.PREV DISCUSSION... /Issued 321 PM EDT Sat Jun 16 2018/

SHORT TERM /Tonight through Sunday Night/...

An early start to convection across portions of the NE but a
decreasing trend in activity of late as outflows were sent east of
the area. Despite this, CAPE values, even mixed layer, of 3000
J/KG plus reside across the I20 corridor. Beginning to see this
influence as isolated activity begins across the Atlanta metro.
Convergence of NE activity and residual outflows and activity
just south of AHN should coalesce in to a more substantial area of
thunderstorms for this evening. Strong to isolated severe storms
remain possible as seen from activity already seen over NE GA
today.

With deep layer moisture increasing overnight, models hinting at
even some nocturnal activity across the SW portions. Could be more
stratus and light rain with just embedded convective activity but
will bear watching. An early start to convection for Sunday as
activity to the SW develops to the NE as we acquire a SW steering
flow. Lapse rates slightly steeper but overall cloud cover will be
more substantial. All in all, expect a slight increase in rain
chances and coverage and have painted likely pops for south
central portions of the forecast area.

Deese

LONG TERM /Monday through Saturday/...

No major changes made to the extended forecast. Days 3 through 7
continue to be largely dominated by broad high pressure ridge over
the eastern US. Weak low pressure over the state will dampen out by
Monday, though the better moisture will remain over the state. The
high pressure ridge will help to suppress diurnal convection
somewhat, but there remains enough moisture, instability and heating
to trigger isolated to scattered convection each afternoon and
evening. Ridge axis moves eastward by mid week, and shifts over the
Atlantic late in the week, as low pressure approaches the Tennessee
Valley from the Midwest. Have continued with slightly higher pops
for the latter half of the week as the diminishing ridge influence
allows for better precip coverage. Expect slightly higher than
normal temperatures through the week with highs generally in the 90s
and lows in the 70s.

.AVIATION...
00Z Update...
Evening convection winding down in and near TAF sites. Watching an
outflow boundary which could impact the ATL area TAFs. Expect
convection to deteriorate by 02Z. VFR conditions will once again
give way to MVFR & patchy IFR CIGs/VIS 08-10Z. HI-REs models
consistent showing convection around CSG, held off until later in
morning. TSTM chances increase tomorrow afternoon. Winds will be
generally light SE to SW and frequently calm overnight.

//ATL Confidence...00Z Update...
Medium to high confidence in convection, winds and visibility.
Medium confidence in MVFR/IFR timing and CIG heights.
