Update
Late evening surface analysis depicts high pressure (1022
millibars) centered along the mid-atlantic coast. The weak trough
that affected our region today has pivoted northward over the
south carolina coast. A surface trough over the central bahamas is
moving slowly northwestward. Aloft... Deep-layered ridging covers
the southeastern states. A tropical upper tropospheric trough
(tutt) was spinning westward into the western gulf of mexico. With
the trough that affected our region today shifting north of our
region, convection has quickly waned over our region, with fair
skies for all areas south of interstate 10 and thinning debris
clouds over southeast georgia. Goes-16 derived total precipitable
water imagery shows a much drier air mass advecting northward from
the florida peninsula ahead of the surface trough over the
bahamas, with pwats below 2 inches now moving into flagler and
marion counties. Temperatures and dewpoints were generally in the
mid to upper 70s as of 02z.

Clearing skies and drier mid-level air advecting into north
central and northeast florida from the south overnight should set
the stage for at least patchy fog formation during the predawn and
early morning hours at most inland locations. Temperatures will
not fall significantly from current conditions. The drier air mass
will preclude pops over north central and northeast florida on
Tuesday. The atlantic sea breeze will develop around noon at area
beaches and will move inland during the afternoon hours, keeping
highs in the upper 80s at the coast. Higher pwat values and weak
troughing will persist over southeast georgia, where scattered
afternoon is expected away from the coast during the afternoon
hours. Inland highs will reach the low to mid 90s, and dry air
mixing down to the surface over northeast and north central
florida during the afternoon hours will keep MAX heat index values
around 100. Higher humidity values over southeast georgia may push
heat index values to near 105 degrees before convection develops.

Mid-level temperatures will remain relatively mild again on
Tuesday, with locally heavy rainfall and frequent lightning
strikes being the primary threats over inland southeast georgia.

Aviation
Vfr conditions should prevail through at least 07z. MVFR
visibilities will be possible at the duval county terminals and
gnv through around 13z. Showers and thunderstorms should be
confined to inland southeast georgia on Tuesday afternoon, andVFR
conditions are expected to prevail at the regional terminals after
13z. The atlantic sea breeze will increase east-southeasterly
surface winds to 10-15 knots at sgj by 16z, crg by 17z, ssi and
jax by 18z.

Marine
High pressure centered off the southeast u.S. Coast will move
slowly eastward through midweek. An east-southeasterly ocean swell
will push into the offshore waters adjacent to northeast florida
on Tuesday, with combined seas increasing to 3-5 feet. Otherwise,
light onshore winds will prevail through Tuesday, with speeds
increasing to 10-15 knots near the coast during the afternoon as
the atlantic sea breeze moves inland. A low pressure trough
currently over the central bahamas will move slowly northwestward
and is expected to approach the southeast or central florida coast
on Wednesday or Wednesday evening. Some organization of this
feature is possible along the coast by Thursday. Meanwhile, a cold
front will push southward and will approach the southeast georgia
waters by late Thursday and Thursday night. Prevailing winds will
become offshore beginning on Tuesday night, but speeds will
remain below caution levels. The front will slowly push southward
into the northeast florida waters by Friday afternoon or evening.

Low pressure may develop along the frontal boundary late this
week, with northeasterly winds potentially strengthening by late
Friday.

Rip currents: an east-southeasterly ocean swell may keep a
moderate risk in place at the northeast florida beaches on
Tuesday, especially during the outgoing tide from the late morning
through early afternoon.

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.
