thundery
Ominously rumbling overhead
Thundery describes weather that suggests or produces thunder—dark, heavy, and charged with the threat of a storm: The sky turned thundery by late afternoon.
The word is more common in British English than American, where *stormy* or *threatening* typically fill the same role.
