Discussion
Forecast of persistence looks tough to beat thru the holiday
weekend. Pattern will generally consist of a southeastern u.S.

Ridge and a western trof. We'll be situated closer to the
periphery of the ridge and its associated subsidence should limit
overall chances of precipitation (though can't totally rule out
some streamer type shra from time to time). So, in general, look
for late night and morning cloudiness followed by pcldy days with
lows in the 70s and highs around 90.

Early next week, a shortwave will drop into the base of the trof
and eject northeast from the four corners area toward the great
lakes Tue and wed. This should somewhat flatten the ridge as this
occurs and send a frontal boundary into texas during the midweek
time period. This front should eventually lose its southward support
and stall somewhere near or north of southeast texas. It'll be
the next focus for decent shra TSTM chances, but until confidence
increases as to where the boundary ends up we'll be keeping pops
topped out around 30% for northern zones for the time being. 47

Marine
The strong onshore winds of the last few days will continue to de-
crease through the weekend. Will maintain the small craft advisory
for the offshore waters through today, as seas slowly subside. The
nearshore waters and matagorda bay will see caution conditions for
winds today. Otherwise, the forecast for the weekend should remain
similar to that of today - generally moderate onshore winds across
the bays nearshore waters and slightly stronger winds over the off
shore waters. However, despite the decreased SE winds, the coastal
flood advisory will likely continue as the onshore fetch persists.

Minor coastal flooding with wave run-up remain possible (especial-
ly during high tides) for gulf facing locations. Additionally, the
surf will remain elevated to rough at times... With strong rip cur-
rents a concern given the increase in beach goers for this holiday
weekend. 41

Aviation
Brief MVFR CIGS are still expected this morning... With sct bknVFR
decks expected this afternoon. We should see a return of MVFR cigs
and iso weak WAA showers across SE tx this evening overnight given
the persistent onshore flow. Not a lot of changes are expected un-
til the start of next week. 41

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

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.
