What forecasters said that day

The local office's own words before this river flood 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 river flood warning went out at May 24, 8:52 PM EDT, 1 hour 38 minutes earlier. Its key messages:

  • An unsettled weather pattern will bring widespread chances for showers and thunderstorms throughout the week ahead.
  • A Flood Watch is in effect for portions of north and west Georgia through late Monday. High rainfall rates within the watch area may lead to increased instances of flash flooding.
  • A few strong to severe thunderstorms are possible each afternoon, capable of producing localized damaging wind gusts.

.KEY MESSAGES...

  - An unsettled weather pattern will bring widespread chances for showers
    and thunderstorms throughout the week ahead.

  - A Flood Watch is in effect for portions of north and west
    Georgia through late Monday. High rainfall rates within the
    watch area may lead to increased instances of flash flooding.

  - A few strong to severe thunderstorms are possible each
    afternoon, capable of producing localized damaging wind gusts.

.UPDATE...
Issued at 845 PM EDT Sun May 24 2026

Coverage of showers and thunderstorms is becoming less with an
overall downward trend in intensity. Though a northward moving
cluster of storms across east-central Georgia continue to bring
locally heavy rainfall and frequent lightning to parts of
Washington, Hancock, Warren, Glascock, and Jefferson Counties. The
wedge front is current situated across far northeast Georgia --
Blairsville to Flowery Branch to Vesta GA. This boundary caused
some interesting interactions with storms just a little bit ago
but these have since pushed east out of our forecast area. Tonight
will essentially be a carbon copy of yesterday -- isolated
showers or drizzle overnight, low clouds and patchy dense fog that
will likely stick around through at least late morning (10-11am).
A lack of any substantial clearing this evening has precluded any
fog development thus far but this will be something to monitor
over the next several hours. Locations receiving heavy rainfall
will be susceptible to patchy dense fog tonight through early
Monday morning. No notable changes made with this update as the
forecast remains on track.

&&

.SHORT TERM...
(This afternoon through Monday)
Issued at 229 PM EDT Sun May 24 2026

The Southeast remains in a regime characterized by abundant
moisture (PWATs north of 1.7" and dewpoints in the upper 60s or
higher), supported by deep southwesterly flow around vertically-
stacked ridging across the western Atlantic. Sunday has been off
to a gloomy and misty start, with yesterday's showers and
thunderstorms serving to reinforce and retain the CAD wedge
overspreading the eastern two-thirds of the forecast area.
Erosion will continue from south to north, but high temperatures
are likely to be several degrees cooler under more persistent
overcast skies (generally in the upper 60s to lower 70s for areas
north and east of the Metro). Elsewhere, expect highs in the mid-
to-upper 80s.

Convection will continue to be diurnally-enhanced and summerlike,
with highest coverage (and chances) in the afternoon, with a lull
(but chances still non-zero) overnight. Some quasi-organization of
showers and thunderstorms is expected this afternoon, bolstered by a
remnant Gulf MCV lifting to the north and east. ACARS, HiRes model
guidance, and this morning's observed 12Z sounding continue to show
nearly-saturated profiles with tall, skinny CAPE -- as such, any
storms that form will be efficient rainfall producers. A Slight
(level 2 out of 5) Risk for Excessive Rainfall has been analyzed
across portions of the forecast area both today and Monday, and
localized flash flooding concerns will continue. Training storms, or
storms that anchor to any lingering outflows/boundaries, could drop
a quick 2-3" of rainfall (and potentially more, depending on rain
rates). A Flood Watch has been issued for areas generally along and
north of I-85 to highlight increased chances for localized flash
flooding and flooding of creeks and streams through late Monday.

The strongest upward pulses will likely have precip-loaded
downdrafts capable of producing isolated damaging wind gusts, but
the summerlike environment with relatively unimpressive kinematics
should preclude severe concerns from becoming widespread or
numerous. Any clustering of storms will locally bolster chances for
damaging winds.

Tomorrow (Memorial Day) will be a near-carbon copy
of today, with additional rounds of showers and thunderstorms
expected into the afternoon and evening. Further organization (and
isolated severe potential) will be possible along any remnant
boundaries/MCVs from this afternoon's convection, but these features
will be difficult to pinpoint until today's activity has fizzled
out. Be extra cautious if outdoor festivities are planned through
tomorrow, and ensure proper precautions are being taken if warnings
are issued.

&&

.LONG TERM...
(Tuesday morning through next Saturday)
Issued at 229 PM EDT Sun May 24 2026

Daily diurnally driven showers and thunderstorms will continue to
affect most of north and central Georgia through the long term as we
continue this wetter period. Current CPC outlooks continue to show
leaning above normal through the 8-14 day outlook. Looking at the
synoptic pattern the area will be in the middle of the blocking
pattern through the end of this week at least with troughing to our
west near the ArkLaTex and high pressure pushing in from the east in
the form of the Bermuda High sandwiching the area in between these
two upper level features. This will funnel moisture in from the S/SW
and keep PWs elevated. Current forecast PWs in the 1.5-2" which are
above average for this time of year. Ultimately these diurnally
driven showers and storms will have the main threats of gusty winds,
small hail, and frequent lightning in addition to being capable of
producing heavy rainfall that could lead to localized flooding in
low lying areas as well as poor drainage/ urban areas. Temperatures
will continue the trend of mid 80s during for highs and mid 60s for
lows which will be near normal to slightly above normal.

&&

.AVIATION...
(00Z TAFS)
Issued at 734 PM EDT Sun May 24 2026

Sct TSRA will continue to impact mainly RYY/MCN this evening with
SHRA/DZ psbl at the remaining sites until at least 03z. SE/SW sfc
winds will diminish overnight with periods of vrb winds likely
thru at least 12z. Cigs and vsbys will gradually lower, earlier
for sites where TSRA ended earlier and a little later at RYY/MCN.
Dropping to IFR/LIFR as early as 03z lasting through 15-16z with
slow improvement thereafter. Winds shift to the SW btwn 16-18z at
all sites less than 8kts. TSRA will be possible after 18z Monday.

lightning.

A Flood Watch remains in effect for north Georgia as locally
heavy rainfall will likely lead to increased chances for flash
flooding.

.DAYS TWO THROUGH SEVEN...Monday through Saturday...

A Flood Watch remains in effect through Monday evening for
increased flash flooding concerns. Scattered to numerous
thunderstorms are expected Monday through Saturday, especially
during the afternoon and evening hours, which will bring the risk
for locally heavy rainfall and frequent lightning. A few storms
could become severe.
