Discussion
The moisture gradient leftover from the old frontal boundary
continued to be evident today. Most of the showers and thunderstorms
today have been confined to about the southwest half of the forecast
area where a mix of 12z observed soundings, model soundings and the
goes tpw product have indicated precipitable water (pw) values
rising back to near 2 inches. The forecast area will remain in area
on the eastern periphery of a large, hot continental high over
northern mexico into the southern to central plains. This will place
the central gulf coast region in more of a weakness trough to weak
north to northeast flow in the mid levels through the early part of
next week. This should result in temperatures trending down a bit
closer to normal and precipitation probabilities rising to above
normal values over the next several days into the middle of next
week. There are no strong signals for either severe thunderstorm
potential or excessive rainfall, however there will likely be some
localized areas that experience some higher rainfall totals from
slow moving thunderstorms each day which may result in ponding of
water or minor flooding. The upper level features are expected to
continue to retrograde west during the mid to latter portion of
next week which will maintain a weakness trough aloft over or near
the forecast area. This will maintain generally likely rain
chances during daytime hours through the 7 day forecast period.

Aviation
Vfr conditions prevail at all area airports and are expected to
persist through the overnight hours today. Some vicinity showers and
thunderstorms are possible at some area airports the remainder of
this afternoon. These showers and storms could cause temporarily
lower ceilings and visibilities where they occur. In addition, these
storms could cause brief wind shifts greater than 30 degrees when
they occur. Msw

Marine
A ridge of high pressure centered over florida today will expand
west across the gulf of mexico through the early to mid part of next
week. Winds will be mostly south to west around 10 knots or less,
but will occasionally be in 10 to 15 knots range. 22 td

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.
