We did have storms develop over parts of our NC area which prompted us to jump into severe coverage mode – putting us behind in current & forecast updates. Aside from earlier, our area currently has light/moderate CAPE in the 500-1,200 J/Kg range which is supportive for showers/storms later on. HRRR model shows numerous widespread showers developing west of I-75 around 0z which should weaken as they move east due to lower CAPE and a somewhat moderate CAP in place. On the topic of CAP, there is a weak CAP over the plateau according to NAM and HRRR of -26 which will be relatively easy to break if a storm can get to that point. Moving into NE TN the CAP becomes much stronger at -149 which will take a little bit more for a storm to break. All in all, I think the best chance for heavy showers and storms will be west of I-75. While most of the area has a good chance of shower activity tonight, the more intense areas will be in the plateau.
Dewpoints remain in the 50s & 60s with temps in the 70s / lower-80s.
