The trough will weaken and eventually dissipate later tonight with a light to moderate onshore flow prevailing for the next several days. Deepening tropical moisture and a series of upper level disturbances will bring increased chances of showers and Thunderstorms during the early part of the week. Winds and seas will be higher in and near these storms.

Aviation [06z TAF issuance]
Overall think guidance and last set of tafs are on track with
mainlyVFR MVFR ceilings the rest of the night and into the
morning. Still a small chance at some ifr so will leave mention of
a sct cloud deck around 800ft for most tafs. Ceilings should be
clearing out through the afternoon as an upper level trough axis
finally exits the region. Until the trough axis moves through,
cloud cover will remain which makes it challenging to time when
ceilings improve.

Prev discussion issued 1027 pm cdt Sun sep 23 2018
Updated the forecast to include some light showers and drizzle
across the northern parts of the area tonight. Although the radar
appears to be overshooting any precip, a few sites across the
brazos valley have been intermittently reporting some light rain
and or drizzle with the large stratus deck overhead. Otherwise,
the previous forecast appears to be on track. 11

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.
