Temps and dewpoints will rise through the afternoon, as shown here by the GFS model:
This lifting warm front is associated with a surface low moving out of the Plains into the Ohio Valley. That low is going to drag a cold front across Middle Tennessee and set off another round of rain, and perhaps storms — some possibly severe.
Off and on rain will continue through Sunday afternoon into tonight. Light and nondisruptive, not a washout.
The HRRR model thinks the heavier stuff will arrive around 4 am. Either way, this is an early shift / while we sleep heavy rain event, almost 1″ expected. Isolated storms possible but nothing severe or concerning. Sleep peacefully tonight.
