Near term through Tuesday
Scattered to numerous showers with embedded thunderstorms this
afternoon in response to the combination of diurnal heating,
boundary interactions and a weak trough. Much of the convection will
dissipate by sunset, with a few showers lingering till around
midnight. Clouds will diminish overnight, with patchy fog developing
well inland. High pressure ridge that is to the northeast today,
will be to the east of NE fl on Tuesday. The ridging is expected to
provide subsidence across NE fl limiting convective potential, with
chances for convection for SE ga. Temperatures will trend above
normal this period.

Short term Tuesday night-Thursday
Weak trof of surface low pressure will extend from the carolinas
and south ga southward through the fl peninsula during this
period. While weak high pressure ridge will exist aloft overhead.

Drier airmass in place Tuesday night will lead to fairly quiet
conditions with fair skies and muggy conditions and temps in the
mid upper 70s. Airmass will slowly moisten through the period with
near climo scattered diurnal showers storms on Wednesday building
to scattered to numerous showers storms by Thursday with best
chances across SE ga. Very weak steering motion either light and
variable or out of the W SW will promote locally heavy rainfall as
the storm motion will remain around 10 mph or less and mid level
temps remain fairly warm around -5c -6c so severe storms are not
expected but a few strong storms are possible with gusty winds and
frequent lightning as atlc gulf coast sea breeze fronts move
slowly inland each day. Warmer than normal MAX temps are expected
with highs in the lower middle 90s inland each day and near 90 at
the coast. Heat indices will top out near 105 degrees each
afternoon prior to the start of convection.

Long term Friday-Monday
Long-range models still struggling with handling of slow moving
disturbance over the SE bahamas that will track slowly NW and
possibly develop into a weak TC by late in the week into the
weekend off the florida east coast and track NE of the region by
by early next week. At this time it appears as though NE fl SE ga
will be on the north or northwest side of this circulation with
surface northeast flow developing off the atlantic and while this
will keep abundant moisture over the region with at least
scattered to numerous showers and storms mainly during the
afternoon and evening hours and mainly along the coast. Higher
confidence that daytime maximum temps will come down from the
lower 90s on Friday to the mid upper 80s over the weekend into
early next week. Much lower confidence in the organization of any
heavy rainfall bands that may impact the region especially along
the coast but it remains a possibility and will need to be
monitored, with higher chances if a more significant TC develops.

Aviation
Convection is expected to dissipate across area TAF sites by sunset,
with conditions trending towardVFR this evening. Inland fog
formation will be possible tonight, with restrictions possible at
kgnv. Convection will be possible Tuesday afternoon, mainly over
se ga, which could affect kssi later in the day.

Marine
High pressure will be to the northeast tonight, and to the east
Tuesday and Wednesday. A tropical wave may move to the east of
area waters Wednesday. High pressure will build to the southeast
Thursday, with a cold front reaching the SE ga waters. This front
will sink further south across area waters Friday into Saturday.

Rip currents: low to moderate risk in the weak onshore flow with
daily sea breezes.

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.
