Precip has dissipated W the loss of heating. Forecast of persistence
looks the be the rule again tonight and Sunday. Ongoing fcst
looks fine... Just tweaked grids to match obs trends for the
update. 47

aviation [00z TAF issuance]...

showers and thunderstorms have dissipated withVFR conditions
across the region. Southerly flow will become southwesterly in the
morning around sunrise. Some patchy st possible near cll around
sunrise and can't rule out a brief stint of MVFR there. Otherwise
showers developing in the coastal waters after 09z and spreading
into the coastal areas around 12z. Redevelopment inland near the
seabreeze late morning and spreading into the metro terminals
19-22z time frame. Leaning toward the nmm solution and if short
term guidance trends in that scenario then will likely need tempo
in the mid afternoon hours as S W slides in from the northwest and
seabreeze collide if the mid level capping isn't too strong. 45

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.
