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 May 24, 9:35 PM EDT, 20 minutes earlier.

Area forecast discussion, May 24, 9:35 PM EDT, 20 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Peachtree City GA
935 PM EDT Wed May 24 2017

.UPDATE...
Cold front on the e side of the area with the last of the
thunderstorms associated. Showers over AL associated with
the upper Low will affect the n and portions of central GA
later tonight into Thursday before exiting.

BDL

&&

.PREV DISCUSSION... /Issued 700 PM EDT Wed May 24 2017/

SHORT TERM /Tonight through Friday/...
Complex system moving across the CWA with rotating cells
continuing across central GA. Will continue the Tornado Watch for
mainly the eastern half of the CWA along and ahead of the main
area of convection. Drier air is already moving into western GA
and this will continue to be the trend. Will end the pops from the
west through this evening, however the cold core H5 low will move
over the CWA and this will keep northern GA unstable enough for
scattered showers through the night. The H5 low move rapidly into
the Carolinas however with daytime heating and the proximity to
the cold core, there will continue to be scattered showers/tstorms
over northeast GA through much of Thursday. Skies become mostly
clear Thursday night and Friday. Winds will be gusty Thursday but
should diminish Thursday night and Friday.

17

LONG TERM /Friday Night through Wednesday/...
No major changes for the long term. Previous long term discussion
follows...

17

PREVIOUS DISCUSSION...
Shortwave ridge of high pressure will maintain dry and stable
conditions through Saturday, with temperatures quickly bouncing
back during the day Sat.

Moisture will gradually increase this weekend as W/SWerly flow
becomes more pronounced across the region ahead of large upr vortex
dropping south from central Canada over the northern Plains/upper
Midwest. By Sunday and into the first part of next week, several
shortwaves will interact with sufficient moisture and low lvl
convergence along a west-east oriented frontal boundary to
support an increasing chance of shower and a few thunderstorms.
This "system" is not looking nearly as impressive as what we've
been dealing with over the past few days but it will bring the
area more rain, on top of what we've had already. Drier air moves
in from the northwest late Monday into Tuesday with a nearly
stationary frontal boundary across north Florida/south Georgia -
where lingering chances for showers/storms will exist Tuesday.
Temperatures into early next week should remain around normal for
late May -- lower to mid 80s for highs and mid 60s for lows.

DJN.83

HYDROLOGY...
Storms with brief heavy rain continue across parts of eastern GA
but these are moving quickly and the threat of flash flooding has
ended. Will therefore cancel the Flash Flood Watch.

AVIATION...
00Z Update...
Best convection on the e side of the forecast area and will clear
MCN shortly. Otherwise Sct-Bkn VFR clouds with potential for MVFR
ceilings late tonight/early Thursday for a brief period with some
mainly shower activity for portions of n and central GA. All
MVFR-VFR ceilings diminishing Thursday. Surface winds mainly W
diminishing tonight to less than 10 kts then increasing 10-15 kts
with gusts to 25 kts during the day Thursday.

//ATL Confidence...00Z Update...
Low confidence for ceiling heights tonight.
Medium to high confidence for all other elements.

This Hazardous Weather Outlook is for portions of North and Central
Georgia.

.DAY ONE...This Evening and Tonight...

Isolated severe thunderstorms possible across eastern portions of
north and central Georgia this evening.

The severe threat will be diminishing from west to east across the
area as instability and shear begin to weaken, however both remain
sufficient ahead of a cold front for a risk of severe thunderstorms
and even a brief tornado across the eastern portions of north and
central Georgia into this evening.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday...

There is a chance for thunderstorms late Saturday into Sunday.
Otherwise, no hazardous weather is expected at this time.

.SPOTTER INFORMATION STATEMENT...

Spotters should monitor the latest information later this morning
through this afternoon for possible activation across much of
north and central Georgia.
