Discussion
For the 17 12z TAF issuance.

Aviation
For the next couple of hours or until about 17 14z, there is a
slight chance that some patchy fog will affect the terminals with
MVFR visibilities. Otherwise, surface high over the gulf south
will continue to weaken and move off to the east. Therefore, more
of a southerly flow is expected over the forecast area. However,
return flow moisture will be meager at first, so a majority of the
clouds today will be in the upper levels. Therefore,VFR
conditions are expected to prevail during the day.

discussion...

the 1024 hpa high pressure currently centered over the
southeastern united states will slowly shift eastward over the
next 24 hours. This will result in increased onshore flow and a
slight increase in deep layer moisture across the region.

A weakening short wave is forecast to drop southeastward from the
pacific northwest on Sunday which will help support the
development of a weak area of surface low pressure over north-
central texas. This system will result in chances for showers
beginning in southeast texas Sunday afternoon and continuing
across the entire CWA from late Sunday night through Tuesday.

The next upper level shortwave trough is forecast to progress
across the southern plains into the lower mississippi river valley
on Wednesday and Thursday. The associated surface low pressure
will result in another period of increased showers and possibly a
few thunderstorms on Wednesday and Thursday.

Beyond Thursday, model guidance begins to diverge with a variety
of different solutions for the amplitude and timing of the next
two upper level troughs which could affect the weather across the
area. For now, it appears late Thursday into the day on Friday
conditions will be dry across the region. Then there will be the
possibility of another period of showers and thunderstorms late
next weekend. However, the confidence in the forecast beyond
Thursday is only average at best. Therefore, further refinements
to next weekend's forecast will continue to be made through this
weekend into next week.

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.
