After yesterday's washout, today also looks like it could damper some of your plans this afternoon. I'm putting the chance at seeing these rains/storms at 80% for all of Mid. TN. I would go with 100% by what the models are saying, but I can't do that until it actually starts raining. High's today are going to be well into the 80's like yesterday, but with the rain and t'storms come marching in, the temps. will back off. Many locations in TN got around or over an 1" of rain with some hail and wind damage reports in Moore County (southern Mid. TN) and over in Madison County (Jackson, TN) in TN. We more then likely won't have a squall line event today, but these pop-up storms can be just as threatning as a squall line when it moves through. Here's some of the regional highs for today as well as the chance of precipitation. Flash Flooding is going to be a concern again for today I believe. Remember the key phrase that we all should know if we see suspected high waters, "Turn Around, Don't Drown".
Nashville: mid to upper 80's; 80% chance
Clarksville: low to mid 80's; 80% chance
Cookeville: upper 70's to low 80's; 80% chance
Columbia: mid to upper 80's; 80% chance
Manchester: low to mid 80's; 80% chance
