Update
Patchy fog inland will dissipate this morning. High pressure will
be northeast of the region today, leading to onshore flow. A weak
wave is expected to develop over the area this afternoon. The
combination of diurnal heating, sea breeze convergence and the
wave will lead to convective development today. The convection is
expected to initiate this morning near the coast, then move
further inland through the afternoon.

Aviation
Showers with embedded thunderstorms will develop near the coast
this morning, and move further inland during the afternoon. Brief
restrictions along with gusty winds will be possible in and near
storms.

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.
