Aviation
With little change in the overall pattern in the next 24 hours, a
forecast of persistence looks to be the way to go.VFR conditions
mostly persisting outside of any iso sct aftn storms - mainly
closer to the coast. A few patches of MVFR CIGS remain a slight
possibility 4-10am, otherwise another repeat for tue. 47

Prev discussion issued 1109 am cdt Mon aug 21 2017
drier air moving into the region from the gulf this morning and
this is likely what is keeping the radar mainly quiet. The upper
low over the gulf is forecast to continue its slow westward trek
towards the local waters through early tomorrow. Shower and
thunderstorm coverage should increase over the coming hours... If
not from lift along this low's far western reaches... Along the sea
breeze boundary. Decent cumulus field quickly sprouted up in the
last hour so anticipating that many may find it challenging to
find a nice... Clear view of this afternoon's partial solar
eclipse. Optimal viewing of the eclipse is in a couple of
hours... Or around 1:15 pm cdt. 31

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.
