Aviation [06z TAF issuance]
Band of MVFR ceilings 1500-2000ft spreading inland and expect
periods ofVFR MVFR conditions through sunrise for mainly
cxo uts cll. High-res guidance has been doing a good job of
capturing the lower ceilings. Showers should develop over the
coastal waters around 09z and then move inland 11-15z but should
be mainly over the southern terminals. Guidance has been trending
much drier than yesterdays runs and have kept with the vcsh
wording in the TAF for the 15-20z time frame. Can't rule out
isolated thunderstorms for the hou area southward. Skies should
again clear out quickly Monday evening.

Discussion
Per WV imagery, we are seeing a good bit of drier air move into
cwa from the NW at this time. This looks to be helping with the
decreased activity and clearing skies at present. Did make some
tweaks to the near-term grids to account for these trends. 41

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.
