Update...
upper low and surface low have pushed well off the coast of the
Gulf states. Scattered showers continue, mainly across the western
areas of the County warning forecast area. Will be updating the forecast to tweak pops.
Otherwise, no major changes needed. Temps/dews look on track. A few
peeks of sun are possible, but most locales should remain mostly
cloudy/cloudy.

Short term /today through Thursday/...
models in general agreement with the short term. The 500 mb low over the
lower Mississippi Valley will move southeast toward southern Florida
by this evening. This will pull the moisture southward. At this time
widespread rain remains over western Georgia. This area is not expected
to advect eastward but to remain nearly stationary early this
morning. As the 500 mb low moves toward South Florida, the rain will
slowly end from the north this afternoon and evening. Dry conditions
are expected for Thursday along with diminishing clouds.
Temperatures today and Thursday will again run above normal with
some areas approaching record highs, especially across central
Georgia, on Thursday.

Long term /Thursday night through Tuesday/...
the extended forecast begins with a frontal system exiting the
area with minimal moisture lingering across the region. The next
frontal system moves into the state at the beginning of the
extended period and there is some increased instability with it.
This next short wave and associated cold front will move out of
the Midwest and into the eastern US Friday evening/night. With the
increased instability associated with it have continued with the
mention of isolated thunderstorms through Sat morning. This second
front will push east of the County Warning Area Sat afternoon and clear things
out for Sunday. Another frontal boundary pushes south out of the
Great Lake states Sunday evening and appears to stall across Tennessee/NC
Mon morning. Its proximity will bring increased moisture to north Georgia
with increased chances of showers Monday and Tuesday.
