Area forecast discussion, Jun 9, 1:57 PM EDT, 5 hours 49 minutes before
Area Forecast Discussion
National Weather Service Peachtree City GA
157 PM EDT Sat Jun 9 2018

.PREV DISCUSSION... /Issued 343 AM EDT Sat Jun 9 2018/

SHORT TERM /Today through Sunday/...
Northern Gulf upper low will continue to dampen and drift northward
into the area, which will linger a more moist and conditionally
unstable regime through the weekend. Convective development will
again be initially diurnally driven for most areas with chance pops
for the afternoon and likely pops in the NE mtns for orographic
enhancement. We could again see a few strong to severe storms given
SBCAPE expected to be close to 2000-2500 J/kg and if stronger
updrafts/elevated cores get extra forcing from any converging
outflow boundaries later. Sunday looks to be pretty much a repeat of
today given little change to the airmass. Temps also will be near
normal both days with highs in the upper 80s to low 90s for most
areas.

Baker

LONG TERM /Sunday Night through Friday/...
A tropical airmass will remain over the CWA through the long term.
Each day will see scattered to possibly numerous thunderstorms,
mainly in the afternoon and evening hours. The GFS continues to
show a tropical system moving into the northern Gulf by the end of
the week, however the ECMWF and Canadian are showing a H5 High
over the southeast with no tropical system. Will maintain a
ECMWF/Canadian solution.

.AVIATION...
18Z Update...
Generally VFR conditions expected through the period. Afternoon
convection has initiated and expect the main period of TS concern
to be through 02Z. For now have TEMPO TS with VRB10G20KT for
18-22Z, but this will need to be adjusted through the afternoon.
Repeat expected for Sunday, so have already added PROB30 for
Sunday afternoon at KATL. Winds have shifted west and are expected
to stay W-NW at 6kt or less. Patchy MVFR visibilities are
possible after 08-10Z.

//ATL Confidence...18Z Update...
High on all elements.
