Discussion Scattered convection continues to develop along
coastal convergence zone with strongest moisture flux convergence
shown by msas near the mid-coast region. Raised pops slightly
there for the remainder of the night. Also raised pops for western
webb county where storms continue to drift northwest. See aviation
section for 06z tafs.

Aviation Goes image of precipitable water shows very deep
moisture in place across south texas with pwat values near or
slightly above 2 inches. Scattered convection persists near
coastal convergence zone early this morning. Expect this activity
will affect vct area over the next 2-4 hours with a little less of
a chance for showers at the other TAF sites. MVFR ceilings will
become prevalent over region by 09z. Expect scattered convection
will develop again along the coast after sunrise and slowly drift
inland along this convergence axis through the day. Will keep threat
of tsra MVFR vsbys and ceilings for the coastal TAF sites through
the day with a chance of convection reaching lrd this afternoon.

Vfr conditions expected by late afternoon as the convective
activity diminishes. May see MVFR ceilings reform along the coast
late Sunday evening along with scattered showers aft 03z.

Crp watches warnings advisories
Tx... Coastal flood advisory until noon cdt today for the following
zones: kleberg... Nueces.

Gm... None.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
