Area Forecast Discussion
National Weather Service Peachtree City GA
225 PM EDT Fri May 18 2018

.SHORT TERM /Tonight through Saturday Night/...

Seems like a near repeat of yesterday's discussion as moist,
unsettled environment persists over the area. Daytime heating as
initiated convection over central Georgia this afternoon, and expect
coverage to increase through the afternoon, particularly over far
north and eastern Georgia. Although instability is higher than
yesterday, the expectation is still for storms to remain below
severe limits. Likely to categorical pops for this afternoon will
become good chance overnight before increasing again Saturday.
Saturday's precip chances are slightly lower than the previous
forecast as coverage looks somewhat less, and still largely expect
activity to be diurnally driven.

Periods of heavy rainfall are possible, and luckily soils have been
able to dry somewhat between waves of precip.  At this time, QPF
through the short term is under 1 inch. A Flash Flood Watch is not
necessary at this time.

Temperatures will be slightly warmer Saturday than this afternoon -
particularly if the cloud and precip coverage isn't as substantial -
with highs in the mid to upper 80s over the area. Overnight lows
will be in the 60s to near 70.

31

.LONG TERM /Sunday through Friday/...

Very few changes made to the extended forecast grids. Medium-range
models continue to show similar overall, large-scale, pattern
evolution with some variation in the smaller-scale features. However
the basic result is a continued period of scattered, diurnally
driven, convection. Upper pattern transitions to weak ridging over
the weekend as the current broad upper low opens up and lifts out of
the region. However the ridge is far from dominating and ample
moisture continues to stream over the region around the western edge
of the large surface high over the western Atlantic.

.AVIATION...
18Z Update...
SCT-BKN MVFR/VFR cigs this afternoon will continue to improve
slightly. Precip will impact the area, but latest thoughts are for
it to be less in coverage than yesterday. Cigs will degrade back
to IFR or low MVFR overnight. Winds will be SSE to SW, and
gradually all shift to the SW by the end of the period. Speeds
will be 8 kt or less. TS potential returns Saturday afternoon.

//ATL Confidence...18Z Update...
Low on TEMPO -TSRA this afternoon.
Medium on cigs.
High on all other elements.
