Short term (tonight through Thursday)
Mid-level trough and shortwave rounding the base of it are moving
southward this afternoon, and will eventually wash out on Wednesday
as a high amplitude ridge over the gulf of mexico and lower
mississippi river valley shifts eastward over the southeast us.

Overall rain chances will decrease through the short term as
heights rise and for tomorrow, pops are limited mainly to just
north central florida on the tail end of what's left of a
prefrontal trough as it moves through the area. Pwats will remain
near 2 inches so heavy rainfall would likely be the primary
hazard from convection tomorrow, though a few stronger storms are
possible. By Thursday, this feature has departed, and with high
pressure wedging down the appalachians, onshore flow will develop
with breezy conditions near the coast and the atlantic seabreeze
moving well inland. With 500mb temperatures warming, and pwats
decreasing, only widely scattered storms are expected near and
west of the i-75 corridor.

Long term (Friday through Tuesday)
Forecast pwats are expected to drop dramatically for the weekend
as high pressure strengthens over the northeast. Heights will
start to fall some over florida as the upper level ridge to the
north remains steady and a weak shortwave moves across south
florida and into the gulf. High pressure will move into the
atlantic and winds will become more southeasterly by Sunday,
increasing pwats and thunderstorm chances for most of the area.

This trend will continue into the first part of next week as
onshore southeasterly flow keeps moisture around and a more
dominant atlantic seabreeze moving inland each day.

Aviation
Showers and thunderstorms have been slow to develop so far this
afternoon with only a few isolated storms across NE florida so far
today. This will change during the late afternoon and early
evening as heating continues and surface boundaries like the sea-
breeze and thunderstorm outflows collide. Did add a tempo group
for jax and vqq as confidence is increasing that a concentrated
group of thunderstorms will move from north to south from georgia
into north florida during the evening hours. Remnant cloud debris
will fade throughout the overnight as winds calm.

Marine
A surface trough will move into the coastal waters and dissipate
over the northeast florida waters tomorrow. Southerly winds will
increase briefly this evening, before becoming more northerly
tomorrow as high pressure moves in from the north. Winds will
quickly become easterly for the remainder of the week and into the
weekend as high pressure weaken and settles over the southeastern
states this weekend.

Rip currents: moderate risk.

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.
