Short term (tonight-Tuesday)
Surface high pressure centered just offshore of new england
is ridging down across the area, with ridging aloft centered
just to the east of the state. This will keep E SE flow in
place across the area with moderate winds strong enough to
prevent sea breeze development Tuesday afternoon. A little
pocket of moisture will lift over the area in the flow
tonight into Tuesday, and may have a stray shower or two
Tuesday afternoon, but left chances at a silent 10 percent.

Patchy fog will again be possible mainly across the nature
coast overnight. Temperatures will continue to be warm,
with lows in the 60s and highs in the 80s.

Long term (Tuesday night-Monday)
A series of mid upper level shortwaves will continue to move
across the central and eastern u.S. Well north of the
region with ridging holding over the florida peninsula.

Meanwhile surface high pressure will extend west from the
atlantic ocean back across the florida peninsula into the
weekend before a cold front moves into the southeast u.S.

And eventually washes out across north florida early next
week. For our area this pattern will mean a continuation of
the warm temperatures, more typical of late april early may,
with a few record highs possible. It will remain mainly
dry, but late in the week through the weekend there could be
just enough moisture when combined with daytime heating and
the sea breezes to pop a couple of showers here and there.

Overall though it will remain partly to mostly sunny, warm,
and dry with the only potential problem being some late
night and early morning low clouds and fog.

Aviation
Vfr conditions mainly expected through the period. Some
light patchy fog may develop toward morning at klal, but
otherwise not expecting any visibility issues. Winds will be
from the E SE lightening to around 6 knots overnight, then
increasing to 10-12kts with some gustiness for Tuesday
afternoon.

Marine
High pressure will ridge across the waters through the
period, keeping an E SE flow across the waters with a weak
sea breeze possible near the coast during the second half of
the week. Some patchy fog will be possible over the northern
coastal waters overnight. No headlines expected through the
period.

Fire weather
No concerns.

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.
