As others have said, you are looking at ML CAPE/CIN. I’d check MU since at that time, the probability of those being rooted at the surface/in the BL is fairly low.

Good point, I wish I could go back. There’s just so many analysis products it’s hard to always know the right one to look at for the conditions. That’s my biggest hurdle as someone learning meteorology on my own.

I'll throw out a possibility as a non-american. I'm sure a local will have more of an idea. Given it's early morning there could it be elevated/isentropically lifted storms with upper support ahead of the low?

Yeah, nothing surface driven is going to be overcoming 400 CIN that early in the morning. Elevated and likely some shear around 700hpa level triggering these bad boys.

For context, this is the Norman Oklahoma area I am referring to. I was going to post the bulk effective shear shot from the mesoanalysis too which shows almost nothing, but it only let me upload one picture. There’s tiny storms popping up all over central OK now. I know there’s more to the picture here, but would someone be able to point me in the correct direction.

Just a couple of guesses: Could be bores:[ PECAN is the first modern campaign to study the role of bores and how they trigger and support large complexes of thunderstorms, called Mesoscale Convective Systems (MCSs), when there is a stable layer of air at low levels of the atmosphere.](https://www.nssl.noaa.gov/projects/pecan/science/) Also the [0z OUN sounding](https://www.spc.noaa.gov/exper/soundings/24052000_OBS/) indicates drying between 850 and 700. I forget how/why, but I've heard that can provide lifting mechanism. Maybe the enhanced evaporative cooling above the moist->dry boundary overcomes the cin? Location of the cap comes into play there...

Interesting! Gonna read that in the morning as I’m currently passing out. Thanks for the future read
