Discussion...A pair of MCSs (mesoscale convective systems) from overnight remain active this morning across portions of the Southeast (focused mainly from central/northern AL/GA into portions of western SC) with scattered to numerous areas of flooding (some significant) still ongoing this morning. Convection has gradually weakened over the past several hours, while also shifting southward into drier terrain with higher FFGs. However, the northern extent of what is left of the MCSs is still managing to clip northward into rain-soaked areas from overnight, including portions of northern GA (Dalton and surroundings) where a narrow swath of 3-7" of rain fell over the last 6-12 hours (per MRMS estimates). This terrain will remain the most sensitive over the next several hours for additional (potentially significant) flooding, though with localized hourly totals of 1-2" continuing there is an expectation for some new areas of flooding developing farther south as well (particularly across the Atlanta metro where the outflow may try to stall out a bit). That said, the hi-res CAMs are not particularly intense with scattered localized totals of 1-3" per both the 00z HREF PMM and more recent HRRR runs.
