A localized, yet appreciable flash flood threat may emerge from this activity through 03Z. Discussion...Well organized clusters of strong convection continue to propagate east-southeastward across the discussion area.=20 Additionally, local cell mergers have prolonged and enhanced rainfall rates on a localized basis, with estimates of 1-3 inch/hr rates noted per MRMS. These rates are not surprising given 2-2.4 inch PW values immediately downstream of the persistent clusters along with slow overall cell movement. On their east-southeastward track, these cells are expected to impact the I-20 corridor from Columbia to Augusta through 03Z.=20 These areas are relatively sensitive to excessive rainfall, with FFG thresholds generally less than 1.5 inch/hr along the corridor (locally lower in the urban/populated areas). Should this convection hold together and continue producing excessive rainfall, a locally significant flash flood threat could unfold.=20 The organized nature of the cells and lingering areas of 1500 J/kg MLCAPE immediately downstream of the convection suggests fairly strong potential for heavier rainfall to reach sensitive areas across the discussion area through 03Z.
