Discussion
Weak ridging at the surface and aloft will continue across
the area through early Friday. An inverted trough will then
move over the area later Friday through Saturday, and the
deeper moisture with it moving over the state through
Sunday. Scattered showers and thunderstorms will develop and
move inland through the afternoon and early evening.

Temperatures on track to reach into the lower to mid 90s. No
updates planned as current forecast on track.

Aviation
A few morning showers possible near the coastal terminals
this morning, then becoming thunderstorms and increasing in
coverage across the area through the late morning and
afternoon as winds increase from the W nw. Convection then
ending and winds becoming light and variable after 01z.

Marine
Weak pressures in place will allow for diurnal forcing to
turn the winds to the W NW especially along the coast during
the afternoon hours. Winds and seas will remain light with
scattered showers and thunderstorms possible over the
waters. Current forecast is on track with all of that so no
updates planned.

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.
