Our two short term weather models (HRRRand RAP) think rain will arrive before dark. The rain is coming from the SW (around Memphis) and will move NE. Don’t bet anything on the timing (models are often off by hours), just know the timing in these models are decent indicators of what’s to come.
Bottom Line: Rain is likely before dark. Here are the details:
At 3pm today, the HRRR has the rain in W Williamson Co:
By 4pm, the HRRR has Davidson & Williamson Co wet:
The RAP sends the rain in about an hour later. At 4pm, the rain is in W Williamson Co:
By 5pm, the RAP delivers rain to everyone S of I-40:
And by 6pm, everyone’s wet:
A few thunderstorms may be mixed in as the rain continues into the early morning hours Sunday. Very light, off/on rain showers are expected Sunday morning.
