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 Jul 2, 11:21 AM EDT, 2 hours 27 minutes earlier.

Area forecast discussion, Jul 2, 11:21 AM EDT, 2 hours 27 minutes before

Area Forecast Discussion
National Weather Service Peachtree City GA
1121 AM EDT Sun Jul 2 2017

.UPDATE...
Overall forecast trends are on track. Have made a few minor
adjustments to hourly forecast grids through early afternoon based
on latest trends. Starting to see convective initiation over the
far southwest CWA/west-central Georgia. Expect coverage to
increase over the next hour or so.

&&

.PREV DISCUSSION... /Issued 724 AM EDT Sun Jul 2 2017/

UPDATE...
Updated for the 12Z Aviation Discussion.

PREV DISCUSSION... /Issued 352 AM EDT Sun Jul 2 2017/

SHORT TERM /Today through Monday/...
Models in agreement with bringing another short wave into the CWA
this afternoon and exiting Monday. Daytime heating should aid in
convection this afternoon with a diminishing trend in the evening.
However with the short wave moving into western GA tonight, will
need to keep pops in the chance category through tonight. The short
wave will move into eastern GA monday and will keep the highest pops
over the eastern part of the CWA. Can't rule out an isolated strong
storm with gusty winds this afternoon, and with a tropical
atmosphere continuing, localized heavy rain remains possible. Local
bias tables indicate guidance temps have been doing pretty good over
the past 5 days and have stayed close to a MAV/MET mix.

17

LONG TERM /Monday Night through Saturday/...
Primary concern in the long term period is location and likelihood
of diurnal convection. Large scale pattern early in the period
defined by large longwave trough over the eastern half of the
CONUS with weak westerlies as far south as AL/GA/SC. Shortwave
over mid-Mississippi valley area by Wednesday fcst to slowly move
east into KY/TN/AL by 00Z Fri. Thru Thurs afternoon, typical
diurnal coverage of SHRA/TSRA likely but could see an increase in
coverage on Friday and Saturday as front associated with shortwave
moves through the state.

For the 4th of July holiday, still appears we will have scattered
SHRA/TSRA with probs/coverage around 30-40 percent in the
afternoon and early evening dropping to around 20-30 percent after
8pm then less than 10 percent after midnight.

Too soon to tell, but 00Z medium range guidance indicating there
is some hope for slightly cooler and drier air moving in next
weekend and early next week as another shortwave digs further
south into the southeast states in NW flow.

SNELSON

AVIATION...
12Z Update...
Patchy LIFR cigs will dissipate through 14Z with a cu field
develop afterwards. Another disturbance will bring increasing
chances of tsra this afternoon and evening. Winds will be light
westerly through the forecast.

//ATL Confidence...12Z Update...
Medium on clouds heights and coverage early this morning.
Medium on timing of tsra this afternoon.
High on remaining elements.
