prevail Monday with winds turning east and then southeast on Tuesday. South winds will strengthen a bit Wednesday ahead of another front forecast to cross the coastal waters Wednesday night, with a light to modest offshore flow behind this front closing out the week.

Discussion
Wx map shows cold front across NE tx approaching lufkin to NW la
between shreveport and natchitoches through SW ar. Showers and
isolated thunderstorms beginning to increase along and ahead of
the front, which was expected. SPC still has area outlined in
marginal risk for the possibility of the stronger thunderstorms
reaching severe limits, with damaging winds the primary severe
weather threat. Otherwise, precipitation chances will continue to
increase as the front sags further south, and likely stall along
the i-10 corridor of SE tx SW la by daybreak. Thus, current
forecast shows this with no changes made at this time.

aviation... Generally MVFR ceilings are occurring across the
region, however ceilings will lower and become ifr this evening.

Rain and storms are also expected overnight reducing vis. High
rain chances will linger through the rest of the period.

breezy and warm afternoon across the forecast area between
subtropical ridge to the east and sfc low trailing cdfnt to the
nw. Winds are expected to subside by early evening, so the wind
advisory was left as is to expire at 00z. Isolated to scattered
showers along with a prefrontal band of showers noted on radar
imagery well ahead of the actual surface boundary, which stretched
from near texarkana to waco based on sfc obs radar data. Lead
upper trof currently translating through the plains based on water
vapor imagery, with an upstream trof digging through the pac nw.

Lead trof is progged to pivot E NE toward the upper midwest great
lakes tonight, resulting in a frontal boundary that is
increasingly stretched out oriented parallel to the mean flow.

The front is expected to limp through the forecast area tonight,
but stall somewhere near the coast by Sunday morning. Despite the
lead upper trof pulling away, a deep moisture pool along with
more favorable jet positioning aloft will yield increasing showers
and thunderstorms as the front progresses through the area. The
risk of severe thunderstorms is marginal, and primarily in the
form of strong damaging winds. Overall rainfall amounts are
expected to be on the light side (generally one half of an inch
or less), but given the high moisture content (pwat near 1.8
inches) locally heavy rainfall is not out of the question.

Behind the front, relatively cooler air will settle southward,
though temperatures tonight will still be closer to normal highs
than lows, especially along S of i-10. Where the front eventually
settles is still not altogether clear, though a best guess is
that it makes it into at least the nearshore coastal waters. A
relative lull in rainfall intensity and or coverage may
materialize for a time Sunday morning, but the approach of the
aforementioned upstream upper trough and associated
intensification of downstream low mid level kinematic fields is
expected to yield an increase in coverage and intensity Sunday
afternoon and night. Initially, this should occur over E tx with
subsequent ewd progression across la. This could be problematic
for parts of interior E tx into central la that were soaked just a
few days ago, though the generally progged progressive nature
appears to preclude a sustained widespread risk of heavy rainfall.

Rains are expected to be winding down by Monday morning, as the
sfc front is driven S and E of the area and drier air pushes into
the region.

For the medium to extended range, the break in rain will be short
lived as the front and its associated moisture pool retreats
north on tue, bringing scattered showers and thunderstorms along
with warmer temperatures back into the area. Rains shift north of
the area on wed, but return Wed night as another front pushes
through the region. Dry with mild afternoons and cool nights closes
out 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.
