Discussion
Wx map shows a broad sfc high over the gulf coast states, with high
pressure aloft dominating most of the central and southern plains.

Weak pressure gradient providing fairly light and variable winds
across the region. Radar showing isolated showers and thunderstorms
over the coastal waters and so far this afternoon south of i-10.

Further north, partly cloudy due to cumulus field over the region.

Temperatures are as expected in the lower to mid 90s. Dewpoints
mainly in the lower to mid 70s, yielding heat index values in the
103-107 range.

With high pressure aloft expected to stay over the region through
Friday, afternoon shower and thunderstorm chances expected to
remain 20-30% over SE texas & western louisiana. The western edge
of an approaching upper level low pressure moving across the
northern gulf will increase moisture and instability from the
east. This combined with afternoon temperatures in the mid 90s,
could ignite increased thunderstorms by late afternoon over ms se
la and move westward into central and south central louisiana by
late afternoon, thus the higher chances there.

This increased moisture and instability with the upper low is expected
over most of the area by the weekend, reflected in the increased
pops to 50% for both Saturday and Sunday afternoons. Gradual decrease
in shower and thunderstorm chances expected during the early part
of next week as the upper level low moves further westward into
texas and weakens. At this time, looks like the upper ridging will
resume its grip over the region with isolated to at best scattered
afternoon showers and thunderstorms.

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.
