short term today through Saturday ...

scattered showers and isolated thunderstorms exist across primarily
far north georgia this morning as a result of weak shortwave energy
traversing the area. At the surface, a cold front will drift
southward into the tennessee valley toward north georgia today.

Abundant gulf moisture is in place across the area courtesy deep
southwest flow, which in combination with the approaching surface
front and weak upper impulses will lead to more widespread afternoon
and evening convection today. The highest coverage will be in north
georgia in vicinity of the approaching surface front, though
additional scattered activity will be possible elsewhere. Pw values
at or above 2 inches will contribute to the risk of locally heavy
rainfall.

As the surface front sags into the area overnight, some activity may
linger into the early overnight hours, though coverage is expected
to gradually lessen with loss of daytime heating. On Saturday, the
diffuse front will push into central georgia providing a persistent
focus for shower and thunderstorm development. Locally heavy
rainfall will remain the primary concern with the very moist airmass
remaining in place. Meanwhile, a weak surface "wedge" will build in
from the northeast Saturday, bringing the beginnings of cooler
easterly surface flow.

Temperatures today will range from the mid-to-upper 80s in north
georgia where the highest convective coverage is anticipated to the
mid 90s in central georgia. Highs Saturday will drop a few more
degrees with the impact of more clouds and shower and thunderstorm
coverage.

long term Saturday night through Thursday ...

models still in general agreement in the long term pattern. A
broad trough deepening over the great lakes this weekend still
looks like it should push a frontal boundary into ga where it may
stall in the vicinity of central ga on Saturday. Models consistently
show a wedge building into north ga late Saturday and possibly
lasting into Monday. This configuration should keep chance to
likely showers and thunderstorms across the area. The wedge breaks
down on Tuesday and then another deep trough builds into southern
canada... Pushing another front southward toward ga by mid week.

Some drying indicated for north ga by the end of the period as
upper flow becomes more northwesterly... But have held on to chance
pops through Thursday. High temperatures should moderate mostly
into the 80s by the weekend and into next week... With some 70s in
the higher elevations.

12z update...

vfr conditions are expected to largely prevail through the taf
period. Scattered shra tsra activity will develop this afternoon,
especially after 18z. While the highest coverage is expected at
atl area sites and north, scattered convection is possible at any
taf site through evening. W to SW winds at 3-7kts can be expected
through 00z becoming light thereafter with a shift toward ne
expected 12-15z Saturday.

Atl confidence... 12z update...

high confidence.

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.
