Short term today through Sunday
A moist tropical air mass remains in place over our area even though
the remains of cindy have become absorbed in the upper flow. With
numerous old boundaries across us... And looking at radar returns
over al... The possibility of training showers developing today seems
reasonable. For now... Have kept the highest pops from atlanta to
athens this morning... Looking at orientation of showers to our
west... And then spreading the higher pops into central ga by this
afternoon. Pw values remain above two inches today so areas of heavy
rain can be expected. The flash flood watch will remain in
effect as is. A few strong thunderstorms are possible especially
with any breaks in the clouds this afternoon. Models show some
drying working into the north after 00z. The upper trough
deepening over the great lakes should help push the front into
south ga during Sunday. Have kept the north half of our area
dry for Sunday.

Temperatures will remain on the cool side due to clouds and rain
today but any breaks in the clouds could push the temperatures up.

Long term Sunday night through Friday
The aforementioned front that interacted with remnant moisture
from TS cindy will finally sag south of the area to start the long
term. The boundary placement will truly dictate the amount of
thunderstorm coverage seen across the southern portion of central
ga Monday afternoon. Based on the strength of the incoming surface
high, feel the boundary should push far enough south to only have
slight chance pops across the far southeastern portion of the
cwa. High pressure will continue to build into the area from the
north helping to keep much of the area dry through mid-week as the
boundary exits our region to the south.

There is a bit model discrepancy in terms of shower and
thunderstorm development Tuesday afternoon. A few of the model
solutions illustrate enough moisture associated with a mid level
trough to resolve scattered showers and thunderstorms, especially
across the higher terrain. With little model continuity to build
confidence at this point, have kept Tuesday dry. However, will
need to watch this impulse to see if it has enough moisture and
dynamics to support precipitation. Honestly, it is rare to see
such a progressive pattern this time of year, but it can not be
ruled out. Otherwise, expect fairly quiet conditions through
Wednesday night as the surface high shifts offshore. Return flow
will develop in earnest by Thursday afternoon helping to initiate
diurnal convection, especially across western ga with better
surface convergence and mid-level support noted. Better coverage
of showers and thunderstorms by Friday as mid level impulses
riding the ridge move northeast through ga.

Temperatures will be pleasant for this time of year, running a
couple degrees below normal. It will feel even better given the
lack of humidity that often plagues the region in the summer.

Enjoy!

kooking at radar... Expect a band of showers thunderstorms vicinity
of katl to kahn and south to develop lasting into the
afternoon. MVFR with areas of ifr should last into mid morning
then gradually improving. Winds light southwest increasing to
10 to 12kt after sunrise. Some improvement overnight with increasing
northwest winds.

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.
