Discussion
Late afternoon thunderstorms developed along the sea breeze
boundary. Storms are mainly stationary, but drifting to the
west. The stalled boundary will start to lift back to the
north as high pressure ridges over the boundary tonight,
then another low pressure system will push into the region
for later Sunday through Monday. Have adjusted pops a bit
for the overnight period, but everything else is on track,
and will update for these changes.

Aviation
Showers storms will drift west and dissipate over the next
hour. Winds will then become more easterly with some MVFR
ceilings developing around 08z. Winds increase and turn to
the SE after sunrise with the ceilings lifting back toVFR,
then a sea breeze turns winds onshore in the later
afternoon.

Marine
Evening sea breeze thunderstorms will push offshore and
dissipate. The scec will continue over the northern offshore
coastal waters. Weak ridging will build into the waters
tonight, then a low pressure system moves in for later
Sunday through Monday bringing showers and thunderstorms
across the area. Current forecast is on track and have
little change for the update.

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.
