Update
Forecast is in good shape this morning and no changes were made.

Winds will increase throughout the day as the low that is expected
to bring showers and thunderstorms tomorrow deepens and pushes
east out of western texas. Otherwise, partly cloudy skies and warm
temperatures will prevail today.

generally benign weather on tap for today as ridging between a
departing shortwave trof over the oh river valley and a digging
upstream trof west of the four corners slides overhead. Expect a
warm and humid afternoon underneath a fair amount of cloud cover,
with south winds increasing and becoming a bit breezy over
coastal SE tx/sw la. Another warm and muggy night tonight with
winds remaining elevated, especially along the coast and over the
wrn zones as a 30-40kt LLJ begins to overspread the area with the
approach of the upstream trof.

Wed is expected to start out relatively quietly owing to
considerable cinh depicted in area fcst soundings. This is
expected to begin changing by afternoon, however, as more
favorable lapse rates begin to overspread the area along with
falling heights and a split jet structure as the upper trof enters
the tx panhandle. Tstms are forecast to develop/ over E tx by
late afternoon, then subsequently spread/develop E of the sabine
river during the evening. Progged kinematic/thermodynamic
parameters support a severe weather risk, with all modes possible.

Tstms will continue to slowly spread/develop east through the
overnight hours and into Thu morning, with activity expected to
push east of the area during the afternoon with the passage of a
weak cdfnt. Have continued with a mention of svr tstms in the
forecast for the Wed afternoon through Thu afternoon period.

Dry weather is expected in the wake of the frontal passage Fri and
sat, with rain chances returning Sat night with the approach of
another upper level trof. Global models continue to be divergent
with their handling of this feature, though at this time a slower
and less progressive solution is favored, keeping good rain
chances in the forecast Sunday and Monday.

light to modest south winds are forecast to begin strengthening
today as a low pressure system emerges east of the rockies. Have
headlined scec for the gulf waters within 20 nm west of cameron
and all of the gulf waters beyond 20 nm for late this afternoon,
then switched to a scy for these areas this evening. Scec for the
remaining gulf waters east of cameron this evening. Brisk south
winds will continue Wed as this feature tracks eastward across the
plains, subsequently pulling a frontal boundary through the
coastal waters Thu afternoon/evening. Additional hazard
headlines/products may be needed for wed. A brief period of
offshore flow will follow the frontal passage, with south winds
returning by fri.

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.
