SHORT TERM /Today through Wednesday/...

As the short term period begins, north and central Georgia is under
the influence of a strong surface high pressure and northwesterly
flow aloft, which is keeping relatively dry conditions in place
across the region. In spite of some moisture trapped underneath an
inversion contributing to a scattered cumulus field at 4-6 kft, only
minimal rain chances at best are expected across the far southern
tier in the mid to late afternoon. The overall pattern will be in
transition on Tuesday and Tuesday night. The northwesterly upper-
level flow pattern will transition away from the area on Tuesday as
a broad upper level ridge builds over the eastern CONUS. The surface
high will also shift eastward towards the western Atlantic, and the
low-level flow will gain a southerly component and allow for
gradually increasing moisture on Tuesday. Temperatures are expected
to remain near seasonal normals, with highs mainly in the 80s and
lows in the 60s.

LONG TERM /Wednesday Night through Sunday/...

By early Wednesday, high pressure center has moved well offshore but
the ridge axis remains situated across the CWA. The western edge
of the ridge axis should begin to erode later on Wednesday allowing
for deeper Gulf moisture to stream northward. The trend should
continue through Thursday and Friday but a frontal boundary will
begin to approach from the north. Not confident that the frontal
boundary will make much southern progress.

There is much uncertainty regarding the evolution of the potential
tropical system currently near the Yucatan/Bay of Campeche. The NHC
is currently not forecasting much movement through the end of the
week, but some northward momentum is possible during the weekend.

Will continue with a persistence forecast for the weekend.
