What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Atlanta, GA wrote its last area forecast discussion before this severe thunderstorm warning went out at May 22, 7:29 PM EDT, 30 minutes earlier.

Area forecast discussion, May 22, 7:29 PM EDT, 30 minutes before

Area Forecast Discussion
National Weather Service Peachtree City GA
729 PM EDT Fri May 22 2020

.UPDATE...
Showers and scattered thunderstorms continue across much of the
CWA this evening. Activity should continue for at least the next
couple of hours. However, the hi-res models do not have a great
handle on the activity across western TN. Will have to keep an
eye on pops across the north.

Have raised pops in the south for the large cluster of storms.

&&

.PREV DISCUSSION... /Issued 425 PM EDT Fri May 22 2020/

UPDATE...
Updated the products to cancel the watch. Otherwise, no major
changes.

PREV DISCUSSION... /Issued 350 PM EDT Fri May 22 2020/

SHORT TERM /Tonight through Saturday Night/...

OH Valley closed upper low pulls northeast tonight and early
Saturday...as upper ridge builds over the area through the
remainder of the period. We remain on the southern fringes of this
low with a moist and generally unstable air mass prevailing. A
thunderstorm complex that had affected north GA was pulling east
of the forecast area this afternoon. With abundant sunshine over
the remainder of the area...thunderstorm development was beginning
over central counties. Convection should diminish during the
overnight...but have kept some low pops across the far north close
to the upper low. Saturday should see more of a diurnal pattern as
the ridge builds over north and central GA.

41

LONG TERM /Sunday through Friday/...

Long-term forecast trends remain somewhat unsettled despite general
trend dominated by upper ridging anchored along the east coast.
Forecast area remains on the southwestern periphery of the ridge
with better subsidence to the north and east. Should see at least
isolated to scattered convection each day with a diurnal bias. Low-
level flow becomes east to southeasterly by Monday which may help to
moderate the potential warmth under the edge of the upper ridge.

&&

.AVIATION...
00Z Update...
Scattered evening convection will continue for the next few hours.
Have continued the TEMPO group for a few more hours. VFR
conditions expected after the convection and into tomorrow. Winds
may try to go light and variable overnight, but stuck with the SW
side. Scattered convection expected again tomorrow, but
confidence/pops too low at this time for a prob group.

//ATL Confidence...00Z Update...
Med confidence all elements.
