What forecasters said that day

The local office's own words before this special weather statement 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 special weather statement went out at Jun 19, 3:35 PM EDT, 1 hour 9 minutes earlier.

Area forecast discussion, Jun 19, 3:35 PM EDT, 1 hour 9 minutes before

Area Forecast Discussion
National Weather Service Peachtree City GA
335 PM EDT Fri Jun 19 2020

.SHORT TERM /Tonight through Saturday Night/...

Weak upper ridging builds in as the persistent upper low finally
loses its grip on the region. Isolated to scattered, primarily
diurnal, convection still expected. Instability remains marginal
with chances for strong to severe thunderstorm development likewise
limited. Temperatures continue their climb back to around seasonal
normals.

20

.LONG TERM /Sunday through Friday/...

No major changes made to the extended forecast. A pattern change for
the latter half of the weekend is expected with weak wedging in the
upper levels. This should keep much of the area, aside from portions
of northern Georgia, dry Sunday before the approach of the next
system. By Monday we begin to transition into to southwesterly flow
aloft, bringing additional moisture to the area, with the best
chances for any precip across north and western Georgia.

By late Tuesday an approaching front will be located just north of
the area, with the parent low near the Great Lakes region. Moisture
across northern Georgia is expected to increase significantly as the
front nears the forecast area, bringing decent chances for showers
and thunderstorms to northern Georgia on Tuesday. These higher
chances for showers and thunderstorms are expected to continue on
Wednesday as the front moves into the local forecast area,
continuing on Thursday. Although, models start to show some
differences by Wednesday afternoon with the ECMWF lingering the
front somewhere across the forecast area through the rest of the
extended period leading to increased chances for precipitation. The
GFS actually clears the front by Thursday afternoon leaving the area
clear for Friday. Decided to go with a model blend for these days
bringing chance pops to the area on both Thursday and Friday.

Temperatures through the extended forecast are expected to start
slightly above average with high in the upper 80s to mid 90s, with
slightly below average temps in the 80s from mid-week on. Low
temperatures are expected to be slightly above average through the
long term period with lows in the 60s and 70s through the period.

.AVIATION...

VFR conditions are expected to predominate across the majority of
the forecast area through the period, outside of isolated to
scattered, mainly afternoon and evening, convection. Will see some
MVFR or lower visibilities in fog-prone areas, however only minimal
impacts possible at any TAF sites. Winds will remain light,
generally 6-7kt or less, and mainly from the southwest through
northwest.
