.UPDATE...
Tropical Storm Fred is continuing to move inland across the
Florida panhandle/southeastern Alabama towards the local forecast
area. Through the overnight hours, Fred is still expected to
weaken to a tropical depression. Across the CWA, light showers
have overspread much of the area out ahead of Fred, with rainbands
moving into southwestern portions of the area. The wind advisory
was extended further north and east with the most recent update
and still remains in effect through Tuesday evening. The Flash
Flood Watch remain in effect through Wednesday morning with little
to no changes to the afternoon forecast.

SHORT TERM /Tonight through Tuesday Night/...
Tropical Storm Fred continues to move towards the CWA this afternoon
with outer convective rain bands moving into FL with heavy rainfall
and gusty winds. With a more easterly track Fred is still progged to
move on shore this afternoon/evening and then track northward
into the CWA.
As mentioned in todays earlier update, starting this evening
through tomorrow night, QPF amounts of 2-5" will be possible
across north and northeastern GA. Of course locally heavier
amounts under stronger rain bands will be possible. In
collaboration with WPC and neighboring offices a Flash Flood watch
has been issued and covers much of GA starting late tonight and
expiring Wednesday morning. Also, wind gusts up to 45 mph mainly
along a line from Sumter county north towards Jasper county will
be possible. As a result a wind advisory continues to be warranted
and is in effect from midnight tonight to tomorrow afternoon. The
caveat with the windy advisory is that there is a chance that
western GA does not meet wind advisory criteria right away or even
at all, but we have included these counties to take into account
any wobble in the track associated with Fred. Although Fred will
enter the CWA this evening/overnight limiting the initial
instability and shear by tomorrow afternoon, when peak heating
occurs, destabilization will support some severe storms and even
an isolated tornado across our very far NE zones.
Tomorrow night Fred will quickly begin to dissipate and move
northeast of the CWA as impacts do the same. However, locally
heavy rainfall will still be an issue for areas across far
northern GA until late tomorrow night.

LONG TERM /Wednesday through Monday/...
Quiet long term portion of the forecast compared to the short term.
High pressure will remain centered along the SE coast through
Thursday. The top of the ridge gets flattened a bit on Friday as a
shortwave trough moves through the flow. After the shortwave trough
passes, high pressure will build across the Gulf Coast states and
remain in place through the remainder of the forecast period. A few
pieces of mid level energy may impact the CWA during this time as
they round the northern periphery of the high center. Quiet surface
patter as weak high pressure will dominate.

AVIATION...
00Z Update...
SHRA will be likely through the overnight hours and into much of
Tuesday as TS Fred crosses the area. Cigs should quickly
deteriorate after about 04Z to IFR and remain until Tuesday
evening. Winds are expected to increase at all sites with gusts
15-30 kts possible through Tuesday morning, although exact wind
speeds will be dependent on track of Fred. SHRA looks to end
19-22Z across metro taf sites with cigs lifting to MVFR/VFR
thereafter.
//ATL Confidence...00Z Update...
Medium confidence on all elements.
