Short term Tonight and Tuesday... Low clouds have been slow to
burn off over parts of NE fl and SE ga this afternoon. Weak high
pressure over the area with light winds may result in fog again
late tonight. An increase in high clouds overnight will likely
keep fog from becoming widespread so have patchy fog in forecast.

A dry cold front will move across the area on Tuesday bringing
slightly drier air to the area. Seasonal temperatures will
continue.

Tuesday night through Thursday night... Surface high pressure will
build to the north through the period. An inverted trough will
form off the east coast which will increase the pressure gradient
and winds on Thursday especially near the coast. A weak trough in
the zonal flow aloft will help produce scattered showers late
thurday and Thursday night mainly near the east coast with
isolated thunder possible over the coastal waters.

Long term Friday through Monday... A short wave and associated
surface low will move across the SE Friday night into early
Saturday. Scattered to numerous showers expected with a few
thunderstorms possible. Drier air will spread into the area by
Saturday afternoon as ridging moves into the area. Another fast
moving system will bring a chance of rain Sunday into early
Monday.

Aviation The stratus deck will continue to erode with all
terminals becomingVFR this afternoon. Potential for low
clouds and fog again tonight... However there will also
be an increase in high clouds which will tend to mitigate
the potential. For now... Have prevailing MVFR vsby at most
terminals (except ifr vsby at vqq) with scattered low decks
beginning after 05z-06z.

Marine A weak cold front will push across the waters on Tuesday
as high pressure builds northwest of the region through Wednesday.

Strengthening onshore winds will develop Thursday as high
pressure builds to the north. A surface low and cold front will
move across the southeast on Saturday. Advisory conditions
expected Thursday through Saturday.

Rip currents: moderate risk for northeast florida beaches due to
swells.

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.
