Severe thunderstorms are expected across parts of Middle Tennessee on Friday. The most likely time window is late afternoon through the evening. The most likely area to be impacted is southern Kentucky and communities east of I-24.
Outdoors as of 9am today, it was already very warm.
Humidity was reasonable for late July, with most dew points running in the 60s.
This afternoon, isolated showers and thundershowers will be possible. Western Middle Tennessee runs the highest chance of picking up any rain today.
Highs this afternoon will be in the 90s for most of us.
Tonight, higher humidity will overspread the entire Mid State. Tomorrow will turn hot and be oppressively muggy. Those two factors combined with a bundle of energy moving in in the upper atmosphere will make for scattered strong to severe thunderstorms late tomorrow and tomorrow night.
Northern Middle Tennessee, the Cumberland Plateau, and southern Kentucky are at greatest risk. There, the threat is classified as “enhanced” which is a level 3 threat on a scale of 1 to 5. The rest of the Mid State is in a level 2 threat area, which is still reflective of a good chance of scattered strong-severe thunderstorms. The “marginal risk” area shows where severe storms are least likely, but still possible.
Breaking down the threats tomorrow, large hail (golf ball size in some instances), damaging wind gusts, and isolated tornadoes will all be possible. Flash flooding will be unlikely due to the fact that storms will be moving along at a good rate of speed.
