Area Forecast Discussion
National Weather Service Peachtree City GA
312 AM EDT Tue Aug 22 2017


.SHORT TERM /Today through Wednesday/...
Upper ridge should break down today and allow for a return of some
low end chance pops for diurnal convection. The best chance for
showers/storms should be across central GA near the more enhanced
moisture and instability axis. No severe development is
expected, though a few strong storms cannot be ruled out.

More widespread convection is expected for Wednesday as a cold front
approaches north GA by the afternoon. Despite the better forcing,
the front and moisture axis is progged to become quite elongated
away from the main longwave energy to the north. While some storms
could become more organized, overall shear/instability parameters
still are not impressive and intensity should remain below severe.
Have maintained likely pops for north and high end chance elsewhere.

Temps slightly above climo norms this afternoon, then back to near
normal for Wednesday with some greater cloud cover/precip potential
with influence of aforementioned frontal boundary.

.LONG TERM /Wednesday Night through Monday/...
The long term beings with the cold front continuing to move out of
the CWA taking most of the moisture with it. There remains
residual moisture across parts of central Georgia and have left
chance pops across central Georgia through Friday. North Georgia
should be dry for the rest of the week. All models begin spreading
moisture back across the CWA this weekend and into early next week
although they differ on the moisture depth. Will bring chance pops
to all of the CWA beginning Saturday and continuing through the
rest of the long term.

VFR conditions with mostly clear to either a FEW near 5 kft or

sites along with a prob30 for afternoon TSRA potential. Winds
should be light SE to calm this morning then SW under 7 kts after
14/15z.
