Mesoscale Precipitation Discussion 0219
NWS Weather Prediction Center College Park MD
252 PM EDT Sat May 23 2026

Areas affected...Northeast Georgia through North-Central South
Carolina

Concerning...Heavy rainfall...Flash flooding possible

Valid 231849Z - 232345Z

SUMMARY...Heavy thunderstorms, with some localized cell-training
bring an increasing flash flood threat rest of the afternoon from
northeastern Georgia through north-central South Carolina.
Rainfall rates of 1 to 2 inches/hour are expected, with localized
totals of 3 inches possible over already saturated ground.

DISCUSSION...Moist/unstable air flowing into the cold air damming
wedge front over northeastern Georgia. This front is providing a
focus for thunderstorm development generally west from Augusta.
Southerly low level flow with effective shear of 25 to 30kt is
allowing redevelopment along/beyond this front with SBCAPE of 2500
J/kg and PW of 1.9" allowing hourly rainfall of 1.5 inches/hour in
spots. The cold wedge front has been receding north which brings
the focus into the area that saw 2-5" rainfall last evening. FFG
of 1 to 1.5 inches/hour is along the current frontal location from
GA to the flash flood sensitive Columbia, SC.

Continued heavy rain over this already saturated area should cause
localized flash flooding into this evening. Instability decreases
rapidly north of the front keeping areas such as Greenville, SC
away from the heavy rain at least for the next several hours.
