Discussion
A upper level low is in the northern gulf of mexico just southeast
of the texas coast, along with high pressure building north of
mississippi valley. Tropical moisture from the low has been
feeding showers and thunderstorms that have been for the most part
offshore with some bands extending inland. This convection should
die off tonight. A similar looking story is in store for tomorrow
as the moisture pushes even further inland. Heavy rainfall could
be possible with some of these storms near the coast. High
temperatures are a bit above normal due to subsidence from the
high pressure associated with the ridge further eastward.

Looking towards Thursday into Friday, a trough from the northwest
states will sweep the low hanging near texas along with it as well
as push the ridge eastward. It looks possible that a weak frontal
boundary could push into our area on Sunday.

Aviation
Vfr conditions can be expected through Tuesday evening. However,
scattered showers and a few thunderstorms will bring a threat near
kmsy, khum, knew and possibly through kbtr through 23z this
afternoon. Some storms may produce gusty, erratic surface winds
in excess of 25 to 30 knots. Look for most of this activity to
diminish late this afternoon and evening withVFR conditions
prevailing through the overnight hours tonight. 18

Marine
A tropical disturbance off the northern gulf of mexico will
produce some showers and thunderstorms as it moves westward.

Current small craft exercise caution criteria winds will slowly
decrease today into tonight and stay light until around late
Thursday into Friday where the next chance of a small craft
advisory is possible. -bl

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.
