Afternoon update...

short term tonight through Friday night ...

models in pretty good agreement with the short term. High pressure
centered over the northern gom will hold through Friday and then
break down as the midwest trough digs and moves eastward Friday
night. Low level flow late tonight and Friday will bring in atlantic
moisture in the form of low clouds but should not bring in any
precipitation. As the upper trough moves into the eastern u.S. The
associated cold front will move the tennessee valley Friday night
and into north georgia toward daybreak Saturday. Scattered showers
will spread into extreme north georgia Friday evening, and across
much of north georgia after midnight Friday night. Instability will
be very low so am not expected thunder Friday night.

long term Saturday through Thursday ...

beginning Saturday, a surface frontal system will push into
northern georgia. Ahead of the front, mid-level lift from
positive vorticity advection (pva) associated with a broad
longwave trough over the eastern CONUS will make its way over
georgia with just enough subtropical moisture ahead of it to
produce some rain showers across the area. Recent trends, have
been showing weaker areas of PVA moving into the region than
previously, and thus producing lower pops and rainfall totals. As
it stands, we are expecting no more than a quarter of an inch of
rain on average with the highest rainfall totals expected further
north. As the cold front sweeps through on Saturday, a cooler,
dryer air mass will follow dropping pwat values to a quarter inch
and high temperatures on Sunday expected to be in the 60s, a
shocking 10 degree below normal, if only for a day.

The area will remain mostly sunny and dry until moisture begins to
make a comeback to the area in the middle of next week. The next
wave of precip is expected to come through as early as next
Thursday, but as of this morning, that's all the models agreed
upon with major discrepancies between the GFS and the euro.

Since, both models have begun to come together in regards to the
overall pattern, but timing and maturity of a potential low
pressure system, as well as a possible wedge front pushing into
georgia from the northeast, are all in question. What we're
confident in at this point is that we'll have rain across the
area around this time, but exactly when, where, how much and by
what means are yet to be determined.

00z update...

vfr conditions will prevail through most of the night. However,
returning moisture from the east will bring an increase in
ceilings in the 2500-3000 ft range by late tonight in the
southeast and by Friday morning farther north at atl ahn sites.

Ceilings are expected to lift toVFR by late afternoon Friday.

Winds will remain from the east to southeast through the forecast
period at 4-7kts.

Atl confidence... 00z update...

medium confidence on ceilings late tonight and Friday. High
confidence on remaining elements.

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.
