Near term through Monday ...

high pressure will be northeast of the region through tonight. This
will continue the moist onshore flow pattern with scattered showers
and possibility for embedded thunderstorms moving inland this
afternoon. This activity will dissipate with loss of diurnal heating
this evening. A wave of low pressure will move northwest into the
western atlantic Monday afternoon. Between the high and the
approaching the wave, an increased pressure gradient develops over
the coastal waters, which will enhance the onshore flow. This is
expected to increase precipitation potential late tonight through
Monday.

Short term Monday night through Thursday ...

for Monday night into Tuesday, high pressure will be to the north,
with a wave of low pressure to the east over the western atlantic.

This wave will disrupt the moist onshore flow pattern, and should be
far enough away that a lower chance for convection is anticipated
for Tuesday. Highs Tuesday will range from the upper 80s along the
coast to the lower 90s inland.

High pressure will build to the east northeast Tuesday night into
Wednesday, as a cold front approaches from the northwest. This front
will stall just to the northwest Thursday, with the high remaining
to the east northeast. This pattern will result in a warm southerly
flow for Wednesday into Thursday scattered diurnal convection and
highs in the lower 90s.

Long term Thursday night through Sunday ...

remnants of stalled frontal boundary will linger across SE ga
through at least Saturday, remaining a focus for additional
convection this period. Otherwise, high pressure will build to the
north northeast this period resulting in another onshore pattern for
the weekend.

Temperatures will be above normal Friday, then trend closer to
normal for Sunday.

Marine
High pressure will be north of area waters through tonight. A
wave of low pressure will move northwest through the western
atlantic Monday into Tuesday. High pressure will build to the
northeast mid week, as a front moves into the southeastern us and
stalls.

Rip currents: high risk today NE fl. Moderate risk today SE ga.

Moderate risk Monday.

Aviation
Sct to broken cumulus rest of today with a few showers expected but for
most part, these showers will be west of the TAF sites. Winds will
be east at about 10 kt into the evening then becoming light overnight.

Like a broken record, a few showers are expected along the coast
later tonight, coming in off the warm atlantic waters, with perhaps brief
cig vsby restrictions but given the low chances will keep at vcsh at
this time.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
