216 am edt Sun sep 23 2018

Near term Today and tonight... Surface high to the north with
weak inverted trough along the coast will continue the onshore
winds along with the possibility of coastal morning showers. Deep
moist east to southeast flow will advect showers inland today with
isolated thunderstorms possible inland this afternoon. Scattered
showers may return to the coast again late tonight as the onshore
convergent flow persists. Temperatures will be slightly above
average with highs today reaching the upper 80s coast and lower
90s inland.

Short term Monday-Wednesday... Easterly flow regime remains to
start the short-term period as an area of low pressure (98l) is
expected to be located 500 miles east of the coast. Given the
distance away from the feature, the influence on the weather over
the area will be minor if none at all. As a result, isolated
showers and thunderstorms possible primarily during peak heating
hours on Monday. Models generally drier on Tuesday and Wednesday
but unable to remove precipitation chances completely due to
patches of deeper moisture present in the easterly flow. 98l
passes well to the northeast with still little to no influence on
the local area.

High temperatures are on a slow increase throughout the short-term
as easterly flow weakens and becomes more southeasterly toward
Wednesday. Seeing the biggest change are the coastal areas as
strong easterly flow will no longer keep high temperatures in the
80s.

Long term Thursday-Sunday... For the long term period, the
focus shifts to the front to the northwest as it attempts to push
south through a deep ridge of high pressure by the weekend. The
first half of the forecast period will be dominated by weak
surface flow and scattered showers and thunderstorms, mainly
during the afternoon and evening. The weak flow will also allow
slightly stronger sea- breeze boundaries which should help to
contribute to some shower and thunderstorm activity. The first
influence of the front arrives Saturday across areas of se
georgia. A ribbon of deeper moisture within the ridge should
enhance shower and thunderstorm coverage in this area. Along with
the front, convergent onshore flow keeps precipitation chances
elevated through the overnight period into Sunday morning across
the i-10 corridor. The front slowly pushes southward, enhancing
precipitation activity into NE florida. Since this is the extended
forecast, the timing of the front will likely change as the
weekend approaches; however, for now, confidence is at least
increasing that the front could affect local weather next weekend.

Temperatures remain persistent in the low to mid 90s as the front
approaches. Heat indices will have to be watched as low level
moisture increases ahead of the front. Some guidance suggests that
if the front pushes into florida, SE georgia could experience
dewpoints in the 60s.

Aviation Isolated showers over the coastal waters may reach the
coast by morning mainly near ssi with MVFR conditions. Otherwise
vfr conditions will prevail today with scattered showers over
coastal counties this morning... Shifting inland with isolated
thunder this afternoon possibly at gnv.

Marine High pressure north of the waters will shift to the
northeast as a weak low to the east moves by to the northeast of
our waters today through Tuesday. East to southeast winds up to 15
knots will prevail with seas up to 5 feet offshore the next few
days.

Rip currents: moderate risk today due to onshore winds and
lingering long period swells.

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.
