.Update...

Minor changes were made to the Limited area over Texas to remove areas
where the rainfall and the threat of new flood impacts has ended. QPF
guidance suggests that additional heavy rainfall may be possible over
portions of East Texas later today, however this heavy rainfall should be
fairly localized and antecedent conditions are not favorable for widespread
hydrologic responses. With this in mind, the Limited area was not expanded
to the south or east.

.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 characteristicsspecifically large areas of shallow soils or
compact claywhich 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.
