.PREV DISCUSSION... /Issued 337 AM EDT Tue Jul 17 2018/

SHORT TERM /Today through Wednesday/...

Precip from late evening showers/storms that have largely diminished
and pushed east will again allow for some pesky morning fog with
patchy coverage and like other recent mornings, any lingering areas
of sfc convergence from old boundaries can trigger a stray shower
just about any time. Still looking like weak upper wave axis
traversing the southern half of the CWA and a front approaching the
north will focus the greater chance of afternoon/evening convection.
Fcst CAPE values are on the order of 2000-3000 J/kg so a few strong
storms can again be expected. With some mid/upper level drier air
advecting across the north, resultant PWATs will be a bit lower than
past days and should make storms not quite as efficient rain
producers but isolated flooding is always a threat with any
summertime convection.

Aforementioned front and moisture axis will be shifted farther south
for Wednesday so have confined the pops to primarily central GA and
give the north a welcomed break. The drier columns will allow for
slightly warmer temps in the period, which brings us back to near
normal in the low 90s for most areas.

Baker

LONG TERM /Wednesday Night through Monday/...

Beginning of the extended forecast sees moisture returning northward
across the region. Upper-level flow continues to amplify as the
eastern U.S. upper trough deepens. Good short wave energy in the
northwesterly flow drives another sharp surface frontal boundary into
the forecast area Saturday. Combined with moderate instability and
mid-level winds, the threat for at least slightly more organized
strong to severe storms cannot be ignored. By the beginning of next
week, the upper flow begins de-amplifying some as the eastern trough
lifts and the western ridge builds back toward the region. not seeing
enough to eliminate POPs, but we are likely to see less coverage and
a return to a more diurnal convective cycle.

.AVIATION...
18Z Update...
Expect afternoon cumulus sct-bkn035-045 to develop...gradually
dissipating this evening. Not expecting low ceilings Wednesday
morning since drier air will be advecting south...but KMCN and
KCSG could still see some mvfr. Showers and thunderstorms will
develop this afternoon and linger into the evening. Winds will
remain light west to northwest.

//ATL Confidence...18Z Update...
Medium on low ceilings for Wednesday morning.
High on all else.
