ᴱQ. kalle “fair weather, clear sky, blue sky” appeared in the Qenya Lexicon as a derivative of the root ᴱ√KALA “shine golden” (QL/44). It also appeared in the Poetic and Mythological Words of Eldarissa with gloss “fair weather” (PME/44).
Neo-Quenya: I think this word might be salvaged as ᴺQ. callë, since the later root √KAL was still associated with light, and this description of fair weather seems to boil down to “lightness”, as in the absense of obscuring clouds.
