Aviation [through 06z Saturday]
Vfr conditions expected through the period outside of any tsra. Ts
coverage is expected to be iso to sct once again this afternoon,
keeping confidence limited in any activity directly affecting any
terminals. Vld, tlh and ecp have the highest chances to observe ts
after 18z. Westerly winds generally below 10 kts at all sites
through the period.

Prev discussion [904 pm edt]
Near term [through tonight]
Deep layer ridging will remain in place across our area through the
rest of today and tonight. Ample moisture remains present across our
area with dewpoints in the mid 70s and pwat values around 2", and as
a result scattered showers and a few thunderstorms have developed
early this afternoon. Expect best chances to remain confined to
northern fl as the sea breeze remains pinned relatively close to the
gulf coast due to light northwesterly flow. Only isolated showers
and thunderstorms are expected across SE alabama and SW georgia,
where little to no forcing will be present. Heat indices will remain
in the low-mid 100s across much of our area this afternoon through
the early evening with temperatures in the lower-mid 90s and
dewpoints in the 70s. Lows will be in the mid-upper 70s overnight
across most of our area, and near 80 along the coast.

Short term [Friday through Saturday night]
The local area will be sandwiched between a northern stream trough
moving through the mississippi and ohio valleys and a tutt moving
through the eastern gulf. At the surface, a frontal boundary
associated with the northern stream trough will slide into the
southeast and eventually bisect the tri-state region from
northeast to southwest by Saturday. Rain chances will be higher
than the past couple of days, with storms forced along the front
and along a more active land seabreeze where the tutt can assist
with synoptic lift. Highs will be in the lower to middle 90s with
heat indices between 100-105.

Long term [Sunday through Thursday]
Upper level ridging will dominate through Tuesday, with the
surface front gradually dying in place over the region through
Monday. Thus, with plentiful moisture and a surface focus, expect
near to above average pops to start the week. Convection may not
be extremely robust due to some dry air above 700mb, but certainly
shower activity at a minimum should be expected. A shortwave
moving through the ohio valley and mid-atlantic will deepen the
eastern CONUS trough by midweek, keeping rain chances elevated to
end the period. The tropics remain active and uncertain, but the
potential exists for at least some tropical moisture to spread
into the gulf early next week. Pay close attention to the tropical
forecast over the coming days.

Marine
Light winds and low seas will prevail for the next several days.

The best chance for rain will be between midnight and noon.

Fire weather
Red flag conditions are not expected for the next several days.

Hydrology
Showers and storms are expected each day. Although minor flooding
could occur in urban and poor drainage areas, widespread flooding
is not expected.

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.
