Area forecast discussion, Apr 24, 8:10 PM EDT, 1 hour 58 minutes before

Area Forecast Discussion
National Weather Service Peachtree City GA
810 PM EDT Sat Apr 24 2021

.UPDATE...

Another round of thunderstorms has entered northwest Georgia and
will continue to push east towards the ATL metro area over the
next couple of hours. Some splitting cells, with dominant hail
producing left moving storms, have been observed as well. A
favorable environment remains across north Georgia for strong to
severe thunderstorms, which will be capable of produce large hail
and damaging wind. Severe Thunderstorm Watch remains in effect
until 10 PM EDT this evening.

Updated for the 00Z Aviation Discussion.

.PREV DISCUSSION... /Issued 555 PM EDT Sat Apr 24 2021/

UPDATE...

Convective development is ongoing roughly along the I-85
corridor, as much of this area was able to clear out and
destabilize this afternoon. A favorable environment is thus in
place for strong discrete cells capable of producing large hail
and damaging wind gusts. PoPs have been updated to reflect the
latest trends and another Severe Thunderstorm Watch has been
issued for portions of north and west Georgia until 10 PM.

King

PREV DISCUSSION... /Issued 407 PM EDT Sat Apr 24 2021/

UPDATE...
Updated to add the severe thunderstorm watch.

PREV DISCUSSION... /Issued 301 PM EDT Sat Apr 24 2021/

SHORT TERM /Today through Monday/...
Warm front looks to be along or just north of the I-20 corridor. The
forecast dilemma for today remains the potential for convective
development this afternoon and evening...and if it will be
strong/severe. Most of the CWA is now in the warm sector and clouds
have begun to break. With some ascent provided by a 500mb
trough/cold pool, do expect additional thunderstorms to develop. It
may take awhile for the airmass to recover after this mornings
widespread rain...so timing should be late afternoon/early evening.
The primary hazards would be damaging wind gusts and large hail. An
isolated brief tornado cannot be ruled out.

High pressure and dry conditions anticipated for the remainder of
the short term period of the forecast.

NListemaa

LONG TERM /Monday Night through Friday/...
Dry start to the extended with a surface high sinking into the
Carolina with a broad trough aloft approaching the CWA. This ridge
will be the primary weather inhibitor that keeps the area PoP
free through the most of the extended. Approaching Wednesday,
synoptic pattern begins a slow transition with model guidance
solutions showing a mid/upper level trough deepen over the
southern Great Plains. Past Wednesday however, guidance differs
drastically on what exactly they want to do with this trough. The
GFS progs a very deep single trough developing with a surface low
moving up the Ohio River Valley, bringing the associated cold
front across the area on Thursday Night/Friday morning.

Meanwhile, the European model has the same deep trough developing,
but continuing to deepen into a cut-off upper low that eventually
becomes stacked over Texas. Euro solution also shows another long
wave trough starting to sink down into the Midwest during this same
period, while the GFS is really sticking with one deep trough
system. So in short and to put it lightly, there is a great deal of
model disparity in the long term past Wednesday so went with low
range slight chance pops starting Thursday afternoon, lasting
through and topping out at mid range chance on Friday.

.AVIATION...
00Z Update...
Another line of TSRA is approaching the metro ATL TAF sites, with
a TEMPO for TSRA from 00-02Z. Ceilings are expected to lower to
MVFR after 02Z. Some scattered IFR level clouds are furthermore
possible underneath the MVFR deck after 06-07Z before ceilings
start to scatter out between 11-13Z. IFR ceilings are currently in
place at CSG/MCN for the next couple of hours before improving to
MVFR. SW winds at 6-10 kts to start the period will shift to NW in
the early morning hours before sunrise, increasing to 9-13 kts
with gusts up to 20 kts.

//ATL Confidence...00Z Update...
Medium confidence on all elements.
