Additional flooding rainfall fading across NE fl...

Rainfall potential increases across SE ga Sunday...

Update
Stratiform rainfall was fading across NE fl this evening on the
wsw side of a weakening mesolow that was over duval county this
hour, drifting eastward. Low pressure centers were forming wsw of
apalachicola and offshore of the sc coast, with weak low level
ridging strengthening over north florida from the south. Although
deep moisture will continue over the area tonight, forcing
mechanisms to generate rainfall will be weakening. The strength
and depth of low-mid level SW flow out of the gomex across our
suwannee river valley zones weakened per the 00z jax RAOB compared
to 12z, and as the low level ridge axis builds northward through
tonight, low level convergence along the gulf coast will
transition to more ssw, and thus convection that does fire and
drift inland will not make much inland progress through daybreak
past our western tier counties, west of i-75.

Mild overnight conditions will continue, with temps trending a tad
cooler in the low mid 70s inland to mid upper 70s coast under
mostly to partly cloudy skies. With soaked grounds across much of
the area, potential for shallow ground fog increases tonight well
inland where winds will be lighter and some cloud breaks may
occur.

Aviation
MVFR ceilings will continue to impact ssi and gnv over the next
few hours, with prevailingVFR conditions at other terminals this
evening under fading -ra and ssw winds 10-13 kts along the coast
to < 10 kts inland. Cloud cover is expected to thin and break
apart further overnight, and with soaked grounds and light inland
winds, may have intermittent periods of MVFR at vqq and gnv due to
ground fog. Morning shower potential near ssi, with vcsh
advertised for all terminal Sunday afternoon.

Marine
Surge in ssw winds over outer ga waters with sustained speeds
20-23 kts this evening supported a short 4-6 hr duration small
craft advisory as low pressure developed along the surface front
just north of our waters near the sc coast. Winds expected to
gradually relax tonight to near 15 kts after midnight over the ga
waters, to 10-15 kts over fl waters as surface ridge across south
fl strengthens northward. Combined seas expected to fall from 3-5
ft to 2-4 ft Sunday.

Rip currents: low risk.

Hydrology
Locations along the santa fe river including worthington springs
are forecast to near minor flood early next week.

Climate
Record low maximum temperatures were set today across NE fl:
jacksonville: new record 79, previous record was 82 set in 1922
gainesville: new record 76, previous was 78 set in 1962
st simons set a new daily record rainfall of 1.91 inches (previous
was 1.43 inches set in 1989).

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.
