.Southern Plains into the Lower Mississippi Valley...
The potential for flash and urban flooding, along with isolated new or
renewed river flooding, returns today through Tuesday. While recent
rainfall has increased soil moisture, levels remain near 50% (0-10cm RSM,
NASA SPoRT), suggesting the ground still retains some capacity for
infiltration. However, the flood threat persists due to the region`s
specific soil characteristics, specifically large areas of shallow soils or
compact clay which will promote rapid runoff regardless of the average
saturation levels. HEFS/PQPF guidance and the HRRR-driven National Water
Model Short-Range Rapid Onset Flooding forecast support this assessment,
indicating that isolated river, flash, and urban flooding remain possible.
