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.

Area forecast discussion, Jul 8, 9:04 PM EDT, 13 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Peachtree City GA
904 PM EDT FRI JUL 8 2016

.UPDATE...
Isolated to scattered showers/storms...with isolated strong-
severe...expected for a few more hours. Unsure about the
convection in southern TN to the W. It is expected to weaken
but will need to be watched.

BDL

&&

.PREV DISCUSSION... /Issued 700 PM EDT FRI JUL 8 2016/

PREV DISCUSSION... /Issued 350 PM EDT FRI JUL 8 2016/

SHORT TERM /Tonight through Saturday Night/...
Current radar loop shows some isolated showers and thunderstorms
across Central and extreme North Georgia. The main area of
convection is still across Tennessee and Kentucky and moving
slowly south and east. the HiRes models are not in very good
agreement with the timing and intensity of this wave affecting GA
but they do agree that it will. Just looking at the way they
initialized it appears the 4kWRF has the best handle on this and
it shows the complex of thunderstorms moving into N GA around 22z-
23z. It also shows this complex diminishing as it moves south
into the area with very little remnants left over the area by 03z-
04z. This appears to fit well with SPCs Day 1 marginal risk
across North and eastern portions of the state. The HiRes models
seem to be in a little better agreement for Sat...showing
scattered showers and thunderstorms across the entire area as
next wave moves in with upper level West to Northwesterly flow.
Diurnally driven instabilities also increase across the area Sat
so this also matches well with SPCs day 2 outlook thinking of just
a General risk across the state.

Heat Index values are still expected to get into the 105-108
degree range Sat afternoon across portions of East Central GA.
Will need to issue another Heat advisory for a similar area as
today for Sat afternoon.

01

LONG TERM /Sunday through Friday/...
Made a few tweaks to the extended portion of the forecast.

An unsettled period of weather is expected from Sunday through early
next week. A weak boundary will remain situated across northern GA
through Monday/early Tuesday, but should become diffuse by the
middle of the week. The mid level flow will remain slightly nw/w
through the period...and perturbations in the flow are expected to
interact with the boundary...serving to focus scattered showers and
thunderstorms. PWATS at or above 2 inches are expected into
Tuesday...so any storms will be very efficient rainfall producers.

Ridging tries to build in for the middle part of the week. However,
models are keeping a weakness in the ridge overhead.

The highest pops should remain across northern GA through much of
the extended period. Have adjusted values slightly upward Sunday
through Tuesday.

NListemaa

AVIATION...
00Z Update...
VFR conditions expected to continue. Isolated showers/storms
around ATL will dissipate by later evening. Surface winds
diminishing to WSW around 5 kts or less for the overnight.
High level ceilings possible late tonight and early Saturday.
Chance for afternoon showers/storms on Saturday with surface winds
around 10 kts with gusts near 20 kts.

//ATL Confidence...00Z Update...
Low confidence for effects of any evening showers/storms.
Medium to High confidence all other elements.
