I got my question answered this morning -- both NBC2 in Ft. Myers and TWC in their 6 a.m. hour Tropical Update mentioned the upper level low. They both said the predicted result will be an increase in weekend showers, but neither indicated any reasonable chance of developing into anything other than a rain system.
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.
