discussion... See aviation section for 00z tafs.

Aviation... MVFR ceilings over portions of the coastal bend at
this time is expected to become prevalent early this evening.

Expect MVFR ceilings will reach inland areas from vct to lrd
between 08-09z. MVFR ceilings will remain over south texas through
the rest of the night into Saturday. Southerly low level flow of
30 knots will increase the low level moisture by Saturday morning.

Isolated showers in the morning is expected to increase in
coverage to scattered over the coastal plains in the afternoon.

Model forecast soundings indicate the mid level inversion will
remain strong over the region with a very limited threat for deep
convection. Tempo or prob30 groups for showers over the coastal
plains in the afternoon with better chances in the vct area.

Southeast winds will be gusty along the coast as a surface low
moves east across north central texas in the afternoon.

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.
