For future knowledge, TUTTs (or Tropical Upper Tropospheric Troughs) have a very long gestation period before they will convert to warm core; doing so through the entire depth of the troposphere (the region of the atmosphere between ~ the 100mb level and the surface) is an undertaking. While TUTTs, the clouds and shower activity are being driven by deep layer instability, in the form of cold air and associated low pressure aloft promoting lift, resulting convection and thunderstorms. But, the physics of this process are completely different than the physics of tropical cyclone genesis.

So we (Florida) are in the TUTT? So are all TUTTs cold air? And is that what they mean when they refer to cyclones as "warm core?"

I watched it on radar yesterday as it unfolded. We had a wicked line of storms come through late yesterday. I could see the faint spin between the satellite and the radar. It was interesting to see how the afternoon "flare up" (the traditional line of storms down the ridge of the state from the seabreeze) just bloomed and then sort of merged and started moving with the stuff generated by the low.

Thank you for taking the time to explain that to me. I appreciate knowledge on this board!
