the majority of convection this morning has remained to the west
of the area, but isolated to scattered activity is expected to
develop and move inland across southeast texas through the
afternoon. Convection will be more isolated across southwest
louisiana. Updated pops to reflect this thinking. The rest of the

satellite and surface observations indicate that ground fog has
developed again this morning across interior SE texas and
louisiana. This will result in MVFR visibility restrictions for
kaex through 9 am with tempo reductions to ifr lifr, mainly over
the next one to two hours.

Once the fog dissipates,VFR conditions are expected to prevail
through the day with light winds. Isolated to scattered showers
and thunderstorms will be possible from mid morning through the
afternoon. For now, vcsh vcts was only included for SE texas where
there currently appears to the greatest chance for any convection.

Any shower or thunderstorms activity should end around sunset.

Prev discussion... Issued 300 am cdt Thu sep 21 2017
discussion...

wx map shows weak high pressure over the southeast u.S. With light
south to southeast flow over the region. Further inland, patchy
fog noted across our region once again. Might see intermittent
patchy dense fog towards daybreak, but not expecting widespread
dense fog at this time.

With above normal temperatures and dewpoints, summertime
conditions expected to prevail for the next week. Isolated
afternoon showers and thunderstorms will continue each afternoon
through Friday with little appreciable forcing expect afternoon
heating. Increased moisture from the eastern gulf coupled with an
deepening upper level low over the southeast u.S. To bring
increased chances of showers and thunderstorms for the weekend
into next Monday. Temperatures expected to stay slightly above
normal through the period.

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.
