Although there could be some strong morning storms, the most concerning are the ones that could develop in the afternoon and overnight hours through early Thursday morning.

Along with a line of strong storms that will push in overnight, there is also the possibility that some individual “supercell” thunderstorms could develop ahead of that line.

The Storm Prediction Center has put most of Middle Tennessee under an “Enhanced” threat for severe weather. That is a new category they added between “Slight” and “Moderate”. They issue that when they see a 30 percent chance for severe weather two days in advance.

The Tennessee Emergency Management Agency told News 2 they will assess the situation Wednesday at 9 a.m.

For weather enthusiasts, here is some of their wording for our area:

“Lower Mississippi Valley to the Tennessee Valley and vicinity during peak-heating with at least pockets of supporting steepening low-level rates across this area and an influx of modestly steep mid-level lapse rates. Supercell development will be more likely in this region. This will be aided by 50-60 kt of deep shear oriented with at least some orthogonal component to the SFC boundary. With 60-70 kt of h7 flow above 45-55 kt of h85 flow. Low-level shear will be adequate for tornadoes, some potentially signifidant. Dmgg wind gusts and hail may also accompany this activity.”
