Discussion
High pressure will be ridging across the area for the next couple
of days, with the ridge axis across the north or just north of
the area through much of the period. This will keep more of a S se
flow across the north, SE central, and E SE south, with afternoon
sea breezes turning winds onshore in the afternoon and light
variable winds overnight. Scattered afternoon and evening showers
and thunderstorms will also be possible. Highs will reach
generally into the lower 90s, with afternoon heat index values of
100-105. Lows tonight in the mid 70s north and inland to around
80 at the coast. The current forecast is on track with all of this
and have no updates planned.

Aviation
Light E SE winds increasing in speed through the late morning,
then turning to the SW in the afternoon as the sea breeze develops
with a few showers storms possible. Then late afternoon continuing
to turn to the W NW around 8kts as storms continue to be a
possibility. Then winds becoming light and variable after 02z with
convection dissipating for the overnight hours.

Marine
Light generally SE winds through the weekend with afternoon sea
breezes turning winds to the west each day. Scattered showers and
thunderstorms will be possible each day as well. Current forecast
is on track and have little change for the update.

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.
