“ Based solely on Jupiter’s distance from the sun, its upper atmosphere should be about -100 F (-73 C). But observations show Jupiter’s upper atmosphere instead soars to temperatures of 800 F (426 C).”

Many have thought about life in the upper parts of Jupiter’s atmosphere (https://en.m.wikipedia.org/wiki/Jupiter_in_fiction). There’s some water, it’s hot, and the super lightning bolts add extra energy. The main problem it seems for small microorganisms is staying at the hospitable height: https://www.missionjuno.swri.edu/jupiter/atmosphere?show=hs_...

If there’s some sort of pocket/eddy that keeps a portion of the atmosphere at constant height continuously that might be a suitable place for early life.
