...or something like that

there's a very faint irony in the Italian "accessorie" -maybe you can get it into the English as well

… foreseeable mishaps that would have brought with it,

Another possibility.

I did a quick google search on the phrase, and those words seem to be only used together in reference to money, meaning incidentals - as in incidental costs, but I think in this piece there is some kind of pun on the word 'schiacciare' like 'schiacciato' the tuscan flatbread, and 'grane' like grain for bread, so maybe you could substitute the colloquial term 'dough' for costs to remain true to this, and say the sky looks like it's about to flatten the day like a pancake to keep the connection going, that is, if the piece's register allows for this kind of informal language. If not, incidental costs should be fine, or if you want to keep with the notion of challenges, just 'incidentals' on its own, as this can mean incidental costs, or just burdens/annoyances, or both.
